Business email compromise (BEC) attacks cost businesses billions of dollars each year, and business email account compromises are soaring.
What is a Business Email Compromise Attack?
As the name suggests, these attacks involve the hijacking of business email accounts. The primary aim is to compromise the account of the CEO or CFO, which is usually achieved through a spear phishing attack. Once the email account has been compromised, it is used to send phishing emails to other employees in the company, most commonly, employees in the accounts, finance, and payroll departments.
The emails commonly request wire transfers be made to accounts under the control of the attackers. Requests are also made for sensitive information such as the W-2 Forms of employees.
Since the emails are sent from the CEO or CFO’s own account, there is a much higher chance of an employee responding to the request than to a standard phishing attempt from an external email address. Since the emails come from within an organization, they are also much harder to detect as malicious – a fact not lost on the scammers.
With access to the email account, it is much easier to craft convincing messages. The signature of the CEO can be copied along with their style of writing from sent messages. Email conversations can be started with employees and messages can be exchanged without the knowledge of the account holder.
Fraudulent transfers of tens or hundreds of thousands of dollars may be made and the W-2 Forms of the entire workforce can be obtained. The latter can be used to submit fake tax returns in victims’ names to obtain tax refunds. The profits for the attackers can be considerable, and with the potential for a massive payout, it is no surprise that these attacks are on the rise.
Business Email Account Compromises Have Increased by 284% in a Year
FBI figures in December 2016 suggest $5.3 billion had been lost to BEC scams since October 2013. That figure had now increased to $12.5 billion. More than 30,000 complaints of losses due to BEC attacks were reported to the FBI’s Internet Crime Complaints Center (IC3) between June 2016 and May 2018.
The specialist insurance service provider Beazley has been tracking business email account compromises. The firm’s figures show business email account compromises have increased each quarter since Q1, 2017. In the first quarter of 2017, 45 business email account compromises were detected. In Q2, 2018, 184 business email account compromises were detected. Between 2017 to 2018, there was a 284% increase in compromised business email accounts.
While the CEO’s email credentials are often sought, the credentials of lowlier employees are also valuable. Any email account credentials that can be obtained can be used for malicious purposes. Email accounts can be used to send phishing messages to other individuals in an organization, and to business contacts, vendors, and customers.
Beazley notes that once one account has been compromised, others will soon follow. When investigating business email account compromises, businesses often discover that multiple accounts have been compromised. Typically, a company is only aware of half the number of its compromised accounts.
The High Cost of Resolving Business Email Account Compromises
Business email account compromises can be extremely costly to resolve. Forensic investigators often need to be brought in to determine the full extent of the breach. Each breached email account must then be checked to determine what information has been compromised. While automated searches can be performed, manual checks are inevitable. For one client, the automated search revealed 350,000 document attachments had potentially been accessed, and each of those documents had to be checked manually to determine the information IT contained. The manual search alone cost the company $800,000.
How to Protect Your Organization from Business Email Compromise Attacks
A range of measures are required to protect against business email compromise attacks. An advanced spam and anti-phishing solution is required to prevent phishing and spear phishing emails from being delivered to inboxes.
SpamTitan is an easy-to-implement spam filtering solution that blocks advanced phishing and spear phishing attacks at source. In contrast to basic email filters, such as those incorporated into Office 365, SpamTitan uses heuristics, Bayesian analysis, and machine learning to identify highly sophisticated phishing attacks and new phishing tactics. These advanced techniques ensure more than 99.9% of spam and malicious messages are blocked.
The importance of security awareness training should not be underestimated. End users should be trained how to recognize phishing attempts. Training should be ongoing to ensure employees are made aware of current campaigns and new phishing tactics. Phishing simulation exercises should also be conducted to reinforce training and identify weak links.
Multi-factor authentication is important to prevent third parties from using stolen credentials to access accounts. If a login attempt is made from an unfamiliar location or unknown device, an additional form of identification is required to access the account.
Password policies should be enforced to ensure that employees set strong passwords or passphrases. This will reduce the potential for brute force and dictionary attacks. If Office 365 is used, connection to third party applications should be limited to make it harder for PowerShell to be used to access email accounts. A web filtering solution should also be implemented to block access to phishing accounts where email credentials are typically obtained.
Defense in depth is the key to protecting against BEC attacks. For more information about email and web security controls to block BEC attacks, give the TitanHQ team a call.

WiFi networks are a potential security weak point for businesses, although the introduction of WPA3 will improve Wi-Fi security. WPA3 Wi-Fi security enhancements address many WP2 vulnerabilities, but WPA3 alone is not enough to block all WiFi threats.
WiFi Security Protocols
The WPA WiFi security protocol was introduced in 1999, and while it improved security, cracking WPA security is far from difficult. Security enhancements were introduced with WPA2 in 2004, but while more secure, WPA2 does not fix all vulnerabilities. Little has changed in the past 14 years, but at long last, WPA3 is here. Use WPA3 and Wi-Fi security will be significantly enhanced, as several important WP2 vulnerabilities have been fixed.
WPA3 WiFi Security Enhancements
One of the biggest WiFi security threats is open networks. These are WiFi networks that require no passwords or keys. Users can connect without entering a pre-shared key. All a user needs to know is the SSID of the access point to connect. These open networks are used in establishments such as coffee shops, hotels, and restaurants as it is easy for customers to connect. The problem is users send plain text to the access point, which can easily be intercepted.
WPA3 spells an end to open networks. WPA3 uses Opportunistic Wireless Encryption (OWE). Any network that does not require a password, will encrypt data without any user interaction or configuration. This is achieved through Individualized Data Protection or IDP. Any device that attempts to connect to the access point receives its own key from the access point, even if no connection to the AP has been made before. This control means the key cannot be sniffed and even if a password is required, having access to that password does not allow the data of other users to be accessed.
Another security enhancement that has been made in WP3 reduces potential for password cracking attacks such as the WPA2 KRACK Attack. WPA2 is vulnerable to brute force and dictionary-based attacks. That is because security relies on the AP provider setting a secure password and many establishments don’t. With WPA3, the Pre-Shared Key (PSK) exchange protocol is replaced with Simultaneous Authentication of Equals (SAE) or the Dragonfly Key Exchange, which improves security of the initial key exchange and offers better protection against offline dictionary-based attacks.
WPA3 also addresses security vulnerabilities in the WiFi Protected Setup (WPS) that made it easy to link new devices such as a WiFi extender. In WPA3, this has been replaced with Wi-Fi Device Provisioning Protocol (DPP).
Configuring IoT devices that lack displays has been made easier, the 192-bit Commercial National Security Algorithm is used for enhanced protection for government, defense and industrial networks, and better controls have been implemented against brute force attacks. These and other enhancements mean WPA3 is far more secure.
Unfortunately, at present, very few manufacturers support WPA3, although that is likely to change in 2019.
