A new Uiwix ransomware variant has been detected using EternalBlue to gain access to vulnerable systems. Businesses that have not yet patched they systems are vulnerable to this new attack.
In contrast to the WannaCry ransomware variant that was used in Friday’s massive ransomware campaign, Uiwix ransomware is a fileless form of ransomware that operates in the memory. Fileless ransomware is more difficult to detect as no files are written to the hard drive, which causes problems for many antivirus systems. Uiwix ransomware is also stealthy and will immediately exit if it has been installed in a sandbox or virtual machine.
Trend Micro reports that the new Uiwix ransomware variant also “appears to have routines capable of gathering the infected system’s browser login, File Transfer Protocol (FTP), email, and messenger credentials.”
As with WannaCry ransomware, the ransomware is not being spread via email. Instead the attackers are searching for vulnerable systems and are taking advantage of SMB vulnerabilities and attacking computers over TCP port 445. Infection with Uiwix sees the Uiwix extension added to encrypted files. The ransom demand to supply keys to decrypt locked files is $200.
The threat does not appear to be as severe as WannaCry, as the attackers are manually targeting vulnerable systems. Crucially, the ransomware lacks the wormlike properties of WannaCry. If one machine is infected, the ransomware will not then spread to other networked devices.
Since the WannaCry attacks, many businesses have now implemented the MS17-010 patch and have blocked EternalBlue attacks. Microsoft has also released a patch for Windows XP, Windows Server 2003, and Windows 8, allowing users of older, unsupported Windows versions to secure their systems and prevent attacks.
However, the search engine Shodan shows there are still approximately 400,000 computers that have not yet been patched and are still vulnerable to cyberattacks using the EternalBlue exploit.
Another threat that uses the EternalBlue and DoublePulsar exploits is Adylkuzz; however, the malware does not encrypt data on infected systems. The malware is a cryptocurrency miner than uses the resources of the infected computer to mine the Monero cryptocurrency. Infection is likely to see systems slowed, rather than files encrypted and data stolen.
Other malware and ransomware variants are likely to be released that take advantage of the exploits released by Shadow Brokers. The advice to all businesses is to ensure that software is patched promptly and any outdated operating systems are upgraded. Microsoft has issued a patch for the older unsupported systems in response to the WannaCry attacks, but patches for Windows Server 2003, Windows XP and Windows 8 are unlikely to become a regular response to new threats.
An Edmodo data breach has been reported that has impacted tens of millions of users of the education platform, including teachers, students and parents.
Edmodo is a platform used for K-12 school lesson planning, homework assignments and to access grades and school reports. There are currently more than 78 million registered users of the platform. The hacker responsible for the Edmodo data breach claims to have stolen the credentials of 77 million users.
The claim has been partially verified by Motherboard, which was provided with a sample of 2 million records that were used for verification purposes. While the full 77 million-record data set has not been checked, it would appear the claim is genuine.
The hacker, nclay, has listed the data for sale on the darknet marketplace Hansa and has asked to be paid $1,000 for the entire list. The data includes usernames, hashed passwords and email addresses. Email addresses for around 40 million users are believed to have been obtained by the hacker.
The passwords have been salted and encrypted using the bcrypt algorithm. While it is possible that the passwords can be decrypted, it would be a long and difficult process. Edmodo users have therefore been given a little time to reset their passwords and secure their accounts.
The Edmodo data breach is now being investigated and third party cybersecurity experts have been contracted to conduct a full analysis to determine how access to its system was gained. All users of the platform have been emailed and advised to reset their passwords.
Even if access to the accounts cannot be gained, 40 million email addresses would be valuable to spammers. Users of the platform are likely to face an elevated risk of phishing and other spam emails, should nclay find a buyer for the stolen data.
This is not the only large-scale data breach to affect the education sector this year. Schoolzilla, a data warehousing service for K-12 schools, also experienced a major cyberattack this year. The data breach was discovered last month and is believed to have resulted in the theft of 1.3 million students’ data. In the case of Schoolzilla, the hacker took advantage of a backup file configuration error.
The WannaCry ransomware attacks that crippled hospitals in the United Kingdom on Friday have temporarily halted, although not before infections spread to 150 countries around the globe. The massive ransomware campaign saw 61 NHS Trusts in the UK affected.
As the NHS was cancelling appointments and scrambling to halt the spread of the infection and restore its systems, the WannaCry ransomware attacks were going global. Organizations around the world were waking up to total chaos, with systems taken out of action and data access blocked. Other victims include FedEx, Telefonica, Deutsche Bahn and the Russian Interior Ministry and around 200,000 others.
The victim count rose considerably throughout Friday and Saturday morning, before a security researcher in the UK accidentally flicked the ransomware’s kill switch, preventing further WannaCry ransomware attacks. Had it not been for that researcher’s actions, the victim count would have been considerably higher.
The researcher in question prefers to remain anonymous, although he tweets under the Twitter account @MalwareTechBlog. While analyzing the ransomware, he discovered a reference to a nonsense web domain. He checked to see who owned the domain and discovered it had not been registered. He bought it and realized that his actions had stopped the ransomware in its tracks. If the domain could be contacted, encryption would not take place. If contact was not possible, the ransomware would proceed and encrypt files on the infected device.
This kill switch could have been put in place by the authors as a way to stop infections getting out of control. However, far more likely is the domain check was performed to determine if the ransomware was running in a test environment.
For now at least, the WannaCry ransomware attacks have stopped, although that does not mean they will not continue. New versions of the ransomware – without the kill switch – will almost certainly be released. In the meantime, IT security professionals have some time to plug the vulnerability that was exploited.
The exploit takes advantage of a vulnerability in Windows Server Message Block (SMB) that allows the attackers to download files onto a vulnerable machine. Microsoft issued a patch to plug the vulnerability on March 13 (MS17-010). Even though this was a high priority patch for which an exploit had been developed (ETERNALBLUE) and released online, many companies failed to update Windows leaving them vulnerable to attack.
Of course, any organization using an unsupported version of Windows – Windows XP for example – would not be able to apply the patch. Many NHS Trusts in the UK still use the unsupported version of Windows even though it is vulnerable to this and other exploits.
The attackers have reportedly made around $50,000 so far from the WannaCry ransomware attacks. That figure will rise, as victims are given 7 days to pay before the decryption keys held by the attackers will be permanently deleted. If payment is not made within 3 days, the $300 ransom doubles.
There are no clues as to who was behind the attack, although it was made possible by the actions of the hacking group Shadow Brokers, who published the exploit used in the WannaCry ransomware attacks in April. The exploit was not developed by Shadow Brokers however. That appears to have been developed by the National Security Agency in the USA. Shadow Brokers allegedly stole the exploit.
Microsoft has responded to the WannaCry ransomware attacks saying they should serve as a “wake-up call.” That’s not just the need to apply patches promptly to prevent cyberattacks, but also a wake up call for governments not to secretly stockpile exploits.
A Mac malware warning has been issued for any individual who recently downloaded Handbrake for Mac. A server was compromised and a remote access Trojan was bundled with the Handbrake Apple Disk Image file.
A credential-stealing Remote Access Trojan was discovered to have been bundled with the Handbrake video transcoder app for the MacOS, with Handbrake for Mac downloads between May 2 and May 6, 2017 potentially also installing the MacOS Proton RAT.
A Mac malware warning has been issued for all users who recently downloaded the app. It is strongly recommended that any individual who downloaded the app between the above dates verifies that they have not been infected. According to a statement issued by the developers of the app, individuals have a 50/50 change of infection if they downloaded the app between the above dates.
Cybercriminals were able to compromise a server and bundle the malware with the app, with all users who used the download.handbrake.fr mirror potentially infected.
Apple has now updated its OSX’s XProtect to detect and remove the infection although individuals at risk should check to see if their device has been infected. Infection can be detected by looking for the Activity_agent process in the OSX Activity Monitor. If the process is running, the device has been infected with the Trojan.
Any user infected with the malware will need to change all passwords stored in the MacOS keychain. Any password stored in a browser will also need to be changed, as it is probable it has also been compromised.
The Trojan can be easily removed by opening the Terminal and entering the following commands before removing all instances of the Handbrake app:
if ~/Library/VideoFrameworks/ contains proton.zip, remove the folder
The MacOS Proton RAT was first identified earlier this year. It is capable of logging keystrokes to steal passwords, can execute shell commands as root, steal files, take screenshots of the desktop and access the webcam. Once installed, it will run every time the user logs on.
Only Handbrake for Mac downloads were affected. Any user who recently upgraded through the Handbrake update mechanism will not be affected, as checks are performed to prevent the downloading of malicious files.
The compromised server has now been shut down to prevent any further malware downloads. At this stage it is unclear how access to the server was gained and how the Handbrake Apple Disk Image file was replaced with a malicious version.
A patch has been rushed and released to address a serious Microsoft Malware Protection Engine bug, termed ‘Crazy Bad’ by the researchers who discovered the flaw. If exploited, the vulnerability would allow threat actors to turn the malware protection software against itself.
If the Microsoft Malware Protection Engine bug is exploited, Microsoft’s malware protection engine could be used to install malware rather than remove it. Instead of searching for infected files that have been downloaded, the system would be downloading malware and infecting end users.
The Microsoft Malware Protection Engine bug affects a number of anti-malware software products including Windows Defender, Microsoft Security Essentials, Microsoft System Center Endpoint Protection, Microsoft Forefront Security for SharePoint, Microsoft Endpoint Protection, Windows Intune Endpoint Protection and Microsoft Forefront Endpoint Protection.
The remotely exploitable bug could allow a system to be completely compromised, giving attackers full access to an infected computer or server, since the software and all associated processes run at LocalSystem privilege level.
The flaw was discovered by Natalie Silvanovich and Tavis Ormandy of Google Project Zero who alerted Microsoft three days ago. Ormandy said the flaw was “The worst in recent memory.” Microsoft worked fast to patch the flaw and an update was pushed out yesterday.
While extremely serious, Microsoft does not believe any malicious actors have taken advantage of the flaw, although all unpatched systems are at risk. Threat actors could take advantage of the Microsoft Malware Protection Engine bug in a number of ways, including sending specially crafted email messages. The Project Zero researchers note that simply sending a malicious email would be enough to allow the bug to be exploited. It would not be necessary for the user to open the email or an infected email attachment. The researchers explained that “writing controlled contents to anywhere on disk (e.g. caches, temporary internet files, downloads (even unconfirmed downloads), attachments, etc) is enough to access functionality in mpengine.” Alternatively, the flaw could be exploited by visiting a malicious website if a link was sent via email or through instant messaging.
The patch for the vulnerability (CVE-2017-0290) will be installed automatically if users have auto-update turned on. System administrators who have set updates to manual should ensure the patch is applied as soon as possible to prevent the flaw from being exploited. The current, patched Malware Protection Engine is version 1.1.13704.0.
A sophisticated new malware threat has been discovered that is being used to target a wide range of industry sectors and infect systems with RAT/malware.
The campaign is being used to spread multiple malware variants and gain full access to systems and data. While many organizations have been attacked, the threat actors have been targeting IT service providers, where credential compromises can be leveraged to gain access to their clients’ environments.
The threat actors are able to evade detection by conventional antivirus solutions and operate virtually undetected.
The campaign has been running since at least May 2016 according to a recent alert issued by the National Cybersecurity Communications Integration Center (NCCIC) of the U.S. Department of Homeland Security.
The campaign is still being investigated, but due to the risk of attack, information has now been released to allow organizations to take steps to block the threat and mitigate risk. NCCIC categorizes the threat level as medium.
While threat detection systems are capable of identifying intrusions, this campaign is unlikely to be detected. The attack methods used by the threat actors involve impersonating end users leveraging stolen credentials. Communications with the C2 are encrypted, typically occurring over port 443 with the domains frequently changing IP address. Domains are also spoofed to appear as legitimate traffic, including Windows update sites.
Two main malware variants are being used in this campaign – the remote administration Trojan (RAT) REDLEAVES and the PLUGX/SOGU Remote Access Tool. PLUGX malware has been around since 2012, although various modifications have been made to the malware to prevent detection.
PLUGX allows the threat actors to perform a range of malicious activities such as setting connections, terminating processes, logging off the current user and modifying files. It also gives the threat actors full control of the compromised system and allows the downloading of files. READLEAVES offers the threat actors a typical range of RAT functions including system enumeration.
NCCIC has released Indicators of Compromise (IOCs) to allow organizations to conduct scans to determine whether they have been infected and further information will be published when it becomes available.
While anti-virus solutions should be used, they are unlikely to offer protection against this malware campaign. NCCIC warns organizations that there is no single security solution that can prevent infection, therefore a multi-layered defense is required. The aim of organizations should be to make it as difficult as possible for the attackers to gain access to their systems and install malware and operate undetected.
NCCIC offers several suggestions to help organizations improve their defenses against attack. Since phishing emails are used to fool end users into revealing their credentials, anti-phishing solutions should be employed to prevent the emails from reaching end users’ inboxes.
Sabotage, subversion and ransomware attacks all increased sharply in 2016, with malware-infected emails now at a five-year high according to the latest installment of Symantec’s Internet Security and Threat Report (ISTR).
For the 22nd volume of the report, the antivirus and antimalware software vendor analyzed data collected from millions of users of its security solutions – The world’s largest civilian threat collection network, consisting of 98 million attack sensors spread across 157 countries around the globe.
The 77-page Internet Security and Threat Report is one of the most highly respected publications issued by any cybersecurity company.
The Internet Security and Threat Report provides a valuable insight into the state of cybersecurity and details how global cybersecurity threats have changed over the course of the past 12 months.
Internet Security and Threat Report Shows Change in Attack Tactics
Data theft and financial fraud may be major motivators behind cyberattacks on businesses, but over the past 12 months there has been a sharp rise in politically motivated cyberattacks. Rather than steal data, the attackers are sabotaging businesses using destructive malware such as hard disk wipers.
The attacks are conducted to cause serious harm to business competitors, although nation state-backed hackers have also been targeting the critical infrastructure in many countries. Attacks on Ukrainian energy providers have been conducted to disrupt the power supply while attacks on companies in Saudi Arabia – using Shamoon malware – attempted to permanently delete corporate data.
Many attacks were conducted last year with a different aim – subversion. That was clearly demonstrated during the recent U.S presidential campaign. Sensitive data from the Democratic party was leaked in an attempt to influence the outcome of the U.S presidential election. The FBI investigation into the hacking of the presidential election is ongoing.
Sabotage is on the rise, but data theft incidents continue. The past year has seen many espionage attacks resulting in the theft of sensitive data and corporate secrets and financial attacks have increased.
The Internet Security and Threat Report shows there has been a major increase in large-scale financial heists in the past year. Attacks on consumers are occurring with increasingly regularity, although the banks themselves are now being targeted. Those attacks have resulted in the theft of many millions of dollars.
The Carbanak gang has been highly active in this area and has performed multiple attacks on U.S banks, while the Banswift group performed one of the biggest heists of the year, stealing $81 million from the central bank in Bangladesh.
While exploit kits and other web-based attacks were a major threat in 2015, attackers have returned to email as the primary method of gaining access to networks. In 2015, Symantec blocked an average of 340,000 web-based attacks per day. In 2016, the number had fallen to 229,000 – a significant reduction, although the threat of web-based attacks cannot be ignored.
The Biggest Malware Threat Comes from Email
Phishing is still a major risk for businesses, although the phishing rate has fallen over the past three years, according to the Internet Security and Threat Report. In 2014, one in 965 messages were used for phishing. In 2016, the number fell to one in 2,596 emails.
However, email spam levels have remained constant year on year. Email spam accounts for 53% of all sent messages.
Phishing email volume may be down, but email-borne malware attacks have increased. The Symantec Internet Security and Threat Report shows the volume of malicious emails now being sent is higher than any point in the past five years.
Now, one in 131 emails contain either a malicious attachment or hyperlink, up from one in 220 emails in 2015 and one in 244 emails in 2014. The number of new malware variants being released has also soared. In 2014, there were 275 million new malware variants discovered. That figure rose to 357 million last year. The number of bots sending malicious email has also increased year on year, from 91.9 million in 2015 to 98.6 million in 2016.
Ransomware Attacks Soared in 2016
Ransomware attacks also increased significantly in 2016, with the United States the most targeted country. Even though the FBI and other law enforcement agencies strongly advise against paying a ransom, 64% of U.S. companies ignore that advice and pay the attackers for keys to decrypt their data.
In 2015, the average ransom demand was for $294 per infected machine. Over the course of the past 12 months, ransom amounts have increased considerably. The Symantec Internet Security and Threat Report shows ransom demands increased by an astonishing 266% in 2016. The average ransom demand is now $1,077 per infected machine.
Symantec tracked 101 separate ransomware families in 2016 – A substantial rise from the 30 known ransomware families in 2014 and 2015. Last year, there were 463,841 ransomware detections, up from 340,655 from 2015.
One of the biggest threats comes from the cloud, although many organizations are underestimating the risk. When organizations were asked how many cloud apps are in use in their company, few provided an accurate figure. Many estimated they used around 40 cloud-based apps. Symantec reports that for the average company, the figure is closer to 1,000.
As the Internet Security and Threat Report shows, the cyberthreat landscape is constantly changing as cybercriminals develop new methods of attacking businesses. Only by keeping up to date on the latest threat indicators and bolstering cybersecurity defenses can businesses maintain a robust security posture and prevent attacks.
The GDPR impact on business practices is considerable, as is the cost of GDP compliance. A recent survey conducted by PwC revealed that 77% of large companies are expecting GDPR compliance to cost in excess of $1 million. Due to the considerable GDPR impact on business practices, many companies are already rethinking whether or not to continue doing business in Europe.
Many large multinational companies are well aware of the GDPR impact on business practices and the amount of work GDPR compliance will involve. That is not the case for SMEs, many of which are only just realizing they must comply with GDPR.
GDPR does not just apply to social media sites and global retailers. All businesses, regardless of their size, will be required to comply with the General Data Protection Regulation if they collect or process the personal information of EU citizens.
The definition of personal information is broad and includes online identifiers such as IP addresses. Even online retailers that allow EU citizens to access their websites are required to comply with GDPR.
All businesses will be required to perform a risk analysis to identify potential vulnerabilities to the confidentiality and integrity of stored data. Many large companies already have a swathe of cybersecurity protections to keep sensitive data secure, but most smaller organizations will discover they must implement more robust cybersecurity protections in order to comply with GDPR.
Companies will need to review their policies on data collection. When GDPR comes into effect, companies will need to have a valid reason for collecting personal information. Any data collected must also be limited to the minimum necessary information to perform the purpose for which data are collected.
Doing business in Europe will require privacy protections to be enhanced, new data security measures to be implemented, data collection practices to be changed, and policies and procedures to be updated. Legal teams must then assess GDPR compliance.
The GDPR impact on business practices is likely to be considerable for many companies. The time taken to perform risk analyses, assess policies and procedures, find and implement security solutions and update privacy policies will be considerable. Leaving GDPR compliance to the last minute is likely to see the deadline missed. That could prove to be very costly or even catastrophic for many businesses. Failure to comply with GDPR regulations can result in a fine of €20 million or 4% of global revenue, whichever is the greater. Non-compliance simply isn’t an option.
Kaspersky Lab has released new figures showing software exploit attacks increased by almost a quarter in 2016. In total, more than 702 million attempted software exploit attacks were performed; a rise of 24.54% year on year. Corporate users were the worst affected, registering 690,000 attacks in 2016; a rise of 28.35% year on year.
According to the report, 69.8% of software exploit attacks took advantage of flaws in web browsers, Microsoft Windows, Microsoft Office or the Android platform. Software exploit attacks involve malware leveraging flaws in software to run malicious code or install other malware. Last year, the most common exploit took advantage of the Stuxnet vulnerability on unpatched systems.
Software exploits are difficult to identify because they occur silently without alerting the user. Unlike email-based attacks, software exploits require no user interaction. A user must only be convinced to visit a website hosting an exploit kit. A hyperlink can be sent via email or users can be redirected to malicious sites using malvertising. Attacks can occur through general web browsing. Hackers often take advantage of flaws to hijack websites and install exploit kits.
While attacks on companies have increased, attacks on private users fell by around 20% to 4.3 million attacks. This has been attributed to two major exploit kits – Neutrino and Angler – being shut down. Without those exploit kits, criminal groups have lost the ability to spread malware and have had to resort to different tactic to spread malware, with spam email the delivery mechanism of choice.
Exploit kits are expensive to develop and require considerable work, and since software developers are reacting faster and patching vulnerabilities, exploit kits are no longer as profitable for cybercriminals. However, exploits are still being used by sophisticated criminal gangs in targeted attacks aimed at stealing highly sensitive data.
This year has seen an increase in exploit activity using the Rig exploit kit, while last month Checkpoint noted a major rise in software exploit attacks.
Exploit kits may not pose as big a threat as in late 2015, but they are still a significant threat for businesses. Organizations can improve their defenses against software exploits by installing patches promptly and ensuring anti-virus and anti-malware solutions are kept up to date. A web filtering solution should also form part of organizations’ defenses. Web filters prevent end users from visiting, or being redirected to, websites known to host exploit kits.
On May 25, 2018, the General Data Protection Regulation (GDPR) comes into force and GDPR compliance will be mandatory. Now is the time to get prepared. GDPR compliance is likely to require considerable effort and resources. If your organization is not prepared, you may miss the GDPR compliance deadline.
GDPR is a new regulation that will apply to all organizations based in EU member states, as well as those based in non-member states that capture, hold or process the data of EU citizens. GDPR is a replacement of the 1995 EU Data Protection Directive and will address web-based technology that was not widely available in 1995. Use of the cloud for instance.
The new regulation will help to ensure the personal data of EU citizens is protected and the risk of sensitive data being exposed is minimized. The new regulation will also allow EU citizens to have much greater control over the personal data that is collected and stored by organizations, and how those data are used.
How Will GDPR Protect Consumers?
One of the main elements of GDPR is improving the rights of EU citizens with regards to the personal data that is collected, stored and used by organizations. GDPR requires organizations to obtain informed consent from consumers prior to collecting and using their data. Consumers must be told the reason why data are being collected, how data will be used, and consumers must be told that they can withdraw their consent at any time. A mechanism must be put in place that will allow an organization to delete data when it is no longer required or when consent is withdrawn.
GDPR gives consumers the right to:
Find out how their data will be used
Discover how data were obtained if informed consent was not provided
Access personal data
Find out how long data will be stored
Correct errors in stored data
Move data to a different processor
Restrict or prohibit the processing of data
Find out with whom data have been or will be shared
Have data permanently erased
Avoid being evaluated on the basis of automated processing
Organizations must also limit the data collected to the minimum necessary amount for the purpose that has been described to consumers to be performed.
While organizations that have an online presence and actively collect data will have to comply with GDPR – Amazon for example – GDPR will apply to a much broader range of companies. In fact, many companies that do not have an online presence will need to comply with GDPR. GDPR will apply to any company that collects the types of data covered by the GDPR definition of personal information. That includes organizations that store ‘personal data’ of employees in an electronic database.
What Data are Covered by GDPR?
Under GDPR, personal information includes an individual’s name and a host of other identifiers, including online identifiers such as location data, IP addresses, cookies and other “pseudonymous data”. Information such as race and ethnic origin, religious or philosophical beliefs, political opinions, sexual orientation, details of sex life, criminal convictions, trade union membership, health data, biometric data, and genetic data are all covered.
Data Security Standards Necessary for GDPR Compliance
GDPR also covers the protections that must be put in place by organizations to ensure the confidentiality, integrity, and availability of data. That includes stored data and all data that flows through systems or applications.
GDPR compliance requires organizations to conduct a risk/gap analysis to assess potential vulnerabilities in their current systems and processes.
Companies must “implement appropriate technical and organizational measures” to ensure the confidentiality, integrity and availability of data. Those measures should “ensure a level of security appropriate to the risk.”
Companies must adopt a privacy and security-by-design approach, and ensure that controls are implemented during the planning stages, development, implementation, and use of applications and systems. Regular testing and security assessments must also be performed.
Systems must also be implemented that allow data to be recovered and restored in the event of a security incident or technical problem being experienced.
Data Breach Notification Requirements of GDPR
Any organization that experiences a breach of data covered by GDPR must inform their Data Protection Authorities (DPAs) within 72 hours of the breach being discovered. Individuals impacted by a data breach must also be notified, if such a breach has potential to result in identity theft or fraud, discrimination, financial loss, reputation damage, or other significant economic or social disadvantage. Notifications will not be required if stored data are encrypted or are otherwise undecipherable and unusable.
Preparing for GDPR
Many organizations currently lack the necessary systems to ensure GDPR compliance. For instance, many do not have systems that allow them to easily identify consumer data, retrieve it, and delete it as necessary.
Privacy policies will need to be drafted and published to incorporate the new regulation and ensure GDPR compliance. Forms explaining consent to use data will need to be developed and published. Staff will need to be trained on the new rights of individuals. Policies must also be developed – or updated – covering data breach notifications in case personal information is exposed, accessed, or stolen. Additional security solutions will need to be implemented. GDPR compliance will involve considerable cost and resources and ensuring GDPR compliance will take time.
Organizations must therefore start preparing for the introduction of the new regulation. It may be a year before GDPR compliance is necessary, but given the necessary changes, organizations should start planning now. From May next year, GDPR compliance will be mandatory and there will be severe penalties for non-compliance.
What are The Penalties for Non-Compliance with GDPR?
Any organization that fails to comply with GDPR can be fined by their DPAs. DPAs will be given more powers to investigate data breaches and non-compliance. The potential fines for non-compliance with GDPR are considerable.
If an organization does not comply with the GDPR security standards, a fine of up to €10 million can be issued or 2% of global annual turnover, whichever is the greater. The failure to comply with GDPR privacy standards can attract a fine of up to €20 million or 4% of global annual turnover, whichever is the greater.
Fines will be dictated by the extent of the violation or data breach, the number of individuals impacted, and the extent to which the organization has implemented controls and standards to ensure GDPR compliance.
Individuals also have the right to seek compensation if their personal information is misused or stolen, if they have suffered harm as a result. Criminal sanctions may also be applied, such as if data is collected without consent.
Organizations are likely to suffer reputational damage in the event of a data breach, as the EU will be naming and shaming organizations that fail to implement appropriate measures to protect data and prevent data breaches. Details of organizations that have not complied with GDPR will be published and made available to the public.

A recent Chipotle Mexican Grill security breach has potentially resulted in customers’ credit card details being accessed by unauthorized individuals.
A statement released by the fast casual restaurant chain confirms that unauthorized individuals gained access to its network hosting its payment processing system. The initial findings of its investigation suggest access was first gained on March 24, 2017. Customers who visited its restaurants between March 24 and April 18, have potentially been affected. The investigation into the Chipotle Mexican Grill security breach is continuing to determine how many of the chain’s 2,000+ restaurants have been affected.
Few details about the Chipotle Mexican Grill security breach have been released as the investigation is ongoing, although the threat is now believed to have been blocked.
Chipotle Mexican Grill called in external cybersecurity experts to investigate a potential breach after unusual activity was detected on the network hosting its payment processing system. Law enforcement was alerted, as was its payment processor. Additional security protections have already been installed to bolster cybersecurity defenses in response to the suspected attack. Efforts are continuing to confirm the exact dates of the attack and the restaurants that have been affected.
The Chipotle Mexican Grill security breach is one of many incidents reported by restaurant chains this year. Restaurants are being targeted by cybercriminals due to the high number of credit cards that are processed. If attackers can gain access to restaurant payment processing systems, many thousands of credit card numbers can be stolen.
There are many methods used by cybercriminals to gain a foothold in a network and gain access to payment processing systems.
Typically attacks occur as a result of an employee opening an infected email attachment or visiting a hyperlink in an email that allows malware to be downloaded. Phishing emails are also sent, which aim to get employees to reveal their login credentials. Restaurants can improve their resilience against email-borne attacks by implementing an advanced spam filtering solution.
Web-borne attacks are also common. A recent report from Symantec shows web-based attacks have increased in the past year.
If an employee can be convinced to visit a malicious website, or is directed to such a site via a malvertising campaign, malware can be silently downloaded. Exploit kits on malicious websites probe for vulnerabilities in browsers and exploit those vulnerabilities to download malware.
Web-borne attacks can be prevented by ensuring that patches are applied promptly and all vulnerabilities are plugged. However, the number of patches now being released makes it difficult for restaurants to keep up. New zero day vulnerabilities are also constantly being discovered and added to exploit kits.
Many restaurants are improving their defenses against web-based attacks by implementing a web filtering solution. A web filter can be used to carefully control the websites that can be accessed on restaurant computers.
Web filters block all known malicious websites using black lists. As soon as a website is discovered to be hosting an exploit kit, malware, or used for phishing, it is added to blacklists and the site is blocked by the web filter.
A web filter is also an excellent phishing defense. If an employee clicks on a phishing hyperlink in an email, the web filter can block the URL and prevent the user from visiting the site.
There are other important advantages to implementing a web filtering solution for restaurants. The solution can be used to carefully control the websites that customers can access. Restaurants can therefore ensure that customers do not access malicious sites or inappropriate website content such as pornography. Consumers are increasingly seeking restaurants that offer free Wi-Fi, but also those that implement controls to secure their Wi-Fi networks.

