Data Breach News
Our data breach news items reinforce the need for organizations to maximize their defenses against malware attacks and phishing campaigns. Even though online security awareness is at an all-time high, cybercriminals are becoming more sophisticated in the methods used to extract passwords and break into databases.
It is also apparent from reading our data breach news items that the volume of cyberattacks is increasing. In order to mitigate the risk of malware attacks, organizations should implement a web content filter, while an email filter to prevent spams and scams reaching an inbox can eliminate the risk from phishing campaigns completely. Speak with us today for more information.
A massive global cyberattack is underway involving Petya ransomware. Ukraine has been hit particularly hard although companies all over Europe have reported that systems have been taken out of action and ransoms demanded. Social media websites are awash with reports of disruption to services across a wide range of industries and countries. The attacks appear to have started in Russia/Ukraine but spread rapidly across Europe, with reports emerging that companies in India have also been affected.
The attacks appear to involve a variant of Petya ransomware – a particularly nasty ransomware variant for which there is no kill switch or free decryptor. Petya ransomware takes the Master File Table (MFT) out of action rather than encrypting individual files. Consequently, the attacks occur faster than with other ransomware variants. Without access to the MFT, computers are unable to locate files stored on the hard drive. Those files remain unencrypted, but cannot be accessed.
The ransom demand to unlock the infection is understood to be approximately $300, although that figure will need to be multiplied by the number of devices affected.
Another WannaCry Style Global Ransomware Attack
The WannaCry ransomware attacks used exploits stolen from the NSA, which were published online by Shadow Brokers. Those exploits worked on unpatched systems, exploiting vulnerabilities to automatically download a network worm and WannaCry ransomware. The attacks spread rapidly – around the world and within organizations.
This wave of attacks appears to be similar. The attacks started happening this morning with the Russian cybersecurity firm Group-IB one of the first to suggest this was a WannaCry-style attack involving an NSA exploit. That has since been confirmed by other cybersecurity firms. Fabian Wosar of Emisoft said he has confirmed that the infection is spreading using the same EternalBlue exploit as WannaCry, as has MalwareHunterTeam.
Organizations that applied the patch issued by Microsoft in March were protected from WannaCry and will likely be protected from this Petya ransomware attack. Following WannaCry, Microsoft issued patches for unsupported operating systems to prevent further attacks from occurring. However, judging by the number of attacks that have already occurred, the WannaCry attacks did not spur some companies into action. Many have still not patched their systems.
Several well-known companies have reported they are under attack and have had servers and computers taken out of action, with companies in Russia, Ukraine, France, Spain, Denmark, India and the UK all understood to have been affected. Companies that have confirmed they have been attacked include:
Russia – Oil company Rosneft and metal maker Evraz
Ukraine – Boryspil Airport, aircraft manufacturer Antonov, two postal services, the Ukraine government, the Ukraine national bank. The Cernobyl nuclear powe plant has also been attacked, as have many other energy companies in the country.
Denmark – Shipping firm A.P. Moller-Maersk, including APM Terminals which runs shipping container ports around the world.
France – Construction firm Saint Gobain
International – Companies reportedly affected include the law firm DLA Piper, advertising firm WPP, food manufacturer Mondalez and U.S pharmaceutical firm Merck.
Time will tell whether this Petya ransomware attack will be on a similar scale to WannaCry. Since it is currently occurring it will likely be a few days before the true scale of the attack becomes known.
For the first time in the past seven years, the cost of a data breach has fallen, with a 10% reduction in per capita data breach costs across all industry sectors. The global study revealed the average cost of a data breach is now $141 per exposed or stolen record. The global average cost of a data breach is down to $3.62 million from $4 million last year.
The IBM Security sponsored study was conducted by the Ponemon Institute, which has been tracking the costs of data breaches for the past seven years. In every other year data breach costs have risen year over year.
The Ponemon Institute say the reduction can partly be explained by a strong dollar. In the United States, the cost of a data breach has risen from $221 to $225 per record with the total breach cost increasing to $7.35 million from $7.02 million last year.
For the study, the Ponemon Institute assessed the breach resolution costs after organizations experienced a breach and had notified affected individuals. Large data breaches – those in which more than 100,000 records were exposed or stolen – were not included in the study as they were deemed atypical. Instead, only breaches of between 5,000 and 100,000 records were included. The average size of the breaches were 28,512 records. A breach was defined as the loss or theft of a record that included an individual’s name along with either their Social Security number, financial information or medical record.
For the seventh consecutive year, the healthcare industry had the highest data breach costs. The per capita cost of a healthcare data breach was $380. The financial services, another highly regulated industry, had the second highest breach costs ($336 per record). Services sector data breaches cost $274 per record, life sciences breaches were $264 per record and the Industrial sector had a per capita breach cost of $259.
The lowest breach costs were retail ($177), hospitality ($144), entertainment ($131), research ($123) and the public sector ($110). The biggest cause of data breaches were malicious and criminal attacks, which also carried the highest resolution costs. System glitches and human error each accounted for 24% of data breaches.
An analysis of breach costs revealed there are a number of ways to reduce the cost of a data breach. Having a breach response plan in place saw companies reduce breach costs by $19 per record, while the use of encryption reduced breach costs by an average of $17 per record. Employee education helped reduce breach costs by an average of $12.50 per record.
A fast response to a data breach can also dramatically reduce the total breach cost. Organizations that were able to contain a breach within 30 days saw breach costs reduced by $1 million. On average, it takes companies more than six months to discover a breach and containing the breach takes an average of 66 days.
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.
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.
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.

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.
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.
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 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.

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.
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.

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.
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.

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.