WPA3 WiFi Security Issues
Even with WPA3 WiFi security enhancements, WiFi networks will still be vulnerable. WPA3 includes encryption for non-password-protected networks, but it does not require authentication. That is up to hotspot providers to set. WPA3 it is just as susceptible to man-in-the-middle attacks and offers no protection against evil twin attacks. The user must ensure they access the genuine access point SSID.
The connection to the AP may be more secure, but WPA3 does not offer protection against malware downloads. Users will still be at risk from malicious websites unless a DNS filtering solution is used – A web filter to protect WiFi networks.
Improve WiFi Security with a DNS-Based WiFi Filtering Solution
A DNS-based WiFi filtering solution such as WebTitan Cloud for WiFi protects users of a WiFi network from malware attacks, ransomware downloads, and phishing threats. The cloud-based filter also allows businesses that provide WiFi access points to carefully control the content that can be accessed by employees, customers, and other guest users.
By upgrading to WPA3 WiFi security will be improved. With WebTitan Cloud for WiFi, users will also be protected once they are connected to the network.
Further information on WebTitan Cloud for WiFi is detailed in the video below. For further information on WiFi security, including WebTitan pricing and to book a product demonstration, contact the TitanHQ team today.
Many employees access their work emails and work networks via public Wi-Fi hotspots, even though there is a risk that sensitive information such as login credentials could be intercepted by hackers. Many employees are unaware of the Wi-Fi security threats that lurk in their favorite coffee shop and fail to take precautions. Even employees who are aware of the Wi-Fi security threats often ignore the risks.
This was highlighted by a 2017 survey by Symantec. 55% of survey participants said they would not hesitate to connect to a free Wi-Fi hotspot if the signal was good and 46% said they would rather connect to a free, open wireless network than to wait to get a password to a secure access point.
60% of survey participants believed public Wi-Fi networks are safe and secure but even though 40% are aware of the Wi-Fi security threats, 87% said that they would access financial information such as their online banking portal or view their emails on public Wi-Fi networks.
The majority of users of public Wi-Fi networks who were aware of the Wi-Fi security threats said they ignored the risks. Millennials were the most likely age group to ignore Wi-Fi security threats: 95% of this age group said they had shared sensitive information over open Wi-Fi connections.
Consumers may be willing to take risks on public Wi-Fi networks, but what about employees? According to a 2018 Spiceworks survey, conducted on 500 IT professionals in the United States, employees are also taking risks.
61% of respondents to the survey said their employees connect to public Wi-Fi hotspots in coffee shops, hotels, and airports to work remotely. Only 64% of respondents said their employees were aware of the Wi-Fi security threats. A similar percentage said their employees were aware of the risks and connect to their work networks using a VPN, which means that 4 out of 10 workers were unaware of the importance of establishing a secure connection.
Even though 64% of respondents were confident that employees were aware of the risks, only half were confident that data stored on mobile devices was adequately protected against threats from public Wi-Fi hotspots. 12% of respondents said they have had to deal with a public Wi-Fi related security incident, although a further 34% were not sure if there had been a security breach as many incidents are never reported.
WiFi Security Threats Everyone Should be Aware of
All employers should now be providing security awareness training to their employees to make the workforce more security aware. Employees should be trained how to identify phishing attempts, warned of the risk from malware and ransomware, and taught about the risks associated with public Wi-Fi networks.
Five threats associated with open public Wi-Fi hotspots are detailed below:
Evil Twins – Rogue Wi-Fi Hotspots
One of the most common ways of obtaining sensitive information is for a cybercriminal to set up an evil twin hotspot. This is a fake Wi-Fi access point that masquerades as the legitimate access point, such as one offered by a coffee shop or hotel. An SSID could be set up such as “Starbuck Guest Wi-Fi” or even just state the name of the establishment. Any information disclosed while connected to that hotspot can be intercepted.
Using a packet sniffer, a hacker can identify, intercept, and monitor web traffic over unsecured Wi-Fi networks and capture personal information such as login credentials to bank accounts and corporate email accounts. If credentials are obtained, a hacker can gain full control of an account.
Many people have file-sharing enabled on their devices. This feature is useful at home and in the workplace, but it can easily be abused by hackers. It gives them an easy way to connect to a device that is connected to a Wi-Fi hotspot. A hacker can abuse this feature to drop malware on a device when it connects to a hotspot.
Not all threats are hi-tec. One of the simplest methods of obtaining sensitive information is to observe someone’s online activities by looking over their shoulder. Information such as passwords may be masked so the information is not visible on a screen, but cybercriminals can look at keyboards and work out the passwords when they are typed.
Malware and Ransomware
When connecting to a home or work network, some form of anti-malware control is likely to have been installed, but those protections are often lacking on public Wi-Fi hotspots. Without the protection of AV software and a web filter, malware can be silently downloaded.
Employers can reduce risk by providing comprehensive training to employees to make sure they are aware of the risks from public Wi-Fi hotspots and make sure that employees are aware they should only connect to public Wi-Fi networks if they use a VPN. Employers can further protect workers with WebTitan Cloud – An enterprise-class web filter that protects workers from online threats, regardless of where they connect.
Hotspot providers can protect their customers by securing their Wi-Fi hotspots with WebTitan Cloud for Wi-Fi. WebTitan Cloud for Wi-Fi is a powerful web filter that protects all users of a hotspot from malware and phishing attacks, and can also be used to control the types of sites that can be accessed. If you offer Wi-Fi access, yet are not securing your hotspot, your customers could be at risk. Contact TitanHQ today to find out how you can protect your customers from online threats, control the content that can be accessed, and create a family-friendly Wi-Fi environment.
In this post we explain the importance of WiFi filtering and brand protection. It can take years of hard work for businesses to develop trust in their brand. That trust can easily be lost if customers are not protected while connected to business WiFi networks and come to harm or suffer losses.
If Trust is Lost in a Brand it Can Take Years to Recover
Trust is a cornerstone of all successful brands, but it is not something that can be developed overnight. Developing trust in a brand takes an extraordinary amount of time and money, but once established, companies will be rewarded by customer loyalty.
While trust can be difficult to earn, it is certainly not difficult to lose. One of the easiest ways for consumers to lose trust in a brand is through privacy breaches and cyberattacks. If the personal data of customers is exposed or stolen, customers will lose faith in the brand and are likely to take their business elsewhere.
A 2017 study by Gemalto revealed 70% of customers would stop doing business with a company that failed to protect their personal data and suffered a data breach. Regaining customers trust after a data breach can take years. Protecting customer data is therefore essential if a business is to succeed and continue to enjoy success.
Wi-Fi Security and Brand Protection
One aspect of security that is often overlooked is protecting customers who connect to Wi-Fi networks. Many businesses offer free Wi-Fi access to their customers yet fail to implement controls over what customers can do while connected. Consequently, customers may be exposed to malware, phishing, and other harmful content.
Even businesses that claim to be family friendly often do not always filter the Internet and block access to adult and other age-inappropriate web content. It was only relatively recently that McDonald’s started filtering its WiFi networks to protect customers. Starbucks has also agreed to implement WiFi filters to block porn next year.