Locky is back. The latest Locky ransomware attacks leverage an infection technique used in Dridex malware campaigns.
It has been all quiet on the western front, with Locky ransomware attacks dropping off to a tiny fraction of the number seen in 2016. In the first quarter of 2017, Locky ransomware campaigns all but stopped, with Cerber becoming the biggest ransomware threat.
That could be about to change. Locky has returned, its delivery mechanism has changed, and the crypto ransomware is now even harder to detect.
The latest campaign was detected by Cisco Talos and PhishMe. The Talos team identified a campaign involving around 35,000 spam emails spread over just a few hours. The researchers suggest the emails are being delivered using the Necurs botnet, which has until recently been used to send out stock-related email spam.
New Infection Method Used in Latest Locky Ransomware Attacks
The latest Locky campaign uses a different method of infection. Previous Locky campaigns have used malicious Word macros attached to spam emails. If the email attachment is opened, end users are requested to enable macros to view the content of the document. Enabling macros will allow a script to run that downloads the payload. For the latest campaign, spam emails are used to deliver PDF files.
The change in infection method can be easily explained. Over the past few months, Word macros have been extensively used to infect end users with ransomware. Awareness of the danger of Word macros has been widely reported and companies have been warning their staff about malicious Word documents containing macros.
If an end user is fooled into opening an email attachment that asks them to enable macros, they are now more likely to close the document and raise the alarm. To increase the probability of the end user taking the desired action, the authors have made a change. Macros are still involved, but later in the infection process.
The emails contain little in the way of text, but inform the recipient that the PDF file contains a scanned image or document, a purchase order, or a receipt. PDF files are more trusted and are more likely to be opened. Opening the PDF file will see the user prompted to allow the PDF reader to download an additional file. The second file is a Word document containing a macro that the end user will be prompted to enable.
The rest of the infection process proceeds in a similar fashion to previous Locky ransomware attacks. Enabling the macros will see a Dridex payload downloaded which will then download Locky. Locky will proceed to encrypt a similarly wide range of file types on the infected computer, connected storage devices and mapped network drives.
The ransom payment demanded is 1 Bitcoin – currently around $1,200. This is considerably more that the ransom payments demanded when Locky first arrived on the scene just over a year ago.
One slight change for this campaign is the user is required to install the Tor browser in order to visit the payment site. This change is believed to be due to Tor proxy services being blocked.
Adding the extra step in the infection process is expected to result in more infections. Many users who would not open a Word attachment may be fooled into opening the PDF.
Businesses should raise the alarm and send out warning emails to staff alerting them to the new campaign and advising them to be wary of PDF files in emails.
The Intercontinental Hotels Group data breach previously announced in February as affecting 12 hotels in the chain has proven to have been far more extensive than was first thought.
Last week the group announced that the breach affected guests that used their credit cards to pay at franchisee hotels across the United States and in Puerto Rico between September 29, 2016 and December 29, 2016.
According to the chain’s website, the Intercontinental Hotels Group data breach potentially affected guests who stayed at its Holiday Inn, Holiday Inn Express, Crowne Plaza, Staybridge Suites, Candlewood Suites, Hotel Indigo, and InterContinental Hotels. The full list of hotels that have potentially been affected by the malware incident has been listed on the IHG website. In total, 1,184 of the group’s hotels have potentially been affected.
The Intercontinental Hotels Group data breach involved malware that had been downloaded onto its systems, which was capable of monitoring payment card systems and exfiltrating payment card data. It does not appear that any other information other than card details and cardholders’ names were stolen by the attackers.
The hotel group does not believe the data breach extended past December 29, 2016, although that cannot be entirely ruled out as it took until February/March for all of the affected hotels to be investigated and for confirmation to be received that the malware had been removed.
Prior to the malware being installed, IHG had started installing the OHG Secure Payment Solution (SPS), which provides point to point encryption to prevent incidents such as this from resulting in the theft of clients’ data. Had the process started sooner, the Intercontinental Hotel Group data breach could have been prevented.
Hotels that had implemented the SPS prior to September 29, 2016 were not affected and those that had implemented the solution between September 29, 2016 and December 29, 2016 stopped the malware from being able to locate and steal credit card data. In those cases, only clients that used their credit cards at affected hotels between September 29, 2016 and when the SPS system was installed were affected.
Intercontinental Hotels Group Data Breach One of Many Affecting the Hospitality Sector
The Intercontinental Hotels Group data breach stands out due to the extent to which the group was affected, with well over 1,100 hotels affected. However, this is far from the only hotel group to have been affected by POS malware. Previous incidents have also been reported by Hard Rock Hotels, Hilton Hotels, Omni Hotels & Resorts and Trump Hotels.
Hotels, in particular hotel chains, are big targets for cybercriminals due to the size of the prize. Many hotel guests choose to pay for their rooms and services on credit cards rather than in cash, and each hotel services many thousands – often tens of thousands – of guests each year.
Globally, IHG hotels service more than 150 million guests every year, which is a tremendous number of credit and debit cards. Such a widespread malware infection would be highly lucrative for the attackers. Credit card numbers may only sell for a couple of dollars a time, but with that number of guests, an attack such as this would be a huge pay day for the attackers.
The Hospitality Sector is a Big Target and Vulnerable to Cyberattacks
While many tactics are used to gain access to POS systems, oftentimes it is weak or default passwords that allow hackers to gain access to hotel computer systems. Stolen credentials are another common way that access is gained. The Verizon’s Data Breach Investigations Report (DBIR) for 2016 shows that in each of the reported breaches affecting the hospitality sector, access to systems was gained by the attackers in less than an hour.
Malware can also be inadvertently downloaded by employees and guests. Poor segregation of the POS system from other parts of the network is commonplace. That makes it easy for hackers to move laterally within the network once a foothold has been gained. Doubling up POS systems as workstations makes it too easy for hackers to gain access to POS systems.
Many hotels also fail to perform adequate risk assessments and do not conduct penetration tests or vulnerability scans. Even malware scans are performed infrequently. Some hotels also fail to implement appropriate security solutions to block access to malware-laden websites.
The Intercontinental Hotels Group data breach could have been prevented, and certainly discovered more quickly. The same is true for many hotel data breaches.
Unless hotels and hotel groups improve their cybersecurity posture and implement appropriate technology, policies and procedures to prevent cyberattacks, data breaches of this nature will continue to occur.
TitanHQ offers a range of products that can prevent hackers from gaining access to computers and POS systems. For further information on how you can protect your hotel or chain against cyberattacks, contact the TitanHQ team today.
Last week, the Bitglass Threats Below the Surface Report was released. The report highlights the extent to which organizations are being attacked by cybercriminals. Far from cyberattacks being a relatively rare occurrence, they are now as certain as death and taxes.
The report revealed that out of the 3,000 IT professionals surveyed for the report, 87% said they had experienced a cyberattack in the past 12 months. Many of those respondents had experienced numerous cyberattacks in the past year, with one company in three experiencing more than five cyberattacks in the last 12 months. To put that figure in perspective and show how the probability of being attacked has increased, two years ago, only half of companies were experiencing cyberattacks on that scale.
IT professionals rated mobile devices as one of the biggest problem areas. When asked to rate security posture, more respondents rated mobile as somewhat or highly vulnerable than any other system. While attacks can come from all angles, the report revealed that many companies are not actively monitoring their systems and devices for potential vulnerabilities. Only 24% monitored SaaS and IaaS apps for vulnerabilities, 36% monitored mobile devices and 60% monitored the network perimeter and laptops/desktops.
In response to the increased number of threats and the frequency of cyberattacks, companies have been forced to increase spending on cybersecurity defenses. The Bitglass Threats Below the Surface Report shows biggest spenders are the retail and technology sectors, with 39% of retail organizations and 36% of technology companies saying they are now spending a large proportion of their budgets on cybersecurity. 52% of respondents said their organization is planning on increasing cybersecurity spending.
Respondents were asked to rate their biggest concerns for the report to get a gauge of the biggest perceived threats. The biggest concern for 37% of respondents is phishing. Phishing attacks are becoming more sophisticated and harder for non-security professionals to identify. A range of social engineering techniques are used to fool end users into opening infected email attachments or clicking on malicious links and revealing their sensitive information. While effective at preventing many phishing attacks, training alone is no longer sufficient. Technological controls are now essential.
Malware is also a major concern along with insider threats, rated as a top concern by 32% and 33% of respondents, with email one of the main methods of malware delivery. Ransomware was also a major concern, although while ransomware attacks can result in significant costs and system downtime, fortunately, many companies have improved their ransomware defenses and have been able to recover without paying a ransom by restoring files from backups.
54% of companies said they had experienced a ransomware attack and were able to recover their data from backups without having to pay a ransom. That said, 33% of companies had no alternative but to pay a ransom to recover locked data, while 13% of companies said they had refused to pay a ransom and had experienced data loss as a result.
Do you have any machines running on unsupported operating systems? Is all of your software up to date with all of the latest patches applied? If you are not patching promptly or are still running outdated, unsupported operating systems or software, you are taking unnecessary risks and are leaving your network open to attack.
Hackers are constantly trawling the Internet looking for vulnerable systems to attack. Even if you are only running Windows XP or Vista on one networked machine, it could allow a hacker to exploit vulnerabilities and gain access to part or all of your network.
An alarming number of businesses are still running outdated software and are not patching promptly. For instance, 7.4% of businesses are still using Windows XP, even though Microsoft stopped issuing patches three years ago.
Hackers are discovering new vulnerabilities in software and operating systems faster than the software manufacturers can address those flaws. Zero-day vulnerabilities are regularly discovered and exploits developed to take advantage of the flaws and gain access to business networks. When a software developer stops issuing updates, the list of potential vulnerabilities that can be exploited grows fast.
Take Windows for example. Each set of updates released by Microsoft every Patch Tuesday contains patches to remediate several critical vulnerabilities that could be exploited to run code or access a system and gain user privileges. While exploits may not currently exist for those flaws at the time the patches are released, that is not the case for long. Hackers can look at the updates and reverse engineer patches to discover the vulnerabilities. Exploits can then be developed to attack unpatched machines.
Take the recent set of updates addressed by Microsoft in its March Patch Tuesday update as an example. Microsoft silently patched a slew of flaws for which exploits had been developed. Four days later, exploit tools from The Equation Group were dumped online by Shadow Brokers. Those tools could be used to exploit the flaws addressed by Microsoft a few days previously.
The exploit tools can be used to attack unpatched machines, but the patches were only issued to address flaws in supported versions of Windows. Many of those exploit tools can be used to attack unsupported Windows versions such as XP and Vista.
One of those tools, called Eternalromance, will likely work on all previous versions of Windows back to Windows XP. EasyPi, Eclipsedwing, Emeraldthread, eraticgopher and esteemaudit have all been confirmed to work on Windows XP.
Those are just the exploit tools recently discovered by The Equation Group. They represent just a small percentage of the exploits that exist for flaws in older, unpatched Windows versions. In addition to exploits for Windows flaws, there are exploits for many software programs.
There will always be zero day exploits that can be used to attack businesses, but running outdated software and unsupported operating systems makes it too easy for hackers.
Businesses of all sizes must therefore ensure that they have good patch management policies covering all software and operating systems and all devices. However, since unsupported operating systems will never be patched, continued use of those products represents a very large and unnecessary risk.
Windows-based systems are far more likely to be infected by viruses and malware; however, Mac users are far from immune to malware infections. A new report from McAfee suggests Mac malware infections increased substantially in 2016. Malware instances rose by a staggering 700% in the space of just one year.
The Threats Report by McAfee Labs shows that its anti-virus solutions detected and prevented 460,000 Mac malware infections in the final quarter of 2016 alone. That is a significant jump from the previous quarter when 150,000 Mac malware infections were detected and blocked – a rise of 247% from Q3 to Q4.
Compared to the number of infections of Windows based systems, the number of mac malware infections is still very low. McAfee detected more than 600 malware samples on Windows devices and 15 million attempted virus attacks on Android devices. At its highest, Mac malware infections were at 1.3% of the level seen on Windows-based devices.
However, the rise in Mac malware attacks should not be ignored. While Mac users are far better protected against malware attacks than Windows users, they should not be complacent. Cybercriminals are now developing more malware to target Mac users and they are no longer content with attacking Windows devices.
McAfee reports that malware developers are increasingly tailoring their malicious software to be capable of attacking multiple platforms. As more consumers and businesses use Macs and other Apple devices, attacks become more profitable. When there is potential for profit, malware developers are quick to take advantage.
The Threats Report indicates much of the new Mac malware is adware, with OSX/Bundlore one of the main malware variants discovered in Q4, 2016. Adware usually comes bundled with legitimate apps, especially apps on non-official stores. Downloading apps from the Mac app store is unlikely to result in infection.
Other forms of Mac malware have also increased in prevalence. As with Windows-based malware, the malware has been developed to steal login credentials and banking details. Remote access Trojans have also increased in number as has Mac ransomware – OSX/Keydnap being a notable example. OSX/Keydnap was bundled with the torrent client BitTorrent and even found its way onto the official download site.
To prevent Mac malware infections, businesses and consumers should be security aware and not take unnecessary risks. Apps should only be downloaded from official stores, security software should be installed, updates to software and apps should be applied promptly and strong, secure passwords should be used.
The cost of a ransomware attack is far higher than the amount demanded by cybercriminals to unlock encrypted files. The final cost of a ransomware attack is likely to be many times the cost of the ransom payment, in fact, the ransom payment – if it is made – could be one of the lower costs that must be covered.
Typically, cybercriminals charge between $400 and $1,000 per infected computer to supply the keys to decrypt data. If one member of staff is fooled into clicking on an infected email attachment or downloading ransomware by another means, fast action by the IT team can contain the infection. However, infections can quickly spread to other networked devices and entire networks can have files encrypted, crippling an organization.
Over the past 12 months, ransomware attacks have increased in number and severity. New ransomware variants are constantly being developed. There are now more than 600 separate ransomware families, each containing many different ransomware variants.
Over the past year there has also been an increase in ransomware-as-a-service (RaaS). RaaS involves developing a customizable ransomware which is rented out to affiliates. Any individual, even someone with scant technical ability, can pay for RaaS and conduct ransomware campaigns. Access to the ransomware may be as little as $50, with the affiliate then given a cut of the profits. There has been no shortage of takers.
Figures from FireEye suggest ransomware attacks increased by 35% in 2016. Figures from the FBI released in March 2016 suggested ransomware had already netted cybercriminals $209 million. Herjavec Group estimated that ransomware profits would top $1 billion in 2016; a considerable rise from the $24 million gathered during the previous calendar year. Figures from Action Fraud indicate ransom payments in the United Kingdom topped £4.5 million last year.
While ransom demands for individual infections can be well below $1,000, all too often ransomware spreads to multiple computers and consequently, the ransom increases considerably. Cybercriminals are also able to gather information about a victim and set ransoms based on ability to pay.
In June 2016, the University of Calgary paid $16,000 to recover its email system. In February last year, Hollywood Presbyterian Medical Center (HPMC) paid a ransom payment of $17,000 to unlock its system. A ransom demand in excess of $28,000 was demanded from MIRCORP following an infection in June 2016. The MUNI metro ransomware attack in San Francisco saw a ransom demand of $73,000 issued!
Figures from Malwarebytes suggest globally, almost 40% of businesses experienced a ransomware attack in the previous year. Ransomware is big business and the costs are considerable.
What is the Cost of a Ransomware Attack?
Ransomware infections can cause considerable financial damage. The cost of a ransomware attack extends far beyond the cost of a ransom payment. The Malwarebytes study suggests more than one third of businesses attacked with ransomware had lost revenue as a result, while 20% were forced to stop business completely.
The FBI and law enforcement agencies strongly advise against paying a ransom as this only encourages further criminal activity. Organizations that are unprepared or are unable to recover data from backups may have little choice but to pay the ransom to recover data essential for business.
However, the true cost of a ransomware attack is far higher than any ransom payment. The HMPC ransomware infection resulted in systems being out of action for 10 days, causing considerable disruption to hospital operations.
System downtime is one of the biggest costs. Even if backup files exist, accessing those files can take time, as can restoring systems and data. Even if a ransom is paid, downtime during recovery is considerable. One study by Intermedia suggests 32% of companies that experienced a ransomware attack suffered system downtime for at least five days.
A study by Imperva on 170 security professionals indicates downtime is the biggest cost of a ransomware attack. 59% of respondents said the inability to access computer systems was the largest cost of a ransomware attack. 29% said the cost of system downtime would be between $5,000 and $20,000 per day, while 27% estimated costs to be in excess of $20,000 per day.
One often forgotten cost of a ransomware attack is notifying affected individuals that their data may have been compromised. Healthcare organizations must also notify individuals if their protected health information (PHI) is encrypted by ransomware under HIPAA Rules.
Major attacks that potentially impact tens of thousands of patients could cost tens of thousands of dollars in mailing and printing costs alone. Credit monitoring and identity theft protection services may also be warranted for all affected individuals.
Many affected individuals may even choose to take their business elsewhere after being notified that their sensitive information may have been accessed by cybercriminals.
Following a ransomware attack, a full system analysis must be conducted to ensure no backdoors have been installed and all traces of malware have been removed. Additional protections then need to be put in place to ensure that future attacks do not occur.
The true cost of a ransomware attack is therefore considerable. The final cost of a ransomware attack could be several hundred thousand dollars or more.
It is therefore essential that businesses of all sizes have appropriate protections in place to prevent ransomware attacks and limit their severity if they do occur.

A new variant of Stampedo ransomware – called Philadelphia ransomware – is being used in targeted attacks on the healthcare sector in the United States. The ransomware variant is being spread using spear phishing emails.
Spear phishing emails have been detected that incorporate the healthcare organization’s logo along with the name of a physician at the organization. The use of a logo and a name adds credibility to the email, increasing the likelihood of the targeted individual clicking the link and downloading the malicious file. Information about organization’s and details of potential targets can easily be found on social media websites such as LinkedIn.
In recent months, cybercriminals have favored email attachments for spreading ransomware and malware, with Word documents containing malicious Word macros one of the most popular methods of ransomware and malware infection. The latest campaign, which was identified by Forcepoint, also uses malicious Word documents. However, rather than sending a malicious Word document as an attachment, the emails contain a link to a website where the Word document is automatically downloaded.
As with email attachments, the document must be opened and macros enabled in order for the ransomware to be downloaded.
Philadelphia Ransomware Attacks Likely to Increase
Philadelphia ransomware attacks are likely to increase thanks to a professional affiliate campaign. Would-be attackers are being recruited using a video that highlights the many features of the ransomware. The video calls Philadelphia ransomware “the most advanced and customizable ransomware ever,” and shows just how easy it is for someone with little technical skill to start their own ransomware campaign.
Would-be cybercriminals are able to rent out the ransomware and use it for their own spamming campaigns, provided they pay the author an initial fee of around $400. The one-off payment, so the authors claim, gives a user lifetime use of the ransomware. Affiliates will then be given a cut of any ransom payments they are able to generate.
Affiliate campaigns such as this – known as ransomware-as-a-service – are becoming increasingly popular. They allow non-technical spammers to jump on the ransomware bandwagon and start generating ransom payments. There is likely to be no shortage of takers.
Fortunately, the ransomware is not as advanced as the promotional video makes out. Furthermore, a decryptor for Philadelphia ransomware has been developed and can be downloaded for free via Softpedia. No ransom needs to be paid, although infection with Philadelphia ransomware can still result in considerable disruption. Healthcare organizations should therefore be on their guard.
Anti-pornography legislation in Alabama could be introduced from January 1, 2018, following the introduction of a new bill last month. House Bill 428 was introduced by Jack Williams (R-Montgomery) to prevent state residents from using Internet-enabled devices to view obscene material.
The anti-pornography legislation classes obscene material as material that would, to an average person, appeal to prurient interest. Pornography, child abuse images and child pornography are included in the definition of obscene content, as is any other material that depicts patently offensive sexual conduct or excretory functions, lacks artistic, political or scientific value, or facilitates or promotes prostitution, sexual cyber-harassment or human trafficking.
If the anti-pornography legislation is passed, the sale of any Internet-enabled device without a web filtering solution in place would be classed as a Class A misdemeanour and would be punishable with a maximum fine of $6,000 per incident and up to one year in jail. However, should such a device be sold to a minor, the offense would increase to a Class C misdemeanor for which the fine would rise to a maximum of $30,000 per incident and a jail term of up to 10 years.
While an Internet filtering solution must be in place at the point of sale, it would not be an offence for the purchaser of the device to remove the filter, provided a request is submitted to the seller in writing, proof that the individual is over 18 years old is supplied and a one-time filter deactivation fee of $20 is paid.
The fees will be collected by the Department of Revenue. 60% of the fees will be directed to the Alabama Crime Victims Compensation Fund, 20% will be directed to grants programs which will in part, be devoted to helping victims of human trafficking, with the remaining 20% of fees deposited in the General State Fund.
It is unclear at this stage how vendors of Internet-enabled devices would ensure that their devices are protected. The legislation describes a filter as a hardware or software solution that can be used to block websites, email, chatrooms, or other Internet-based communications based on category, content or site. The type of filter used will be left to the discretion of the seller.
Since there is a possibility that webpages or websites may be incorrectly categorized, the solution would also require a mechanism that allows websites or content to be blocked or unblocked. The vendor would be required to supply a phone number to a call center to allow requests to block/unblock content to be submitted. Failure to act on those requests in a reasonable time frame would be punishable with a $500 fine for each failure to block an obscene website or webpage.
Alabama is not the only state to propose anti-pornography legislation. Similar bills have also been introduced in New Mexico, North Dakota and South Carolina.
Researchers have identified changes to the Sundown exploit kit. Sundown is now in transition and is being actively developed. It now poses a significant threat.
Exploit kit activity has fallen over the past year as cybercriminals have turned to other methods of infecting end users. Spam email is now favored by many cybercriminals and exploit kit activity has dropped to next to nothing. However, over the past few weeks there has been an increase in exploit kit activity, with the Sundown exploit kit fast becoming a major threat.
Researchers at Cisco Talos report that the Sundown exploit kit has been upgraded and has now matured. While it was once a relatively unsophisticated exploit kit, that is no longer the case. The researchers point out that Sundown is likely to become one of the most widely used exploit kits, taking the place of the larger exploit kits that were used extensively in early 2016.
A number of upgrades have been made to the Sundown exploit kit in recent weeks. The individuals behind the Sundown exploit kit have removed many of the identifiers previously associated with the exploit kit. The exploit kit is now much harder to identify.
The Sundown exploit kit is one of a very small number that have had new exploits added in recent months. Some of the old exploits have also been removed. The actors behind Sundown have also increased the likelihood of infection. In a recent alert, Cisco Talos researchers explain that the exploit kit does not attempt to gain access to a system via a single exploit, instead the Sundown EK uses an extensive arsenal of malware tools to maximize the chance of compromising a system.
While the payload used to be downloaded via the browser, now the exploit kit uses the command line and wscript. A change has also been made to how the malicious payload is downloaded. The payload is now located on a different server to the landing page and exploit kit. The same root domain is used for both, although the subdomains are different.
The actors behind the kit are also purchasing large numbers of established domains, typically domains that are more than 6 months old. Those domains are used for a short time and are then resold. Using older domains allows the attacker to bypass screening controls that blacklist recently registered domains.
The discovery of major updates made to the Sundown EK could indicate there will soon be a major increase in exploit kit attacks. Angler, Neutrino, and Nuclear may have virtually disappeared, but exploit kits still pose a significant threat.
Businesses can protect their endpoints from malware and ransomware infections via exploit kits by using a web filtering solution. A web filtering solution can be configured to carefully control the websites that can be accessed by end users to reduce the risk of infection, and domains known to host exploit kits can be blocked.
For further information on web filtering and protecting end points from malware and ransomware, contact the TitanHQ team today.
Exploit kits have been one of the attack vectors of choice for cybercriminals, although research from Trustwave shows exploit kit activity has been in decline over the past 12 months. Trustwave reports exploit kit activity fell by around 300% over the course of 2016.
Exploit kits are used to probe for vulnerabilities in web browsers and web browser plugins. When a user visits a website hosting an exploit kit, their browser is probed for flaws. If a flaw is found, it is exploited to silently download malware and ransomware.
However, as the middle of the year approached, exploit kit activity started to fall. There are many possible reasons why exploit kit activity has declined. Efforts have increased to make browsers more secure and defenses against exploit kits have certainly been improved.
Adobe Flash vulnerabilities were the most exploited, but last year Adobe started issuing patches faster, limiting the opportunity for the attackers to exploit flaws. The fall in exploit kit activity has also been attributed to the takedown of cybercriminal gangs that extensively used and developed exploit kits. In 2016, the Russian outfit Lurk was broken up and a number of high profile arrests were made. Lurk was the outfit behind the infamous Angler exploit kit. Angler, along with Neutrino, Nuclear and Magnitude were extensively used to download malware and ransomware.
The recently published 2017 IBM X-Force Threat Intelligence Index shows spam email volume increased around the middle of 2016 and there was a marked increase in malicious email attachments. Spam email has now become the attack vector of choice, but that doesn’t mean exploit kits have died. Exploit kits are still being used in attacks, but at a much-reduced level.
Exploit kits are now being used in smaller, more targeted attacks on specific geographical regions, rather than the global attacks using Angler, Nuclear and Magnitude.
Over the past few months, exploit kit activity has started to rise and new exploit kits have been discovered. Late last year, the DNSChanger exploit kit was discovered. While most exploit kits target vulnerabilities in browsers, the DNSChanger exploit kit targets vulnerabilities in routers.
Researchers from Zscaler’s ThreatLabz report there has been an increase in exploit kit activity in the first quarter of 2017. The researchers have noticed a new KaiXin campaign and Neutrino activity has increased. The researchers also detected a new exploit kit called Terror. The Terror exploit kit has been compiled from other exploit kits such as Sundown. The RIG EK continues to be one of the most commonly used kits and has been found to be delivering the ransomware variants Cerber and Locky.
Malicious email attachments may still be the attack vector of choice for spreading ransomware and malware payloads, but the threat from exploit kits is still significant and should not be ignored.

The source code for the NukeBot Trojan has been published online on a source-code management platform. The code for NukeBot – or Nuclear Bot as it is also known – appears to have been released by the author, rather than being leaked.
To date, the NukeBot Trojan has not been detected in the wild, even though it was first seen in December 2016. The NukeBot Trojan was developed by a hacker by the name of Gosya. The modular malware has a dual purpose. In addition to it functioning like a classic virus, it also works like an anti-virus program and is capable of detecting and eradicating other installed malware. The modular design means additional components and functionality can easily be added. When attempting to sell the malware in December last year, the author said further modules would be developed.
The release of the code for the NukeBot Trojan is understood to be an effort by the author to regain trust within the hacking community. IBM says Gosya is a relatively new name in hacking circles, having joined cybercrime forums in late 2016.
While newcomers need to build trust and gain the respect of other hacking community members, Gosya almost immediately listed the malware for sale soon after joining underground communities and failed to follow the usual steps taken by other new members.
Gosya may have developed a new malware from scratch, but he failed to have the malware tested and certified. No test versions of the malware were provided and underground forum members discovered Gosya was using different monikers on different forums in an attempt to sell his creation. Gosya’s actions were treated as suspicious and he was banned from forums where he was trying to sell his malware.
While other hackers may have been extremely dubious, they incorrectly assumed that Gosya was attempting to sell a ripped malware. The NukeBot Trojan was not only real, it was fully functional. There was nothing wrong with the malware, the problem was the actions taken by Gosya while attempting to sell his Trojan.
While many new malware variants are developed using sections of code from other malware – Zeus being one of the most popular – the NukeBot Trojan appears to be entirely new. Back in December, when the malware was first detected and analyzed, researchers from Arbor Networks and IBM X-Force verified that the malware was fully functional and had viable code which did not appear to have been taken from any other malware variant. The malware even included an admin control panel that can be used to control infected computers.
Now that the source code has been released it is likely that Gosya will be accepted back in the forums. The source code will almost certainly be used by other malware developers and real-world NukeBot attacks may now start.
The Recording Industry Association of America (RIAA) wants regulations to be introduced that will force Internet Service Providers to filter pirated content, rather relying on the current system of DCMA takedowns, which the RIAA believes to be ‘antiquated.’ The RIAA claims the current DCMA notice and takedown system is ‘extremely burdensome’ and ‘ineffective’ and that the system invites abuse.
The RIAA and 14 other organizations wrote to the U.S. Copyright Office last week explaining the inadequacies of current DCMA Safe Harbors and suggesting a number of potential solutions to the problem.
Currently, Internet Service Providers are required to take down copyright-infringing content after receiving a DMCA request. The request must be acted on expeditiously and ISPs are legally protected from copyright infringement lawsuits. The legislation has so far protected Internet Service Providers from legal action. Were it not for the legislation, an ISP could potentially be sued every time one of its users uploaded content that violated copyright.
One of the main problems is while the current system protects innocent Internet service providers who have passively, or unwittingly, allowed their services to be used for copyright infringing activities, some entertainment services are protected, even though their businesses are based entirely on copyright infringement, such as the streaming of sports, entertainment and movies.
A number of suggestions have been made such as amending Digital Millennium Copyright Act to include a timeframe for processing DCMA takedowns as well as requiring Internet Service Providers to filter pirated content and use automated systems that identify pirated content and prevent it from being uploaded once the content has been flagged.
The RIAA suggests that when a DCMA request is received requiring specific content to be removed, that content should then be flagged. A system should be put in place that blocks that content from being uploaded in the future on a different webpage or website. Currently, a takedown of content just means the individual or organization can simply upload the content again on another webpage or domain and the process must start over again. The RIAA says the current system is like an endless game of Whac-A-Mole.
The proposals have been criticized as any automated process is likely to result in the removal of web content that is protected under fair use laws and that automated systems could result in the overblocking of website content.
This argument has been countered by the RIAA saying the risk has been exaggerated and that argument is often used by ISPs to avoid implementing content identification technologies. The RIAA argues that current technologies are sufficiently granular to allow them to be calibrated to filter pirated content and protect fair uses.
A flaw in the mobile Safari browser has been exploited by cybercriminals and used to extort money from individuals who have previously used their mobile device to view pornography or other illegal content. The Safari scareware prevents the user from accessing the Internet on their device by loading a series of pop-up messages.
A popup is displayed advising the user that Safari cannot open the requested page. Clicking on OK to close the message triggers another popup warning. Safari is then locked in an endless loop of popup messages that cannot be closed.
A message is displayed in the background claiming the device has been locked because the user has been discovered to have viewed illegal web content. Some users have reported messages containing Interpol banners, which are intended to make the user think the lock has been put on their phone by law enforcement. The only way of unlocking the device, according to the messages, is to pay a fine.
One of the domains used by the attackers is police-pay.com; however, few users would likely be fooled into thinking the browser lock was implemented by a police department as the fine had to be paid in the form of an iTunes gift card.
Other messages threaten the user with police action if payment is not made. The attackers claim they will send the user’s browsing history and downloaded files to the Metropolitan Police if the ransom is not paid.
The Safari scareware campaign was recently uncovered by Lookout, which passed details of the exploit onto Apple last month. Apple has now released an update to its browser which prevents the attack from taking place. Users can protect their devices against attack by updating their device to iOS version 10.3.
Scareware is different from ransomware, although both are used to extort money. In the case of ransomware, access to a device is gained by the attacker and malicious file-encrypting malware is downloaded. That malware then locks users’ files with powerful encryption. If a backup of the encrypted files is not owned, the user faces loss of data if they do not pay the attackers for the key to decrypt their locked files.
Scareware may involve malware, although more commonly – as was the case with this Safari scareware campaign – it involves malicious code on websites. The code is run when a user with a vulnerable browser visits an infected webpage. The idea behind scareware is to scare the end user into paying the ransom demand to unlock their device. In contrast to ransomware, which cannot be unlocked without a decryption key, it is usually possible to unlock scareware-locked browsers with a little computer knowhow. In this case, control of the phone could be regained by clearing the Safari cache of all data.
Another major restaurant POS breach has been detected. This time, Cleveland-based Select Restaurants Inc., has had its POS system breached. Select Restaurants owns many well-known restaurants throughout the United States.
According to Brian Krebs, restaurants known to be affected by the POS malware infection include:
The Rusty Scupper (Baltimore, MD)
Parkers Blue Ash Tavern (Cincinnati, OH)
Parkers’ Restaurant & Bar (Downers Grove, IL)
Winberie’s Restaurant & Bar (Oak Park, IL., Princeton, NJ., Summit, NJ.)
Black Powder Tavern (Valley Forge, PA)
The restaurant POS breach does not appear to have occurred at Select Restaurants, instead it was the chain’s POS vendor that was attacked – Geneva. IL-based 24×7 Hospitality Technology. The attack occurred via a remote access application that the company uses to remotely access, update, and maintain the POS system used by its customers.
After gaining access to the POS system, the attackers installed a form of malware known as PoSeidon. The malware records and exfiltrates credit card data when cards are swiped by restaurant staff when customers pay for their meals. The malware was installed and active for around 3 months from October 2016 to January 2017.
While fraudulent use of customers’ credit card details is often quickly detected by banks and credit card companies, it can be difficult to track those fraudulent card uses back to a specific retailer or restaurant. When major restaurant chains experience POS malware infections it is far easier to detect the source of the fraud. Malware infections at smaller restaurant chains can take much longer to detect. During that time, the credit card details of all of the restaurant’s customers can be stolen.
The remote access system could have been attacked using a variety of methods. If a weak password was used, it may have been guessed or a brute force attack could have occurred. Alternatively, an employee may have revealed a password by responding to a phishing or spear phishing email.
In this case, the malware was installed via the POS system provider, although a restaurant POS breach could just as easily occur. Restaurant chains can do little to prevent attacks on their POS system provider, but they can implement cybersecurity defenses to protect them against direct attacks.
Restaurants are major targets for cybercriminals. Malware can remain undetected for many months during which time many thousands of credit cards can be stolen. The consequences for restaurant chains can be severe. While customers may not experience any losses – their credit card company will usually refund any fraudulent purchases – the effect on a restaurant chain’s reputation can be permanent.
To protect systems from attack, restaurant chains should ensure software solutions are installed to block the most common attack vectors. Software must be kept up to date and patched promptly to prevent vulnerabilities from being exploited and antivirus solutions should be kept up to date and regular scans should be scheduled on all parts of the network.

A House of Lords report on Internet safety for children calls for ISP web filtering controls to be applied as standard.
The UK government is keen for Internet service providers to apply web filtering controls to make it harder for children to access inappropriate website content such as pornography. In 2013, the UK government called on ISPs to implement web filters as standard. Four of the leading ISPs in the UK – Sky, Talk Talk, BT and Virgin Media – responded and have offered filtering controls to their customers.
However, not all ISPs in the United Kingdom provide this level of content control and the House of Lords report suggest that many ISP web filtering controls do not go far enough to ensure children are protected. The report explains that the ‘big four’ ISPs only cover 90% of all Internet users, leaving 10% of users without any form of Internet filtering service.
It is also pointed out in the report that only Sky has opted for a default-on web filter to prevent adult content from being accessed by minors. If new customers want to access adult content they must request that the filter be taken off. The other ISPs have made the service available but do not provide a filtered Internet service that is turned on by default.
The new report calls for ISP web filtering controls to be improved and for ISPs “to implement minimum standards of child-friendly design, filtering, privacy, data collection, and report and response mechanisms for complaints.” The House of Lords report also calls for ISP web filtering controls to be put on all accounts by default, requiring users to specifically request it be turned off if required. Further, the report says the default standard of Internet control should offer the strictest privacy protections for users.
Not everyone agrees with this level of control. The Internet Service Provider Association (ISPA) says that such a move is ‘disproportionate,’ and while the association is committed to keeping children safe when online, mandating ISP web filtering controls is not the way forward. For instance, if an ISP makes it clear that it offers an unfiltered service, that should be permitted. Chairman of the ISPA, James Blessing, believes the best way forward is “a joint approach based on education, raising awareness and technical tools.”
While parents will be well aware of the risks their children face when they go online, the House of Lords report does not believe Internet safety education should be left to parents. addition to making it harder for children to access inappropriate website content, the report calls for mandatory lessons in schools on safe use of the Internet, covering risks, acceptable behavior and online responsibilities.
A health center malware infection has potentially resulted in 2,500 patients’ protected health information (PHI) being sent to unknown individuals over a period of almost a year. Lane Community College health clinic in Eugene, OR, discovered the malware during routine maintenance last month.
Further investigation determined that the malware had been installed on the computer in March 2016. The malware remained active until last month when it was discovered and removed. The malware was identified as Backdoor:Win32/Vawtrak – a Trojan backdoor that enables attackers to steal login information and take full control of an infected PC.
While data access was possible, Lane Community College health clinic uncovered no evidence to suggest patient data had been stolen, although the possibility that PHI was accessed and stolen could not be ruled out. A spokesperson for the clinic said an analysis of 20 other computers used by the clinic uncovered no further malware infections. In this case, the infection was limited as the computer was not connected to other computers on the network.
The only data exposed were those stored on the machine itself. The information potentially exposed included patients’ names, addresses, phone numbers, dates of birth and medical diagnoses.
A health center malware infection can prove costly to resolve. In this case, the infection was limited to one machine, although once access has been gained and malware installed, hackers can often move laterally within a network and spread infections to other machines. Once data have been exfiltrated and there is no further need for access, hackers commonly install ransomware to extort money from their victims.
The exposure or theft of patient data can often lead to lawsuits from patients. While many of those lawsuits ultimately fail, defending a lawsuit can be costly. Healthcare data breaches that result in more than 500 records being exposed are also investigated by the Department of Health and Human Services’ Office for Civil Rights to determine whether the breaches were caused as a result of HIPAA violations. Should HIPAA Rules be found to have been breached, covered entities may have to cover heavy fines.
Health center malware attacks are commonplace due to the value of healthcare data on the black market. Healthcare providers should therefore implement a range of defenses to protect against malware infections.
Malware is commonly inadvertently installed by end users via spam email or redirects to malicious websites. Both of these attack vectors can be blocked with low cost solutions. Backdoor:Win32/Vawtrak – also known as Trojan-PSW.Win32.Tepfer.uipc – is recognized by Kaspersky Lab – one of the dual AV engines used by the SpamTitan spam filtering solution. SpamTitan blocks 100% of known malware and blocks 99.97% of spam emails to keep end users and computers protected.
To protect against Web-borne attacks and to prevent malicious software downloads, WebTitan can be deployed. Web-Titan is a powerful DNS-based web filtering solution that can be used to block a wide range of web-borne threats to keep healthcare networks malware free.
Both solutions are available on a free 30-day trial to allow healthcare providers to experience the benefits first hand before committing to a purchase.

A new form of PoS malware – called MajikPOS malware – has recently been discovered by security researchers at Trend Micro. The new malware has been used in targeted attacks on businesses in the United States, Canada, and Australia.
The researchers first identified MajikPOS malware in late January, by which time the malware had been used in numerous attacks on retailers. Further investigation revealed attacks had been conducted as early as August 2016.
MajikPOS malware has a modular design and has been written in .NET, a common software framework used for PoS malware. The design of MajikPOS malware supports a number of features that can be used to gather information on networks and identify PoS systems and other computers that handle financial data.
The attackers are infecting computers by exploiting weak credentials. Brute force attacks are conducted on open Virtual Network Computing (VNC) and Remote Desktop Protocol (RDP) ports. A variety of techniques are used to install the MajikPOS malware and evade detection, in some causes leveraging RATs that have previously been installed on retailers’ systems. The malware includes a RAM scraping component to identify credit card data and uses an encrypted channel to communicate with its C&C and exfiltrate data undetected.
MajikPOS malware is being used by a well-organized cybercriminal organization and credit card details are being stolen on a grand scale. The stolen information is then sold on darknet ‘dump shops’. The stolen credit card numbers, which the researchers estimate to number at least 23,400, are being sold individually for between $9 and $39. The gang also sells the credit card numbers in batches of 25, 50, or 100. The majority of credit cards belong to individuals in the United States or Canada.
POS Malware Infections Can be Devastating
A number of different attack vectors can be used to install PoS malware. Malware can be installed as a result of employees falling for spear phishing emails. Cybercriminals commonly gain a foothold in retailers’ networks as a result of employees divulging login credentials when they respond to phishing emails.
While exploit kit activity has fallen in recent months, the threat has not disappeared and malvertising campaigns and malicious links sent via emails are still used in targeted attacks on U.S retailers.
Brute force attacks are also common, highlighting how important it is to change default credentials and set strong passwords.
POS malware infections can prove incredibly costly for retailers. Just ask Home Depot. A PoS malware infection has cost the retailer more than $179 million to resolve, with the cost of the security breach continuing to rise. That figure does not include the loss of business as a result of the breach. Consumers have opted to shop elsewhere in their droves following the 2014 PoS malware attack.
This latest threat should serve as a warning for all retailers. Security vulnerabilities can – and are – exploited by cybercriminals. If inadequate protections are put in place to keep consumers’ data secure, it will only be a matter of time before systems are attacked.
There is a new ransomware threat that businesses should be aware of, but PetrWrap ransomware is not exactly anything new. It is actually a form of ransomware that was first discovered in May last year. PetrWarp ransomware is, to all intents and purposes, almost exactly the same as the third incarnation of Petya ransomware. There is one key difference though. PetrWrap ransomware has been hijacked by a criminal gang and its decryption keys have been changed.
The criminal organization behind PetrWrap ransomware have taken Petya ransomware, for which there is no free decryptor, and have exploited a vulnerability that has allowed them to steal it and use it for their own gain. The attackers have simply added an additional module to the ransomware that modifies it on the fly. After all, why bother going to all the trouble of developing your own ransomware variant when a perfectly good one already exists!
Petya ransomware is being offered to spammers and scammers under an affiliate model. The ransomware authors are loaning the ransomware to others and take a percentage of the profits gained from ransoms that are paid. This is a common tactic to increase overall profits, just as retailers pay affiliate marketers to sell their products for a commission. In the case of ransomware-as-a-service, this allows the authors to infect more computers by letting others do the hard work of infecting computers.
Yet the gang behind PetrWrap has chosen not to give up a percentage of the profits. They are keeping all of the ransom payments for themselves. The module modifies and repurposes the malware code meaning even the Petya ransomware authors are unable to decrypt PetrWrap ransomware infections.
Kaspersky Lab research Anton Ivenov says “We are now seeing that threat actors are starting to devour each other and from our perspective, this is a sign of growing competition between ransomware gangs.” He pointed out the significance of this, saying “the more time criminal actors spend on fighting and fooling each other, the less organized they will be, and the less effective their malicious campaigns will be.”
Petya – and PetrWrap ransomware – is not a typical ransomware variant in that no files are encrypted. While Locky, CryptXXX, and Samsa search for a wide range of file types and encrypt them to prevent users from accessing their data, Petya uses a different approach. Petya modifies the master boot record that launches the operating system. The ransomware then encrypts the master file table. This prevents an infected computer from being able to locate files stored on the hard drive and stops the operating system from running. Essentially, the entire computer is taken out of action. The effect however is the same. Users are prevented from accessing their data unless a ransom is paid. Petya and PetrWrap ransomware can spread laterally and infect all endpoint computers and servers on the network. Rapid detection of an infection is therefore critical to limit the harm caused.
When considering how much to invest in cybersecurity defenses, be sure to bear in mind the cost of a retail data breach. Poor security practices and a lack of appropriate cybersecurity defenses can cost a company dearly.
A data breach of the scale of that suffered by Home Depot in 2014 will cost hundreds of millions of dollars to resolve. The home depot data breach was massive. It was the largest retail data breach involving a point of sale system that has been reported to date. Malware had been installed that allowed criminals to steal more than 50 million credit card numbers from home depot customers and around 53 million email addresses.
The attack was made possible due to the use of stolen credentials from one of the retailer’s vendors. Those credentials were used to gain a foothold in the network. Those privileges were subsequently elevated, the Home Depot network was explored, and when access to the POS system was gained, malware was installed to capture credit card details. The malware infection went undetected for five months between April and September 2014.
Last year, Home Depot agreed to pay out $19.5 million to customers that had been affected by the breach. The payout included the costs of providing credit monitoring services to breach victims. Home Depot has also paid out at least $134.5 million to credit card companies and banks, and this week, a further $25 million settlement has been agreed to cover damages suffered by the banks as a result of the breach.
The latest settlement amount will allow banks and credit card companies to file claims for $2 per compromised credit card without having to show evidence of losses suffered. If banks can show losses, they will receive up to 60% of uncompensated losses.
The total cost of the retail data breach stands at around $179 million, although that figure does not include all legal fees that Home Deport will be forced to pay, and neither does it include undisclosed settlements. The final cost of the retail data breach will be considerably higher. It is already creeping closer to the $200 million mark.
Then there is the loss of business as a result of the breach. Following any data breach, customers often take their business elsewhere. Many consumers affected by the breach have chosen to shop elsewhere. There is, after all, not only one DIY retailer in the United States.
A number of studies have been conducted on the fallout from a data breach. One HyTrust study suggests businesses may lose 51% of customers following a breach of sensitive data!
For Home Depot, the cost of a retail data breach has been considerably more than the cost of implementing technologies to monitoring its vendor’s cybersecurity practices, scanning for malware, and implementing security best practices.
The increase in cyberattacks on law firms has prompted the American Bar Association (ABA) to start offering cyber liability insurance for law firms, in addition to its standard insurance policies.
Cyber liability insurance for law firms is becoming as important as travel, medical and dental insurance. Cybercriminals are now targeting law firms with increasing frequency and vigor due to the treasure trove of data they store on clients.
The data can be used for fraud, although the highly sensitive nature of information disclosed to attorneys makes blackmail and extortion an attractive and potentially lucrative option. However, access to sensitive data gives cybercriminals the option of insider trading. Only last year, indictments against three Chinese nationals were unsealed by the Manhattan U.S. attorney’s office showing that more than $4 million in illegal stock trades were performed following the theft of attorney’s emails. The hackers had gained access to email accounts at three Chicago law firms involved in major mergers and acquisitions.
Cybercriminals’ use of stolen data aside, cyberattacks can prove incredibly costly. Following a cyberattack, costs of mitigation can spiral. Law firms must cover the cost of forensic investigations to determine the nature and extent of an attack, and which clients and systems have been impacted. Analyses must identify malware infections and backdoors that may have been installed allowing persistent access to networks and data.
If client data are accessed, law firms must cover the cost of legal defenses and liability protection. Lawsuits will undoubtedly follow any cyberattack. Any breach of sensitive data will almost certainly have an impact on law firms’ reputations, resulting in considerable loss of revenue. Then there are the improvements to cybersecurity defenses to prevent further attacks, the cost of which can be substantial.
For large law firms, cyberattacks can make a significant dent in profits. For small law firms, a cyberattack could prove catastrophic. Given the high costs involved, it is no surprise that cyber liability insurance for law firms is now deemed a necessity.
For the past few years, the ABA has been improving awareness of the cybersecurity risks that must be mitigated by law firms. Awareness has improved as a result and many law firms have invested heavily in technologies to protect against cyberattacks. In 2013, the ABA also petitioned the government to introduce new laws specifically to protect law firms from cyberattacks and the threat of cyber-espionage. Cyber liability insurance for law firms was a natural step for the ABA.
The ABA has developed its new program during the past year to provide affordable coverage from some of the nation’s top insurance carriers. The ABA’s cyber liability insurance for law firms is underwritten by Chubb Limited – The largest publicly traded property and casualty insurer.
Cape Town’s Century City has implemented a free WiFi network for residents, although to make the network more secure and prevent bandwidth abuse, WiFi filtering for cities has been adopted.
The new service – called Let’s Connect – is provided by the telecoms company that operates the fiber-optic broadband network for the Cape Town suburb – Century City Connect – in partnership with ISP Comtel Communications.
The new WiFi network currently comprises 86 WiFi access points within the Cape Town suburb, although there are plans to increase the range of the free WiFi zone to include an extra 100 access points. At present, the WiFi network is supported by a 200 Mbps fiber-optic line which will provide users with 10Mbps speeds for uploads and downloads. Users will be required to register for the service, after which they will be limited to four hours of free WiFi access per day.
Providing a free WiFi network offers residents a host of benefits, but ensuring upload and download speeds are reasonable requires additional technology. If WiFi filtering for cities was not used, there would be considerable potential for the service to be abused by some users. At times of heavy usage, bandwidth will naturally be squeezed, but to limit this as far as is possible, it was necessary for WiFi filtering for cities to be deployed. The web filtering technology place certain limits on user activities.
The WiFi filtering solution used to control internet access is not overly restrictive. Torrent downloads have been blocked, not only because they are used or illegal file sharing, but the downloading of massive files by multiple users has potential to slow Internet speeds across Century City.
In practice, simply blocking torrent sites may not be sufficient to stop bandwidth crushing downloads. It would be possible for users to circumvent the controls. For more comprehensive blocking, the ISP has used DNS-based WiFi filtering, content filtering, and firewalls. Multiple levels of filtering controls makes it much harder for individuals to gain access to torrent sites and upload and download content.
Torrent sites are not the only drain of bandwidth. Software updates likewise suck up bandwidth. Many users have their devices set to update software only when connected to a WiFi network. Connecting to the city WiFi network could see thousands of devices updating software at the same time, further squeezing bandwidth. To reduce the impact, Century City has rate limiting in place. Updates will still be possible, but at a level that will not have a major negative impact on available bandwidth.
As with many locations around the world that use WiFi filtering for cities, Century City will also be using the technology to block adult content. This control works at the domain-level and is based on blacklists. The filters used at Century City also block botnet activity, prevent users from downloading malware and ransomware, and block phishing websites to keep users protected online.
While users will only be permitted four hours of free usage, limits will not be placed on certain categories of website. Educational sites and job websites will be accessible 24/7, even if the 4-hour quota has been used up. A number of other websites will also be whitelisted to ensure constant access is possible.
The project shows how WiFi filtering for cities can be used to ensure the maximum number of users can get the benefits of city-wide free WiFi networks, and how the Internet can be carefully filtered to keep users protected.
The final New York Department of Financial Services cybersecurity rules have now been issued. Covered entities – banks, Insurance companies, and financial service firms operating in the state of New York must now comply with new rules. The financial services cybersecurity rules are the first to be introduced at the state level in the U.S.
The purpose of the cybersecurity rules is to make it harder for cybercriminals to gain access to confidential consumer data. The new rules require companies to adopt a host of cybersecurity measures to keep consumer data confidential and secure.
The financial services cybersecurity rules were first announced last fall. Following the announcement and publication of the draft cybersecurity rules on September 13, 2016, there followed a 45-day comment period. A revised version of the DFS cybersecurity rules was published in late December, which was followed by a further 30-day comment period. The comments received have been considered and now final changes to the cybersecurity rules have been made.
The final financial services cybersecurity rules are effective as of March 1, 2017. Covered entities have up to 6 months to ensure compliance, after which non-compliance could result in a significant financial penalty and other sanctions.
New York state governor Andrew Cuomo announced the release of the final financial services cybersecurity rules saying “New York is the financial capital of the world and it is critical that we do everything in our power to protect consumers and our financial system from the ever-increasing threat of cyber-attacks.”
The new rules should not pose too many problems for the majority of firms in the financial sector, provided that they have already adopted best practices issued by the Financial Industry Regulatory Authority (FINRA) and the Securities and Exchange Commission (SEC). However, where the new cybersecurity rules differ is their specificity. The FINRA and SEC guidelines do not specify the measures that must be adopted, whereas the DFS cybersecurity rules are much more specific about the measures that must be adopted to keep data secure.
The final version of the financial services cybersecurity rules has seen an easing of document retention requirements. In previous versions of the rules, covered entities were required to keep all categories of records for a period of five years. In the final version of the rules, the 5-year retention period only applies to records that are necessary to reconstruct financial transactions to support the normal operations of the company. Records of cybersecurity events that could materially harm the company need only to be kept for three years.
The new rules require the DFS to be notified of a cybersecurity event within 72 hours of it occurring, if the event has a reasonable likelihood of materially harming any part of the normal operations of the covered entity or if the entity has a pre-existing duty to notify another government or regulatory agency.
While the financial services cybersecurity rules are strict, there are many exemptions. Several security experts have suggested the new rules do not go far enough for this very reason.
Many of the exemptions apply to smaller companies. For instance, in order for a company to be a covered entity, the annual turnover must be more than 5 million dollars. Smaller firms employing fewer than 10 individuals are similarly exempt. That effectively means a company with 9 employees does not need to implement as stringent data security measures as a company that employs 10 individuals; however, a line must be drawn somewhere.
There are also exemptions for firms that do not possess or control non-public information. There are further exemptions for charitable organizations and insurance companies that operate in the state of New York, but are not chartered in New York state, and for reinsurers that accept credits or assets from an assuming insurer not authorized in the state. However, further updates of the rules may see some of the exemptions removed.
In all likelihood, 2016 will be forever remembered as The Year of Ransomware, in the same way that 2014 was the year of the healthcare data breach.
2016 Will be Remembered as The Year of Ransomware
Ransomware first appeared in the late 1980’s, although at the time, cybercriminals did not fully embrace it. Instead, they favored viruses, worms, and other forms of malware. That’s not to say that ransomware was not used, only that there were more lucrative ways for cybercriminals to make money.
That all started to change in 2015, when the popularity of cryptomalware was fully realized. By 2016, many actors had got in on the act and the number of ransomware variants started to soar, as did attacks on healthcare providers, educational institutions, government departments, businesses, and even law enforcement agencies. In 2016, it appeared that no one was immune to attack. Many organizations were simply not prepared to deal with the threat.
Early in the year it became clear that healthcare organizations were starting to be targeted for the first time. In February, one of the most notable ransomware attacks of the year occurred. Hollywood Presbyterian Medical Center in Hollywood, CA., was attacked and its computers were taken out of action for well over a week while the medical center grappled with the infection. The decision was taken to pay the ransom demand of $17,000 to obtain the key to decrypt its data.
Not long afterwards, MedStar Health suffered a massive infection involving many of the computers used by the hospital system. In that case, the $19,000 ransom was not paid. Instead, encrypted data were recovered from backups, although the disruption caused was considerable. 10 hospitals and more than 250 outpatient centers had their computers shut down as a result of the infection and many operations and appointments had to be cancelled.
In the first quarter of 2016 alone, the FBI reported that more than $206 million in ransom payments had been made by companies and organizations in the United States. To put that figure in perspective, just $24 million had been paid in the whole of 2015 – That represents a 771% increase in ransom payments and only three months had passed. The year of ransomware had barely even begun!
Biggest Ransomware Threats in 2016
TeslaCrypt was one of the biggest ransomware threats at the start of the year, although the emergence of Locky ransomware in February saw it become an even bigger threat. It soon became the ransomware variant of choice. Locky was used in attacks in 114 countries around the world last year, and cybercriminals continue to tweak it and release new variants. Locky has yet to be cracked by security researchers. Then came Cerber, CryptXXX, Petya (which was defeated in April), and Dogspectus for smartphones, to name just a few.
By the summer, The Guardian newspaper reported that 40% of UK businesses had been attacked with ransomware, although the majority of ransomware attacks were concentrated in the United States. By the autumn, more than 200 ransomware families had been discovered, each containing many variants.
Reports of attacks continued to flood in over the course of the year, with ransomware arguably the biggest cybersecurity threat seen in recent years.
2016 was certainly The Year of Ransomware, but 2017 doesn’t look like it will get any easier for security professionals. In fact, 2017 is likely to be even worse. Some experts have predicted that ransomware revenues will reach $5 billion in 2017.