How are Wi-Fi filtering and brand protection related? Imagine someone uses your WiFi network to access pornography and a child views their screen? Or a parent finds out their child has been viewing adult content on the establishment’s Wi-Fi network? It only takes one person to complain via a social media network for the story to go viral and for the company’s reputation to be tarnished. The same goes for a malware infection as a result of an establishment failing to implement anti-malware controls on its WiFi network.
Implementing a WiFi filter shows customers that you are doing all you can to protect them from online threats and harmful content. WiFi security is therefore important for brand protection.
There have also been cases of businesses temporarily losing Internet access over illegal Internet activity – Employees who have used a corporate WiFi network to engage in illegal activities such as downloading pirated content. ISPs can terminate internet access if complaints are received and loss of Internet access can cripple a business. Legal action can also be taken by the copyright holder against the business.

A new phishing campaign is bypassing Office 365 anti-phishing defenses and arriving in employees’ inboxes; one of several recent campaigns to slip through the net and test end users’ security awareness knowledge.
The aim of this campaign is not to obtain login credentials or install malware. It is a sextortion scam that aims to get email recipients to make a payment to the scammers.
The scam itself is straightforward. The sender of the email claims to be a hacker who has gained access to the victim’s computer and has installed malware. That malware allowed full access to the user’s device, including control of the webcam. The email claims that the webcam was used to record the victim while he/she was accessing adult web content. The attacker claims to have spliced the webcam recording with the images/videos that were being viewed at the time. The attacker claims the video will be sent to the user’s contacts on social media and via email.
Several similar sextortion scams have been conducted in the past few months, but what makes this campaign different is the extent of the deception. In this campaign, the attacker includes the user’s password in the email body.
I’m a hacker who cracked your email and device a few months ago.
You entered a password on one of the sites you visited, and I intercepted it.
This is your password from [user’s email]on moment of hack: [user’s password]”
The password may not be the one currently used, but it is likely to be recognized as it has been taken from a previous data breach. However, its inclusion will be especially worrying for any user who does not regularly change their password and for users that share passwords across multiple sites or reuse old passwords. Changing the password will not block access, according to the email
“Of course, you can and will change it, or already have changed it.
But it doesn’t matter, my malware updated it every time.”
For anyone who has viewed adult content on a laptop or other device with a webcam, this message will no doubt be extremely concerning. Especially, as the email contains ‘evidence’ of email compromise. The From field of the email displays the user’s own email address, indicating that the attacker has sent it from the user’s email account.
The attacker notes in the email, “Do not try to contact me or find me, it is impossible, since I sent you an email from your account.”
While scary, the attacker does not have access to the user’s email account. The From field has been spoofed. This is actually straightforward with a Unix computer set up with mail services. Mass emails can be sent out using the same email address in the From field as the Address field, giving the impression that the messages have been sent from the users’ accounts.
The hacker notes that this is not his/her usual modus operandi. “You are not my only victim, I usually lock computers and ask for a ransom. But I was struck by the sites of intimate content that you often visit.” That will be a particular worry for some users.
To prevent distribution of the video, the user must pay $892 in Bitcoin to the specified address and many email recipients have chosen to pay to avoid exposure. The Bitcoin wallet used for the scam has received 450 payments totaling 6.31131431 BTC – around $27,980. Multiple Bitcoin wallets are often used by scammers, so the actual total is likely to be far higher.
Bypassing of Office 365 Anti-Phishing Defenses a Cause for Concern
This scam may not have any direct impact on a business, as no credentials are compromised, and malware is not installed; however, what is of concern is how the messages have bypassed Office 365 phishing defenses and are arriving in inboxes. The scam was first identified in late September and the messages continued to be delivered to Office 365 inboxes, even those with Advanced Threat Protection that companies pay extra for to provide greater protection against spam and phishing emails.
This is of course just one scam. Others have similarly breached Office 365 anti-phishing defenses, many of which are much more malicious in nature and pose a very real and direct threat to businesses. Office 365 anti-phishing protections do block a lot of threats, and protection is improved with Advanced Threat Protection, but the controls are not particularly effective at blocking sophisticated phishing attempts and zero-day attacks.
The volume of phishing attacks on businesses that are now being conducted, the sophisticated nature of those attacks, and the high cost of mitigating a phishing attack and data breach mean businesses need to improve Office 365 anti-phishing defenses further. That requires a third-party spam solution.
For more than 20 years, TitanHQ has been developing security solutions to protect inboxes and block web-based attacks. During that time, our spam filtering solution, SpamTitan, has been gathering threat intelligence, analyzing spamming and phishing tactics, and protecting end users. Over the years, SpamTitan has receive many updates to improve protection against new threats and phishing tactics. Independent tests have shown SpamTitan now has a catch rate in excess of 99.9%.
The incorporation of a range of predictive techniques ensure SpamTitan is not reliant on signatures and can detect never-before seen phishing attempts and zero-day attacks, and provide superior protection against spam, phishing, malware, viruses, ransomware, and botnets for Office 365 users.

If you are using Umbrella and are finding the web filtering solution to be a drain of your time or your budget, consider making the switch from Umbrella to WebTitan.
Web Filtering Doesn’t Have to be Complicated
There are many factors that need to be considered when choosing a web filtering solution. Aside from allowing you to identify and block threats and control the content that can be accessed by network users, a web filter should be easy to configure and maintain.
To get the most benefit from your chosen solution, you will need to have all the information you need at your fingertips. You should be able to tweak settings, block/unblock sites, and get the reports you need on users that are attempting to, or succeeding in, accessing dangerous web content.
All too often, it is only when the solution is set up that the discovery is made that it is a pig to use. The information you need is not easily accessible and maintaining and managing the solution is headache inducing. However, it needn’t be that way.
Usability is one area where WebTitan excels. WebTitan is powerful, feature rich, yet simple to use. WebTitan can be used by anyone, regardless of their level of IT knowhow. The user interface is crisp, clean, and provides all the important information in one place.
Complex interfaces mean more time is spent making minor changes and accessing reports, which takes time away from more important tasks. Further, if Your IT team hates using a solution, they will spend as little time as possible using it, and that could jeopardize security.
That is exactly what was happening with Saint Joseph Seminary College, which, after experiencing problems, made the switch from Cisco Umbrella to WebTitan.
Benefits of Switching from Umbrella to WebTitan: A Case Study
Web filter usability was a key issue for Saint Joseph Seminary College, which had been using Cisco Umbrella to control the web content staff and students could access. While Umbrella did allow content controls to be applied, using the solution was time consuming and difficult. Finding information, generating reports, and changing settings was just taking too much time. So much time that IT department avoided using the solution as far as possible. Hardly an ideal situation for such an important college cybersecurity control.