The ransomware infographic also includes information on the protections that should be put in place to prevent ransomware attacks and the encryption of sensitive data.
Consumers and businesses need to take steps to protect their computers from malware infections, but should there be more malware protection at the ISP level?
Businesses and personal computer users are being infected with malware at an alarming rate, yet those infections often go unnoticed. All too often malware is silently downloaded onto computers as a result of visiting a malicious website.
Websites containing exploit kits probe for vulnerabilities in browsers and plugins. If a vulnerability is discovered it is exploited and malware is downloaded. Malware can also easily be installed as a result of receiving a spam email – if a link is clicked that directs the email recipient to a malicious website or if an infected email attachment is opened.
Cybercriminals have got much better at silently installing malware. The techniques now being used see attackers install malware without triggering any alerts from anti-virus software. In the case of exploit kits, zero-day vulnerabilities are often exploited before anti-virus vendors have discovered the flaws.
While malware infections may not be detected by end users or system administrators, that does not necessarily mean that those infections are not detected. Internet Service Providers – ISPs – are in a good position to identify malware infections from Internet traffic and an increasing number are now scanning for potential malware infections.
ISPs are able to detect computers that are being used for malicious activities such as denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks, and doing so is a relatively easy process.
Malware Protection at the ISP Level
Malware protection at the ISP level involves implementing controls to prevent malware infections and notifying consumers when malicious activity is detected.
ISPs can easily check for potential malicious activity on IP addresses, although blocking those IP addresses is not the answer. While some computers are undoubtedly knowingly used for malicious purposes, in many cases the users of the computers are unaware that their device has been compromised.
ISPs can however alert individuals to a potential malware infection when suspicious activity is identified. Warning emails can be sent to end users to advise them that their computer is potentially infected with malware. Those individuals can be sent a standard email template that contains instructions on how to check for a malware infection.
An increasing number of ISPs are now performing these checks and are notifying their customers of suspicious activity. Many ISPs in Europe provide this cybersecurity checking service and Level 3 Communications is one such ISP that is taking the lead.
The ISP is assessing Internet traffic and is identifying potentially malicious activity associated with certain IP addresses. So far, the ISP has created a database containing around 178 million IP addresses that are likely being used for malicious activity. Many of those IP addresses are static and are part of a botnet. Level3 Communications has estimated that around 60% of those IP addresses have been added to a botnet and 22% of the suspicious IP addresses are believed to be used to send out phishing email campaigns.
The content of Internet traffic is not investigated, although the ISP has been able to determine the IP addresses being used and those which are being sent messages and Internet traffic. While the IP addresses are known, the individuals that use those IP addresses are not. In order to notify individuals of potential infections, Level3 Communications is working with hosting providers. Once the individuals are identified they are contacted and advised of a potential malware infection.
The war on cybercrime requires a collaborative effort between law enforcement, governments, ISPs, and consumers. Only when all of those parties are involved will it be possible to curb cybercrime. Consumers can take steps to prevent infection, as can businesses, but when those measures are bypassed, ISPs can play their part.
If all ISPs were to conduct these checks and send out alerts, malware infections could be tackled and life would be made much harder for cybercriminals.
ISP Web Filtering for WiFi Networks – Protecting Consumers from Malware Infections
Notifying consumers about malware infections is one thing that should be considered, but malware protection at the ISP level should be implemented to prevent consumers and businesses from being infected in the first place.
ISPs can implement web filtering controls to block the accessing of illegal website content such as child pornography. The same technology can also be used to block websites known to contain malware. Broadband providers can implement these controls to protect consumers, and providers of public Internet can use web filtering for WiFi networks.
WiFi filters have already been implemented on the London Underground to prevent users from accessing pornography. Those controls can be extended to block websites known to be malicious. In the UK, Sky WiFi networks use filtering controls to block certain malicious and inappropriate website content from being accessed to better protect consumers. Effective malware protection at the ISP level not only keeps consumers protected, it is also a great selling point in a highly competitive market.
If you are an ISP and are not yet using filtering controls to protect your customers, speak to TitanHQ today and find out more about malware protection at the ISP level and how low-cost web filtering controls can be implemented to keep customers better protected.
In Utah, lawmakers are attempting in make it harder for pornography to be accessed, especially in libraries. A new bill has been introduced that would make it compulsory for library WiFi filtering to be implemented to block patrons from accessing pornography. That bill has now been signed off by a group of Utah senators, bringing the compulsory use of library WiFi filtering closer to being written into the state legislature.
Last year, Sen. Todd Weiler, R-Woods Cross, was heavily involved in a campaign to raise awareness of the problems related to the accessing of hardcore pornography, with the senator claiming the use of pornography had now become “a public health crisis.”
Sen. Weiler, was not alone in his thinking. Many people supported the campaign and agreed that pornography was particularly damaging for minors, that its use threatened marriages and was contributing to the rise in sexual violence.
Library WiFi filtering is a contentious issue. While many libraries across the United States have implemented a WiFi filter to block pornography and other harmful images to protect minors and obtain government grants and discounts, many librarians are opposed to library WiFi filtering.
Libraries are places of learning where individuals can come to gain access to all types of information. The use of Internet filtering in libraries is seen as excessively curbing civil liberties and undermining freedom of speech. Public opinion is similarly divided, although many individuals would not want to catch a glimpse of hardcore pornography on another patron’s computer, and even less so their children.
In Utah, the majority of libraries have already implemented library WiFi filtering software. Weiler says that there are more than 100 public libraries in the state and that the larger libraries are already filtering out pornography. However, he pointed out that there are a dozen or so smaller library branches that have yet to implement Internet filtering on WiFi networks.
In the case of small libraries, there may not be sufficient funds available for WiFi filtering solutions to be purchased, even if by implementing those solutions savings could be made through the eRate program. Sen. Weiler appreciates that the cost of implementing a software solution may be prohibitively expensive for smaller libraries, which is why he is requesting $50,000 from the state budget to be made available to smaller libraries via a grant program. Those grants could then be used to pay for Internet filtering solutions for libraries in the state that have yet to purchase a filtering solution.
Now that the bill has been signed off, it will go before the senate for debate, although there is a high probability that the bill will be written into state law. Support for Sen. Weiler’s anti-pornography campaign last year was strong and many members of the chamber and house of representatives backed Sen. Weiler’s campaign last year. The campaign also received public backing from the governor of Utah.
The email archiving cost can be avoided, but fail to use an email archiving service at your peril. Huge fines await organizations that cannot recover emails promptly.
U.S. businesses are required are required to keep emails for several years. The IRS requires all companies to keep emails for 7 years, the FOIA requires emails to be kept for 3 years, and 7 years again for Healthcare organizations (HIPAA), public companies (Sarbanes Oxley), banking and finance (Gramm-Leach-Bliley Act) and securities firms (SEC).
While large firms are able to absorb the cost of email archiving, many SMBs look at the email archiving cost and try to save money by opting for backups instead. While it is possible to save on the email archiving cost by using backups, the decision not to use an email archiving service could prove to be very costly indeed.
Email backups can serve the same purpose as email archiving in the sense that both can be used to keep old emails. However, while an email backup can help a business protect against data loss, if ever there is a need to recovery backed up emails, companies often encounter problems.
Email backups are fine for recovering entire email accounts (mostly). In the event of a malware or ransomware attack, email backups can be used to recover entire email accounts. However, what happens if only certain emails need to be found – for eDiscovery purposes in the event of a lawsuit for example?
An eDiscovery order may be received that requires all email correspondence sent to a particular client or customer to be retrieved. Such a request may require emails from 100s of employees to be located. Those emails may date back several years. Finding all emails would be an incredibly time consuming process, and it may not actually be possible to recover all correspondence. Backup files cannot easily be searched. They are just data repositories, not a well-managed archive.
An email archive on the other hand is different. Not only can individual emails be easily recovered, the entire archive can be quickly and easily searched. If an eDiscovery request is received, all requested emails can be quickly and easily recovered. The process is likely to take minutes. The recovery of files from a backup could take weeks or even months, assuming that the task is even possible.
Email backups fail surprisingly often. The recent spate of ransomware attacks has highlighted a number of examples of data backups that have been corrupted, leaving organizations little option but to pay the attackers for a key to decrypt locked data. In the case of a ransomware infection, the ransom payment may be hundreds, thousands or even tens of thousands of dollars. However, the failure to produce email correspondence for eDiscovery or a compliance audit can be even higher.
Non-compliance with the Sarbanes-Oxley Act and other industry legislation can see fines of several million dollars issued. Only last year, Scottrade was issued with a fine of $2.6 million by the Financial Industry Regulatory Authority (FINRA). Scottrade had kept records of its emails, but not a complete record. More than 168 million emails had not been retained that should have been present in an archive. As Brad Bennett, Executive Vice President and Chief of Enforcement at FINRA explained when announcing the fine, “Firms must maintain sound supervisory systems and procedures to ensure the integrity, accuracy, and accessibility of electronic books and records.” That includes email correspondence.
The cost of email archiving is not only low compared to the cost of a regulatory fine, email arching is actually inexpensive, especially when using a cloud-based email archiving solution such as ArcTitan. Being cloud-based, emails are securely stored without the need for any additional hardware. Business can rest assured that no email will ever be lost.
In the event of an eDiscovery order, any email can be retrieved almost instantly, regardless of when the email was archived. No specific software is required as emails can be archived from Office 365 and archived messages can be accessed easily using an Outlook plug-in or even directly from the browser. Furthermore, the load on an organization’s email server can be greatly reduced. Reductions of 80% have been seen by a number of TitanHQ’s clients.
To find out more about the full benefits of email archiving and the features of ArcTitan, give the TitanHQ sales team a call today. We think you will be pleasantly surprised at how low the email archiving cost can be.
A recent university cyberattack in the United States resulted in more than 5,000 systems being taken out of action.
The university cyberattack only became apparent after the IT department was flooded with complaints from staff and students that the Internet had slowed to a snail’s pace. By the time that the cyberattack was identified, the attack had spread to multiple systems and devices, resulting in major headaches for the IT department. Attempts were made to bring systems back online but they failed. Not only had IoT devices been compromised, passwords were changed by the attackers. The IT department was locked out and was prevented from gaining access to any of the compromised devices.
The attack involved a range of devices. Even campus vending machines had been loaded with malware and were under the control of the attackers. In total, 5,000 smart devices were compromised in the attack and had been added to an emerging IoT botnet.
An investigation was launched which revealed the extent of the attack. Virtually the entire IoT network had been lost to the attackers. Everything from smart lightbulbs in street lamps to drink-dispensing vending machines had been infected with malware and made part of a botnet.
The IoT devices were making hundreds of DNS lookups, preventing users from performing web searches or visiting websites. In this case, the devices were being used to make seafood-related searches. So many searches that genuine use of the Internet was prevented.
Once the first devices were compromised, the infection spread rapidly. Every IoT device connected to the network was attacked, with the devices brute-forced until the correct username and password combo was found. The devices were then loaded with malware and added to the botnet. The speed at which the IoT devices were compromised and loaded with malware was due to the use of weak passwords and default login credentials. The university, for convenience, had also made the mistake of loading all IoT devices onto one network.
Once the attackers had gained access to an IoT device and loaded their malware, they had full control of the device. To prevent removal of the malware, the attackers changed the password on the device, locking the IT department out.
Once that had occurred, the only way the IT department thought it would be possible to remove the malware and regain control would be to replace every IoT device. All 5,000 of them.
However, before such a drastic measure was taken, the university sought external assistance and was advised to use a packet sniffer to intercept clear-text passwords sent by the attackers to the malware-compromised devices. The university was able to read the new passwords and regain access to its IoT devices. Passwords were then changed on all 5,000 devices and the malware was removed.
A university cyberattack such as this can cause considerable IT headaches, major disruption for staff and students, and involves a not insignificant resolution cost. However, the university cyberattack could have been avoided. Even if an attack was not prevented, its severity could have been greatly reduced.
Had strong passwords been set, the attackers would have found it much harder to infect devices, buying the IT department time and allowing action to be taken to mitigate the attack.
While it is easy to see why all IoT devices were included on a single network, such a move makes it far too easy for cybercriminals to spread malware infections. It is never wise to put all of one’s eggs in the same basket. It is also important to ensure that networks are separated. If access to devices on one network is gained, damage will be limited.
There are many cybersecurity solutions for managed service providers to add to their service stacks and offer to clients. However, the failure to offer a comprehensive range of cybersecurity solutions can prove costly. There is considerable demand for managed services, and the failure to provide them could see clients effectively handed to competitors.
Furthermore, there is now increased competition. Managed service providers have offered preventative cybersecurity solutions to their clients for many years, but competition in this sphere is increasing.
IT companies that have previously relied on fixing computer problems or providing data breach investigative services as their core business have realized there is big money to be made from providing cybersecurity services to prevent problems. An increasing number of IT companies are now capitalizing on high profile data breaches and demand for preventative solutions from SMBs and are now providing these services.
In order to capitalize on the opportunity for sales and to make sure clients do not start looking elsewhere, managed service providers need to make sure that they offer a full suite of cybersecurity solutions. Solutions that will keep their clients protected from the barrage of cybersecurity attacks that are now occurring.
Fortunately, the move away from hardware-based solutions to cloud-based services is making it easier for managed services providers. Cloud-based solutions are not only cheaper for clients, they are easier for MSPs to deliver and manage. While providing solutions that prevent cyberattacks may have been impractical and provided little return for the effort, that is no longer the case.
There are many potential cybersecurity solutions for managed service providers, although one area in particular where MSPs can take advantage is to offer solutions to prevent phishing attacks. Phishing – obtaining sensitive information from employees – is one of the main ways that cybercriminals gain access to networks and sensitive data.
Companies are spending big on network security to prevent direct attacks, yet cybercriminals know all too well that even multi-million-dollar security defenses can be breached. The easiest way to gain network access is to be provided with it by employees.
It is much easier to fool an employee into downloading malware, ransomware, or revealing their email or login credentials that it is to find security vulnerabilities or use brute force tactics. All it takes is for a phishing email to reach the inbox of an employee.
Anti-phishing training companies, which provide security awareness training for employees and teach them how to identify phishing emails, know all too well that training alone is ineffective. Some employees are poor at putting training into practice.
Even if security awareness training is provided, employees will still open email attachments from strangers and click on links sent to them in emails. Furthermore, cybercriminals are getting better at crafting emails to get links clicked and malware-ridden attachments opened.
We have already seen this year (and last tax season) how effective phishing emails can be. At least 145 companies in the United States (that we know about) emailed W-2 Forms of employees to scammers via email last year. This year looks like it will be even worse.
A high percentage of malware infections occur as a result of spam emails with infection either through email attachments (downloaders) or links to malicious sites where malware is silently downloaded. The same is true of many ransomware infections.
Given the high risk of a phishing attack occurring or information-stealing malware and ransomware being installed, organizations are happy to pay for managed solutions that can block phishing emails, prevent malware-infecting emails from being delivered, and stop employees from visiting malicious links.
MSPs can take advantage by providing these services. Since cloud-based solutions are available that offer the required level of protection, adding these solutions to an MSPs service stack is a no brainer. Cloud-based solutions to protect against phishing, malware, and ransomware infections require no hardware, no site visits, and require little management overhead.
TitanHQ can provide cloud-based solutions ideal for inclusion in MSPs service stacks. TitanHQ’s email and web protection solutions – SpamTitan and WebTitan – are effective at blocking a wide range of email and web-borne threats.
SpamTitan blocks over 99.97% of spam email, has a low false positive rate and blocks 100% of known malware. Inboxes are kept spam and malware free, and an anti-phishing component prevents phishing emails from being delivered to end users.
WebTitan offers excellent protection from web-borne threats, protecting employees and networks from drive-by malware and ransomware downloads and blocking links to malicious websites.
Furthermore, these solutions can be run in a public/private cloud, can be provided in white-label format ready for MSP’s branding, have low management overhead and include generous margins for MSPs.
If you are an MSP and are looking to increase the range of cybersecurity services you can offer to clients, give TitanHQ a call today and find out more about the our cybersecurity solutions for managed service providers.
With our cybersecurity solutions for managed service providers, you can improve your cybersecurity portfolio, provide better value to your clients and boost your bottom line.
The past few months have seen an increase in phishing attacks on law firms. Cybercriminals are attacking law firms to gain access to the highly confidential data held by attorneys and solicitors. Healthcare industry attacks are often conducted to obtain sensitive patient data that can be used for identity theft and tax fraud. Phishing attacks on law firms on the other hand are conducted to steal data for insider trading. Data are also stolen to allow cybercriminals to blackmail law firms.
Law firms are threatened with reputation-killing publication of highly sensitive client data if sizeable payments are not made. Since law firms hold secret documents, including potentially damaging information on their clients, it is not only the law firm that can be blackmailed. Clients are also contacted and threatened. The profits that can be made from insider trading are enormous. The data held by law firms is incredibly valuable. It is therefore no surprise that phishing attacks on law firms are increasing. Cybercriminals see law firms as perfect targets.
Last year, more than 50 law firms were targeted by Russian hackers using a spear phishing campaign. The aim of that attack was to gather information that could be used for insider trading. The group, called Oleras, attacked some of the best-known law firms operating in the United States, including Cravath Swaine & Moor LLP and Gotshal and Manges LLP.
However, while those attacks were damaging, they arguably caused less harm than the Panama Papers Breach – The largest law firm data breach of the year. That attack resulted in an astonishing 2.6 Terabytes of data being stolen by the attackers – Documents that revealed highly sensitive banking activities of criminals, politicians, athletes and businessmen and women. More than 214,000 companies had data revealed as a result of that law firm data breach.
While law firms must ensure that firewalls are in place along with a host of other cybersecurity protections to prevent their systems from being hacked, all too often data breaches start with phishing attacks on law firms. A simple email containing a link to a website is sent to attorneys’ and solicitors’ inboxes. The links are clicked and users are fooled into revealing login credentials to networks and email accounts. The credentials are captured and used to gain access to sensitive data.
Website filtering for law firms is now as essential a protection as the use of antivirus software. Antivirus software may be able to detect attempted malware installations – although it is becoming less effective in that regard – although it will do little to prevent phishing attacks.
A web filter protects law firms by preventing users from visiting malicious links in emails. A website filtering solution also prevents end users from downloading malware, or accessing websites known to carry a high risk of infection with ransomware or malware. A web filter also prevents law firm staff from accidentally visiting phishing websites when browsing the Internet. Along with a robust spam filtering solution to prevent phishing emails from being delivered, law firms can make their networks and email accounts much more secure.
Further information on recent phishing attacks on law firms, along with steps that can be taken to prevent security breaches, can be found by clicking the image below. Clicking the image will direct you to a useful phishing infographic on this website.
A law firm phone hacking incident has resulted in an Alexandria, VA attorney being sent a staggering $65,000 phone bill. The attorney’s phone system was hacked and used to make a slew of international phone calls in the middle of the night to numbers in Algeria and Serbia.
In total, 195 phone calls were made through the law firm’s phone system in just 45 minutes. Since the incident occurred in the middle of the night, no one noticed. The small law firm only employs three people, none of whom were in the office at the time.
Attorney David Chamowitz was informed by his service provider via email about the calls and the charges. This law firm phone hacking incident was not a one off. Even though the attorney changed the password on his system, he was attacked again suggesting the hacker had a backdoor into the system. To ensure that future calls were not made, the attorney has had to switch off long distance call capabilities.
The hacker responsible was unlikely to be looking to speak to friends and relatives abroad. This type of scam involves making calls to premium rate international numbers, with the hackers making money from those calls. The charges for the calls can be extortionate, as Chamowitz discovered. Many other small to medium sized businesses have been targeted by hackers and have had to foot the bill for the calls. Phone charges totaling tens of thousands of dollars can easily be racked up.
As was the case with Chamowitz, the attack occurred at a time when it was unlikely to be noticed. Calls are usually made outside of business hours, often in the middle of the night.
Flaws in security systems are exploited to gain access to voicemail systems, although more commonly, hackers take advantage of poor security controls such as default login credentials left active on voicemail systems. Small businesses may implement firewalls and a host of security measures to protect their computers from attack, yet do not realize that voicemail system hacks are also possible.
The default credentials can easily be found online via the search engines or they can be easily guessed. Usernames of ‘admin’ are common and passwords are often set to 1234.
As this law firm phone hacking incident shows, any system that can be accessed externally can be hacked. Whether that is a computer, server, router, IoT device or phone/voicemail system.
To protect against voicemail system hacks it is important to ensure that default credentials are changed and strong passwords are set. A PBX firewall should be employed and calls logs should be monitored. If there is no need for your business to make international or premium rate calls, speak to your service provider and try to block those calls. Also, consider setting the system to not permit outbound calls at certain times (outside of office hours) and disable external access to the phone system/voicemail when the office is closed.
A restaurant malware attack has resulted in the theft of the credit and debit card numbers of more than 355,000 customers, according to Krebs on Security. A breach was suspected to have occurred when credit unions and banks started to notice a flurry of fraudulent purchases. The breach was traced to the fast food restaurant chain Arbys.
While there have been numerous instances of credit card fraud reported in the past few days, the Arbys data breach was first identified in January. Industry partners contacted Arbys regarding a potential breach of credit/debit card numbers. At that point, the incident was only thought to have affected a handful of its restaurants.
The malware infection was soon uncovered and the FBI was notified, although the agency requested that Arby’s did not go public so as not to impede the criminal investigation. However, a statement has recently been released confirming that Arby’s is investigating a breach of its payment card systems.
Upon discovery of the breach, Arby’s retained the services of cybersecurity firm Mandiant to conduct a forensic analysis. The Mandiant investigation is continuing, although rapid action was taken to contain the incident and remove the malware from Arby’s payment card systems. The investigation revealed that the incident only impacted certain corporate-owned stores. None of the franchised stores were infected with malware. Arbys has more than 3,300 stores across the United States, more than 1,000 of which are corporate-owned.
PSCU, an organization serving credit unions, was the first to identify a potential breach after receiving a list of 355,000 stolen credit card/debit card numbers from its member banks. It is currently unclear when the restaurant malware attack first occurred, although the malware is currently thought to have been actively stealing data from October 25, 2016 until January 19, 2017, when the malware was identified and removed.
This is of course not the first restaurant malware attack to have been reported in recent months. The restaurant chain Wendys suffered a similar malware attack last year. That incident also resulted in the theft of hundreds of thousands of payment card details before the malware was discovered and removed. Similar payment card system malware infections were also discovered by Target and Home Depot and resulted in huge numbers of card details being stolen.
Details of how the malware was installed have not been released, although malware is typically installed when employees respond to spear phishing campaigns. Malware is also commonly installed as a result of employees clicking on malicious links contained in spam emails or being redirected to malicious sites by malvertising. In some cases, malware is installed by hackers who take advantage of unaddressed security vulnerabilities.
Once malware has been installed it can be difficult to identify, even when anti-virus and anti-malware solutions are in use. As was the case with the latest restaurant malware attack, data theft was only identified when cybercriminals started using the stolen payment card information to make fraudulent purchases.
Protecting against malware attacks requires multi-layered cybersecurity defenses. Good patch management policies are also essential to ensure that any security vulnerabilities are remediated promptly. Anti-spam and anti-phishing solutions can greatly reduce the volume of messages that make it through to employees’ inboxes, while malicious links and redirects can be blocked with a web filtering solution. A little training also goes a long way. All staff members with computer access should receive anti-phishing training and should be instructed on security best practices.
Regular scans should be performed on all systems to search for malware that may have evaded anti-virus and anti-malware solutions. Since a restaurant malware attack will target payment card systems, those should be frequently scanned for malware. Rapid detection of malware will greatly reduce the damage caused.
If your organization was hit with a malware or ransomware infection last year, the 2016 malware report from Malwarebytes may serve as an unpleasant reminder of 12 months best forgotten. Malware infections rose in 2016 and ransomware infections soared. In the case of the latter, there was an explosion in new variants. Malwarebytes charted a 267% increase in ransomware variants between January 2016 and November 2016. In quarter four alone more than 400 active ransomware variants were cataloged.
The 2016 malware report shows how ransomware has become the revenue-generator of choice for many cybercriminals. It is easy to understand why. Infecting computers is a relatively easy process, ransom payments are made within a matter of days, much of the process is entirely automated, and ransomware-as-a-service means no skill is even required to jump on the bandwagon and send out campaigns.
The 2016 malware report indicates ransomware accounted for 18% of malicious payloads from spam email and ransomware is the payload of choice for exploit kits, accounting for 66% of malicious downloads.
Locky was a major threat for most of the year, but in December there was a massive spike in Cerber ransomware variants, which are now the most populous ransomware family.
The cybersecurity’s company’s 2016 malware report confirms what many security professionals already know all too well. 2016 was a particularly bad year for everyone but the cybercriminals. Unfortunately, the outlook for 2017 does not look any better. In fact, it looks like it will be even worse.
Predictions have been made that will send shivers down many a system administrator’s spine. Ransomware is set to become even more aggressive. Critical infrastructures are likely to be targeted. Healthcare ransomware attacks will increase potentially placing patients’ lives at risk. Educational institutions will be targeted. No organization will be immune to attack.
Fortunately, new ransomware families will be limited in 2017. But that is only because Locky and Cerber are so effective and can easily be tweaked to avoid detection.
Then there are the botnets. The increase in use of IoT devices would not be a problem, were it not for a lack of security. Many insecure devices are coming to market which can all too easily be added to botnets. As we saw in the tail end of the year, these botnets – such as Mirai – are capable of conducting devastating DDoS attacks. Those attacks are only likely to increase in scale and frequency. As Malwarebytes correctly points out, unless manufacturers of IoT devices are better regulated and are forced to improve their security, vast sections of the Internet will come under threat.
So, it looks like all bad news for 2017. All organizations can do is purchase the technology to deal with the threats, plug security holes promptly, train staff to be aware of the threats, and shore up their defenses. The next 12 months could be a rocky ride.
You have secured your servers, you have end point protection, but have you ensured your organization is protected against printer hacking? According to one hacker, as many as 300,000 organizations have left a gaping hole in their security defenses as a result of leaving their printers open to the Internet and failing to even use any form of authentication.
Your Printer Has Been Owned!
The hacker decided to draw attention to the problem, not by publishing details of the flaws, but by attacking around 150,000 companies. The attack was rather benign. The hacker did not attempt to gain access to network resources or install malware. He just sent rogue jobs to the printers.
The printouts said “Your printer has been owned.” The hacker also claimed the printers had been added to ’a flaming botnet’ as a result of the lack of security in place. Some of the messages sent are not appropriate for reproduction. A common message was ‘everyone likes a meme, fix your bull***t.’
The claims were not true, but the hacker did prove a point. Printer hacking is a very real threat and future attacks may be much more malicious in nature. If printers are left open to the Internet with no authentication required, they could be subjected to DoS attacks. Companies would be left unable to print. Printers could also be added to botnets. Those would be best-case scenarios of course. Printer hacking could cause much more serious harm.
Hackers could take advantage of flaws and run arbitrary code. Printers could be used as a launchpad to gain access to corporate networks, sabotage systems, install malware and ransomware, and stealing corporate secrets and sensitive customer and patient data.
Following the printer cyberattack, the ‘victims’ took to social media to report the incidents. Some reported that corporate network printers were affected, others claimed their POS system printers had been owned. In the case of the former, the cyberattack could potentially have resulted in a network compromise. In the case of the latter, credit and debit card-stealing malware could have been installed.
The hacker in question claims he is a UK student with an interest in security research. He says he has access to RCE flaws that would enable him to take control of more than 300,000 printers. In this experiment, he took advantage of the lack of authentication controls on communications port 9100. The attacks involved the RAW protocol, Internet Printing Protocol (IPP) and the Line Printer Daemon (LPD).
Many of the printers susceptible to printer hacking are used by universities and other higher education establishments. In a separate ‘attack’ a different hacker also proved a point about the lack of security controls, the ease of finding computers to attack, and just how easy it was to send rogue output to printers. He chose to send anti-sematic print jobs to printers at universities in the United States for maximum coverage. After the attacks, reports started flooding social media from students at Yale, UC Berkeley, DePaul University and UMass Amherst.
Printer Hacking Mitigation Required
The two hacks come just a few days after security researchers in Germany announced they had discovered vulnerabilities in printer manufacturers by some of the big names in computer hardware, such as Samsung, HP, Dell and Lexmark. More than 20 models of printer were discovered to contain flaws that could be easily exploited. Undoubtedly many more printers are vulnerable.
If printers are left exposed and can be accessed by anyone over the Internet, it will only be a matter of time before a malicious attack occurs. Protecting against printer hacking is therefore essential. To do this, printers should be set up on a virtual private network (VPN) and organizations should make 100% sure that their printers cannot be accessed through public IP addresses. That would require access controls to be applied to routers to whitelist certain IP ranges.
Hotel malware attacks have been hitting the headlines in the past two years as cybercriminals target hotels looking for payment card information. Now, InterContinental Hotels Group Plc has announced that a malware infection has potentially resulted in the theft of customers’ payment card details from 12 of its hotels in the United States. The hotel malware attacks affected guests at InterContinental Hotels as well as Crowne Plaza and Holiday Inn hotels.
The data breach affected the payment systems used by the hotel chain’s restaurants and bars, but did not extend to the front desk system used to process guests.
Malware was installed on the hotels’ servers which searched for and obtained customer track data from credit and debit card transactions. Customers’ card data – including names, card numbers, expiry dates and verification codes – were intercepted and potentially stolen using the malware. The malware was discovered in late December when the hotel chain hired a cybersecurity firm to investigate a potential data breach following an unusual level of fraud affecting the hotel chain’s customers. That investigation revealed malware had been installed as early as August 1, 2016 which remained active until December 15, 2016.
InterContinental has not disclosed whether the malware passed on any payment card information to the attackers nor how many customers had been impacted by the incident, only that servers at 12 of the chain’s hotels had been affected. Investigations into the security breach are continuing and the investigation has now been extended to other hotels owned by InterContinental in the Americas.
Hotels are commonly targeted by cybercriminals seeking payment card information. Last summer, InterContinental’s Kimpton Hotels & Restaurants were attacked with malware and similar incidents were reported last year by Marriot International’s Starwood Hotels as well as the Hyatt, Westin, and Sheraton hotel chains. Hotel malware attacks were reported by the Hilton chain and Trump Hotels in 2015.
Cybercriminals are most interested in POS systems used by hotels. Malware is installed that is capable of capturing payment card information and those data are then transferred to the attackers. All too often, malware is installed and stays active for months before it is detected. During that time, tens of thousands of hotel guests can be impacted and have fraudulent charges applied to their accounts.
While hotel customers are often covered by their card providers’ insurance policy, the fallout from these incidents can be considerable. When guests suffer credit card and debit card fraud as a result of visiting a particular hotel, they may take their business elsewhere.
Malware can be installed by cybercriminals via a number of different attack vectors. Direct attacks take advantage of security flaws in software and hardware. Last year, Cylance’s Sophisticated Penetration Exploitation and Research Team (SPEAR) identified a zero-day vulnerability in ANTLabs InnGate routers, which are used by many of the top hotel chains to provide Internet access for guests. The flaw could be exploited to gain access to guest’s smartphones, laptops, and tablets, or potentially be used to install malware that targets POS systems on hotel servers.
According to SPEAR, the flaw was being actively exploited and 277 hotels had been targeted across 29 countries, including more than 100 hotels in the United States. Eight out of the world’s top ten hotel chains were found to have systems vulnerable to this type of attack. A patch was promptly issued to correct the flaw and hotels were able to plug the security hole.
It may not be possible to prevent attacks that exploit zero-day vulnerabilities; however, there are steps that can be taken to reduce hotel malware attacks. Malware is often downloaded as a result of employees’ or guests’ actions. Malware may be deliberately installed, although all too often downloads occur silently as a result of employees and guests visiting malicious websites.
Blocking access to these websites will protect both the hotel and its guests from web-borne malware and ransomware attacks. If a web filter – such as WebTitan – is installed, all websites known to house malware will be blocked.
If you run a hotel or hotel chain, a web filter is an additional layer of security that should be seriously considered. A web filter will help to reduce the risk of malware and ransomware infections and keep hotel networks safe and secure for all users.
A hotel ransomware attack in Austria hit the headlines in the past couple of days. The cyberattack affected the Romantik Seehotel Jägerwirt. The hotel’s computer system was infiltrated by the attacker who installed ransomware. A range of files were encrypted, which prevented the hotel from being able to check-in new guests and issue new key cards for hotel doors.
Hotel Ransomware Attack Hampers Guest Check-ins
Early reports of the hotel ransomware attack suggested hotel guests were locked out of their rooms or, in some cases, locked in their rooms. The latter is not possible as even when electronic key cards are used, locks can be opened manually from the inside. Guests who had been issued with key cards prior to the attack were also able to use their cards to get in their rooms, according to a statement issued by the hotel’s manager.
However, the cyberattack still caused considerable disruption at the 111-year old hotel. According to local news sources, the attack affected the hotel’s key card system, reservation system, and its cash desk.
Since files were encrypted that were necessary to program new key cards, any guest that had not been checked in before the cyberattack occurred experienced considerable delays. The issue was only resolved when the hotel paid the ransom demand of 1500 Euros – approximately £1,300/$1,600. Systems remained out of action for 24 hours as a result of the attack.
This was not the only attack affecting the hotel. A second attack reportedly occurred, although the hotel was able to thwart that attempt by taking its systems offline. Repeat attacks are unfortunately common. If one ransomware attack results in the payment of a ransom, other attacks may also occur as the attackers attempt to extort even more money from their victim. Backdoors are often installed during initial attacks to enable access to continue after payment has been made.
Not being able to check-in new guests for a period of 24 hours can make a serious dent in profits, not only from guests being forced to seek alternative accommodation, but also from the damage to a hotel’s reputation. Such an attack can keep future guests away.
In this case, in addition to paying the ransom demand, the manager of the Romantik Seehotel Jägerwirt confirmed that the hotel will be going old school in the impending future. Rather than continue to use an electronic key card system, the hotel will revert to using standard keys for hotel room doors. Another hotel ransomware attack would therefore not prevent guests from checking in.
Hotels Must be Prepared for Cybersecurity Incidents
This is not the first hotel ransomware attack to have occurred in 2017 and it certainly will not be the last. Hotels are attractive targets for cybercriminals because hotels cannot afford to have critical systems offline for lengthy periods of time due to the disruption they cause. Cybercriminals know that ransom demands are likely to be paid.
In this case, no lasting harm was caused, although that does not mean future attacks will be limited to reservation systems and cash desk operations. Elevator systems may be targeted or other systems that have potential to compromise the health and safety of guests.
Hotels therefore need to make sure that not only are defenses augmented to prevent ransomware attacks, but a data breach response plan is in place to ensure that in the event of a cybersecurity incident, rapid action can be taken to limit the harm caused.
Malware and phishing attacks on healthcare organizations are all but guaranteed. In fact, they are almost as certain as death and taxes. Healthcare organizations hold huge volumes of data on patients and more types of data than virtually any other industry.
Healthcare providers store personal information and Social Security numbers, which are needed for identity theft and tax fraud. Insurance information that can be used for health insurance fraud; Medicare/Medicaid numbers and health information that can be used for medical fraud. Bank account information and credit card numbers are also often stored. For cybercriminals, breaching a healthcare organization’s defenses means a big payday.
Further, health data does not expire like credit card numbers. Social Security numbers never change. It is therefore no surprise that malware and phishing attacks on healthcare organizations are on the rise.
As if there was not enough incentive to attack healthcare organizations, the healthcare industry has underinvested in cybersecurity defenses, lagging behind other industries when it comes to implementing the latest technologies to thwart cybercriminals. Healthcare networks are also highly complex and difficult to protect. They also contain many outdated software and operating systems. Many healthcare organizations still run medical devices on the unsupported Windows XP OS, which contains many vulnerabilities.
The Health Insurance Portability and Accountability Act (HIPAA) has helped to bring cybersecurity standards up to an acceptable level. HIPAA compliance has made it harder for cybercriminals, although far from impossible. With the healthcare industry, firmly in cybercriminals’ crosshairs, healthcare organizations need to look beyond meeting the minimum standards for data security to avoid a HIPAA fine and ensure that defenses are improved further still.
One of the biggest problems comes from cyberattacks on healthcare employees. Even advanced firewalls can be easily avoided if employees can be fooled into clicking on a malicious link or opening an infected email attachment. Phishing attacks on healthcare organizations are the most common way that cybercriminals gain access to healthcare networks. Most cyberattacks start with a spear phishing email.
In addition to perimeter defenses, it is essential for healthcare organizations to employ technologies to block phishing attacks. Advanced spam filters will prevent the vast majority of phishing emails from being delivered, while web filtering solutions will block phishing attacks on healthcare organizations by preventing malicious links from being clicked and malicious websites from being accessed.
Fortunately, with appropriate defenses in place, cyberattacks can be prevented and the confidentiality, integrity, and availability of ePHI can be preserved.
For further information on the major healthcare cyberattacks of 2016, the key threats to healthcare organizations, and the impact of data breaches, click the image below to view our healthcare hacking infographic.
According to a new report from data breach insurance provider Beazley, US ransomware attacks on enterprises quadrupled in 2016. There is no sign that these attacks will slow, in fact they are likely to continue to increase in 2017. Beazley predicts that US ransomware attacks will double in 2017.
Half of US Ransomware Attacks Affected Healthcare Organizations
The sophisticated nature of the latest ransomware variants, the broad range of vectors used to install malicious code, and poor user awareness of the ransomware threat are making it harder for organizations to prevent the attacks.
For its latest report, Beazley analyzed almost 2,000 data breaches experienced by its clients. That analysis revealed not only that US ransomware attacks had increased, but also malware infections and accidental disclosures of data. While ransomware is clearly a major threat to enterprises, Beazley warned that unintended disclosures of data by employees is actually a far more dangerous threat. Accidental data breaches increased by a third in 2016.
US ransomware attacks and malware incidents increased in the education sector, which registered a 10% rise year on year. 45% of data breaches experienced by educational institutions were the result of hacking or malware and 40% of data breaches suffered by companies in the financial services. However, it was the healthcare industry that experienced the most ransomware attacks. Nearly half of 2016 US ransomware attacks affected healthcare organizations.
The report provides some insight into when organizations are most at risk. US ransomware attacks spiked at the end of financial quarters and also during busy online shopping periods. It is at these times of year when employees most commonly let their guard down. Attackers also step up their efforts at these times. Beazley also points out that ransomware attacks are more likely to occur during IT system freezes.
Ransomware Attacks on Police Departments Have Increased
Even Police departments are not immune to ransomware attacks. Over the past two years there have been numerous ransomware attacks on police departments in the United States. In January, last year, the Midlothian Police Department in Chicago was attacked with ransomware and paid a $500 ransom to regain access to its files.
The Dickson County Sheriff’s Office in Tennessee paid $572 to unlock a ransomware infection last year, and the Tewksbury police department in Massachusetts similarly paid for a key to decrypt its files. In 2015, five police departments in Maine (Lincoln, Wiscasset, Boothbay Harbor, Waldboro and Damariscotta) were attacked with ransomware and in December 2016, the Cockrell Hill Police Department in Texas experienced a ransomware infection. The attack resulted in video evidence dating back to 2009 being encrypted. However, since much of that information was stored in backup files, the Cockrell Hill Police Department avoided paying the ransom.
Defending Against Ransomware
Unfortunately, there is no silver bullet to protect organizations from ransomware attacks. Ransomware defenses should consist of a host of technologies to prevent ransomware from being downloaded or installed, but also to ensure that infections are rapidly detected when they do occur.
Ransomware prevention requires technologies to be employed to block the main attack vectors. Email remains one of the most common mediums used by cybercriminals and hackers. An advanced spam filtering solution should therefore be used to prevent malicious emails from being delivered to end users. However, not all malicious attachments can be blocked. It is therefore essential to not only provide employees with security awareness training, but also to conduct dummy ransomware and phishing exercises to ensure training has been effective.
Many US ransomware attacks in 2016 occurred as a result of employees visiting – or being redirected to – malicious websites containing exploit kits. Drive-by ransomware downloads are possible if browsers and plugins are left unpatched. Organizations should ensure that patch management policies are put in place to ensure that all systems and software are patched promptly when updates are released.
Given the broad range of web-based threats, it is now becoming increasingly important for enterprises to implement a web filtering solution. A web filter can be configured to prevent employees from visiting malicious websites and to block malvertising-related web redirects. Web filters can also be configured to prevent employees from downloading malicious files and engaging in risky online behavior.
The outlook for 2017 may be bleak, but it is possible to prevent ransomware and malware attacks. However, the failure to take adequate preventative steps to mitigate risk is likely to prove costly.
A recently released 2016 data breach report has shown that the number of data breaches reported by businesses has remained fairly constant year on year. 4,149 data breaches were reported between January and December 2016, which is broadly on a par with the figures from 2015.
2015 saw the largest ever healthcare data breach ever reported – The 78.8 million record data breach at Anthem Inc. There were also two other healthcare data breaches in 2015 that resulted in the theft of more than 10 million records. The 11-million record breach at Premera Blue Cross and the 10-million record breach at Excellus BlueCross BlueShield.
2016 saw more data breaches reported by healthcare organizations than in 2015, although the severity of the attacks was nowhere near as bad. More than 27 million healthcare records were exposed in 2016, whereas the total for 2015 was in excess of 113 million.
2016 Data Breach Report Shows Severity of Cyberattacks Has Dramatically Increased
While the severity of healthcare data breaches fell year on year, the 2016 data breach report from Risk Based Security shows an overall increase in the severity of data breaches across all industries. 2016 was a record-breaking year.
In 2013 more than 1 billion records were exposed or stolen – the first time that the 1 billion record milestone had been passed. 2016 saw that previous milestone smashed. More than four times as many records were stolen in 2016 than in 2013. 2016 data breaches exposed an incredible 4.2 billion records.
The RBS 2016 data breach report details 94 data breaches that exposed more than 1 million records. 37 breaches resulted in the exposure of more than 10 million records. The United States was the biggest target, accounting for 47.5% of the data breaches reported over the course of the year.
Healthcare data breaches hit the headlines frequently in 2016 due to the potential impact they had on the victims. However, healthcare industry data breaches only made up 9.2% of the annual total. The business sector was the worst hit, accounting for 51% of breaches in 2016. Government organizations made up 11.7% of the total and education 4.7%.
According to the RBS 2016 data breach report, the top ten data breaches of 2016 exposed an incredible 3 billion records and the average severity score of those breaches was 9.96 out of 10. All but one of those security breaches was caused by hackers. One of the incidents was a web-related breach. Six of the data breaches reported in 2016 ranked in the top ten list of the largest data breaches ever reported.
Six 2016 Security Incidents Ranked in the Top 10 List of Largest Ever Data Breaches
The largest data breach of 2016 – and also the largest data breach ever reported – was the hacking of Yahoo. More than 1 billion user credentials were exposed as a result of that cyberattack. While malware is a major threat to businesses, malware attacks only accounted for 4.5% of data breaches in 2016. Hacking exposed the most records and was the main cause of 2016 data breaches, accounting for 53.3% of incidents and 91.9% of the total number of stolen records.
Many organizations also reported being attacked on multiple occasions. The 2016 data breach report shows that 123 organizations reported multiple data breaches in 2016 and 37% of those organizations reported experiencing three or more data breaches between January and December.
According to RBS, more than 23,700 data breaches have now been tracked. In total, more than 9.2 billion records have been exposed or stolen in those incidents. According to RBS Executive vice president Inga Goddijn, “Any organization that has sensitive data – which is every organization with employees or confidential business information – can be a target.”
Cyberattacks are coming from all angles. Employees are being targeted via email, the volume of malware-laden websites and phishing sites has soared, malvertising is increasing and hackers are exploiting unpatched software vulnerabilities.
It is difficult to predict how bad 2017 will be for cybersecurity breaches, but it is fair to assume that data breaches will continue to occur at a similar level. Organizations need to respond by increasing their cybersecurity defenses to prevent attacks from occurring, but also to prepare for the worst and ensure they are ready to deal with a breach when one occurs. A fast response can limit the damage caused.
The use of web filters in libraries has been in the headlines on many occasions in recent months. There has been much debate over the extent to which libraries should allow patrons to exercise their First Amendment freedoms and whether Internet access should be controlled.
Many libraries in the United States choose not to implement web filters to control the content that can be accessed on their computers, instead they tackle the problem of inappropriate website access by posting acceptable usage guidelines on walls next to computers.
However, patrons of libraries can have very different views of what constitutes acceptable use. Many users of library computers take advantage of the lack of Internet policing and use the computers to view hardcore pornography.
While this is every American’s right under the First Amendment, it can potentially cause distress to other users of libraries. Libraries are visited by people of all ages including children. It is therefore possible that children may accidentally view highly inappropriate material on other users’ screens.
Libraries that apply for government discounts under the e-rate program are required to comply with the Children’s Internet Protection Act (CIPA). The legislation, which went into effect on April 20, 2001, requires schools and libraries to implement controls to restrict Internet access and prevent the viewing of obscene images, child pornography, and other imagery that is harmful to minors. However, it is only mandatory for libraries to comply with CIPA regulations if they choose to take advantage of e-rate discounts. Many libraries do not.
A recent article in DNA Info has highlighted the extent to which library computers are used to access pornography. One patron recently reported an incident that occurred when she visited Harold Washington Library in Chicago to complete forms on a library computer. She claimed that the person on the computer next to her was viewing hardcore pornography and was taking photographs of the screen using his mobile phone camera.
That individual was viewing material of very explicit nature and the screen was in full view of other users of the library. When the woman mentioned what was going on to a security guard, she was told that there was nothing that could be done. The library had chosen to honor patrons First Amendment Rights, even though those rights were in conflict with public decency. A reporter spoke to one librarian who said “Up here in this branch there’s porn 24/7.”
Most libraries in Chicago do not use web filters to limit access to obscene material, although that is not the case in all libraries in the United States. The reverse is true in libraries in Wisconsin for example.
The American Library Association does not recommend the use of web filters in libraries and instead believes the issue of inappropriate website usage should be tackled in other ways, such as to “remind people to behave well in public.”
The debate over First Amendment rights and the blocking of pornography in libraries is likely to continue for many years to come. However, institutions that are commonly frequented by individuals under the age of 18, who are not permitted by law to view pornography, efforts should be made to protect them from harm. If technical measures such as web filters are not used to block pornography in libraries, at the very least libraries should use privacy screens to limit the potential for minors to view other users’ screens.
Do you believe patrons of libraries should be allowed to view any and all website content? Should First Amendment rights extent to the viewing of pornography in libraries?
Credential stuffing attacks on enterprises are soaring according to a recent study conducted by Shape Security. The massive data breaches at the likes of LinkedIn, Yahoo, MySpace have provided cybercriminals with passwords aplenty and those passwords are used in these automated brute force login attempts.
Organizations that have discovered data breaches rapidly force password-resets to prevent criminals from gaining access to users’ accounts; however, stolen passwords can still be incredibly valuable. A study conducted by Microsoft in 2007 suggested that the average computer user has 25 accounts that require the use of a username and password, while Sophos suggests users have an average of 19 accounts.
Password managers can be used to help individuals remember their login credentials, but many people have not signed up for such a service. To remember passwords people just recycle them and use the same password over and over again. Cybercriminals are well aware of that fact and use stolen passwords in credential stuffing attacks on websites and mobile applications.
Shape Security suggests that for many enterprises, 90% of login traffic comes from credential stuffing attacks. Those attacks can be highly effective and since they are automated, they require little effort on the part of the attacker. A batch of passwords is purchased from any number of sellers and resellers on darknet marketplaces. A target site is identified and an automated script is developed to login. The criminals then scale up the assault by renting a botnet. It is then possible to conduct hundreds of thousands of login attempts simultaneously.
Many of the stolen credentials are old, so there is a high probability that passwords will have been changed, but not always. Many people keep the same passwords for years.
The success rate may be low, but the scale of the credential stuffing attacks gives cybercriminals access to hundreds of thousands of accounts.
Shape Security researchers suggest the success rate of these attacks is around 2%. To put this into perspective, if the passwords from the Yahoo data breach were used in credential stuffing attacks, which they almost certainly are, a success rate of 2% would give criminals access to 20 million user accounts.
There is certainly no shortage of passwords to attempt to use to gain access to accounts. According to the report, more than 3 billion username and password combinations were stolen by cybercriminals in 2016 alone. That would potentially give the attackers access to 60 million accounts.
These attacks are not hypothetical. During a 4-month observation period of just one major U.S. retailer in 2016, Shape Security discovered that 15.5 million attempted logins occurred. Even more worrying was that more than 500,000 of the retailer’s customers were using recycled passwords that had previously been stolen from other websites.
Additionally, as a recent report from SplashData has shown, weak passwords continue to be used. The top 25 list of the worst passwords in 2016 still contains very weak passwords such as 123456 and password. These commonly used passwords will also be attempted in brute force attacks. SplashData suggests as many as 10% of Internet users use at least one of the passwords in the top 25 worst password list.
These studies highlight the seriousness of the risk of recycling passwords and send a clear message to organizations: Develop mitigations to prevent the use of stolen credentials and ensure that password policies are developed and enforced.
Internet censorship laws in two U.S. states may be augmented, forcing Internet service providers and device manufacturers to implement technology that blocks obscene material from being viewed on Internet-connected devices.
North Dakota has recently joined South Carolina in proposing stricter Internet censorship laws to restrict state residents’ access to pornography. There is growing support for stricter Internet censorship laws in both states to block pornography and websites that promote prostitution, and it is believed that stricter Internet censorship laws will help reduce human trafficking in the states.
The new Internet censorship laws would not prevent state residents from accessing pornography on their laptops, computers and smartphones, as the technology would only be required on new devices sold in the two states. Any new device purchased would be required to have “digital blocking capability” to prevent obscene material from being accessed. Should the new Internet censorship laws be passed, state residents would be required to pay $20 to have the Internet filter removed.
The proposed law in North Dakota – Bill 1185 – classifies Internet Service Provider’s routers and all laptops, computers, smartphones, and gaming devices that connect to the Internet as “pornographic vending machines” and the proposed law change would treat those devices as such. The bill would also require device manufacturers to block ‘prostitution hubs’ and websites that facilitate human trafficking. If passed, the ban on the sale of non-filtered Internet devices would be effective from August 1, 2017.
Lifting of the block would only be possible if a request to remove the Internet filter was made in writing, the individual’s age was verified in a face to face encounter, and if a $20 fee was paid. Individual wishing to lift the block would also be required to receive a written warning about the dangers of removing the Internet filter.
The fees generated by the state would be directed to help offset the harmful social effects of obscene website content, such as funding the housing, legal and employment costs of victims of child exploitation and human trafficking. Fees would be collected at point of sale.
Device manufacturers would have a duty to maintain their Internet filter to ensure that it continues to remain fully functional, but also to implement policies and procedures to unblock non-obscene website content that has accidentally been blocked by filtering software. A system would also be required to allow requests to be made to block content that has somehow bypassed the Internet filtering controls. Requests submitted would need to be processed in a reasonable time frame. Failure to process the requests promptly would see the company liable to pay a $500 fine per website/webpage.
State Representative Bill Chumley (R‑Spartanburg) introduced similar updates in South Carolina last month, proposing changes to the state’s Human Trafficking Prevention Act. Both states will now subject the proposed bills to review by their respective House Judiciary Committees.
A restaurant WiFi filtering service can help to keep customers safe when they use the Internet by blocking access to websites known to contain malware. A restaurant WiFi filtering service will also ensure that patrons can only view website content that is suitable for families.
WiFi networks are often abused and used by some individuals to view pornography or other material that has no place in a restaurant. If one diner chooses to view such material on a personal device while in a restaurant, other diners may catch glimpses of the screen – That hardly makes for a pleasant dining experience.
However, there is another important reason why a restaurant WiFi filtering service should be used. Diners can be protected from a range of web-borne threats while using free wi-Fi networks, but also the computer systems of the restaurant.
Each year, many restaurants discover that their computers and networks have been infected with malware. Malware infections are often random; however, restaurants are now being targeted by cybercriminals. If a hacker can gain access to a restaurant’s computer network and succeeds in loading malware onto its POS system, every customer who pays for a meal with their debit or credit card could have their credentials sent to the hacker.
Restaurants, especially restaurant chains, are targeted for this very reason. One infected POS system will give a cybercriminal a steady source of credit card numbers. Each year, there are many examples of restaurants that have been attacked in this manner. One of the latest restaurant chains to be attacked was Popeye’s Louisiana Kitchen – A multinational chain of fried chicken and fast food restaurants.
Popeyes recently discovered a cyberattack that resulted in malware being installed on its systems. The attack started on or around May 5, 2016 and continued undiscovered until August 18, 2016. During that time, certain customers who paid for their meals on their credit and debit cards had their card numbers stolen by the malware and passed on to the attackers.
Popeyes only discovered the cyberattack when it received notification from its credit card processor of suspicious activity on customers’ accounts. CCC Restaurant Enterprises, which operates Popeyes, retained a forensic expert to analyze its systems for signs of its systems having been compromised. That analysis revealed a malware infection. The information stealing malware was passing credentials to the attacker and those details were being used to defraud customers. Ten restaurants in the chain were known to have been affected. Those restaurants were located in Georgia, North Carolina, and Texas. The malware infection has now been removed and customers are no longer at risk, although the cyberattack undoubtedly caused reputation damage for the chain.
Malware can be installed via a number of different vectors. Vulnerabilities can be exploited in servers and software. It is therefore essential to ensure that all software is patched and kept up to date. Attacks can occur via email, with malicious links and attachments sent to employees. A spam filter can block those emails and prevent infection. Attacks can also take place over the Internet. The number of malicious websites now produced every day has reached record levels and the threat level is critical.
A restaurant WiFi filtering service will not protect against every possible type of attack but it does offer excellent protection against web-borne threats. A web filtering service can also prevent users from visiting malicious links sent in spam and phishing emails, blocking users’ attempts to click the links. A restaurant WiFi filtering service will also ensure family-friendly Internet access is provided to customers. Something that is increasingly important for parents when choosing a restaurant.

There are advantages and disadvantages of Internet filtering in libraries. Even though there are some potential drawbacks to filtering the Internet, an increasing number of libraries in the United States are now opting to use a web filtering solution.
What are the Advantages and Disadvantages of Internet Filtering in Libraries?
Controlling the types of content that can be accessed via library computers has sparked many debates. The American Library Association (ALA) for instance does not recommend Internet filtering. The problem, according to ALA, is that blocking Internet content in libraries “compromises First Amendment freedoms and the core values of librarianship.”
While it is true that libraries are institutions for learning, restricting access to certain types of website content is particularly important to ensure that children are protected. Unrestricted access to the Internet means minors could all too easily view imagery that could cause harm: Pornography for instance.
The ALA says it is better to tackle the problem of inappropriate Internet access with educational programs rather than restricting access. While the ALA understands that children should be protected from obscene and other potentially harmful website content, teaching children how to use the Internet correctly – and how to search for information – is viewed as a reasonable measure to limit harm.
However, for adults, training is likely to prove less effective. If an adult wishes to access illegal or inappropriate website content, acceptable usage policies and educational programs may not prove effective. Children may also choose to ignore library rules and access inappropriate content.
While many Americans have welcomed the use of Internet filtering in libraries to restrict access to obscene or illegal material, there has been concern raised about how the use of Internet filters could potentially limit access to ideas and valuable information. The main disadvantage of controlling Internet access in libraries is not the restriction of access to certain types of web content that have little to no educational value, but the overblocking of website content.
Some Internet filtering solutions lack granular controls which make it easy for libraries to inadvertently restrict access to valuable material. One example would be blocking of sexual content. Blocking sexual content would prevent pornography from being viewed, but potentially also valuable information on sex education: Sexually transmitted diseases or information on LGBT issues for instance. However, with the right solution, it is possible to carefully control Internet content without accidentally blocking valuable educational material.
Internet Content Filtering Helps Libraries Meet Digital Inclusion Goals
The debate over the advantages and disadvantages of Internet filtering in libraries is likely to go on for some time to come, although for many libraries the decision is now becoming less about First Amendment freedoms and more about money.
Libraries face considerable financial pressures, which can be eased with state and federal grants. The Children’s Internet Protection Act requires libraries to implement an Internet filter to block obscene images, child pornography, and other imagery that could be harmful to minors. Compliance is not mandatory, although it is a prerequisite for obtaining certain grants and discounts under the E-rate program.
Library Services and Technology Act grants are available, although while money can be received, unless an Internet content filter is in place, those funds cannot be used for Internet technology, which can limit the ability of libraries to meet their digital inclusion goals and better serve local communities.
The ALA will not – at the present time at least – recommend the use of Internet filtering in libraries, although the organization does concede that some libraries rely on federal or state funding in order to provide patrons with computers and Internet access.
The message to these institutions is to choose a solution which will “mitigate the negative effects of filtering to the greatest extent possible.”
Libraries can implement an internet content filtering solution to block the minimum level of content in order to comply with state and federal regulations. Policies can be implemented to allow content to be unblocked, if it has been inadvertently blocked by a content filtering solution.
It is then possible to receive funding that will allow them to better serve their communities and meet digital inclusion goals, while ensuring that children – and to a lesser extent adults – are appropriately protected.

Cybersecurity spending in 2016 was increased by 59% of businesses according to PwC. Cybersecurity is now increasingly being viewed as essential for business growth, not just an IT cost.
As more companies digitize their data and take advantage of the many benefits of the cloud, the threat of cyberattacks becomes more severe. The past 12 months have already seen a major increase in successful cyberattacks and organizations around the world have responded by increasing their cybersecurity spending.
The increased threat of phishing attacks, ransomware and malware infections, data theft and sabotage has been a wake up call for many organizations; unfortunately, it is often only when an attack takes place that that wake up call occurs. However, forward-thinking companies are not waiting for attacks, and are increasing spending on cybersecurity and are already reaping the benefits. They experience fewer attacks, client and customer confidence increases, and they gain a significant competitive advantage.
The annual Global State of Information Security Report from Pricewaterhouse Coopers (PwC) shows that companies are realizing the benefits of improving cybersecurity defenses. More than 10,000 individuals from 133 companies took part in the survey that provided data for the report. 59% of respondents said that their company increased cybersecurity spending in 2016. Technical solutions are being implemented, although investment in people has also increased.
Cybercriminals are bypassing complex, multi-layered cybersecurity defences by targeting employees. Organizations have responded by increasing privacy training. 56% of respondents say all employees are now provided with privacy training, and with good reason.
According to the report, 43% of companies have reported phishing attacks in the past 12 months, with this cybersecurity vector the most commonly cited method of attack. The seriousness of the threat was highlighted by anti-phishing training company PhishMe. The company’s Enterprise Phishing Susceptibility and Resiliency Report showed 90% of cyberattacks start with a spear phishing email. Given how effective training can be at reducing the risk from phishing, increasing spending on staff training is money well spent.
The same is true for technical cybersecurity solutions that reduce phishing risk. Two of the most important solutions are antispam and web filtering solutions, with each tackling the problem from a different angle. Antispam solutions are employed to prevent phishing emails from reaching employees’ inboxes, while web filtering solutions are being used to block access to phishing websites. Along with training, companies can effectively neutralize the threat.
Many companies lack the staff and resources to develop their own cybersecurity solutions; however, the range of managed security services now available is helping them to ensure that their networks, data, and systems are adequately protected. According to the PwC report, 62% of companies are now using managed security services to meet their cybersecurity and privacy needs. By using partners to assist with the challenge of securing their systems, organizations are able to use limited resources to better effect and concentrate those resources on other areas critical to business processes.
There has been a change to how organizations are view cybersecurity over the past few years. Rather than seeing cybersecurity as simply a cost that must be absorbed, it is now increasingly viewed important for business growth. According to PwC US and Global Leader of Cybersecurity and Privacy David Burg, “To remain competitive, organizations today must make a budgetary commitment to the integration of cybersecurity with digitization from the outset.” Burg also points out, “The fusion of advanced technologies with cloud architectures can empower organizations to quickly identify and respond to threats, better understand customers and the business ecosystem, and ultimately reduce costs.”
Companies must now deal with a new ransomware threat: 2017 is likely to see a proliferation of doxware attacks.
2016 was the year when cybercriminals fully embraced ransomware and used it to devastating effect on many organizations. As 2016 started, the healthcare industry was heavily targeted. Cybercriminals rightly assumed that the need for healthcare professionals to access patient data would mean ransom payments would likely be paid. That was certainly the case with Hollywood Presbyterian Medical Center. An attack resulted in a ransom of $17,000 being paid to allow the medical center to regain access to patient data and computer systems
Hospitals throughout the United States continued to be attacked, but not only in the United States, Attacks spread to the United Kingdom and Germany. The education sector was also hit heavily. Many schools and universities were attacked and were forced to pay ransoms to obtain keys to unlock their data.
Between April 2015 and March 2016, Kaspersky Lab reported that ransomware infections rose by 17.7%. The figures for April 2016 to March 2017 are likely to show an even bigger rise. Ransomware has rarely been out of the news headlines all year.
Cybercriminals are making stealthier and more sophisticated ransomware variants to avoid detection and cause more widespread disruption. Widespread media coverage, warnings by security companies and law enforcement agencies, and the likely costs of dealing with attacks has led many companies to improve their defenses and develop strategies to recover from infections.
With ransom demands of tens of thousands of dollars – or in some cases hundreds of thousands of dollars – and widespread attacks, the threat can no longer be ignored
One of the best ways of avoiding having to pay a sizeable ransom is to ensure data are backed up. Should ransomware be installed, IT departments can wipe their systems, restore files from backups, and make a quick recovery.
Ransomware is only an effective income generator for cybercriminals if ransoms are paid. If companies can easily recover, and restoring data from backups is cheaper than paying a ransom, cybercriminals will have to look elsewhere to make their money.
However, ransomware is far from dead. Cybercriminasl are changing their tactics. Ransomware is still being used to encrypt data, but an extra incentive is being added to the mix to increase the chance of a ransom being paid.
Doxware: The New Ransomware Threat
Doxware, like ransomware, encrypts data and a ransom demand is issued. However, in addition to encrypting data, information is also stolen. The gangs behind these attacks up the ante by threatening to publish sensitive data if the ransom is not paid.
If access is gained to corporate emails or other electronic conversations, the potential harm that can be caused is considerable. Reputation damage from doxware can be considerable, making payment of a ransom far more preferable to recovering data from a backup. If intellectual property is stolen and published the consequences for a company could be catastrophic.
2016 has already seen extortion attempts by hackers who have infiltrated networks, stolen data, and threatened its release if ransom payments are not made. TheDarkOverlord attacks on healthcare providers are just one example. However, in those attacks data were simply stolen. The combination of data theft with ransomware would be more likely to see ransoms paid. Already we have seen ransomware variants that combine an information stealing component and 2017 is likely to see the problem get far worse.
The proposed crackdown on fake news websites has shone a light on the use of typosquatting and cybersecurity risks for businesses from employees visiting fake news websites.
Over the past few weeks there has been considerable media attention focused on fake news websites and the harm that these fake news stories can cause.
Just as newspapers and news networks can earn big money from being the first to break a new story, there is big money to be made from posting fake news items. The problem is growing and it is now becoming harder to separate fact from fiction. 2016 has seen fake news stories hit the headlines – Both the problem and the republishing of fake news in the mainstream media.
Fake News Websites are a Serious Problem
This year’s U.S. presidential election has seen the Internet awash with propaganda and fake news posts, especially – but not exclusively – about support for Donald Trump and criticism of Hillary Clinton. Fake news sites such as the Denver Guardian (the periodical doesn’t actually exist) posted news about rigging of the election. Genuine news organizations notably picked up on a story about Denzel Washington supporting Trump; however, the original story was taken from a fake news site. Of course, these are just two of many hundreds of thousands of fake news stories published throughout the year.
All too often fake news stories are silly, satirical, or even humorous; however, they have potential to cause considerable harm and influence the public. Potentially, they could change the outcome of an election.
Consumers are now increasingly basing their opinions on fiction rather than fact. Fake news is nothing new of course, but the U.S. presidential election has brought it to the forefront and has highlighted the extent to which it is going on – on a scale never before seen.
Worldwide governments are now taking action to crackdown on the problem. Germany and Indonesia have joined the U.S. in the fight against fake news stories and there have been calls for greater regulation of online content.
Facebook has received considerable criticism for failing to do enough to prevent the proliferation of fake news. While CEO Mark Zuckerberg dismissed the idea that fake news on Facebook was influential in the election – “the idea that fake news on Facebook, which is a very small amount of the content, influenced the election in any way, I think is a pretty crazy idea.” However, last month he confirmed a new initiative to address hoaxes and fake news. Facebook is to make it easier for users to report fake news stories, third-party fact checkers will be enlisted, news websites will be analyzed more closely, and stories will be pushed down the rankings if they are getting fewer shares.
All of the attention on fake news sites has highlighted a tactic that is being used to spread fake news – a tactic that has long been used by cybercriminals to spread malware: Typosquatting.
Typosquatting and Cybersecurity Risks
Typosquatting – otherwise known as URL hijacking – is the use of a popular brand name with authority to fool web surfers into thinking a website is genuine. The fake news scandal brought attention to the tactic after fake news items were posted on spoofed news websites such as usatoday.com (usatoday.com.com) and abcnews (abcnews.com.co).
To the incautious or busy website visitor, the URL may only get a casual glance. The slightly different URL is unlikely to be spotted. This may only result in website visitors viewing fake news, although in many cases it can result in a malware download. Cybercriminals use this tactic to fool web surfers into visiting malicious websites where malware is automatically downloaded.
Typosquatting is also used on phishing websites and for fake retail sites that relieve visitors of their credit card information or other sensitive credentials.
Even fake news sites are a problem in this regard. They often contain third-party adverts – this is one of the ways that fake news stories generate income for the posters. Those adverts are often malicious. The site owners are paid to display the adverts or send visitors to malicious websites. Adverts are also used to direct visitors to fake retail sites – zappoos.com or Amazoon.com for example. Many fake news sites are simply used as phishing farms.
While consumers can be defrauded, businesses should also take note. Since many of these sites are used to either spread malware or direct users to malicious sites where malware is downloaded, fake news sites are a serious cybersecurity risk.
Governments and social media networks may be taking a stand against these malicious sites, but businesses should also take action. All it takes is for one user to visit a malicious site for malware or ransomware to be downloaded.
Fortunately, it is possible to reduce risk with a web filtering solution. Web filtering solutions such as WebTitan can be used to block access to websites known to contain malware. Malicious websites are rapidly added to global blacklists. If a web filtering solution is used, an employee will be prevented from visiting a blacklisted site, which will prevent a malware download.
Malicious adverts can also be blocked and prevented from being displayed. Malicious links on fake news sites can also easily be blocked. Users can also be prevented from visiting websites when clicking on links to the sites in emails or on social media websites.

Anti-phishing solutions for businesses are now an essential element of cybersecurity defenses. The risk from phishing websites has grown considerably in 2016, and 2017 is likely to see the problem become much more severe.
Anti-Phishing Solutions for Businesses Now a Necessity
Cybercriminals are using increasingly sophisticated tactics to infect end users with malware and ‘phish’ for sensitive information such as credit card details, email login credentials, and other sensitive data that can be used for identity theft and fraud. Cybercriminals have changed their tactics to infect more end users and bypass traditional cybersecurity defenses.
In the past it was common for domains to be registered by cybercriminals and only used for phishing or to spread malware. Sooner or later the websites would be reported as malicious in nature, and those domains would be added to global blacklists. As the sites were blocked, the cybercriminals would simply buy another domain and repeat the process. Phishing websites used to remain active for weeks or even months before they ceased to be effective. However, cybersecurity firms are now faster at detecting malicious websites and adding them to blacklists.
Cybercriminals are aware that phishing websites and malicious webpages have a very short shelf life and will only remain effective for a few days before they are blocked. In response, they have changed tactics and are now creating webpages which are only used for very short periods of time.
New webpages are now being created faster and in higher volumes. Those webpages now remain active for less than 24 hours in the majority of cases. Cybercriminals are hijacking legitimate websites with poor security controls or unaddressed vulnerabilities. Malicious URLS are then created and hidden on those domains. Cybercriminals have now all but abandoned malicious websites in favor of single URLs on otherwise benign websites.
The volume of phishing websites has also increased considerably in 2016. Studies now suggest that around 400,000 phishing websites are being detected every month of the year.
Web Filtering Solutions Can Significantly Reduce Risk
There are many anti-phishing solutions for businesses that can be adopted to reduce risk, although one of the most effective tools is an advanced web filter. A web filter can be used to prevent users from visiting malicious websites and webpages that are used to phish for sensitive information or infect end users with malware.
While it was possible for standard web filtering solutions to protect against the risk from phishing by comparing domains against blacklists, it is now essential for each webpage to be checked to determine whether it is malicious. Each URL must also be checked each time it is visited to make sure that it has not been hijacked and used for phishing or to spread malware. For that an advanced web filtering solution is needed, such as WebTitan.
WebTitan checks each webpage that an end user attempts to visit in a fraction of a second, with no noticeable latency – slowing of webpage loading. If a website or webpage is identified as malicious the end user will be prevented from accessing that webpage.
WebTitan allows businesses to further protect their networks by restricting access to certain categories of websites which are commonly used by cybercriminals to spread malware. Since these websites have no legitimate work purpose, they can be easily blocked without any negative impact on the business. In fact, businesses are likely to see significant increases in employee productivity as a result.
Cybercriminals are also increasingly using third party advertising blocks on legitimate websites to display malicious adverts. Those adverts redirect visitors to malicious websites containing exploit kits. Some of those adverts require no user interaction at all – visitors are automatically redirected to websites where drive-by malware downloads occur. WebTitan can be configured to prevent these adverts from being displayed, thus neutralizing the risk.
Cybercriminal activity has been steadily increasing, yet employing an advanced web filtering solution such as WebTitan can help businesses stay one step ahead of cybercriminals and keep their networks malware free.

The increase in cyberattacks and proliferation of web-borne threats has made web filtering for Managed Service Providers one of the most important, and profitable, opportunities for MSPs. However, not all MSPs have started offering a web filtering service to their clients, even though web filtering is now an essential cybersecurity defense
Why is web filtering for Managed Service Providers now so important? Listed below – and in a useful infographic – are some of the reasons why businesses need to control the websites that can be visited by their employees and why web filtering for Managed Service Providers is an important addition to any MSPs service stack.
Cybercriminals Have Switched from Email to the Web to Spread Malware
Email remains one of the most likely routes that malware can be installed. Malicious email volume is growing and in Q3, 2016, Proofpoint discovered 96.8% of malicious attachments were used to download Locky ransomware. Blocking malicious spam email messages is therefore an essential element of any organization’s cybersecurity defense strategy. However, times are a changing. The threat from web-borne attacks has increased significantly in the past few years.
Cybercriminals are well aware that most organizations now use a spam filter to block malicious messages and that they now conduct end user training to warn employees of the risks of opening email attachments or clicking on hyperlinks sent by strangers.
However, far fewer businesses have implemented a solution that blocks web-borne threats. Consequently, cybercriminals have changed their focus from email to the Internet.
The shift to the web means cybercriminals can reach a much bigger target audience and can spread malware and ransomware more effectively. The extent of this paradigm shift is deeply concerning.
Now, more than 80% of malware is web-related and spread via malicious web adverts, hijacked websites, and websites that have been created with the sole purpose of infecting visitors with malware.
As TitanHQ CTO Neil Farrell points out, “the average business user now encounters 3 malicious links per day.” Those links are rarely identified as malicious and the malware downloads that result from visiting malicious websites go undetected.
Web-Borne Threats have Increased Substantially in Recent Years
Cybercriminals use exploit kits – malicious software that probes for vulnerabilities in browsers – on hijacked webpages and purpose designed, malware-laced websites. Zero-day vulnerabilities are frequently identified in web browsers, browser plugins, and extensions and these flaws can be exploited and leveraged to download malware and ransomware. Each time a new flaw is identified, it is rapidly added to a swathe of exploit kits.
Anti-virus software is capable of detecting a high percentage of malware and preventing the malicious software from being installed on computers; however, new forms of malware are being released at an unprecedented rate. A new malware is now released every 4 seconds. Naturally, there is a lag between the release of new malware and the addition of its signature into antivirus software companies’ virus definition lists. Visits to malicious websites all too often result in malware installations that go undetected.
Malicious websites are constantly being created. Google reports that since July 2013, 113,132 new phishing websites have been created and it is businesses that are being targeted. TitanHQ now adds over 60,000 new malware-spreading websites to its blocklists every single day.
Companies that fail to block these web-borne threats face a high risk of their computers and networks being infected with malware. Figures from IDC show that 30% of companies employing more than 500 staff have experienced malware infections as a result of end users surfing the Internet.
New Threats are Constantly Being Developed
Malware is used to log keystrokes to obtain login credentials for further, more sophisticated attacks. Banking credentials are stolen and fraudulent transfers are made. Businesses also have to contend with the current ransomware epidemic. 40% of businesses have now been attacked with ransomware.
Malware and ransomware infections do not just occur via obscure websites that few employees visit. Hugely popular news sites such as the New York Times and the BBC have been discovered to display adverts containing malicious code. Social media websites are also a major risk. 24% of organizations have been infected with malware via Facebook and 7% via LinkedIn/Twitter, according to a recent study by Osterman Research.
These and other serious threats, along with the extent to which infections are occurring, have been summarized in a new infographic that can be accessed by clicking on the image below:

This month, security researchers have discovered cybercriminals are conducting social media ransomware attacks using Facebook Messenger and LinkedIn. Social media posts have long been used by cybercriminals to direct people to malicious websites containing exploit kits that download malware; however, the latest social media ransomware attacks are different.
According to researchers at CheckPoint Security, the social media ransomware attacks take advantage of vulnerabilities in Facebook Messenger. Images are being sent through Facebook Messenger with double extensions. They appear as a jpeg or SVG file, yet they have the ability to download malicious files including ransomware. The files are understood to use a double extension. They appear to be images but are actually hta or js files.
CheckPoint says “The attackers exploit a misconfiguration on the social media infrastructure to deliberately force their victims to download the image file.” The report goes on to say “This results in infection of the users’ device as soon as the end-user clicks on the downloaded file.” No technical details have been released as CheckPoint claim the vulnerability has yet to be fixed by Facebook.
Facebook responded to Blaze’s claim saying the problem was not related to Messenger, but involved bad Chrome extensions. Facebook said the problem had been reported to the appropriate parties.
Ransomware Attacks on the Rise
According to the Kaspersky Security Network, ransomware attacks on SMBs have increased eightfold in the past 12 months. The problem is also getting worse. More than 200 ransomware families have now been discovered by security researchers, and new forms of the malicious file-encrypting software are being released on a daily basis.
Any business that is not prepared for a ransomware attack, and has not implemented security software to protect computers and networks, is at risk of being attacked. A recent survey conducted by Vanson Bourne on behalf of SentinelOne showed that 48% of organizations had been attacked with ransomware in the past 12 months. Those companies had been attacked an average of 6 times.
How to Prevent Social Media Ransomware Attacks
Social media ransomware attacks are a concern for businesses that do not block access to social media platforms in the workplace. It is possible to prevent employees from accessing social media websites using WebTitan, although many businesses prefer to allow employees some time to access the sites. Instead of blocking access to Facebook, businesses can manage risk by blocking Facebook Messenger. With WebTitan, it is possible to block Facebook Messenger without blocking the Facebook website.
If WebTitan is installed, webpages that are known to contain malware or ransomware downloaders will be blocked. When individuals link to these malicious websites in social media posts, employees will be prevented from visiting those sites. If a link is clicked, the filtering controls will prevent the webpage from being accessed.

Many employers are not entirely happy with employees using social media sites in the workplace, and with good reason: There are many risks of social media in business and the costs can be considerable.
Social Media Use Can be a Huge Drain on Productivity
When employees are spending time updating their Facebook accounts or checking Twitter they are not working. All those minutes spent on social media platforms really do add up. Social media site use can be a major drain on productivity.
If every employee in an organisation spends an hour a day on social media sites, the losses are considerable. Unfortunately, many employees spend much more than an hour a day on the sites.
Salary.com reports that around 4% of employees waste more than half of each day on non-work related tasks. For a company employing 1,000 members of staff, that equates to more than 160 hours lost each day, not including the hour or two spent on social media sites by the remaining 96% of the workforce.
Social media site use is not all bad, in fact, the use of the sites can be good for productivity. Employees cannot be expected to work solidly for 8 or more hours each day; at least not 8 highly productive hours. If employees enjoy some ‘Facetime’ every hour or two, it can help them to recharge so they are more productive when they return to their work duties.
The problem for employers is how to control the use of Facebook in the workplace and ensure that social media site use is kept within acceptable limits. Taking 5 minutes off every hour or two is one thing. Taking longer can have a seriously negative impact. Unfortunately, relying on employees to self-moderate their use of social media sites may not be the best way to ensure that Internet use is not abused.
The Cost of Social Media Use Can Be Severe
Productivity losses can have a serious negative impact on profits, but there are far biggest costs to employers from social media site use. In fact, the risks of social media in business are considerable.
The cost from lost productivity can be bad, but nowhere near as bad as the cost of a malware or ransomware infection. Social media sites are commonly used by hackers to infect computers. Just visiting a malicious Facebook or Twitter link can result in a malware or ransomware infection. The cost of resolving those infections can be astronomical. The more time employees spend on non-work related Internet activities, the greater the risk of a malware infection.
Is there a genuine risk? According to PC Magazine, the risks are very real. There is a 40% chance of infection with malicious code within 10 minutes of going online and a 94% chance of encountering malicious code within an hour.
Controlling employees’ use of the Internet can not only result in huge increases in productivity, Internet control can help to reduce the risk of malware and ransomware infections. Further, by limiting the sites that can be accessed by employees, organizations can greatly reduce legal liability.
Fortunately, there is a simple, cost-effective, and reliable solution that allows organisations to effectively manage the risks of social media in business: WebTitan.
Managing the Risks of Social Media in Business
WebTitan is an innovative web filtering solution that allows organizations to accurately enforce Internet usage policies. Employers can block inappropriate content to effectively reduce legal liability, block or limit the use of social media sites to improve productivity, and prevent users from encountering malicious code that could give cybercriminals a foothold in the network.
If you have yet to implement a web filtering solution to control Internet use in the workplace or you are unhappy with the cost or performance of your current web filtering product, contact TitanHQ today and find out more about the difference WebTitan can make to your bottom line.