“I prefer an interface to be simple while giving me as much information as possible in one place. I don’t need rounded corners and elegant fonts when I am trying to see who has been visiting dangerous websites. I need to clearly see domain names and internal IPs,” explained Saint Joseph’s IT Director, Todd Russell. Russell went on to explain that it wasn’t always that way. “In my opinion, after Cisco bought OpenDNS, they made some major changes to the UI which made it virtually useless for quickly looking through blocked traffic for signs of particular types of usage.”
This is sadly a common problem. In an attempt to cram in as many features as possible into a user interface, too little consideration is given to the people that have to use and manage the solution. For busy IT departments, it is important to make things as simple as possible. Sysadmins have more than their fair share of complexity as it is.
It was the complexity of Umbrella – and the cost – that led Saint Joseph’s to see an Umbrella alternative.
An Easy to Use, More Cost-Effective Alternative to Umbrella
When looking for an Umbrella alternative, several solutions were considered; however, TitanHQ’s feature-rich web filter, WebTitan, stood out from the crowd and warranted closer inspection.
“It didn’t take long to realize that WebTitan was the best alternative for an efficient, cost-effective, and easy to use filtering solution to replace Cisco Umbrella,” explained Russell.
WebTitan has been developed with usability at the heart of the design process. Before UI changes are made, they are extensively tested to make sure they do not negatively impact the user experience.
After switching from Umbrella to WebTitan, the benefit was immediately gained. The IT department had easy access to actionable insights into threat traffic and web activity. Reports could be generated and viewed with two clicks of the mouse, The IT department liked using the solution, and further, an enormous amount of time was saved, and costs were slashed.
“WebTitan immediately gave us visibility into our users’ traffic. Within days, the UI allowed us to see clear signals of dangerous activity. Thanks to the easily accessible and understandable data available on the WebTitan UI, we have been able to launch investigations more quickly and work on remediation.” Said Russell. “The whole experience with WebTitan has been terrific.”
Benefits Gained from the Switch from Umbrella to WebTitan
By changing from Umbrella to WebTitan, Saint Joseph’s was able to:
Have easy access to actionable insights on threats and web activity
Remediate issues far more quickly
Quickly generate basic and advanced reports
Secure data and users more effectively
Slash administration and remediation time
Reduce the cost of web security by 50%
Block thousands more threats per hour

Why is DNS filtering for MSPs so important? Find out how you can better protect your clients against web-based attacks and the MSP benefits of offering this easy to implement cybersecurity solution.
A recent survey conducted by Spiceworks has revealed that DNS filtering is now considered an essential part of the security stack at the majority of large firms. The survey was conducted on companies with more than 1,000 employees and revealed 90% of those firms are using a solution such as a DNS filter to restrict access to the internet to provide protection from malware and ransomware attacks.
89% of firms use DNS filters or other web filtering technology to improve productivity by blocking access to sites such as social media platforms, 84% of firms block access to inappropriate websites, and 66% use the technology to avoid legal issues.
Given the risk of a malware or ransomware download over the Internet and the high cost of mitigating such an attack, it is no surprise that so many large firms are using web filtering technology to reduce risk.
Why DNS Filtering is so Important for SMBs
Phishing attacks and ransomware/malware downloads are major risks for large businesses, but SMBs face the same threats. SMBs are also less likely to have the resources to cover the cost of such an attack. For example, the average cost of a ransomware attack on an SMB is $46,800 according to Datto. The cost of remediating such an attack is just too high, which is why so many SMBs fold within 6 months of experiencing a data breach.
DNS filtering is an important control to prevent malware and ransomware attacks over the Internet, both by blocking downloads of ransomware and malware and preventing employees from visiting phishing websites.
According to the Spiceworks survey, 38% of organizations have experienced at least one security incident as a result of employee Internet activity. By restricting access to certain categories of website and blocking known malicious websites, SMBs will be much better protected against costly attacks.
Add to that the amount of time that is lost to casual internet surfing and web filtering is a no-brainer. 28% of employees waste more than 4 hours a week on websites unrelated to their work, but the percentages rise to 45% at mid-sized businesses and 51% of employees in small businesses waste more than 4 hours a week on personal Internet use.
There is no latency with DNS filtering, plus controls can be implemented to restrict certain bandwidth heavy activities to improve network performance.
DNS Filtering for MSPs – The Ideal Web Filtering Solution
DNS web filtering is a low-cost cybersecurity solution that actually pays for itself in terms of the productivity gains and by preventing costly malware, ransomware, and phishing attacks. Further, in contrast to appliance-based web filters, DNS filtering requires no hardware purchases or software installations which means no site visits are required and the costs are affordable for most SMBs. DNS filtering can also be set up for clients remotely in a matter of minutes.
DNS filtering is ideal for MSPs as it is hardware and software independent. It doesn’t matter what devices and operating systems your clients have because DNS filtering simply forwards web traffic to a cloud-based filter without the need to install any clients or agents on servers or end points.
TitanHQ’s DNS filtering for MSPs has a low management overhead, so there is little in the way of ongoing maintenance required. A full suite of customizable reports can be automatically generated and sent to clients to show them what threats have been blocked, who in the organization has been trying to access restricted content, and which employees are the biggest drain on network performance. MSPs can easily add in web filtering to existing security packages to provide greater value or offer web filtering as an add-on service to generate extra, recurring monthly revenue and attract more business.

One of the ways that threat actors install malware is through malvertising – The placing of malicious adverts on legitimate websites that direct visitors to websites where malware is downloaded. The HookAds malvertising campaign is one such example and the threat actors behind the campaign have been particularly active of late.
The HookAds malvertising campaign has one purpose. To direct people to a website hosting the Fallout exploit kit. An exploit kit is malicious code that runs when a visitor lands on a web page. The visitor’s computer is probed to determine whether there are any vulnerabilities – unpatched software – that can be exploited to silently install files.
In the case of the Fallout exploit kit, users’ devices are checked for several known Windows vulnerabilities. If one is identified, it is exploited and a malicious payload is downloaded. Several malware variants are currently being delivered via Fallout, including information stealers, banking Trojans, and ransomware.
According to threat analyst nao_sec, two separate HookAds malvertising campaigns have been detected: One is being used to deliver the DanaBot banking Trojan and the other is delivering two malware payloads – The Nocturnal information stealer and GlobeImposter ransomware via the Fallout exploit kit.
Exploit kits can only be used to deliver malware to unpatched devices, so businesses will only be at risk of this web-based attack vector if they are not 100% up to date with their patching. Unfortunately, many businesses are slow to apply patches and exploits for new vulnerabilities are frequently uploaded to EKs such as Fallout. Consequently, a security solution is needed to block this attack vector.
HookAds Malvertising Campaign Highlights Importance of a Web Filter
The threat actors behind the HookAds malvertising campaign are taking advantage of the low prices offered for advertising blocks on websites by low quality ad networks – Those often used by owners of online gaming websites, adult sites, and other types of websites that should not be accessed by employees. While the site owners themselves are not actively engaging with the threat actors behind the campaign, the malicious adverts are still served on their websites along with legitimate ads. Fortunately, there is an easy solution that blocks EK activity: A web filter.