One of the questions most frequently asked of the WebTitan customer support team is how to block Facebook chat at work without blocking access to Facebook entirely.
Why Block Facebook Chat at Work?
There are many reasons why an organization would want to prevent employees from accessing Facebook. Social media websites can be a drain on productivity. Some employees may spend hours of each day accessing and updating their Facebook account, which is time spent not working.
However, an employee cannot remain productive for a full eight hours each day. By allowing access to Facebook – and other social media sites – employers can actually increase productivity, providing social media site use is kept within acceptable limits.
If employees take short breaks throughout the day and access Facebook for a few minutes every hour, they are likely to be more productive. Morale can also be improved with a little social media site use.
However, there is the question of security to consider and Facebook chat is a particular cause for concern. Many organisations believe Facebook Chat is a security risk. Use of Facebook chat can increase the risk of malware infections. The chat function also lacks the security standards demanded by many organizations and makes it too easy for employees to share sensitive corporate data. Use of Facebook chat is also difficult to police.
How to Block Facebook Chat Without Blocking Facebook Access
With WebTitan Cloud it is easy to block Facebook chat at work without blocking Facebook access entirely. The process takes just a few seconds and is detailed in the video presentation below (and described underneath.)
To block Facebook chat at work, open your WebTitan Cloud administration panel and navigate to “Filtering URL keywords.”
To block Facebook chat you need to add in two blacklisted keywords. Enter in the first keyword:
Then set filter options to ‘find keyword in entire URL’
The second keyword that must be blocked is:
As before, set filter options to ‘find keyword in entire URL’
These two files are used by Facebook chat and if the files are blocked, the Facebook chat will not function, although the Facebook website will still be accessible.
In order for URL keywords to work correctly it is necessary to have the SSL certificate pushed out to the browsers. Further information on how to do this via GPO or manually can be found in the help section on the WebTitan website.
It doesn’t matter which security report you read; one thing is clear. The ransomware problem is becoming worse and the threat greater than ever.
While ransomware attacks in 2015 were few and far between, 2016 has seen an explosion of ransomware variants and record numbers of attacks across all industry sectors. For every ransomware variant that is cracked and decryption software developed, there are plenty more to take its place.
200 Ransomware Families Now Discovered
As if there were not enough ransomware milestones reached this year, there is news of another. The total number of detected ransomware families has now surpassed 200. That’s families, not ransomware variants.
The ransomware families have been catalogued by the ID Ransomware Service; part of the Malware Hunter Team. The current count, which may well be out of date by the time this article is finished, stands at 210.
Not only are new ransomware being developed at an unprecedented rate, the latest variants are even sneakier and have new capabilities to avoid detection. They are also more virulent and capable of encrypting a far wider array of data, and can delete backup files and quickly spread across networks and storage devices.
More people are getting in on the act. Ransomware is being rented out as a service to affiliates who receive a cut of the ransoms they collect. Campaigns can now be run with little to no skill. Unsurprisingly there are plenty of takers.
Massive Campaign Spreading New Locky Ransomware Variant
One of the biggest threats is Locky, a particularly nasty ransomware variant that first appeared in February 2016. Even though Locky has not been cracked, new variants continue to be released at an alarming rate. This week yet another variant has been discovered. The developers and distributers are also using a variant of techniques to evade detection.
Three separate campaigns have been detected this week after a two-week period of relative quiet. The ransomware is now back with a vengeance, with one of the campaigns reportedly involving an incredible 14 million emails on October 24 alone; 6 million of which were sent in a single hour.
There have been some successes in the fight against ransomware. Earlier this year the No More Ransom project was launched. The No More Ransom Project is a joint initiative Europol and the Dutch National Police force, although a number of security firms have now collaborated and have supplied decryptors to unlock files encrypted by several ransomware strains. So far, decryptors have been uploaded to the site that can unlock several ransomware variants: Chimera, Coinvault, Rannoh, Rakhni, Shade, Teslacrypt, and Wildfire.
Ransomware Problem Unlikely to Be Solved Soon
Despite the sterling efforts of security researchers, many of the most widely used ransomware strains have so far proved impossible to crack. The authors are also constantly developing new strains and using new methods to avoid detection. The ransomware problem is not going to be resolved any time soon. In fact, the problem is likely to get a lot worse before it gets better.
Last year, an incredible 113 million healthcare records were exposed or stolen. This year looks like it will be a record-breaking year for breaches if incidents continue at the current rate. The sheer number of healthcare records now available to cybercriminals has had a knock-on effect on the selling price. Whereas it was possible to buy a complete set of health data for $75 to $100 last year, the average price for healthcare records has now fallen to between $20 and $50.
Cybercriminals are unlikely to simply accept a lower price for data. That means more attacks are likely to take place or profits will have to be made up by other means. The glut of stolen data is seeing an increasing number of cybercriminals turn to ransomware.
Are you Prepared for a Ransomware Attack?
With the threat from ransomware increasing, organizations need to prepare for an attack and improve defenses against ransomware. Policies should be developed for a ransomware attack so rapid action can be taken if devices are infected. A fast response to an attack can limit the spread of the infection and reduce the cost of mitigation; which can be considerable.
Defending against ransomware attacks is a challenge. Organizations must defend against malicious websites, malvertising, drive-by downloads, malicious spam emails, and network intrusions. Hackers are not only stealing data. Once a foothold has been gained in a network and data are stolen, ransomware is then deployed.
An appropriate defense strategy includes next generation firewalls, intrusion detection systems, web filtering solutions, spam filters, anti-malware tools, and traditional AV products. It is also essential to provide regular security awareness training to staff to ensure all employees are alert to the threat.
Even with these defenses attacks may still prove successful. Unless a viable backup of data exists, organizations will be left with two options: Accept data loss or pay the ransom. Unfortunately, even the latter does not guarantee data can be recovered. It may not be possible for attackers to supply valid keys to unlock the encryption and there is no guarantee that even if the keys are available that they will be sent through.
Since Windows Shadow copies can be deleted and many ransomware variants will also encrypt backup files on connected storage devices, backup devices should be air-gapped and multiple backups should be performed.
With attacks increasing, there is no time to wait. Now is the time to get prepared.
Most employees are required to agree to use the Internet responsibly and are made to sign an acceptable usage policy as part of their induction before being supplied with a user ID. The policies vary in their content from organization to organization, but typically prohibit individuals from using the Internet to access illegal material, visit websites containing pornography, or engage in online activities that have no work purpose. The policies detail prohibited uses and state the penalties if individuals are discovered to have abused their access rights.
For many businesses, this may be deemed to be sufficient. If policies are breached, there are serious repercussions for the individual. For most employees AUPs alone will be sufficient to stop Internet abuse. However, while a breach of AUPs could result in termination of a work contract or serious disciplinary action against an employee, the consequences for a business can be much more severe.
AUPs can cover employers and prevent legal issues resulting from inappropriate Internet use, but they cannot protect against malware and ransomware infections. The consequences of malware and ransomware infections can be considerable. Data can be lost or corrupted by malware, to confidential information stolen, used for nefarious purposes, or sold on the darknet to criminals. The financial and reputational consequences for a business could be catastrophic.
In the case of ransomware infections, the cost can be considerable. Earlier this year, Hollywood Presbyterian Medical Center experienced a ransomware attack that required a ransom payment of $17,000 to be paid to recover data. The costs of dealing with the infection even after the ransom was paid was considerable, not to mention the disruption to operations while data were locked. Full access to data was not regained for more than a week.
AUPs used to be sufficient to reduce risk – legal and otherwise – but today much more rigorous controls are required to keep networks secure. To manage the risk effectively, it is important to enforce acceptable usage policies with a technological solution.
The most effective way of ensuring AUPs are adhered to is to enforce acceptable usage polices with a web filtering solution. A web filter can be configured to ensure the Internet can only be used for activities that an employer permits. Controls can be applied to ensure that illegal websites are not visited or to block pornography in the workplace, or stricter controls can be applied to severely restrict access. Most importantly given the massive rise in ransomware and malware attacks, controls can be enforced to keep networks secure.
To find out more about the benefits of implementing a web filtering solution, how networks can be secured with WebTItan, and for details of pricing, contact the TitanHQ team today.
Trump Hotels and Management LLC has paid the price for failing to implement robust security controls to secure its POS system from cybercriminals.
The hotel chain, which is headed by Donald Trump and run by three of his children, has been fined $50,000 by the New York Attorney General for a data breach that exposed the credit card details and personal information of over 70,000 guests in 2015.
Banks conducted an investigation following a spate of fraudulent credit card transactions last year, and determined that the common denominator was all of the victims had previously stayed in Trump-owned hotels. In all of the cases, Trump Hotels was the last merchant to process a legitimate card transaction, indicating there had been a breach of credit card details at the hotel chain.
A further investigation revealed that the POS system used by 5 Trump hotels in Chicago, Las Vegas, and New York had been infected with malware. The malware was installed on the credit card processing system in May 2014 and access to the system was gained using legitimate domain administrator credentials. The malware was able to capture the payment card information of guests.
The fine, which was announced by New York Attorney General Eric Schneiderman on Friday, was issued for the failure to adequately secure its systems and for the delay in issuing breach notifications to consumers. Trump Hotels did place a breach notice on the company website, but it took 4 months for that notice to be uploaded – a breach of state laws in New York.
Schneiderman explained “It is vital in this digital age that companies take all precautions to ensure that consumer information is protected, and that if a data breach occurs, it is reported promptly to our office, in accordance with state law.”
A spokesperson for Trump Hotels explained that the hotel industry is under attack by cybercriminals looking to gain access to guests’ credit card details. “Unfortunately, cyber criminals seeking consumer data have recently infiltrated the systems of many organizations including almost every major hotel company.”
Other notable hospitality industry breaches include the cyberattack on Hyatt hotels and Starwood Hotels & Resorts Worldwide. The Hyatt breach affected 250 hotels, while the Starwood breach resulted in the POS systems of 54 hotels being loaded with malware.
Cyberattacks are to be expected; however, security controls at Trump Hotels appear to be insufficient. A second credit card system data breach was discovered to have affected the hotel chain in March this year. Investigators discovered malware had been installed on 39 computer systems used at various locations.
In addition to the $50,000 fine, Trump Hotels has agreed to adopt a corrective action plan which requires additional security controls to be installed to prevent future data breaches.
It may not be possible to prevent all cyberattacks but, with the hospitality industry coming under attack, it is essential that security controls are implemented that prevent the installation of malware. Keyloggers and other information stealing malware are usually delivered via spam email or are unwittingly downloaded from malicious websites.
In order to prevent infections via email, hotel chains can implement a robust spam filter. Web-borne infections can be prevented using a powerful web filtering solution to block malware downloads.
Although many businesses use configured DNS filters to prevent cyberattacks, UK ISPs tend to blanket-block complete categories of websites to limit access to those most likely to be harboring malware. This hit-and-miss approach to online security often blocks genuine websites, or exposes consumers who opt out of DNS filtering to every type of online threat.
However, plans have now been announced that will see the UK´s spy agency – GCHQ – partner up with leading ISPs in the UK in order to develop a more finely-tuned approach to consumer security. Effectively GCHQ will advise the ISPs on how to configure their DNS filters to prevent cyberattacks on consumers based on individual sites known to harbor malware.
By preventing consumers from accessing “bad addresses” that appear to be legitimate domains, GCHQ hopes to reduce the number of malware and phishing attacks launched on the UK public each year. The organization is reported to routinely use DNS filtering to filter out some parts of the internet that the government asks to be banned, and this new initiative is an extension of its existing service.
The plans were announced by Ciaran Martin – head of GCHQ and the recently formed National Cyber Security Centre (NCSC) – at the Billington Cyber-Security Summit. Martin told Summit attendees, “We’re exploring a flagship project on scaling up DNS filtering: what better way of providing automated defenses at scale than by the major private providers effectively blocking their customers from coming into contact with known malware and bad addresses?”
A few years ago, former UK Prime Minister David Cameron attempted to introduce legislation that would require ISPs to block pornography. While legislation was not passed, ISPs entered into a voluntary agreement to block pornography by default. Since 2013, all new customers have been prevented from accessing online pornography by their ISPs unless they choose to opt out and lift the DNS filter. Under this voluntary arrangement, UK citizens are protected from inappropriate content, yet their civil liberties are not violated.
There would likely be considerable backlash if the government was to introduce legislation to block the accessing of certain websites, even if those sites were known to contain threats such as malware or ransomware. Martin is well aware of the potential problems that could arise. He told Summit attendees, “The government does not own or operate the Internet,” explaining that any move to use DNS filters to prevent cyberattacks would need to come from the private sector.
Martin explained that, as with ISPs blocking pornography, consumers would be given a choice to opt out of using DNS filters to prevent cyberattacks. He said “addressing privacy concerns and citizen choice is hardwired into our program.”
The plan to use DNS filters to prevent cyberattacks on consumers and UK businesses has been applauded. “The Great Firewall of Britain” will help to protect consumers from cybercriminal activity and keep electronic devices free from malware and ransomware.
There are currently millions of malicious websites that have been set up with the sole purpose of spreading malware such as banking Trojans, ransomware, spyware, or to commit online fraud. Data from the Information Commissioner’s Office (ICO) shows the number of reported online security incidents has doubled in the past year and cyber-infection rates are growing at an exponential level around the globe.
The use of DNS filters to prevent cyberattacks should go some way towards preventing consumers from inadvertently downloading malware or falling victim to a phishing campaign. However, while this is a step in the right direction, when the plan is implemented it will not spell an end to malware and ransomware attacks.
ISP DNS filters can only block websites that are known to be malicious or have been discovered to host exploit kits or malware. Cybercriminals are constantly changing tactics and are using ever more sophisticated methods of attacking individuals, businesses, and governments. The use of ISP DNS filters to prevent cyberattacks will help to deal with low level attacks, but organizations should not rely on their ISPs to block online threats.
It will still be essential for organizations to carefully control the website content that can be accessed by their employees, and to do that they will need their own web filtering solution.
From September 5, 2016, all schools have a duty to conduct a risk assessment and, where appropriate, implement a web filtering solution to prevent children from being exposed to illegal or harmful online material.
The “guidance” from the Department for Education is mandatory and educational institutions have to comply with the requirements for web filtering in schools, unless it can be shown they are not necessary in the circumstances, or that safeguards providing adequate protection already exist.
Key Issues Covered by the Guidance
The requirements for web filtering in schools form one of three risk categories being addressed by the guidance – the other two being the prevention of harmful online interaction, and online conduct that increases the likelihood of harm.
The Department for Education makes it clear that the guidance refers not only to school computer networks, but also access to mobile technology, and stipulates that policies should be introduced regarding mobile usage on school premises.
It is also a requirement that teaching staff undergo safeguarding training to monitor use of the Internet, so that they can effectively identify children at risk and intervene or escalate where appropriate. Children should also be educated about online safety.
What are the Requirements for Web Filtering in Schools?
While the guidance outlines the requirements for web filtering in schools, it falls short of detailing specific types of website content that should be blocked. Instead it defers to the recommendations made by the UK Safer Internet Centre (UKSIC).
The UKSIC offers guides for appropriate filtering and appropriate monitoring with the caveat that what constitutes inappropriate website content for one age group, may not necessarily apply to all age groups.
It suggests any web filtering solution that is implemented should have reporting mechanisms to provide historical information on the websites visited by users, and the ability to report inappropriate content for access or blocking.
While not an exhaustive list of all types of inappropriate website content, the UKSIC recommends schools and other educational establishments ensure the following categories are blocked by their chosen web filtering solution:
Websites that promote discrimination on the grounds of age, sex, race, and religion.
Websites displaying or promoting the use of narcotics and/or substance abuse.
Websites promoting acts of terrorism or terrorist ideologies, intolerance, or violence.
Websites or tools that enable anonymous browsing of the Internet.
Sites hosting malicious content.
Webpages promoting hacking or the compromising of computer systems.
Webpages containing pornographic images or displaying sexual acts.
Websites promoting or enabling copyright violations or Internet piracy.
Sites displaying or promoting acts of violence with intent to harm, maim, or kill.
Sites promoting self-harm or displaying acts of self-harm, including eating disorders and suicide.
Features of Web Filtering Solutions for Schools
In addition to blocking categories of web content, a suitable web filtering solution for schools should include the ability to:
Identify individual users, the sites visited and the searches performed.
Make changes to filtering parameters at school level as appropriate
Block access to restricted content from mobile devices
Provide multi-lingual filtering support.
Generate reports allowing administrators to view accessed content.
Filter content without the need to download software onto devices.
It is inevitable that some legitimate web pages may be blocked by a web filtering solution. It is therefore important that a system is established that enables users to report when access is blocked to legitimate web pages so that the web pages can be added to a safe list or whitelist.
Web Filtering for Schools No Substitute for Supervision
The UKSIC points out that even the most robust Internet content filtering solutions are not infallible. It is not possible for any solution to be 100% effective, 100% of the time. The UKSIC recommends the requirements for web filtering in schools are supported with “good teaching and learning practice and effective supervision.”
While the blocking of Internet content is important to prevent children from coming to harm, schools should take care not to overblock website content. The UKSIC advises schools, colleges, and other educational establishments to take care web filtering does not unreasonably restrict access to valuable website content.
Are you taking steps to prevent drive-by malware downloads? Have you implemented controls to reduce your attack surface and prevent your employees from inadvertently downloading malware onto your network?
Malvertising – A Major Security Risk that Should be Managed
Malvertising is the term used for the practice of displaying malicious adverts to website visitors. The malicious adverts are displayed via third party advertising networks which are present on a wide range of legitimate websites. Malicious adverts have been displayed to visitors to many of the top 500 global websites.
The New York Times website was discovered to be displaying malvertising via a third party ad networks. Those adverts redirected visitors to websites where ransomware was downloaded. The UK’s BBC website was similarly discovered to be displaying malicious adverts that resulted in ransomware downloads.
Other high profile sites found to be displaying malvertising include AOL, the NFL website, Realtor, theweathernetwork, newsweek, infolinks, answers.com, and thehill, amongst many many others.
Proofpoint recently announced it has succeeded in shutting down the AdGholas malvertising operation. This large-scale operation was reported to have resulted in malicious adverts being displayed to between 1 million and 5 million individuals per day. Researchers at Proofpoint estimated that between 10% and 20% of computers that loaded the malicious adverts were redirected to websites containing exploit kits. Exploit kits probe for security vulnerabilities in web browsers. If vulnerabilities are discovered, malware is silently downloaded onto the site visitor’s computer. Of course this was just one malvertising operation out of many.
Cost of Malware and Ransomware Infections
Many ransomware variants are capable of moving laterally within a network and replicating. One download may see multiple computers infected. Each infected device is encrypted with a separate key and a separate ransom demand is issued for each infection.
Organizations experiencing multiple infections can be issued with ransom demands of tens of thousands of dollars. In January, Hollywood Presbyterian Medical Center was forced to pay $17,000 for the decryption keys to unlock its computers.
The threat from malware can be far more serious. Malware such as keyloggers can be used to obtain login credentials to corporate bank accounts, allowing criminals to make fraudulent transfers and empty company accounts. Malware can install backdoors that can be used to steal patient data from healthcare organizations. Failing to prevent drive-by malware downloads can prove very costly indeed. Recently, the Ponemon Institute calculated the average healthcare data breach cost to be $4 million. The cost per compromised healthcare record was calculated to be $158.
Prevent Drive-by Malware Downloads
To prevent drive-by malware downloads you need to employ a range of tactics. Good patch management policies can help to ensure that devices are not left vulnerable. Software, browsers, and browser plugins should be kept up to date and patches applied promptly. Plugins and software commonly exploited by cybercriminals include Java, Adobe Flash, and PDF reader, as well as out of date web browsers.
Organizations can prevent employees from being directed to malicious websites by using a web filtering solution. A web filter can be configured to block websites known to contain malware or host exploit kits. A web filter can be used to block third party advertising from being displayed. Block the ad networks, and you will ensure that malvertising is not displayed.
You should also implement Acceptable Usage Policies (AUPs) to limit the websites that employees can visit. A web filtering solution can help in this regard. Employees can be instructed not to visit certain categories of websites which are known to carry a higher than average risk, but a web filter can be used to enforce those policies. By blocking access to gambling websites, pornography, sites containing illegal website content, and other risky websites such as p2p file sharing sites, risk can be greatly reduced.
A web filtering solution cannot prevent all data breaches and malware attacks, but it is a vital element of cybersecurity defenses that should not be ignored. It is one of the most important controls to employ to prevent drive-by malware downloads.
Pressure has been mounting recently on corporations in America to block pornography on WiFi networks open to the public. McDonalds and Starbucks have responded by announcing they will be blocking porn on public WiFi networks in their restaurants and coffee shops.
Early last week, McDonalds announced that it is now using WiFi network web filtering to block pornography – and child pornography – in its 14,000+ restaurants in the United States. The technology had been introduced earlier this year, although the move has only just been announced by the fast food chain. McDonalds is one of the first – and largest – organizations to block pornography on restaurant WiFi networks.
A couple of days later, Starbucks announced that that the company will also be using WiFi network web filtering to block pornography in its coffee shops in the United States. Starbucks will be evaluating web filtering solutions to block pornography in order to ensure the implementation of a web filter does prevent customers accessing non-pornographic websites. Once that process has been completed, the web filtering solution will be rolled out across its 12,200+ U.S. coffee shops followed by its company-owned stores around the world.
While no figures have been released by either organization about the extent to which their WiFi networks are being used to view pornography, online safety organizations have been warning corporate America that the practice is becoming more prevalent and the risk to minors is considerable if efforts are not made to block pornography on restaurant WiFi networks.
Pressure by Anti-Pornography Organizations to Block Pornography on WiFi Networks Pays Off
Internet safety organization Enough is Enough launched its National Porn Free Wi-Fi campaign two years ago and has been placing pressure on corporate America to use WiFi network web filtering to block pornography and prevent access to illegal child pornography on restaurant WiFi networks.
Public WiFi networks offer a higher degree of anonymity than home and work Internet connections, and an increasing number of individuals are actively seeking unfiltered WiFi networks to view, download, and share inappropriate and illegal images.
Enough is Enough – whose mission is to make the Internet safer for children and families – gathered over 50,000 signatures from members of the public and has the backing of more than 75 partner organizations. Over the past few months, pressure has been placed on Starbucks – the largest coffee shop chain in the United States – to block pornography on WiFi networks and to prevent inappropriate material from being accidentally or deliberately viewed by minors.
Many smaller restaurant chains have already taken the decision to block pornography on WiFi networks that are provided for customers. Panera Bread and Chick-fil-A have been using WiFi network web filtering to block pornography and keep customers safe for a number of years, yet the larger chains have only just been convinced that it is important to block pornography on restaurant WiFi networks.
Donna Rice Hughes, President of Enough Is Enough, praised Starbucks and McDonalds for implementing a WiFi filtering solution to restrict access to pornography. She said “We will vigorously continue to encourage other businesses and venues such as hotels, airlines, shopping malls, and libraries to filter pornography and child abuse images on publicly available Wi-Fi in order to protect children and families.”
Another day passes and another ransomware variant emerges, although the recently discovered Ranscam ransomware takes nastiness to another level. Ranscam ransomware may not be particularly sophisticated, but what it lacks in complexity it more than makes up for in maliciousness.
The typical crypto-ransomware infection involves the encryption of a victim’s files, which is accompanied by a ransom note – often placed on the desktop. The ransomware note explains that the victim’s files have been encrypted and that in order to recover those files a ransom must be paid, usually in Bitcoin.
Since many victims will be unaware how to obtain Bitcoin, instructions are provided about how to do this and all the necessary information is given to allow the victim to make the payment and obtain the decryption key to unlock their files.
There is usually a time-frame for making payment. Usually the actors behind the campaign threaten to permanently delete the decryption key if payment is not received within a specific time frame. Sometimes the ransom payment increases if payment is delayed.
Ranscam Ransomware will not Allow Victims to Recover Their Files
Rather than encrypting files and deleting the decryption key, Ranscam ransomware threatens to delete the victim’s files.
The ransomware note claims the victim’s files have been encrypted and moved to a hidden partition on their hard drive, which prevents the files from being located or accessed. The payment requested by the actors behind this scam is 0.2 Bitcoin – Around $133 at today’s exchange rate.
While the ransom note claims that the victim’s files will be moved back to their original location and will be decrypted instantly once payment is received, this is not the case.
Unfortunately for the victims, but the time the ransom note is displayed, the victim’s files have already been deleted. Paying the ransom will not result in the encrypted files being recovered. A decryption key will not be provided because there isn’t one.
Researchers at Talos – who discovered the Ranscam ransomware variant – noted that the ransomware authors have no way of verifying if payment has been made. The ransomware only simulates the verification process. There is also no process built into the ransomware that will allow a victim’s files to be recovered.
Backup Your Files or Be Prepared to Lose Them
Many ransomware authors have a vested interest in ensuring that a victim’s files can be recovered. If word spreads that there is no chance of recovering encrypted files, any individual who has had their computer infected will not pay the ransom demand. Locky, CryptoWall, and Samsa ransomware may be malicious, but at least the thieves are honorable and make good on their promise. If they didn’t, discovering that files had a locky extension would be a guarantee that those files would be permanently lost.
There are new ransomware variants being released on an almost daily basis. Many of the new variants are simplistic and lack the complexity to even allow files to be recovered. The discovery of Ranscam ransomware clearly shows why it is essential to make sure that critical files are regularly backed up. Without a viable backup, there is no guarantee that files can be recovered and you – or your organization – will be at the mercy of attackers. Not all will be willing – or able to – recover encrypted files.
The developers of CryptXXX ransomware have made some updates to the malicious software recently. A new campaign has also been launched which is seeing an increasing number of Joomla and WordPress websites compromised with malicious code that directs visitors to sites containing the Neutrino exploit kit.
The latest CryptXXX crypto-ransomware variant no longer changes the extension of files that have been encrypted, instead they are left unchanged. This makes it more difficult for system administrators to resolve an infection by restoring files from backups, as it is much harder to determine exactly which files have been encrypted.
The ransomware developers have also changed the ransom note that is presented to victims and the Tor address for payment has also been changed. The payment site has been changed frequently, having used names such as Google Decryptor and Ultra Decryptor in the past. The authors have now changed the site to Microsoft Decryptor. This is the second time the payment site has been renamed since June 1. Unfortunately for victims that experience difficulties making the payment, there is no method of contacting the attackers to explain about payment issues.
CryptXXX crypto-ransomware has previously been spread using the Angler exploit kit, although the ransomware is now being distributed using Neutrino. Neutrino is primarily used to exploit vulnerabilities in PDF reader and Adobe Flash to download CryptXXX.
CryptXXX Crypto-Ransomware and CryptoBit Distributed in RealStatistics Campaign
WordPress and Joomla sites are being infected at a high rate, with 2,000 sites currently infected as part of the latest campaign according to Sucuri. The company’s researchers have suggested that the actual figure may be closer to 10,000 websites due to the limited range of sites that they have been observing.
It is unclear how the websites are being infected, although it has been suggested that outdated Joomla and WordPress installations are the most likely way that the attackers are gaining access to the sites, although outdated plugins on the websites could also be used to inject malicious Analytics code. The campaign is being referred to as “Realstatistics” due to the URL that is placed into the PHP template of infected sites.
The latest campaign has also been used to push other ransomware variants on unsuspecting website visitors. Palo Alto Networks researchers discovered eight separate Cryptobit variants that were being pushed as part of the latest Realstatistics campaign. The attackers now appear to be using Cryptobit less and have switched to CryptXXX crypto-ransomware in recent days.
Security researchers at ESET have discovered a dangerous new Mac backdoor program which allows attackers to gain full control of a Mac computer. Mac malware may be relatively rare compared to malware used to infect PCs, but the latest discovery clearly demonstrates that Mac users are not immune to cyberattacks. The new OS X malware has been dubbed OSX/Keydnap by ESET. This is the second Mac backdoor program to be discovered in the past few days.
OSX/Keydnap is distributed as a zip file containing an executable disguised as a text file or image. If the file is opened, it will download the icloudsyncd backdoor which communicates with the attackers C&C via the Tor network. The malware will attempt to gain root access by asking for the users credentials in a pop up box when an application is run. If root access is gained, the malware will run each time the device is booted.
The malware is capable of downloading files and scripts, running shell commands, and sending output to the attackers. The malware is also able to update itself and also exfiltrates OS X keychain data.
Second Mac Backdoor Discovery in Days
The news of OSX/Keydnap comes just a matter of hours after security researchers at Bitdefender announced the discovery of another Mac backdoor program called Eleanor. Hackers had managed to get the Backdoor.MAC.Eleanor malware onto MacUpdate. It is hidden in a free downloadable app called EasyDoc Converter.
EasyDoc Converter allowed Mac users to quickly and easily convert files into Word document format; however, rather than doing this, the app installed a backdoor in users’ systems. Infections with Eleanor will be limited as the app does not come with certificate issued to an Apple Developer ID. This will make it harder for many individuals to open the app.
However, if users do install the app, a shell script will be run that will check to see if the malware has already been installed and whether Little Snitch is present on the device. If the Little Snitch network monitor is not installed, the malware will install three LaunchAgents together with a hidden folder full of executable files used by the malware. The files are named to make them appear as if they are dropbox files.
The LaunchAgents open a Tor hidden service through which attackers can communicate with a web service component, which is also initiated by the LaunchAgents. A Pastebin agent is also launched which is used to upload the Mac’s Tor address to Pastebin where it can be accessed by the attackers. The Mac backdoor program can reportedly be used for remote code execution, to access the file system, and also to gain access to the webcam.
Kaspersky Lab has published a new ransomware study that clearly shows the rise in use of the malicious file encrypting software over the past two years. The research shows that companies are firmly in attackers’ sights, with attacks on companies having soared in recent months.
Kaspersky Ransomware Study 2016
For the ransomware study, Kaspersky Lab looked at crypto-ransomware, which uses encryption to lock critical business files as well as windows blockers – ransomware that simply locks victims’ computer screens to prevent files from being accessed. Kaspersky Lab took de-identified data from the Kaspersky Security Network (KSN) and assessed the data from individuals that had encountered ransomware between April 2014 and March 2016.
Kaspersky Lab notes that while the prevalence of Windows blockers is still high, there has been a massive rise in the use of crypto-ransomware over the past 12 months. Between April 2015 and March 2016 there was a 17.7% rise in the number of individuals who encountered ransomware or Trojan downloaders that installed ransomware. During that time frame, 2,315,931 users had encountered ransomware.
The figures show that cybercriminals are now increasingly turning to ransomware to make money, although in terms of the total number of malware encounters, ransomware remains relatively low. From April 2015 to March 2016, the proportion of users who encountered ransomware out of the total number who encountered other forms of malware increased from 3.63% to 4.34%, a rise of 0.7 percentage points.
Ransomware Study Shows Rise in Popularity of Crypto-Ransomware
The Kaspersky ransomware study clearly shows the rise in popularity of crypto-ransomware with cybercriminals. Compared to 2014-2015, the last 12 months has seen the percentage of individuals who encountered crypto-ransomware rise by 25 percentage points. 31.6% of ransomware encounters are now with cryptors. Attacks using cryptors jumped by 5.5% to 718,536 attacks between 2015 and 2016.
Kaspersky Lab also noted a fall in the use of Windows lockers. Attacks using Win-lockers fell by 13.03% over the same period, falling from 1,836,673 attacks in 2014-2015 to 1,597,395 attacks in 2015-2016.
Windows blockers are not particularly sophisticated and are relatively easy to resolve; however, the same is not true of crypto-ransomware infections. An infection with a Windows-blocker can be reversed without paying a ransom demand. The victim could simply re-install their operating system. This may not be an ideal solution, and it can be time consuming, but the victim would be able to recover all of their files.
With crypto-ransomware that is not the case. If a ransom demand is not paid, the victim would not be able to unlock their files. The decryption keys are all held by the attackers. The only way to recover from a crypto-ransomware attack without paying the ransom demand is by restoring files from a backup. If no backup exists, the victim must pay the ransom or forever lose their files. Because of this, victims are more likely to pay the ransom. It is therefore no surprise that cybercriminals are increasingly trying to cryptors.
Businesses Increasingly Being Targeted
The Kaspersky Lab ransomware study shows that businesses are now increasingly being targeted. Not only will businesses be more likely to pay the ransoms, since ransoms are set per device, the infection of a business network of multiple computers would represent a big pay day for an attacker. Between 2014 and 2016, attacks on businesses rose from 6.80% of all attacks to 13.13%.
The ransomware variants used to attack businesses and individuals has changed significantly over the past 12 months. In 2014-2015, CryptoWall accounted for the lion’s share of attacks (58.84%). Other attacks used a variety of different ransomware variants, the main other variants were Cryaki (5.66%) and Scatter (4.40%).
In 2015-2016, the main ransomware variant was Teslacrypt, which accounted for 48.81% of ransomware attacks. However, many new variants were also extensively used. CTB-Locker accounted for 21.61% of attacks, Scatter 8.66%, Cryaki 7.13%, CryptoWall 5.21%, and Shade 2.91%. Attacks using Locky were just starting late in the year. Locky accounted for 0.62% of all attacks between 2015 and 2016. The “Others category” decreased considerably from 22.55% of attacks in 2014-2015, to 2.41% in 2015-2016. Kaspersky Lab attributes this to the sharing of crypto-ransomware kits by ransomware developers.
A researcher from Google’s Project Zero has blasted Symantec for a long list of security flaws that have placed enterprise users at risk of experiencing cyberattacks. The Symantec antivirus flaws were described as “as bad as it gets”.
Symantec Antivirus Flaws Now Addressed but Companies May Still be at Risk
Symantec has now addressed all of the vulnerabilities and has released patches. All enterprise users of Symantec products are advised to check to make sure that their anti-virus products have been patched. While updates have been pushed out and should be applied automatically, users should check to make sure they have been correctly applied. Not all products can be updated automatically.
Malicious actors could potentially use the flaws to take control of enterprise computers. Entire networks could potentially be compromised. Malicious actors would not even require users to take any action to exploit the flaws. Many could be exploited simply by sending users an email.
According to Google researcher Tavis Ormandy who discovered the flaws, “millions of companies have been put at risk.” The security flaws affect all enterprise anti-virus products sold by Symantec, including Norton products.
Symantec was notified of the flaws and acted quickly to address all of the vulnerabilities, although the company was criticized for not discovering the flaws itself, especially considering their severity. Ormandy discovered that Symantec had used code from open source libraries to unpack compressed files. That code was four years out of date in once case and seven years out of data in another. Ormandy said in a recent blog post that “Dozens of public vulnerabilities in these libraries affected Symantec, some with public exploits.”
Other Symantec antivirus flaws were discovered that were potentially far more serious. Symantec used code to unpack and analyze ASPack compressed files which could be exploited to trigger a buffer overflow without any user interaction.
“An attacker could easily compromise an entire enterprise fleet using a vulnerability like this.” Said Ormandy.
In many cases, components in anti-virus software run under the highest level of privileges possible when this is unnecessary. This introduces unnecessary risk. Ormandy pointed out that many of the Symantec antivirus flaws could be exploited allowing remote code execution and could be used to create computer worms.
Antivirus Software Should Be Extensively Tested for Security Flaws
Symantec and other anti-virus software providers preach about the importance of protecting against threats, yet all too often they have failed to address serious flaws in their own products and have not even applied patches that have been available for years.
The Symantec antivirus flaws may be making headline news at the moment, but the company is far from the only antivirus software provider to have allowed vulnerabilities to persist in security products. Enterprises rely on these security products to protect their end points and networks and expect the software to be bulletproof. Enterprises do not expect the products could actually introduce risks.
All software developers must conduct rigorous checks of their software and need to scan for vulnerabilities in their own code, as well as that taken from third party developers. Ormandy said, “This means monitoring for new releases of third-party software used, watching published vulnerability announcements, and distributing updates. Nobody enjoys doing this, but it’s an integral part of secure software development.”
Cybercriminals are taking advantage of hospital legacy system security vulnerabilities and are installing malware on medical devices such as blood gas infusers. The malware is used to steal data or launch attacks on other parts of healthcare networks. Specialist devices operating on hospital legacy systems are being attacked with increasing frequency and, in many cases, the attacks are going undetected for long periods of time. Once malware has been installed on the devices, hackers are able to conduct attacks from within the network.
The malware allows attackers to download a range of tools that serve as backdoors. They are able to move freely around the network and search for data. Many hospitals are completely unaware that their networks have been compromised and that they are under attack. When the attack is finally identified, it is often too late and data has already been stolen.
The Risk of Hospital Legacy System Security Vulnerabilities Being Exploited is Considerable
In the past few days, researchers at TrapX Security have issued an update to a security report that was first released last year. In 2015, TrapX Security warned of the risk of medical devices being targeted by cybercriminals and of hospital legacy system security vulnerabilities being exploited.
The company’s researchers explained that many healthcare providers had been attacked via their medical devices and warned that additional protections needed to be put in place to prevent the devices from being used to gain access to otherwise secure networks. Security researchers call the attack vector MEDJACK – short for medical device hijack.
Medical devices often run on hospital legacy systems which cannot be changed or updated. Hospital legacy systems security vulnerabilities are often allowed to go unpatched. Hospitals have addressed some of these vulnerabilities and have implemented a host of new security controls to block attacks and detect malware. However, TrapX Security has reported that cybercriminals are managing to bypass these new security controls using old malware.
Old Malware Being Used to Gain Access to Healthcare Data
Researchers have discovered that security software is failing to identify the threat from old malware. These old malware variants may not be effective against the latest operating systems which have had the vulnerabilities that they exploit plugged. However, they are still effective against hospital legacy systems.
The researchers discovered that some attackers had used the MS08-067 worm which exploits vulnerabilities in early versions of Windows. The vulnerabilities were addressed in Windows 7 and the worm is no longer considered a security risk. Even if security software detects the worm, since it is not believed to pose a risk it is either not flagged or the security alert is ignored. However, medical devices are vulnerable if they run on older operating systems. Attackers have also embedded highly sophisticated tools in the worm. Even if the threat is detected, security software does not recognize that the risk of attack is actually high.
TrapX Security has warned that these infections are going undetected for long periods of time due to a lack of security on medical devices or the operating systems on which they run. Consequently, attackers can steal sensitive medical data over long periods of time. Unfortunately, once a backdoor has been installed, it can difficult to detect. Many security systems do not scan medical devices for malware and lateral movement within the network is similarly difficult to detect.
To prevent attacks on medical devices, healthcare organizations should, as far as is possible, isolate the devices and only run them inside a secure network zone. That zone should be protected by an internal firewall, and the devices should not be accessible via the Internet. If patches and updates are available, they should be installed to address hospital legacy system security vulnerabilities. If medical devices cannot be updated and have reached end-of-life, they should be retired and replaced with devices that have the necessary protections to prevent device hijacking.
Many top companies have not done enough to prevent email spoofing using their domains. A new study conducted by security firm Detectify has revealed that many top website domains are wide open to abuse because email servers have been misconfigured or do not use authentication.
Website Owners are Not Doing Enough to Prevent Email Spoofing
Detectify conducted the study to determine how widespread the problem really is. The top 500 Alexa ranked websites were scanned to determine whether vulnerabilities existed that would allow spammers to send spoofed emails from the domains. The Swedish security firm found that fewer than half of the websites tested had configured their email servers correctly. The majority had either misconfigured their email servers or had failed to use authentication, which could prevent email spoofing. 276 of the domains were discovered to be vulnerable. More than half of the most visited websites could therefore be used by spammers to send spoofed emails.
Email spoofing is the sending of emails using a forged email address. This can either be the sending of an email that appears to come from a particular domain – Using a very similar domain name for example – or sending fake emails from the domain itself. In the case of the former, there is little companies can do to prevent this and it is largely down to email recipients to carefully check the sender’s address.
However, organizations can take steps to prevent spammers from sending emails from their own domains. If fake emails are sent from their domains customers may be fooled into thinking the messages are genuine. Criminals use email spoofing for phishing, spearphishing, and malware/ransomware campaigns. It is easier for them to achieve their objective if the message recipients trust the domain from which the email is sent.
How to Prevent Email Spoofing
There are three main ways that companies can address vulnerabilities and prevent domain spoofing. The most common method is to use the Sender Policy Framework, or SPF. By using this setting the website owner can specify which servers are permitted to send emails using the domain. There are three possible settings – hardfail, softfail, and neutral. To prevent email spoofing, hardfail should be selected. This will reject suspected spam emails and will ensure they are not delivered. If the softfail setting is used, emails will still be delivered although they should be marked as suspected spam. If neutral is used there is no control and all emails will be sent and delivered.
The 276 domains that Detectify discovered were vulnerable had used the softfail or neutral settings. Softfail is often used instead of hardfail to prevent the loss of emails that are incorrectly flagged. However, many free email providers such as Gmail fail to mark messages as spam if the softfail setting has been used.
Detectify recommended that websites use the hardfail setting and also use DMARC – Domain Based Message Authentication Reporting and Conformance. DMARC is a much more reliable way to prevent spoofed emails from a domain. DMARC creates a link between the email and the domain name. This makes it easier to determine whether an email is genuine or if it just looks real. DMARC also sends reports to advise the domain owner who is sending emails from their domain.
However, only 42% of the websites tested used DMARC, and in many cases, the settings had been configured incorrectly. While SPF and DMARC are not infallible, they can make it much harder for spammers to send spoofed emails.
Healthcare ransomware infections have made the headlines in recent weeks, although the University of Calgary ransomware attack shows that no organization is immune: In fact, university ransomware attacks are on the rise.
Organizations in the healthcare and financial sectors are the main targets for cybercriminals, although education is the third most likely industry to be attacked. Universities store huge volumes of highly sensitive data and state-sponsored hacking groups frequently conduct attacks.
Foreign governments are keen to obtain research data and ransomware attacks on universities may just be a smokescreen. All too often DDoS attacks are performed for this purpose, yet ransomware can be just as effective. While IT departments scramble to secure systems and recover data, attackers may be plundering data.
University of Calgary Ransomware Attack: $20K Paid for Decryption Keys
The University of Calgary ransomware attack occurred late last month and resulted in computer systems being severely disrupted. The IT department worked around the clock in an attempt to contain the infection and restore computer services one by one. While the University had made backups of critical data, the decision was taken to pay the attackers’ ransom demand as a precaution. To obtain the decryption keys the University had to pay the attackers $20,000.
However, even after paying the ransom, unlocking the encryption and recovering data has been a long winded process. The decryption keys had to be assessed and evaluated, and the process of decrypting the infection took a considerable amount of time.
If multiple computers are infected with ransomware, separate decryption keys are required for each device. Each computer must be restored separately and decryption keys do not always work and may not allow all data to be recovered.
The keys have to be used with care and an infection can take up a considerable amount of an IT department’s time to resolve. Systems and data need to be checked after the infection has been removed and additional cybersecurity measures implemented to protect against future attacks.
The University of Calgary ransomware attack has cost tens of thousands of dollars to resolve and shows that paying the attackers ransom demand is not a quick fix that will enable files to be quickly recovered. The recovery process is time consuming, expensive, and requires a considerable amount of resources.
During the time that systems are down, workflows are seriously disrupted. In the case of university ransomware attacks lives may not be put at risk as is the case with healthcare attacks, but the costs of ransomware attacks on universities can be considerable. The total cost of resolving a ransomware infection is far in excess of any ransom payment.
Protecting Against University Ransomware Attacks
Unfortunately for universities, protecting against ransomware can be difficult as public and private networks often overlap. Staff and students are often allowed to connect personal devices to networks, and controlling devices that connect to networks can be a difficult task. While businesses can conduct cybersecurity training and can teach staff basic security best practices to adopt, this can be difficult for universities with huge volumes of staff, students and researchers.
It is therefore important to implement a number of strategies to reduce the risk of a ransomware attack being successful.
It is essential that regular data backups are made and backup devices must be air-gapped. Staff and students should be encouraged to save files on backed up network drives, and cybersecurity training should be provided where possible. Students should be informed of the risk and advised of security best practices via email and noticeboards.
Many universities already use a web filtering solution to control the content that can be accessed via university wired and WiFi networks. Web filters can also be configured to reduce the risk of drive-by malware downloads. Anti-spam solutions can also prove effective as part of a multi-layered cybersecurity strategy and can prevent malicious emails from being delivered.
Technology should also be implemented to identify intrusions when they occur. A network intrusion detection system is a wise precaution alongside traditional anti-virus and anti-malware solutions.
It may not be possible to prevent all university ransomware attacks, but it is possible to manage risk and reduce the damage caused if ransomware is installed on devices or networks.
The Acer cyberattack recently reported to the California attorney general was due to an unspecified “security issue” on the company’s online store. Acer recently discovered that an unauthorized third party had gained access to its server and had stolen the data of its customers. Customers affected by the breach had made a purchase through Acer’s online store between May 12, 2015 and April 28, 2016.
Full Credit Card Information of Customers Stolen in Acer Cyberattack
Affected customers’ names, addresses, credit card numbers, card expiry dates, and CVC codes were all potentially stolen in the attack. Acer has pointed out that Social Security numbers were not recorded and were not obtained by the attackers. Acer does not believe that customer login details were stolen; however, the theft of password and login data could not be ruled out.
All individuals impacted by the breach do face a significant risk of suffering financial losses and must therefore keep a close check on their credit card statements for any sign of fraudulent activity. Due to the high level of risk Acer has recommended that all customers impacted by the breach place a credit freeze and fraud alert on their files. Credit reports should also be obtained from each of the credit agencies.
The incident has been reported to law enforcement and an investigation is ongoing. Acer also brought in external cybersecurity experts to assist with the investigation.
It is unclear how the Acer cyberattack occurred and whether the attackers gained access to the company’s systems in May last year or whether the attack occurred recently and resulted in a year’s worth of data being stolen. However, Acer did confirm to PCWorld that customers’ have been placed at risk because their data were “inadvertently stored in an unsecured format.”
In a statement issued by the Taiwanese computer company, Mark Groveunder Vice President, Customer Service for the Pan-American region said “We regret this incident occurred, and we will be working hard to enhance our security.” The company’s payment processing company has been informed of the breach and customers have now been notified by mail.
Recent research has highlighted the need for greater controls to prevent minors from accessing pornography. The UK’s Middlesex University recently conducted a study on 1,001 children between the ages of 11 and 16. The study revealed 28% of children aged either 11-12 had viewed online pornography, while the percentage increased to 65% for 15-16 year olds. 94% of those children had seen online pornography by the age of 14. In total, more than half of the children who took part in the survey – 53% – had viewed sexually explicit content online.
The survey showed that approximately one fifth of children who had seen pornography online had actively searched for it; however, 28% claimed to have viewed pornographic material accidentally, via popup windows that had appeared when surfing the Internet for instance.
More Must be Done to Prevent Minors From Accessing Pornography Online
Peter Wanless, chief executive of the NSPCC – The National Society for the Protection of Cruelty to Children – said, “A generation of children are in danger of being stripped of their childhoods at a young age by stumbling across extreme and violent porn online.”
The Children’s Commissioner for England, Anne Longfield is concerned. Not only about the number of children that are viewing age-inappropriate material online, but also how difficult it is for parents to control what their children can access online.
She points out that this is the first generation of children that have Internet-enabled devices. The technology has “taken the Internet from the front room, where parents can monitor use, to their bedrooms or the playground, where they can’t.”
Parents must take responsibility for controlling the web content that can be accessed on home networks. Businesses must also take steps to ensure that pornography cannot be viewed on public Wi-Fi networks.
Wanless says, “Some companies have taken the initiative when it comes to online safety, and we will continue to put pressure on those that have not yet done so.”
Blocking Access to Online Pornography with Web Filters
Any business that provides customers with access to their Internet via Wi-Fi hotspots should take steps to ensure that access to age-inappropriate material is restricted. Providing customers with unrestricted access to the Internet could potentially allow minors to accidentally or deliberately access online pornography.
Hotels, restaurants, coffee shops, shopping malls, retail outlets, and public Wi-Fi hotspots should have controls in place to block the accessing of pornography.
By implementing a web filtering solution, it quick and easy to prevent pornographic material from being viewed on the network. Many web filtering solutions, such as WebTitan Cloud for WiFi, can be easily configured to block pornographic material and pop-ups. WebTitan Cloud for WiFi can also be configured using blacklists, such as those issued by the Internet Watch Foundation. The IWF maintains a list of webpages known to contain child pornography and child abuse images.
If you want to prevent minors from accessing pornography while connected to your WiFi hotspots, contact the TitanHQ team today and find out how you can use WebTitan Cloud for WiFi to keep your Wi-Fi network secured.
Organizations can use the NIST Cybersecurity Framework to assess their cybersecurity programs, but many may discover they have not done nearly enough to reduce the risk of cyber incidents. Recent research conducted by RSA suggests that three quarters of companies have a significant cybersecurity risk exposure and are ill prepared to prevent and deal with cybersecurity attacks.
This is the second year that the RSA Cybersecurity Poverty Index has been produced, and the second year running that 75% of organizations have shown that they face a high risk of cyber incidents occurring.
The research shows that organizations are investing heavily in perimeter defenses, yet a majority have under-developed incident response capabilities. “We need to change the way we are thinking about security, to focus on more than just prevention – to develop a strategy that emphasizes detection and response,” said Amit Yoran, CEO of RSA.
RSA suggests that organizations that invest more heavily in detection and response technologies are in a much better position to defend against cyberattacks than organizations that concentrate on perimeter defenses. However, more than half of the organizations that took part in this year’s study have virtually non-existent incident response capabilities.
The study revealed that the risk of cyber incidents is not particularly well understood by many organizations, and that it often takes a security incident that negatively impacts the business before organizations implement appropriate defenses to defend against cyberattacks. In many cases, businesses simply do not understand how cyber risk can affect their organization and it takes a major incident to make that crystal clear. Organizations that regularly deal with cyber security incidents have a much better understanding of the need to boost defenses, and of the technology needed to shore up security.
Too Little Being Done by the Majority to Address the Risk of Cyber Incidents
The number of organizations taking part in this year’s study more than doubled. Study participants numbered 878 this year, and came from 81 countries around the world.
While organizations are still exposed to a high risk of cyber incidents, this year’s data show that things are improving. Many organizations now have more mature capabilities. This year, 7.4% of respondents said their organizations had advantaged capabilities compared to only 4.9% last year.
45% of respondents said their ability to assess and mitigate cybersecurity risk was virtually non-existent. Only a quarter (24%) of respondents classed their organization as being mature in this area.
Interestingly, the financial service industry, which is believed by many to have relatively advanced cybersecurity protections, was not rated as highly as expected. Last year, 33% of organizations in the financial services industry rated their capabilities as developed or advantaged, while this year only 26% rated their capabilities as such. The aerospace and defense industries had the highest rated organizations in this area (39%) while government organizations and the energy industry rated capabilities the lowest (18%).
EMEA organizations had the highest level of overall maturity with 29% of respondents from these countries rating their capabilities as advantaged or developed. APJ organizations came second with 26%, while organizations in the Americas were lowest at 23%.
This week saw a host of updates issued by Microsoft to address critical flaws in Windows, although 44 security vulnerabilities in total have been addressed in the updates. These vulnerabilities affect a wide range of its products including Windows, Internet Explorer, Edge, and many of its Microsoft Office products. The updates were spread across 16 security bulletins, 6 of which were rated by Microsoft as critical. The remaining patch bundles were marked as important.
Critical Flaws in Windows Addressed this Patch Tuesday
To address the latest critical flaws in Windows, all of the patches should be applied as soon as possible. However, some are more important than others and should be prioritized. MS16-071 is perhaps the most important, especially for organizations that run their DNS server on the same machine as their Active Directory server. This update addresses critical flaws in Windows Server 2012 and Windows Server 2012 R2.
MS16-071 addresses a single flaw in Microsoft’s DNS server; however, the flaw is highly serious. Malicious actors could potentially exploit this vulnerability which allows remote code execution if an attacker send malicious requests to the DNS server. The update modifies how the DNS servers handle requests.
Microsoft has also issued updates to address vulnerabilities in Internet Explorer – MS16-063 – and Microsoft Edge – MS16-068. These two flaws would allow an attacker to gain the same rights as the current user if that individual visits malicious websites configured to exploit the vulnerability.
MS16-070 should also be updated as a priority. This security bulletin addresses a number of flaws, one of which could be exploited via spam email. It addresses vulnerability CVE-2016-0025, which concerns the Word RTF format. This could be exploited to yield RCE to the attacker. Worryingly, an attacker could exploit the flaw without an email even being opened, should that message be viewed using message preview in Microsoft Outlook.
Adobe Flash Zero Day Being Actively Exploited
While all of these updates are important, there is an even bigger worry. A new zero-day vulnerability in Adobe Flash Player has been discovered by Kaspersky Lab researchers. Adobe has been alerted that an exploit already exists for CVE-2016-4171 and that it is being actively exploited in the wild. At present, the vulnerability is being exploited in targeted attacks on organizations by a new hacking group referred to by Kaspersky Lab as “ScarCruft.”
Earlier this week, Adobe said it will delay the issuing of updates in order to address this new vulnerability. CVE-2016-4171 affects Adobe Flash v 22.214.171.124 and previous Windows, Mac, Chrome OS, and Linux versions. Updates are expected to start rolling out today.
Researchers at FireEye have reported that the Angler Exploit Kit has been updated and that it is now capable of bypassing Microsoft’s Enhanced Mitigation Experience Toolkit (EMET) protection – the first time this behavior has been observed in the wild.
Angler Exploit Kit Could be Used to Deliver any Malicious Payload
The Angler exploit kit is being used to exploit vulnerabilities in Silverlight and Adobe Flash plug-ins. If vulnerabilities are found, Angler downloads its malicious payload: TeslaCrypt ransomware. Teslacrypt was closed down a few weeks ago and the authors released a universal decryption key that can unlock all infections. Anti-virus firms have since developed tools that can be used to remove TeslaCrypt infections. However, it is probable that the Angler exploit kit will be updated to deliver other malicious payloads for which there is no known fix. Many distributors of TeslaCrypt have already transitioned to CryptXXX.
Currently EMET protections are only being bypassed on devices running Windows 7, although it is probable that attackers will soon develop EMET bypasses that work on more recent versions of Windows. That said, updating to later versions of Windows will help organizations improve their security posture. If an upgrade is not possible or practical, sys admins should ensure that patches are applied promptly. If possible, ActiveX should also be disabled as should Flash and Silverlight plugins. Uninstalling unnecessary software and disabling plugins will reduce the attack surface.
EMET was developed to prevent malicious actors from exploiting memory corruption vulnerabilities, and while this has proved effective at some preventing attacks, the bypass shows that Microsoft’s protection is not 100% effective. While EMET can be used to reduce the risk of ransomware and other malware infections, system admins should not rely on EMET alone. Multi-layered security defenses should be employed to keep networks protected, as this bypass clearly shows. It is still essential to use anti-virus and anti-malware software and to keep definitions up to date.
While efforts can be made to prevent exploit kits from taking advantage of vulnerabilities in plugins, enterprises can reduce risk further by stopping end users from visiting websites known to host exploit kits. By implementing a web filtering solution and restricting access to certain categories of website, enterprises can greatly enhance their security posture.
Microsoft has recently given Windows users a new incentive to upgrade to Windows 10: A ransomware worm called ZCryptor. The new ransomware variant exhibits worm-like capabilities and is able to self-replicate and infecting multiple devices. The malicious file-encrypting software infection will not be prevented by upgrading to the latest version of Windows, although additional protections are included in the Windows 10 release to make infection more difficult.
The new ransomware variant, called ZCryptor.A, is primarily distributed via spam email messages containing malicious macros, although the Microsoft security advisory indicates the ransomware worm is also installed via fake installers such as those claiming to update Adobe Flash to the latest version.
If ZCryptor is installed, the ransomware searches for removable drives and installs an autorun.inf file on the device. When the drive is disconnected and connected to another computer, the ransomware is able to spread, infecting a new machine.
The ZCryptor ransomware worm is capable of encrypting 88 different file types according to the Microsoft advisory, although some samples have been detected that are capable of infecting as many as 121 different files types.
Once installed, the ransomware generates a fake Windows alert indicating a removable drive cannot be detected. The pop-up will continue to be displayed while the ransomware is running and is communicating with its command and control server. The purpose of the pop-up is unclear, although presumably this is generated to prompt the user to disconnect the drive. This could be a ploy to get the victim to connect the removable drive to a different computer thus spreading the infection.
The ransomware worm displays an HTML window explaining that all personal files on the computer have been encrypted. A ransom demand of 1.2 Bitcoin is demanded ($500) for the decryption key to unlock the infection. Victims are given 4 days to pay the ransom or the ransom demand increases to 5 Bitcoin. The attackers claim that after 7 days the unique decryption key will be permanently destroyed, and all encrypted files will remain permanently locked.
While anti-virus software developers have been able to find vulnerabilities in a number of other ransomware variants and develop fixes, no known fix currently exists for a ZCryptor infection. Victims will either have to restore all of their files from a backup or will have to pay the ransom. Of course, there is no guarantee that the attackers will make good on their promise and will supply a valid decryption key.
Ransomware Worm Represents Next Stage of Malware Development
Many organizations now employ web filtering solutions such as WebTitan to block malicious URLs containing exploit kits. By blocking these attack vectors, it is becoming harder for cybercriminals to infect computers.
Spam filters have similarly been developed to be much more efficient and effective at blocking malicious spam email. SpamTitan now blocks 99.97% of spam, making it much harder for malicious attachments and links to reach end users.
Due to the improved cybersecurity protections in place in many organizations, ransomware developers have had to develop new methods to spread infections. The development of ransomware that exhibits worm-like behavior does not come as a surprise. Security researchers believe that these ransomware worms are likely to become much more common and that self-propagating ransomware and malware will soon become the norm.
The Zuckerberg Twitter hack has clearly demonstrated the danger of password reuse. Zuckerberg used the same password for Twitter as he did for his Pinterest and LinkedIn accounts. In spite of the Facebook founder, chairman, and CEO’s lofty position at the top of the world’s most popular social media network, he is guilty of poor data security practices like many others.
In addition to reusing passwords, Zuckerberg also chose a password of 6 digits with no capital letters, symbols, or numbers and did not change it for at least three years. The password was revealed to be “dadada.”
Mark Zuckerberg Twitter Hack Stemmed from the LinkedIn Data Breach
A collective known as OurMine was responsible for the Mark Zuckerberg Twitter hack. The collective, which is understood to hail from Saudi Arabia, gained access to data from the LinkedIn breach. The data were listed for sale a few days previously by a hacker operating under the name of “Peace”.
The LinkedIn passwords were not stored as plaintext, so a little effort was required to reverse the hash to obtain the password. While SHA-1 was thought to be impossible to reverse, it has since been shown to be a relatively straightforward task unless the passwords are also salted. In the case of LinkedIn, they were not.
Simply enter in the SHA-1 hash of a password into one of many reverse hash calculators and the plaintext password will be revealed. A search of the keyword phrase “how to reverse a sha1 password” will reveal many online options for doing so. Once the password had been obtained, access to online accounts was possible.
The Zuckerberg Twitter hack did not appear to cause anything other than some embarrassment. The group notified Zuckerberg of the hack by tweeting him using his own account, saying “we are just testing your security.” While the tweet said that Zuckerberg’s Instagram account was compromised, it has since been confirmed that this account was secure all along, as was Zuckerberg’s Facebook account.
While it is embarrassing, it should be pointed out that Zuckerberg was not a regular Twitter user, having only sent 19 tweets from his account in the past four years. His compromised Pinterest account was similarly rarely used.
Spate of Account Hacks Reported After Major Data Leaks
Other individuals were not quite so fortunate. Since the data from the LinkedIn breach was made available online, numerous celebrity social media accounts have been compromised. The Twitter accounts of celebrities such as Keith Richards and Kylie Jenner were hacked, as was the account of Tenacious D. The latter’s account was used to send a tweet saying Jack Black had died.
While these hacks have not been confirmed as stemming from the LinkedIn breach (or the MySpace or Tumblr breaches) the spate of account hijacks suggest as much.
TeamViewer GmbH was also a victim, having had numerous accounts compromised recently. The company provides remote desktop software and a number of users claim that the hacking of GmbH employee accounts enabled attackers to compromise their computers and authorize PayPal and Amazon transactions. This was attributed to “password mismanagement” by GmbH rather than any flaws in their software.
All of these account hacks show how common the reuse of passwords is, and the danger of doing so. What should be particularly worrying for businesses, is many people use their LinkedIn passwords for work accounts, or vice versa. If that password is obtained via a data breach, malicious actors could do a considerable amount of damage.
Important Online Security Best Practices
To improve security and reduce the risk of more than one account being compromised….
Never reuse passwords
Create a complex password for each platform – use symbols, capitals, and numerals
Change your passwords regularly – every month or three months
Use 2-factor authentication if available
Use a password manager to help keep track of passwords
Don’t store your passwords in your browser
Regularly check your email address/username against the Have I Been Pwned? database
A recent ransomware research study has shown the individuals running ransomware campaigns do not actually earn that much money and the success rate of attacks is relatively low. However, the threat from attacks cannot be ignored due to the volume of individuals now running their own ransomware campaigns.
For the ransomware research study, web intelligence company Flashpoint trawled underground forums and marketplaces and monitored communications over a period of five months. The purpose of the ransomware research study was to improve understanding of how ransomware campaigns are run, to learn about the players involved, and the tactics they used to run campaigns and infect end users. It helps to know thy enemy when forming a defense strategy against attacks.
For its ransomware research study, Flashpoint investigated Russian ransomware campaigns from December 2015. The attacks were predominantly carried out on organizations and individuals in the West.
Ransomware Research Study Shows Campaigns are Not as Profitable as Many People Think
Considering the disruption caused and the money lost by victims of ransomware attacks, many people believe the criminals behind the campaigns are making big bucks, but that is not necessarily the case. In fact, even “ransomware bosses” – the individuals offering ransomware-as-a-service – are not raking in anywhere near as much money as many people think.
The majority of cybercriminals who run ransomware campaigns earn well under $10,000 a month. According to the ransomware research study report, only one in five individuals who run ransomware campaigns admitted to earning in excess of this figure. The report suggests that the average monthly earnings from this type of campaign is around $600 per month.
The typical ransom is around $300 per infected computer, although the people who run the campaigns have to give the ransomware bosses 60% of their earnings. They are allowed to keep the remaining 40%, suggesting most of the people running these campaigns only get 2-3 ransoms per month.
The ransomware research study data suggest that far from allowing criminals to obtain big money from ransomware campaigns, the attacks only yield similar returns to other forms of cybercriminal activities. The only difference being the attackers can usually get their hands on money faster. Stealing data such as credit card numbers or healthcare data requires the attacker to find a buyer for those data before any money is received.
The report suggests that the typical infection rate from a campaign is between 5% and 10%, yet few of the victims end up paying the ransom. Many ransomware victims are protected having made backup copies of important files and some are able to unlock the infections using tools from security companies. Others are willing to lose data rather than pay the ransom.
Ransomware bosses that push ransomware-as-a-service using an affiliate model can make around $7,500 per month, which equates to around $90,000 a year – approximately 30 ransom payments per month for the bosses.
Most Ransomware Campaigns are Run by Novices
While there are criminal gangs and highly skilled cybercriminals who invest a lot of time and effort into their ransomware attacks, the report suggests that the majority of attackers are novices; not skilled hackers. The report suggests that many individuals choose to run campaigns using ransomware-as-a-service in the hope that they will get lucky and get a big payout. These individuals tend to run spamming campaigns based on quantity rather than quality, and send high numbers of spam emails using botnets.
Flashpoint’s ransomware research study shows just how easy it is to start sending out ransomware campaigns. This is why so many individuals choose to give it a try. All that is needed is a very small injection of capital to get started, a lack of morals about how money is earned online, and a modicum of knowledge to allow individuals to send out mass spam emails.
Adverts for ransomware-as-a-service are easy to find with the Tor browser and advice on distribution is not difficult to find. Would-be criminals with no experience are recruited with a promise of a big payout, even though the reality is that for most people the payouts will be low.
More experienced and skilled individuals send phishing emails directing victims to websites containing exploit kits, which probe for vulnerabilities and automatically download the ransomware. Another popular method of infection is to sneak adverts containing malicious links onto legitimate advertising networks.
Only a small percentage of attackers are highly skilled. These individuals tend to send out targeted campaigns. These attackers target organizations and businesses with the aim of infecting multiple machines and infiltrating networks causing widespread disruption.
These campaigns tend to involve a considerable amount of planning, and require the attacker to research targets and design targeted emails that have a high change of eliciting the desired response. According to Flashpoint’s director of Eastern European Research and Analysis, Andrei Barysevich, “The success rate of this type of operation is significantly higher, enabling criminals to earn upwards of $10,000 a month or more.”
For organizations infected with ransomware the costs can be severe. Add up the cost of disruption to the business, the time and resources required to remove infections and restore files, and the cost of implementing more robust security measures, and the cost of a ransomware attack could be tens of thousands of dollars.
With no shortage of takers for ransomware-as-a-service, and ever more sophisticated ransomware being developed, organizations must develop a host of defenses to prevent attacks from being successful.
Security researchers have discovered a serious Jetpack plugin vulnerability that places sites at risk of attack by hackers. If you run WordPress sites for your company and you use the Jetpack website optimization plugin, you must perform an update as soon as possible to prevent the flaw from being exploited.
The flaw can also be exploited by competitors to negatively affect search engine rankings by using SEO spamming techniques, which could have serious consequences for site ranking and traffic.
Over a Million WordPress Websites Affected by the New Jetpack Plugin Vulnerability
The Jetpack plugin vulnerability was recently discovered by researchers at Sucuri. The flaw is a stored cross-site scripting (XSS) vulnerability that was first introduced in 2012, affecting version 2.0 of the plugin. All subsequent versions of Jetpack also contain the same Shortcode Embeds Jetpack module vulnerability.
Jetpack is a popular WordPress plugin that was developed by the people behind WordPress.com – Automattic – and has been downloaded and used on more than one million websites. This is not only a problem for website owners, but for web visitors who could easily have this flaw exploited to infect their computers with ransomware or malware. Flaws such as this highlight the importance of using web filtering software that blocks redirects to malicious websites.
While many WordPress plugin vulnerabilities require a substantial skill level to exploit, the jetpack plugin vulnerability takes very little skill at all to exploit. Fortunately, Jetpack has not discovered any active exploits in the wild; however, now the vulnerability has been announced, and details provided online about how to exploit the vulnerability, it is only a matter of time before hackers and malicious actors take advantage.
The flaw can only be exploited if the Shortcode Embeds Jetpack module is enabled, although all users of the plugin are strongly advised to perform a site update as soon as possible. Jetpack has worked with WordPress to get the update pushed out via the WordPress core update system. If you have version 4.0.3 installed, you will already be protected.
Jetpack reports that even if the flaw has already been exploited, updating to the latest version of the software will remove any exploits already on the website.
Over the past few days, rumors have been circulating about a massive MySpace data breach. Initial reports suggested that 427 million usernames and passwords had been obtained by a hacker going by the name of “Peace”. The name should sound familiar. The Russian hacker is the same individual who recently listed 117 million LinkedIn login credentials for sale on an illegal darknet marketplace. The hacker was also allegedly responsible for the 65 million-record data breach at Tumblr.
360 Million Login Credentials Stolen in MySpace Data Breach
Yesterday, Time Inc., confirmed that login credentials had been listed for sale online and that a MySpace data breach had occurred, although it would appear that the stolen data was obtained some time ago. The login credentials are for the old MySpace platform and date to before June 11, 2013. While Time Inc., did not confirm exactly how many login names and passwords had been stolen, Time confirmed that the figure of 360 million that had been reported in the press in the last couple of days was probably accurate.
Usernames, passwords, email addresses, and secondary passwords are reportedly being offered for sale. Out of the 360 million logins, Leakedsourrce.com suggests that 111,341,258 of the stolen records include a username and a password, and 68,493,651 records had a secondary password compromised. Not all of those stolen records also included a primary password.
Since 2013, data security has improved considerably and many companies have enforced the use of numerals, capital letters, and symbols when creating passwords. The stolen data reportedly includes only a small percentage of accounts with a capital letter in the password. This makes the passwords much easier to crack. The algorithm used to encrypt the passwords was also weak.
The login credentials from the MySpace data breach are reportedly being offered for sale for 5 Bitcoin – approximately $2,800.
All old users of the MySpace platform, and current users who joined the website before June 11, 2013 are potentially at risk. MySpace has responded to the breach by resetting all passwords on accounts created before June 11, 2013. When these users visit MySpace again they will be required to authenticate their account and supply a new password.
Additional security measures have been employed to identify suspicious account activity and the data theft is now being investigated. It would appear that no one at MySpace was aware that its database had been breached until the data were offered for sale just before the Memorial Day weekend.
MySpace Breach Shows Why It is Important Never to Reuse or Recycle Passwords
Since the data breach appears to have occurred some time ago, it is probable that many users will have changed their passwords on the site long ago, but the data could still be used to attack past and current users. All too often passwords are recycled and used for other online accounts, and many individuals use the same passwords for different platforms or rarely (or never) change them.
The MySpace data breach shows why it is important to use a different password for each online account and to regularly change passwords on all platforms. In the event of a breach of login credentials, users will only have to secure one account. If there is a possibility that only passwords are still in use on other platforms, MySpace account holders should update their passwords as soon as possible.
Hackers have access to tools that can check to see if account login and password combos have been used on other websites.
After the recent news that TeslaCrypt has been decommissioned comes a new highly serious threat: DMA Locker ransomware.
Malwarebytes has recently reported that DMA Locker ransomware, which is now in its 4th incarnation – could pose a significant threat to businesses and individuals over the coming weeks. Version 4 of the ransomware has already been added to the Neutrino exploit kit and is currently being distributed. Malwarebytes expects DMA Locker ransomware attacks to become much more widespread.
Spate of DMA Locker Ransomware Attacks Expected
DMA Locker ransomware was first seen in the wild in January of this year, yet the malicious file-encrypting malware posed little threat in its early forms, containing numerous flaws that allowed security companies to develop decryption tools.
The early forms of DMA Locker ransomware were capable of encrypting files offline and did not used a command and control server. When files were encrypted, the key to unlock the encryption was stored on the device. This allowed the malware to be reverse engineered to crack the encryption.
A new version of the ransomware was released a month later, yet it used a weak random generator and it was a relatively easy task to guess the AES key. A couple of weeks later saw the release of version 3, which saw previous flaws corrected by the authors.
However, version 3 of DMA Locker ransomware contained another flaw. While it was not possible to decrypt locked files without a decryption key, the attackers used the same key for the entire campaign. If a business had multiple infections, only one key would need to be purchased. That key could then be posted online and be used by other victims.
However, this month version 4 was released. The latest version corrects the issues with version 3 and uses a separate key for each infection. The ransomware also communicates with a command and control server and cannot work offline.
Infection with early versions of the ransomware occurred via compromised remote desktop logins – or logins that were easily guessed. Consequently, the number of recorded infections remained low. However, the latest version has been added to exploit kits which take advantage of vulnerabilities in browsers making silent drive-by downloads of the ransomware possible. This makes attacks much more likely to occur.
The ransomware is potentially highly serious, encrypting a wide range of file types. Many ransomware strains only encrypt specific file types. TeslaCrypt for example was developed to attack gamers, and encrypted saved game files and files associates with Steam accounts. DMA Locker does not search for specific files, and instead encrypts everything that is not in its whitelist of file extensions. It is also capable of encrypting files on network drives, not just the computer on which it has been downloaded.
To prevent attacks, businesses should use web filtering software to block users visiting sites containing exploit kits and stop command and control server communications. Regular backups should also be performed and files stored on air-gapped drives. In case of attack, files can then be recovered without paying the ransom.
A successful CEO fraud scam that resulted in a fraudulent bank transfer being made from company accounts to a cyberattacker has cost the CEO his job.
CEO Fraud Scan Results in Losses of 40.9 Million Euros
Earlier this year, FAAC – an Austrian aircraft component manufacturer – was targeted by attackers who managed to pull off an audacious 50 million Euro ($55 million) CEO fraud scam. A wire transfer was made for 50 million euros by an employee of the firm after receiving an email request to transfer the funds from CEO Walter Stephan. The email was a scam and had not been sent by the CEO.
Unfortunately for FAAC, the CEO fraud scam was discovered too late and the transfer of funds could not be stopped. While the company was able to recover a small percentage of its losses, according to a statement released by FAAC, the company lost 41.9 million Euros as a result of the attack which contributed to annual pretax losses of 23.4 million Euros.
The bank transfer represented approximately 10% of the company’s entire annual revenue. Given the high value of the transfer it is surprising that the transfer request was not queried in person – or over the telephone with the CEO.
The CEO and the employee who made the transfer were investigated but do not appear to have been involved in the scam. The attackers were not believed to be linked to FAAC in any way.
Heads Roll After Huge Losses Suffered
Earlier this year, FAAC sacked its chief finance officer as a direct result of the scam. The CEO was recently sacked following a meeting of the company’s supervisory board. Stephan had worked at the company as CEO for 17 years.
This CEO fraud scam is one of the largest ever reported, although this type of scam is becoming increasingly common. Earlier this year the FBI issued an advisory about the high risk of CEO fraud scams following many attacks on U.S companies over the past year. In April, the FBI reported that $2.3 billion has been lost as a result of this type of scam.
CEO email fraud involves a member of the accounts department being sent an email from the CEO – or another senior executive – requesting a bank transfer be made from the company accounts. A reason is usually supplied as to why the transfer request needs to be made, and why it must be made urgently.
Oftentimes, the scammer and the target exchange a few emails. An email is initially sent asking for a transfer to be made, followed by another email containing details of the recipient account where the funds must be sent and the amount of the transfer. The scams are effective because the request appears to come from within the company from a senior executive or CEO. Oftentimes the attackers manage to compromise the CEO’s email account, and spend time researching the style the CEO uses for emails and who transfer requests have been sent to in the past.
According to the FBI, the average transfer amount is between $25,000 and $75,000, although much larger scams have been pulled off in the past. Irish budget airline Ryanair fell victim to a CEO fraud scam and wired $5 million to a Chinese bank, although the funds were able to be recovered. The Scoular Co., wired $17.2 million to scammers in February last year, while Ubiquiti suffered a loss of $46.7 million as a result of a CEO fraud scam.
Easy Steps to Prevent CEO Email Fraud
There are steps that can be taken that can greatly reduce the risk of these scams being successful.
Implement policies that require all bank transfers – or those above a certain threshold – to be authorized by telephone or through other communication channels.
Ensure bank transfer requests are authorized by a supervisor and are not left to one single employee
Configure spam filters to block spoofed domains to prevent scam emails from being delivered
Provide training to all accounts department staff and warn of the risk of CEO fraud scams
Resolving a hospital ransomware infection may not be as easy as paying the attackers’ ransom demand, as was shown by the Kansas Heart Hospital ransomware attack last week.
Hospital Ransomware Infection Not Removed After Ransom Paid
The Kansas Heart Hospital ransomware attack which occurred last week was the latest in a string of attacks on healthcare organizations in the United States. Ransomware was accidentally installed on a hospital worker’s computer and files were locked and prevented from being accessed.
A ransom demand was received demanding payment for decryption keys to unlock the infection. The decision was taken to pay the ransom to resolve the hospital ransomware infection quickly.
After the ransom was paid, the attackers did not make good on their promise and failed to unlock all of the files. Some Instead the hospital was issued with a second ransom demand.
In this case, the initial ransom demand was relatively low. Ransomware attackers typically demand a fee of approximately $500 per device to unlock an infection. If multiple computers have been infected, that figure is then multiplied by the number of devices that need to be decrypted.
Ransomware locks each individual machine separately, and a different key is required to unlock each one. Otherwise a victim could pay up and then publish their key and no one else would be required to pay.
Kansas Heart Hospital did not disclose how much was paid, but this could well have been the fee to unlock a single machine. However regardless of the amount, the incident shows that even if a ransom is paid there is no guarantee that the attackers will play ball and make good on their promise. Further demands may be made from more Bitcoin. Resolving a hospital ransomware infection may not necessarily mean just paying the ransom demand.
Healthcare Industry Under Attack
Over the past few months the healthcare industry has come under attack from criminals using ransomware. Some authors of ransomware have taken steps to prevent healthcare providers’ computers from being attacked by their ransomware by including checks to determine the environment in which the ransomware has been installed. However, not all attackers feel they have a moral responsibility to prevent attacks which could cause people to come to physical harm.
Hollywood Presbyterian medical center, Alvarado Hospital Medical Center, King’s Daughters’ Health, Kentucky’s Methodist Hospital, California’s Chino Valley Medical Center and Desert Valley Hospital, and MedStar Health have all been attacked with ransomware this year.
That list is likely to continue to grow. Hospitals and medical centers are attractive targets for ransomware gangs. Many healthcare organizations have under-invested in cybersecurity measures to protect their networks and many hospital employees have not received extensive training in security awareness. This makes it easy for attackers to install ransomware.
Furthermore, if patient data are locked this can have a negative effect on patient health. If patients are at risk of harm, organizations are much more likely to respond to ransom demands and pay up to ensure patients do not suffer. If patients are harmed as a direct result of poor investment in cybersecurity or mistakes that have been made by healthcare employees, healthcare organizations are likely to face lawsuits that could result in damages far in excess of the ransom being demanded.
With attacks likely to continue, healthcare providers must take steps to prevent ransomware attacks from occurring, and develop policies that can be implemented immediately upon discovery of a ransomware attack. As the Kansas Heart hospital ransomware attack has shown, paying a ransom is no guarantee that the file encryption will be unlocked. Hospitals may find that they still have to recover files from backups or explore other means of unlocking infections.
The threat from Cerber ransomware has increased substantially after the gang behind the file-encrypting software have leveraged Dridex botnets to deliver a malicious payload that loads the ransomware onto users’ devices.
Cerber ransomware was first discovered in the wild in February 2016, but researchers at security firm FireEye noticed a massive increase in infections in recent weeks. Initially, Cerber ransomware infections occurred as a result of visiting malicious websites hosting the Nuclear or Magnitude exploit kits. Nuclear and Magnitude probe visitors’ browsers for a number of zero day vulnerabilities, although infections primarily occurred by exploiting a vulnerability in Adobe Flash (CVE-2016-1019). Now the ransomware is being installed via infected files sent via spam email.
Cerber differs from many ransomware strains by being able to speak to victims. The ransomware is able to use text-to-speech to tell victims they have been infected and that their files have been encrypted.
Massive Increase in Cerber Ransomware Infections Discovered in April
The number of infections remained relatively low since the discovery of the new ransomware earlier this year; however, there was a massive spike in infections around April 28 according to FireEye. The ransomware was being downloaded using Microsoft Word macro downloaders.
The attached files are usually disguised as invoices, receipts, or purchase orders, while the emails – written in English – urge the user to open the attachment. If macros are enabled on the computer a VBScript will be installed in the victim’s %appdata% folder. If macros are not enabled users will be prompted to enable them in order to view the contents of the file. Doing so will guarantee infection.
Once installed, the script performs a check to determine whether the infected computer has an Internet connection by sending an HTTP request to a website. If an Internet connection is present, the script will perform a HTTP Range Request, that will ultimately result in the final stage of the infection. FireEye reports the technique has previously been used to deliver the financial Trojans Dridex and Ursnif.
Cerber has been configured to encrypt Word documents, emails, and Steam gaming files, which are given a “.cerber” extension. To unlock the encryption, the victims are told to visit one of a number of websites with the domain “decrypttozxybarc”. Further instructions are then provided on how to unlock the encryption, although a Bitcoin ransom must first be paid. In addition to encrypting files, Cerber ransomware adds the victim’s computer to a spambot network.
The ransomware uses a number of obfuscation techniques to avoid detection by spam filters and anti-virus programs. If the emails are delivered and the macros are allowed to run, victims’ files will be encrypted. To prevent infection, it is important to have macros disabled and to be extremely cautious about opening email attachments, and never to open files deliver via email from an unknown sender. The decrypttozxybarc domain should also be added to web filter blacklists.
There are a number of companies that offer web filtering services for MSPs; however, while many managed service providers are happy to provide web filtering to their clients if the service is requested, web filtering is not generally offered to clients as part of an MSP’s range of standard Internet services. Yet, by leveraging web filtering services for MSPs it is possible to substantially increase profits for very little effort.
Web filtering services for MSPs have been developed to be easy to implement, easy to sell to clients, and straightforward to manage, so why are more MSPs not offering web filtering to their clients as part of their Internet services?
Some MSPs may feel that there is not much of a market for web filtering. Draconian Internet usage policies may ensure that Internet access is not abused, yet highly restrictive Internet policies can have a negative impact on staff morale and productivity. Most employees can be trusted to get all of their daily tasks completed, while still occasionally checking Facebook, purchasing something on Amazon, and viewing the occasional YouTube video.
However, providing totally free access to the Internet is unwise. Not preventing employees from accessing illegal and inappropriate website content can cause employers many problems. Some of those problems can prove very costly to resolve. Any organization that has not chosen to filter the Internet – even to a minimal degree – may not be aware of the risks. If MSPs explain these risks, they are likely to find many of their clients will want to sign up for web filtering services.
What are the Main Benefits of Using Web Filtering Services?
There are two main reasons for using a web filter to control Internet content:
Reducing the Risk of Malware Infections
As we have seen in recent months, there is a clear and present danger of a serious malware infection. Cyberattacks are taking place with increasing regularity, new malware is being released at alarming rates, and cybercriminals have embraced ransomware and are using it to extort money out of businesses.
IT teams struggle to implement patches promptly, leaving their networks at risk of attack. This is mainly due to the frequency at which patches are released. Keeping all software – including web browsers and plugins – 100% up to date, 100% of the time is an uphill struggle.
If end users visit malicious websites containing exploit kits, malware and ransomware can be easily loaded onto networks. Issuing staff members with acceptable use policies (AUPs) can reduce the probability of end users visiting high-risk websites, while policies can help to reduce the risk from shadow IT installations, but unless those policies are enforced there is a risk that some employees will break the rules.
Numerous organizations have experienced phishing attacks even when training has been provided on how to identify phishing emails. Unfortunately, scammers are getting much better at crafting highly convincing emails to fool users into visiting websites containing exploit kits that can download malware.
Business email compromise scams have been increasing in recent months, prompting the FBI to issue warnings due to the high risk of attack. Scammers are impersonating CEOs, CISOs, and executives to get end users to visit websites and divulge their login credentials or download malware.
With so many Internet threats to deal with, policies are no longer enough to keep organizations’ networks free from malicious software and infections can prove very costly to resolve.
Controlling Personal Use of the Internet
Many companies take a relaxed attitude to personal Internet use, provided it is kept within certain limits. This is arguably the best option for employers and employees. Blocking personal access to the Internet can have a negative effect on staff morale, and all employees will need to use the Internet from time to time for personal reasons.
That said, there will always be some members of staff that choose to abuse their Internet access and this can lead to serious problems for employers. Not only is there a risk of malware infections, abuse of the Internet can have legal implications for employers. The use of illegal file sharing websites for copyright-infringing downloads, the accessing of illegal website content such as child pornography, or even the viewing of legal pornography in the workplace can cause many HR issues.
Of course, web filtering is not only about blocking access. It allows companies to monitor use of the Internet and identify employees who are breaking the rules before serious HR or legal issues arise. Web filtering also allows organizations to place limits on online activities at certain times of the day to ensure the workforce remains productive and bandwidth is not wasted.
Summary of the Benefits of Filtering the Internet
Blocks malware, ransomware, botnets, adware, and spyware installations
Prevents the accessing of illegal website content
Stops the downloading and installation of shadow IT
Prevents bandwidth wastage
Allows employers to monitor employees’ Internet usage
Prevents many HR issues
Helps organizations to comply with industry regulations
Can help to increase employee productivity
Benefits of Web Filtering Services for MSPs
Protects clients from Internet threats
Easily increases client revenue
Helps MSP’s to attract more clients and win new business
Allows MSPs to provide a more comprehensive range of Internet services
Web Filtering Services for MSPs can be Easily Incorporated into Existing Service Packages
Web filtering services for MSPs no longer require expensive appliances to be purchased, and it is not necessary to use local IT support teams to visit clients to install and configure web filters. In fact, it is not even necessary to install software on clients’ devices or servers at all. Clients can have their Internet filtered within 5 minutes of them saying yes to a sales representative if cloud-based web filtering services are used.
Cloud-based web filtering services for MSPs require clients to make a small change to their DNS settings, something that even the most technically inept employee could be talked through over the phone. By pointing the DNS to the service provider’s servers, the Internet can be filtered quickly and painlessly.
Web filtering services for MSPs can be easily offered to clients alongside managed service providers’ solutions. WebTitan Cloud – and WebTitan Cloud for WiFi – are offered as web filtering services for MSPs without any branding. MSPS are able to add their own logos and corporate color schemes, tailor block pages, and customize reports with their own branding. If required, MSPs can also host the solution within their own infrastructure or use a private cloud for clients.
The management overhead is low and the configuration of new accounts is quick and easy. New client accounts can be set up in approximately 20 minutes. Even reporting is taken care of with a full suite of pre-configured, schedulable reports, including instant email alerts.
The cost for the client is low with only a small spend required per user, per year, and the margins offered by TitanHQ on web filtering services for MSPs are generous. This allows MSPs to easily increase profits, in some cases, by tens of thousands of dollars.
If you want to attract new business, increase client spending, and easily increase profits, web filtering services for MSPs could well be the answer.

This week, a new critical Symantec vulnerability has been discovered that enables an attacker to trigger a memory buffer overflow, allowing root-level control over a system to be gained without any user interaction. The cross-platform security vulnerability affects many Symantec and Norton anti-virus software releases.
Critical Vulnerability in Symantec AVE Scan Engine is “As Bad as it Can Possibly Get”
The critical fault has been found in the core scanning engine used in both Norton and Symantec anti-virus software, including Norton antivirus, and Symantec’s Scan Engine, Endpoint Antivirus, and Email Security, although other products may also be affected. The vulnerability affects Windows, Mac, Linux, and UNIX platforms.
Since the scan engine intercepts all system input and output, the vulnerability could be exploited by an attacker by simply sending a file attachment to a user’s inbox. The user would not even be required to open the file in order for the vulnerability to be exploited.
The vulnerability could therefore allow an attacker to take full control of the device on which the software has been installed with no user interaction necessary. The vulnerability has been described as “as bad as it can possibly get” by Tavis Ormandy – the researcher at Google Project Zero who discovered the security flaw.
Ormandy said that if the vulnerability is exploited it causes kernel memory corruption on Windows because “the scan engine is loaded into the kernel (wtf!!!).” It must be said, unpacking malware in the kernel was perhaps not the best decision. Ormandy also discovered a number of other remote code execution security vulnerabilities in Symantec products.
The new critical Symantec vulnerability has now been addressed – AVE version 20126.96.36.199 – although the remaining vulnerabilities have yet to be remediated. Users of Symantec and Norton branded products will have to wait until a patch is made available.
According to an advisory issued by Symantec, the critical vulnerability affects the AVE scanning engine and occurs “when parsing malformed portable-executable header files.” If one of these malformed portable-executable header files is downloaded in an application or document, or if a malicious website is visited which downloads one of these files onto the device, the flaw could be exploited. The flaw could also be exploited if an attacker sends one of these files to the user as an email attachment, or even if a link is sent in an email. The parsing of the malformed file would be triggered.
Symantec reported that “Sufficiently malformed, the code executed at the kernel-level with system/root privileges causing a memory access violation.”
The critical Symantec vulnerability needs to be remediated as soon as possible. If you run Symantec anti-virus software and your system is not set to update automatically, it is essential to perform a manual Symantec LiveUpdate to address the issue. A patch is expected to be released in the next few days to address the other serious vulnerabilities discovered by Ormandy.
The 2012 LinkedIn data breach was believed to have resulted in the theft of 6.5 million emails and encrypted passwords; however, the data breach appears to be worse than previously thought with considerably more data stolen. Those data have now been listed for sale on a darknet marketplace, prompting LinkedIn to contact a substantial percentage of its users to get them to change their passwords.
117 Million Unsalted SHA-1 Hashes and Corresponding Usernames from 2012 LinkedIn Data Breach Listed for Sale
A hacker called “Peace” listed 117 million LinkedIn email and encrypted password combinations for sale this week. LinkedIn believes the data has also come from the 2012 LinkedIn data breach. The data were in the same format as the 6.5 million passwords and email combinations that were previously listed for sale. The latest batch of data has been listed or sale for a reported $2,200.
The passwords stolen in the 2012 LinkedIn data breach were unsalted SHA-1 hashes. While the passwords are encrypted, they are poorly protected and can easily be cracked with relative ease.
Soon after the 2012 LinkedIn data breach the 6.5 million account details were offered for sale on a Russian hacking forum. Motherboard reports that as many as 90% of those passwords were able to be cracked. This now places 18 times as many users at risk of having their accounts compromised.
LinkedIn users that joined the professional networking website after the 2012 data breach will not be affected by the data sale, although older users of the site could be at risk, especially if the password they used for their LinkedIn account has been used other logins elsewhere online.
Individuals who tend to use the same passwords on multiple websites or those who recycle old passwords are advised to change their passwords on their banking websites, social media profiles, email accounts, and other online sites if there is a possibility that they have used the same password as they used on LinkedIn prior to the 2012 breach.
The 2012 LinkedIn data breach was possible because security at the time was not particularly robust, although that has since been addressed. LinkedIn now salts its hashes, uses two factor authentication, and also email challenges. Since being alerted to the listing of the password/username combos, LinkedIn has been contacting affected users and attempting to invalidate passwords and force users to reset.
It is strongly advisable to login to LinkedIn and change your password as a precaution if you are unsure whether you have changed your password since 2012.
Each year, the Ponemon Institute conducts a benchmark survey on healthcare data privacy and security. The surveys give a picture of the state of healthcare data security, highlight the main threats faced by the healthcare industry, and offer an insight into the main causes of healthcare data breaches. This week, the Ponemon Institute released the results of its 6th annual benchmark study on healthcare data privacy and security.
Over the past 6 years, the main causes of healthcare data breaches have changed considerably. Back in 2010/2011 when the two healthcare data privacy and security surveys were conducted, the main causes of healthcare data breaches were lost and stolen devices, third party errors, and errors made by employees.
Breaches caused by the loss and theft of unencrypted devices such as laptops, smartphones, tablets, and portable storage devices such as zip drives has fallen considerably in recent years. Due to the high risk of loss and theft – and the cost of risk mitigation following a data breach and compliance fines – healthcare organizations are keeping tighter controls on portable devices. Staff have been trained to be more security conscious and many healthcare organizations have chosen to use data encryption on portable devices. However, lost/stolen devices and mistakes by employees and third parties are still the root cause of 50% of healthcare data breaches.
Healthcare Data Privacy and Security Study Shows Criminals Caused 50% of Healthcare Data Breaches
Data breaches caused by the loss and theft of portable devices may be in decline, but the same cannot be said of cyberattacks, which have increased considerably. When the first benchmarking study was conducted in 2010, 20% of data breaches were caused by hackers and other cybercriminals. By 2015, the figure had risen to 45%. This year criminals have been responsible for 50% of healthcare data breaches.
Healthcare data breaches have increased in volume, frequency, and severity. Prior to 2015, the largest healthcare data breach exposed 4.7 million patient health records. Data breaches that exposed more than 1 million healthcare records were very rare. However, in 2015, the Anthem Inc. breach exposed 78.8 million healthcare records, Premera BlueCross recorded a cyberattack that exposed 11 million records, and Excellus Blue Cross Blue Shield reported a breach of 10 million records. These data breaches were caused by criminals who gained access to systems using phishing techniques.
Phishing remains a major cause for concern, as is malware, although over the course of the past 12 months a new threat has emerged. Ransomware is now the second biggest cause for concern for healthcare security professionals. DDoS attacks remain the biggest worry as far as cyberattacks are concerned.
The purpose of ransomware and DDoS attacks is to cause widespread disruption. Healthcare IT professionals are right to be concerned. Both of these types of cyberattack have potential to have a hugely detrimental effect on the care that is provided to patients, potentially disrupting healthcare operations to such a degree that patients can actually come to physical harm.
Healthcare organizations have been investing more heavily in data security technologies to prevent breaches, yet these measures have not been sufficient to stop breaches from occurring. The report indicates that 89% of healthcare organizations suffered a data breach in the past two years, 79% suffered more than one breach, and 45% experienced more than five data breaches.
The cost of healthcare data breaches is considerable. The Ponemon Institute calculates the average cost to resolve a data breach to be $2.2 million for healthcare providers. The average cost of a business associate data breach is $1 million. The total cost each year, to mitigate risk and resolve data breaches, has been estimated by Ponemon to be $6.2 billion for the industry as a whole.
Healthcare Organizations Need to Increase Cybersecurity Efforts
Cybersecurity budgets may have increased over the years, but too little is being spent on healthcare data privacy and security data. Even with the increased risk, 10% of healthcare organizations have actually decreased their cybersecurity budgets, and more than half (52%) said their budgets have stayed the same this year.
Further investment is needed to tackle the growing threat and to prevent criminals from gaining access to data and locking it with ransomware.
Education also needs to be improved and greater care taken by healthcare employees to prevent accidental disclosures of data and mistakes that open the door to cybercriminals. Employee negligence was rated as the top cause for concern by both healthcare providers and business associates of healthcare organizations. Unless greater care is taken to prevent data breaches and healthcare organizations are held more accountable, the data breach totals will only rise.
The Federal Trade Commission (FTC) is conducting a study to investigate the security update practices of mobile device manufacturers. The study is being conducted amid concern that mobile device manufacturers are not doing enough to ensure owners of mobile devices are protected from security threats.
Security Update Practices of Mobile Device Manufacturers Leave Mobile Users Exposed to Attack
A number of new and highly serious threats have emerged in recent years which allow attackers to remotely execute malicious code on mobile devices if users visit a compromised website. One of the most serious threats comes from the Stagefright vulnerability discovered last year.
The Stagefright vulnerability could potentially be exploited to allow attackers to gain control of Android smartphones. It has been estimated that as many as one billion devices are prone to attack via this vulnerability. Google released an Android update to fix the vulnerability, yet many mobile phone users were unable to update their devices as the manufacturer of their device, or the mobile carrier they used, did not allow the updates to be installed. Because of this, many smartphone owners are still vulnerable to attack.
Even when device manufacturers do update their devices there are often long delays between the issuing of the fix and the rolling out of updates. When a rollout is executed, it can take a week or more before all device owners receive their updates. During that time users are left vulnerable to attack.
The FTC wants to find out more about the delays and the rationale behind the slow rolling out of updates.
FTC and FCC Join Forces and Demand Answers from Carriers and Device Manufacturers
The FTC has joined forces with the Federal Communications Commission (FCC) for the study and has ordered smartphone manufacturers and developers of mobile device operating systems to explain how security updates are issued, the reasoning behind the decision to delay the issuing of security updates, and for some device manufacturers, why security updates are not being issued.
While the study is primarily being conducted on manufacturers of devices running the Android platform, although Apple has also been ordered to take part in the study, even though its devices are the most secure. Apple’s security update practices are likely to serve as a benchmark against which other manufacturers will be judged. Manufacturers that use the Android platform that will take part in the study include Blackberry, HTC, LG, Motorola and Samsung. Google and Microsoft will also take part.
The FTC is asking operating system developers and mobile manufacturers to disclose the factors that are considered when deciding whether to issue updates to correct known vulnerabilities. They have been asked to provide detailed information on the devices they have sold since August 2013, if security vulnerabilities have been discovered that affect those devices, and if and when those vulnerabilities have been – or will be – patched.
The FCC has asked questions of mobile phone carriers including the length of time that devices will be supported, the timing and frequency of updates, the process used when developing security updates, and whether device owners were notified when the decision was taken not to issue a security update for a specific device model.
Whether the study will result in better security update practices of mobile device manufacturers remains to be seen, although the results of the study, if published in full, will certainly make for interesting reading.
Last week, the website of a major toy manufacturer was discovered to have been compromised and was being used to infect visitors with ransomware. The website of Maisto was loaded with the Angler exploit kit that probed visitors’ browsers for exploitable vulnerabilities. When vulnerabilities were discovered, they were exploited and ransomware was downloaded onto visitors’ devices. In this case, the ransomware used was CryptXXX.
Many ransomware infections require a system rebuild and restoration of data from a backup. If a viable backup does not exist there is no alternative but to pat the attackers for an encryption. Fortunately, in this case there is an easy fix for a CryptXXX infection. The ransomware-encrypted files can be decrypted for free according to Kaspersky Lab. However, there are many malicious strains of ransomware that are not so easy to remove.
While decrypting files locked by CryptXXX is possible, that is not the only malicious action performed by the ransomware. CryptXXX is also an information stealer and can record logins to FTP clients, email clients, and steal other data stored in browsers. It can even steal bitcoins from local wallets.
CryptXXX is now being used in at least two major exploit kit attack campaigns according to researchers from Palo Alto Networks. While Locky ransomware was extensively used in March this year – deployed using the Nuclear exploit kit – the attackers appear to have switched to the Angler exploit kit and the Bedep/CryptXXX combo.
How to Block Exploit Kits from Downloading Malware
To protect end users’ devices and networks from malware downloads and to block exploit kits, system administrators must ensure that all browser plugins are kept up to date. Exploit kits take advantage in security vulnerabilities in a wide range of plugins, although commonly vulnerabilities in Flash and Java are exploited. These two browser plugins are used on millions of machines, and new zero-day vulnerabilities are frequently discovered in both platforms. Cybercriminals are quick to take advantage. As soon as a new vulnerability is identified it is rapidly added to exploit kits. Any machine that contains an out-of-date plug in is at risk of attack.
It takes time for patches to be developed and released when a new zero-day vulnerability is discovered. Keeping all devices up to date is a time consuming process and sys admins are unlikely to be able to update all devices the second a patch is released. To effectively protect devices and networks from attacks using exploit kits, consider using a web filtering solution.
A web filter can be used to block websites containing exploit kits and thus prevent the downloading of malware, even if patches have not been installed. The best way to block exploit kits from downloading malware is to ensure that end users never visit a website containing an exploit kit!
A web filter should not be an excuse for poor patch management practices, but web filtering software can ensure devices and networks are much better protected.