TitanHQ has developed WebTitan to allow businesses to carefully control employee Internet access. Once WebTitan has been installed – a quick and easy process that takes just a few minutes – the solution can be configured to quickly enforce acceptable Internet usage policies. Content can be blocked by category with a click of the mouse.
Access to websites containing adult and other NSFW content can be quickly and easily blocked. If an employee attempts to visit a category of website that is blocked by the filter, they will be redirected to a customizable block screen and will be informed why access has been prohibited.
WebTitan ensures that employees cannot access ‘risky’ websites where malware can be downloaded and blocks access to productivity draining websites, illegal web content, and other sites that have no work purpose.

Hackers are targeting healthcare organizations, educational institutions, hotels, and organizations in the financial sector, but restaurants are also in hackers’ cross-hairs. If restaurant cybersecurity solutions are not deployed and security vulnerabilities are not addressed, it will only be a matter of time before hackers take advantage.
Cyberattacks on restaurants can be extremely profitable for hackers. Busy restaurant chains process hundreds of credit card transactions a day. If a hacker can gain access to POS systems and install malware, customer’s credit card details can be silently stolen.
Cheddar’s Scratch Kitchen, Applebee’s, PDQ, Chili’s, B&BHG, Zaxby’s, Zippy’s, Chipotle, and Darden restaurants have all discovered hackers have bypassed restaurant cybersecurity protections and have gained access to the credit card numbers of large numbers of customers.
One of the biggest threats from a data breach is damage to a restaurant’s reputation. The cyberattack and data breach at Chipotle saw the brand devalued by around $400 million.
A restaurant data breach can result in considerable loss of customers and a major fall in revenue. According to a study by Gemalto, 70% of the 10,000 consumers surveyed said that they would stop doing business with a brand if the company suffered a data breach. Most restaurants would not be able to recover from such a loss.
Restaurant Cybersecurity Threats
Listed below are some of the common restaurant cybersecurity threats – Ways that hackers gain access to sensitive information such as customers’ credit card numbers.
The primary goal of most restaurant cyberattacks is to gain access to customers’ credit card information. One of the most common ways that is achieved is through malware. Malicious software is installed on POS devices to silently record credit card details when customers pay. The card numbers are then sent to the attacker’s server over the Internet.
Phishing is a type of social engineering attack in which employees are fooled into disclosing their login credentials and other sensitive information. Phishing emails are sent to employees which direct them to a website where credentials are harvested. Phishing emails are also used to install malware through downloaders hidden in file attachments.
Whenever an employee or a customer accesses the Internet they will be exposed to a wide range of web-based threats. Websites can harbor malware which is silently downloaded onto devices.
Restaurants often have Wi-Fi access points that are used by employees and guests. If these access points are not secured, it gives hackers an opportunity to conduct attacks and gain access to the restaurant network, install malware, intercept web traffic, and steal sensitive information.
Restaurant Cybersecurity Tips
Listed below are some of the steps you should take to protect your customers and make it harder for hackers to gain access to your systems and data.
Conduct a risk analysis to identify all vulnerabilities that could potentially be exploited to gain access to networks and customer data
Develop a risk management plan to address all vulnerabilities identified during the risk assessment
Ensure all software and operating systems are kept up to date and are promptly patched
Become PCI compliant – All tools used to accept payments must comply with PCI standards
Implement security controls on your website to ensure customers can use it securely. Sensitive data such as loyalty program information must be protected.
Ensure you implement multi-factor authentication on all accounts to protect systems in case credentials are compromised
Ensure all default passwords are changed and strong, unique passwords are set
Ensure all sensitive data are encrypted at rest and in transit
Secure Wi-Fi networks with a web filter to block malware downloads and web-based threats
Implement a spam filter to block phishing attempts and malware
Provide cybersecurity training to staff to ensure they can recognize the common restaurant cybersecurity threats

Business and leisure travelers looking for secure hotel Wi-Fi access in addition to fast and reliable Internet access. If you take steps to secure hotel WiFi access points, you can gain a significant competitive advantage.
The Importance of Hotel Wi-Fi to Guests
The number one hotel amenity that most travelers can simply not do without is fast, free, reliable, Internet access. In 2013, a joint study conducted by Forrester Research and Hotels.com revealed that 9 out of ten gusts rated Wi-Fi as the top hotel amenity. 34% of respondents to the survey said free Wi-Fi was a ‘deal breaker.’ Now four years on, those percentages will certainly have increased.
Wi-Fi access is essential for business travelers as they need to be able to stay in touch with the office and be able to communicate with their customers. Leisure travelers need free Internet access to keep in touch with friends, look up local attractions, and enjoy cheap entertainment in the comfort of their rooms. Younger travelers need constant access to social media accounts and online games such as Fortnite as they get at home.
It doesn’t matter whether you run a small family bed and breakfast or a large chain of hotels, Wi-Fi access for guests is essential. Any hotel that doesn’t have reliable and fast Wi-Fi will lose business to establishments that do.
It is now easy for potential guests to check if an establishment has Wi-Fi and even find out about the speed and reliability of the connection. The hotelwifitest.com website lets travelers check the speed of Internet access in hotels before booking.
Guests don’t post rave reviews based on the speed of Internet connections, but they will certainly make it known if Internet access is poor or nonexistent. Many of the negative comments on hotel booking websites and TripAdvisor are related to Wi-Fi. Put simply, you will not get anywhere near the same level of occupancy if your Wi-Fi network isn’t up to scratch.
Secure Hotel Wi-Fi is Now as Important as Offering Wi-Fi to Guests
Businesses are now directing a considerable percentage of their IT budgets to cybersecurity to prevent hackers from gaining access to their networks and sensitive data. Securing internal systems is relatively straightforward, but when employees have to travel for work and access networks remotely, hackers can take advantage.
When employees must travel for business, their hotel is often the only place where they can connect to the office network and their email. They need to know that they can login securely from the hotel and that doing so will not result in the theft of their credentials or a malware infection. A hotel will be failing its business customers if it does not offer safe and secure Wi-Fi access.
All it takes is for one malware infection or cyberattack to occur while connected to a hotel Wi-Fi network for the reputation of the hotel to be tarnished. Hotels really cannot afford to take any risks.
Multiple Levels of Wi-Fi Access Should be Offered
Parents staying in hotels will want to make sure that their children can access the Internet safely and securely and will not accidentally or deliberately be able to gain access to age-inappropriate websites. If a hotel claims to be family-friendly, that must also extend to the Wi-Fi network. Any hotel that fails to prevent minors from accessing obscene images while connected to hotel Wi-Fi cannot claim it is family-friendly.
Hotels can offer Wi-Fi access for families that blocks adult websites and anonymizers, which are commonly used to bypass filtering controls. Safe Search can also be enforced, but not all users will want that level of control.
To cater to the needs of all guests, different levels of Wi-Fi access are likely to be required. Some guests will want to be able to access the types of websites they do at home without restrictions and business travelers will certainly not want anonymizers to be blocked. Some customers insist on the use of VPNs when employees connect to their business network or email.
Hotels that implement a web filtering solution can easily create different tiers of Internet access. One for families and a less restrictive level for other users. Free internet access could be limited to a basic level that includes general web and email access but blocks access to video streaming services such as YouTube and Netflix. Those services could be offered as part of a low-cost Wi-Fi package to generate some extra revenue. These tiers can easily be created with a web filtering solution.
How to Easily Secure Hotel Wi-Fi
Offering secure hotel Wi-Fi to guests does not require expensive hardware to be purchased. While appliance-based web filters are used by many businesses, there is a much lower cost option that is better suited for hotel use.
A cloud-based web filter for Wi-Fi – such as WebTitan for Wi-Fi -is the easiest to implement secure hotel Wi-Fi solution. With WebTitan Cloud for Wi-Fi, your Wi-Fi network can be secured with just a simple change to your DNS records. No hardware is required and there is no need to install any software. One solution will protect all Wi-Fi access points and can be up and running in a matter of minutes. There is no limit on the number of access points that can be protected by WebTitan Cloud for Wi-Fi.
Once your DNS is pointed to WebTitan, you can apply your content controls – which is as simple as clicking on a few checkboxes to block categories of web content that your guests shouldn’t be allowed to access.
You can create multiple accounts with different controls – one for business users, one for families, and one for employees for example. No training is required to administer the solution as it has been developed to require no technical skill whatsoever. All of the complex elements of web filtering are handled by TitanHQ.
If you run a hotel and you are not currently filtering the internet, talk to TitanHQ about how you can your secure your hotel Wi-Fi access points, protect your guests, and ensure all users can access the Internet safely and securely.
Find out why WiFi filters for coffee shops are so important and how the failure to filter the Internet could prove to be extremely harmful to your brand.
Serving the best coffee in town will certainly bring in the crowds, but there is more to a successful coffee shop than providing patrons with a morning jolt of caffeine and comfy chairs. Coffee is big business and there is stiff competition when it comes to providing jitter juice to the masses.
In addition to free newspapers, high quality flapjacks and a fine blend of beans, patrons look for the other necessity of modern life: Free Internet access. Establishments that offer free, reliable WiFi access with decent bandwidth stand a much better chance of attracting and retaining customers.
However, simply setting up a WiFi router is no longer enough. Coffee shops also need to make sure that the WiFi network that their customers connect to is safe and secure. Just as the provision of free WiFi can translate into positive TripAdvisor and Yelp reviews, coffee shops that fail to secure their connections and exercise control over the content that can be accessed can easily get the reverse. WiFi filters for coffee shops ensure that customers’ activities online can be carefully controlled.
Why Unfiltered WiFi Networks Can Result in Bad Reviews
It is important for all shops to ensure that their WiFi networks cannot be used for any illegal or unsavory activities. If a webpage is not suitable for work, it is not suitable for a coffee shop. While there all manner of sites that should be blocked with WiFi filters for coffee shops, one of the most important categories of content is Internet porn.
While enjoying a nice coffee, patrons should not be subjected to obscene videos, images or audio. All it takes is for one patron to catch a glimpse of porn on another customer’s screen to trigger a bad review. The situation would be even worse if a minor caught a glimpse or even deliberately accessed adult content while connected to the WiFi network. A bad TripAdvisor review could easily send potential customers straight to the competition and a social media post could all too easily go viral.
What are the chances of that happening? Well, it’s not just a hypothetical scenario, as Starbucks discovered. In 2011, Starbucks received a warning that minors had been subjected to obscene content in its coffee shops and the chain did little about the complaints. The following year, as the bad feedback continued, the story was picked up by the media.
The bad feedback mounted and there were many calls for the public to boycott Starbucks. In the UK, Baroness Massey announced to the House of Lords that she had boycotted the brand and heavily criticized the chain for failing to set an example. Naturally, competitors – Costa Coffee for example – were more than happy to point out that they had been proactive and already provided filtered Internet to prevent minors from accessing adult content on their WiFi networks.
It was not until 2016 when Starbucks took action and implemented WiFi filters for coffee shops in the UK and started providing family-friendly WiFi access. A chain the size of Starbucks could weather the bad press. Smaller coffee shops would no doubt fare far worse.
WiFi Filters for Coffee Shops are Not Only About Blocking Adult Content
WiFi filters for coffee shops are important for blocking obscene content, but that is far from the only threat to a brand. The Internet is home to all manner of malicious websites that are used to phish for sensitive information and spread malicious software such as malware and ransomware. WiFi filters for coffee shops can be used to carefully control the content that can be accessed by consumers, but they can also keep them protected from these malicious sites.
Just as users have safe search functionality on their home networks, they expect the same controls on public WiFi access points. Phishing attacks and malware infections while connected to coffee shop WiFi networks can also be damaging to a brand. With WiFi filters for coffee shops, instead of being phished, a user will be presented with a block screen that explains that the business has blocked access to a malicious site to keep them protected and that will send a positive message that you care about your customers.
Once WiFi filters for coffee shops have been implemented, it is possible to apply to be assessed under the government’s Friendly Wi-Fi scheme. That will allow a coffee shop to display the friendly WiFi symbol and alert potential customers that safe, secure, family-friendly filtered Internet access is provided.
WebTitan – TitanHQ’s Easy to Implement WiFi Filters for Coffee Shops
Fortunately, WiFi filters for coffee shops are not expensive or difficult to implement. If you use a cloud-based solution such as WebTitan Cloud for WiFi, you will not need to purchase any hardware or install any software. Your WiFi network can be secured in a matter of minutes. A simple change to point your DNS to WebTitan is all that is required (you can be talked through that process to get you up and running even faster).
Since the controls are highly granular, you can easily block any type of web content you wish with a click of a mouse, selecting the categories of content you don’t want your users to access through the web-based control panel. Malicious sites will automatically be blocked via constantly updated blacklists of known malicious and illegal web pages.
With WebTitan you are assured that customers cannot view adult and illegal content, you can block illegal file sharing, control streaming services to save bandwidth, and enforce safe search on Google and apply YouTube controls.

Vulnerabilities in the VPNs NordVPN and ProtonVPN have been identified that allow execution of arbitrary code with system level privileges, highlighting the risk that can be introduced if VPN software is not kept fully patched and up to date.
VPNs May Not be As Secure as You Think
One common method used to securely access the Internet on public WiFi networks is to connect through a VPN. A VPN helps to prevent man-in-the-middle attacks and the interception of data by creating a secure tunnel through which data flows. Using VPN software means a user’s data is encrypted preventing information from being accessed by malicious actors.
While the connection is secured using a VPN, that does not always mean that a user is well protected. VPNs may not be quite as secure as users believe. Like any software, there can be vulnerabilities in VPNs that can be exploited. If the latest version of VPN software is not used, data may be vulnerable.