New Revenue Avenues for MSPs: Internet Filtering-as-a-Service
The benefits of WebTitan Cloud are considerable. Our web filtering solution can be used to protect virtually all organizations from a wide range of Internet threats: Something that is increasingly important given the increase in phishing attacks and the proliferation of malware and ransomware in recent years. The cost of resolving malware infections is considerable, and data theft and loss can have catastrophic consequences for SMBs. Heavy fines can be issued by regulators for data breaches, and reputation damage from customer data theft can be considerable.
Employees need to be provided with Internet access to work efficiently; however, Internet access is often abused. Employees are wasting a considerable amount of time each day on personal Internet use. Social media networks are accessed, gambling sites used at work, and gaming sites used by many employees during working hours. By limiting access to these websites organizations can greatly increase the productivity of the workforce. Filtering the Internet to prevent employees and customers from accessing inappropriate website content can also prevent HR issues from developing and can reduce legal risk.
Our web filtering solution can also be used to manage bandwidth. Most organizations face bandwidth issues at some point, yet with careful configuration of our web filter, bandwidth can be effectively managed. Bandwidth-heavy Internet services can be limited to ensure that fast Internet access can be enjoyed by all.

The risk of phishing attacks has increased considerably over the past 12 months, according to a new data breach report from Verizon. Ransomware attacks are also on the rise. The two are often used together to devastating effect as part of a three-pronged attack on organizations.
Firstly, cybercriminals target individual employees with a well-crafted phishing campaign. The target is encouraged to click a link contained in a phishing email which directs the soon-to-be victim to a malicious website. Malware is then silently downloaded to the victim’s device.
The malware logs keystrokes to gain access to login credentials which allows an attacker to infiltrate email accounts and other systems. Infections are moved laterally to compromise other networked devices. Stolen login credentials are then used to launch further attacks, which may involve making fraudulent bank transfers or installing ransomware on the network.
The Risk of Phishing Attacks is Growing
Verizon reports that due to the effectiveness of phishing and the speed at which attackers are able to gain access to networks, the popularity of the technique has grown substantially. In years gone by, phishing was a technique often used in nation-state sponsored attacks on organizations. Now there is a high risk of phishing attacks from any number of different players. Even low skilled hackers are now using phishing to gain access to networks, steal data, and install malware. Out of the nine different incident patterns identified by the researchers, phishing is now being used in seven.
Phishing campaigns are also surprisingly effective. Even though many companies now provide anti-phishing training, attempts to educate the workforce to minimize the risk of phishing attacks is not always effective. The 2016 Verizon data breach report suggests that when phishing emails are delivered to inboxes, 30% of end users open the emails. In 2015 the figure was just 23%. Rather than employees getting better at identifying phishing emails they appear to be getting worse. Even worse news for employers is 13% of individuals who open phishing emails also double click on attached files or visit the links contained in the emails.
Ransomware Attacks Increased 16% in a Year
Ransomware has been around for the best part of a decade although criminals have favored other methods of attacking organizations. However, over the past couple of years that has changed and the last 12 months has seen a significant increase in ransomware attacks on businesses. According to the data breach report, attacks have increased by 16% in the past year. As long as companies pay attackers’ ransom demands attacks are likely to continue to increase.
How Can Web Filtering Software Prevent Ransomware Infections and Reduce the Risk of Phishing Attacks
Defending a network from attack requires a wide range of cybersecurity defenses to be put in place. One of the most important defenses is the use of web filtering software. A web filter sits between end users and the Internet and controls the actions that can be taken by end users as well as the web content they are allowed to access.
A web filter can be used to block phishing websites and malicious sites where drive-by malware downloads take place. Web filtering software can also be configured to block the downloading of files typically associated with malware.
Training employees how to avoid phishing emails can be an effective measure to reduce the risk of phishing attacks, but it will not prevent 100% of attacks, 100% of the time. When training is provided and web filtering software is used, organizations can effectively manage phishing risk and prevent malware and ransomware infections. As phishing attacks and ransomware infections are on the increase, now is the ideal time to start using web filtering software.
The recent rise in ransomware infections has been attributed to the proliferation of ransomware-as-a-service, with many malicious actors now getting in on the act and sending out spam email campaigns to unsuspecting users.
Ransomware-as-a-Service Proliferation is a Major Cause for Concern
The problem with ransomware-as-a-service is how easy it is for attackers with relatively little technical skill to pull off successful ransomware attacks. All that is needed is the ability to send spam emails and a small investment of capital to rent the ransomware. The malicious software is now being openly sold as a service on underground forums and offered to spammers under a standard affiliate model.
The malware author charges a nominal fee to rent out the ransomware, but takes a large payment on the back end. Providers of ransomware-as-a-service typically take a cut of 5%-25% of each ransom. Spammers get to keep the rest. Renters of the malicious software cannot access the source code, but they can set their own parameters such as the payment amount and timescale for paying up.
SMBs Increasingly Targeted by Attackers
While individuals were targeted heavily in the past and sent ransom demands of around $400 to $500 to unlock their family photographs and other important files, attackers and now extensively targeting businesses. Often the same model is used with a fee charged by the attackers per install.
When an organization has multiple devices infected with ransomware the cost of remediation is considerable. One only needs to look to Hollywood Presbyterian Medical Center to see how expensive these attacks can be. The medical center was forced to pay a ransom of $17,000 to unlock computers infected with ransomware, in addition to many man-hours resoling the infection once the encryption keys had been supplied. Not to mention the cost of reputation damage and clearing the backlog due to the shutting down of its computers for over a week.
Warning Issued About the Insider Ransomware Threat
As if the threat from ransomware was not enough, researchers believe the situation is about to get a whole lot worse. Ransomware-as-a-service could be used by a malicious insider to infect their own organization. With insider knowledge of the locations and types of data critical to the running of the business, an insider would be in the best position to infect computers.
Insiders may also be aware of the value of the data and the cost to the business of losing data access. Ransoms could then be set accordingly. With payments of tens of thousands of dollars possible, this may be enough to convince some employees to conduct insider attacks. Since finding hackers offering ransomware-as-a-service is not difficult, and network access has already been gained, insiders may be tempted to pull off attacks.
To counter the risk of insider ransomware attacks businesses should develop policies to make it crystal clear to employees that attackers will be punished to the full extent of the law. Software solutions should be put in place to continuously monitor for foreign programs installed on networks and network privileges should be restricted as far as is possible. Employees should have their network activities monitored and suspicious activity should be flagged and investigated. It is not possible to eliminate the risk of insider attacks, but it is possible to reduce risk to a minimal level.