High Severity Vulnerabilities Identified in Popular VPNs
Recently, two of the most popular VPN clients have been found to contain a privilege escalation bug that could be exploited to allow an attacker to execute arbitrary code with elevated privileges.
The bug is present in NordVPN and ProtonVPN clients, both of which use the open-source OpenVPN software to create a tunnel through which information passes. In April, a flaw was identified which allowed an attacker with low level privileges to run arbitrary code and elevate their privileges to system level. Further, the flaw was not difficult to exploit.
A change could easily be made to the OpenVPN configuration file, adding parameters such as “plugin”, “script-security”, “up”, and “down”. Files specified within those parameters would be executed with elevated privileges. The flaw was identified by security researcher Fabius Watson of VerSprite Security, and prompt action was taken to patch the flaw.
However, while patches were issued by NordVPN and ProtonVPN that prevented the “plugin”, “script-security”, “up”, and “down” parameters from being added to the configuration file by standard users, the flaw had only been partially corrected.
Researchers at Cisco Talos discovered the same parameters could still be added to the configuration file if they were added in quotation marks. Doing that would bypass the mitigations of the patches. These vulnerabilities have been tracked under separate CVE codes – CVE-2018-3952 for ProtonVPN and CVE-2018-4010 for NordVPN. Both flaws are considered high-severity and have been assigned a CVSS v3 base score of 8.8 out of 10.
NordVPN and ProtonVPN have now released an updated patch which prevents the addition of these parameters using quotation marks, thus preventing threat actors from exploiting the vulnerability. Both vendors have tackled the problem in different ways, with ProtonVPN opting to put the configuration file in the installation directory to prevent standard users from making any changes, while NordVPN used an XML model to generate the configuration file. Standard users are not able to modify the template.
Securing Connections on Public WiFi Access Points
VPNs are an excellent way of improving security when connecting to public WiFi networks, but policies and procedures should be implemented to ensure that patches are applied promptly. It is not always possible to configure VPN clients to automatically update to the latest version. If vulnerabilities in VPNs are not addressed, they can be a major security weak point.
An additional protection that can be implemented to protect remote workers when connecting to WiFi networks is a web filtering solution such a WebTitan. WebTitan allows businesses to carefully control the web content that can be accessed by employees no matter where they connect – through wired networks, business WiFi networks, and when connecting to the Internet through public WiFi networks.
By controlling the types of sites that can be accessed, and using blacklists of known malicious sites, the potential for malware downloads can be greatly reduced.
If you want to improve WiFi security or implement web filtering controls for remote workers, contact the TitanHQ team today to find out more about WebTitan and the difference it can make to your security posture.
A new exploit kit has been detected that is being used to deliver Trojans and GandCrab ransomware. The Fallout exploit kit was unknown until August 2018, when it was identified by security researcher Nao_sec. Nao_sec observed the Fallout exploit kit being used to deliver SmokeLoader – a malware variant whose purpose is to download other types of malware.
Nao_sec determined that once SmokeLoader was installed, it downloaded two further malware variants – a previously unknown malware variant and CoalaBot – A HTTP DDoS Bot that is based on August Stealer code. Since the discovery of the Fallout exploit kit in August, it has since been observed downloading GandCrab ransomware on vulnerable Windows devices by researchers at FireEye.
While Windows users are being targeted by the threat group behind Fallout, MacOS users are not ignored. If a MacOS user encounters Fallout, they are redirected to webpages that attempt to fool visitors into downloading a fake Adobe Flash Player update or fake antivirus software. In the case of the former, the user is advised that their version of Adobe Flash Player is out of date and needs updating. In the case of the latter, the user is advised that their Mac may contain viruses, and they are urged to install a fake antivirus program that the website claims will remove all viruses from their device.
The Fallout exploit kit is installed on webpages that have been compromised by the attacker – sites with weak passwords that have been brute-forced and those that have out of date CMS installations or other vulnerabilities which have been exploited to gain access.
The two vulnerabilities exploited by the Fallout exploit kit are the Windows VBScript Engine vulnerability – CVE-2018-8174 – and the Adobe Flash Player vulnerability – CVE-2018-4878, both of which were identified and patched in 2018.
The Fallout exploit kit will attempt to exploit the VBScript vulnerability first, and should that fail, an attempt will be made to exploit the Flash vulnerability. Successful exploitation of either vulnerability will see GandCrab ransomware silently downloaded.
The first stage of the infection process, should either of the two exploits prove successful, is the downloading of a Trojan which checks to see if certain processes are running, namely: filemon.exe, netmon.exe, procmon.exe, regmon.exe, sandboxiedcomlaunch.exe, vboxservice.exe, vboxtray.exe, vmtoolsd.exe, vmwareservice.exe, vmwareuser.exe, and wireshark.exe. If any those processes are running, no further action will be taken.
If those processes are not running, a DLL will be downloaded which will install GandCrab ransomware. Once files are encrypted, a ransom note is dropped on the desktop. A payment of $499 is demanded per device to unlock the encrypted files.
Exploit kits will only work if software is out of date. Patching practices tend to be better in the United States and Europe, so attackers tend to rely on other methods to install their malicious software in these regions. Exploit kit activity is primarily concentrated in the Asia Pacific region where software is more likely to be out of date.
The best protection against the Fallout exploit kit and other EKs is to ensure that operating systems, browsers, browser extensions, and plugins are kept fully patched and all computers are running the latest versions of software. Companies that use web filters, such as WebTitan, will be better protected as end users will be prevented from visiting, or being redirected to, webpages known to host exploit kits.
To ensure that files can be recovered without paying a ransom, it is essential that regular backups are made. A good strategy is to create at least three backup copies, stored on two different media, with one copy stored securely offsite on a device that is not connected to the network or accessible over the Internet.
Security awareness training best practices to help your organization tackle the weakest link in the security chain: Your employees.
The Importance of Security Awareness Training
It doesn’t matter how comprehensive your security defenses are and how much you invested on cybersecurity products, those defenses can all be bypassed with a single phishing email. If one such email is delivered to an end user who does not have a basic understanding of security and they respond to that message, malware can be installed, or the attacker can otherwise gain a foothold in your network.
It is the risk of such an attack that has spurred many organizations to develop a security awareness training program. By teaching all employees cybersecurity best practices – from the CEO to the lowest level workers – security posture can be greatly enhanced and susceptibility to phishing attacks and other cyberattacks will be greatly reduced.
However, simply providing employees with a training session when they join the company is not sufficient. Neither is it enough to give an induction in cybersecurity followed by an annual refresher training session. Employees cannot be expected to retain knowledge for 12 months unless frequent refresher training sessions are provided. Further, cybercriminals are constantly developing new tactics to fool end users. Training programs must keep up with those changing tactics.
To help organizations develop an effective security awareness training program we have compiled a list of security awareness training best practices to follow. Adopt these security awareness training best practices and you will be one step closer to developing a security culture in your organization.
Security Awareness Training Best Practices
Listed below are some security awareness training best practices that will help you develop an effective training program that will ultimately help you to prevent data breaches.
C-Suite Involvement is a Must
It is often said that the weakest link in the security chain are an organization’s employees. While that is undoubtedly true, the C-Suite is also a weak link. If the C-Suite does not take an active interest in cybersecurity and does not realize the importance of the human element in security, it is unlikely that sufficient support will be provided and unlikely that appropriate resources are made available. C-suite involvement can also help with organization-wide collaboration. It will be very difficult to create a security culture in an organization if there is no C-Suite involvement in cybersecurity.
An Organization-Wide Effort is Required
A single department will likely be given the responsibility for developing and implementing a security awareness program, but it will not be easy in isolation. Assistance will be required from other departments. The heads of different departments can help to ensure that the security awareness training program is given the priority it deserves.
To ease the burden on the IT department, members of other departments can be trained and can assist with the provision of support or may even be able to assist with the training efforts. Other departments, such as marketing, can help developing content for newsletters and other training material. The HR department can help by setting policies and procedures.
Creation of Security Awareness Training Content
There is no need to develop training content for employees from scratch as there are many free resources available that can give you a head start. Many firms offer high quality training material for a price, which is likely to be lower than the cost of developing training material in-house. Take advantage of these resources but make sure that you develop a training program that is specific to the threats faced by your organization and the sector in which you operate. Your training program must be comprehensive. If any gaps exist, they are likely to be exploited sooner or later.
Diversity of Training
A one-size-fits-all approach to training will ultimately fail. People respond differently to different training methods. Some may retain more knowledge through classroom-based training, others may need one-to-one training, and many will benefit more from CBT training sessions. Your training program should include a wide range of different methods to help with different learning styles. The more engaging your program is, the more likely knowledge will be retained. Use posters, newsletters, email security alerts, games, and quizzes and you will likely see major improvements in your employees’ security awareness.
You can develop a seriously impressive training program for your employees that looks perfect on paper, but if your employees only manage to retain 20% of the content, your training program will not be very effective. The only way you can determine how effective your training program is through attack simulations. Phishing simulation exercises and simulations of other attack scenarios should be conducted before, during, and after training. You will be able to assess how effective all elements of the training program have been, and it will give you the feedback you need to identify weak links and take action to improve your training program.
Security Awareness Training Needs to be a Constant Process
Security awareness training is not a checkbox item that can be completed and forgotten about for another year. Your program should be running constantly and should consist of an annual training session for all employees, semi-annual training sessions, and other training efforts spread throughout the year. The goal should be to make sure security issues are always fresh in the mind.
Cybersecurity best practices for restaurants that you can adopt to make your network more secure and prevent hackers from gaining access to your POS system and customers’ credit card information.
Cybercriminals are Targeting Restaurants’ POS Systems
If you run a busy restaurant you will most likely be processing thousands of credit and debit card transactions every month. Every time someone pays with a card you have a legal responsibility to ensure that the card details that are read through your point of sale (POS) system remain private and cannot be stolen by your employees or obtained by cybercriminals.
So far this year there have been several major cyberattacks on restaurants that have resulted in the credit and debit card numbers of customers being stolen. In August, Darden Restaurants discovered that hackers gained access to the POS system used in its Cheddar’s Scratch Kitchen restaurants and potentially stole over half a million payment card numbers.
Applebee’s, PDQ, Zippy’s, and Chili’s have all experienced cyberattacks in 2018 which have resulted in hackers gaining access to customers’ payment cards. Last year also saw several cyberattacks on restaurants, including attacks on Shoney’s, Arby’s, Chipotle, and the Sonic Drive-In chain. These restaurant cyberattacks are notable due to the amount of card numbers that were stolen. The cyberattack on Cheddar’s is thought to have resulted in the theft of more than half a million payment card numbers, expiry dates and CVV codes, while the Sonic data breach has been estimated to have impacted millions of customers.
Not all cyberattacks on restaurants are conducted on large restaurant chains. Smaller restaurants are also being attacked. These smaller establishments may not process anywhere near as many payment card transactions as a chain the size of Applebee’s, but the attacks can still prove profitable for criminals. Card details sell for upwards of $7, so the theft of 1,000 card numbers from a small restaurant will still generate a decent profit and the effort required to conduct cyberattacks on small restaurants is often far less than an attack on a large chain.
All restaurants are at risk of hacking. Steps must therefore be taken by all restaurants to make it as hard as possible for hackers to gain access to the network, POS systems, and customer data. With this in mind we have listed cybersecurity best practices for restaurants to adopt to avoid a data breach.
Cybersecurity Best Practices for Restaurants
Listed below are some cybersecurity best practices for restaurants to adopt to make it harder for hackers to gain access to your network and data. There is no silver bullet that will stop all cyberattacks, but these cybersecurity best practices for restaurants will help to improve your security posture.
Network Segmentation is a Must
You will most likely have multiple computers in use in your restaurant as well as many other devices that connect to your network via an ethernet connection or WiFi. Every device that connects to your network is a possible entry point that could be exploited by a hacker. It is therefore important to stake steps to ensure that if one device is compromised, access cannot be gained to your entire network. Your POS system needs to be segregated from other parts of the network and users should only be permitted to access parts of the network that are required to complete their assigned duties.
Patch Management and Vulnerability Scanning
All it takes is for one vulnerability to remain unaddressed for you to be vulnerable to attack. It is therefore essential to maintain an inventory of all devices that connect to your network and ensure that patches and software updates are applied on all those devices as soon as they are released. You should also conduct regular vulnerability scans to identify possible weak points and take prompt action to ensure those weak points are addressed.
Secure the Perimeter with a Firewall
One of the most important cybersecurity solutions to implement to prevent hackers from gaining access to your network is a firewall. A firewall monitors and controls incoming and outgoing network traffic and serves as a barrier between a trusted internal network and an untrusted external network. A firewall is also an important element of PCI compliance.
Implement a Spam Filter to Block Malicious Emails
Email is the most common vector used to install malware. Phishing attacks are commonplace and are an easy way for hackers to gain login credentials and get a foothold in the network. Use a spam filter such as SpamTitan to prevent malicious messages from being delivered to end users’ inboxes and block all malware-laced emails.
Protect Your WiFi Network with a Web Filtering Solution
Your WiFi network is a potential weak spot and must be secured. If you provide WiFi access to your customers, ensure they are only provided with access to a guest network and not the network used by your staff. Implement a web filter to control what users can do when connected to your network. A web filter will help to prevent malware from being downloaded and can be configured to block access to risky websites. WebTitan is an ideal web filter for restaurants to improve WiFi security.
Purchase Antivirus Software
Antivirus software is one of the most basic software solutions to protect against malware. Malware is commonly installed on POS systems to record and exfiltrate payment card information. Not only should you ensure that a powerful antivirus solution is installed, you should also ensure regular scans of the network are performed.
Provide Security Awareness Training to Staff
Your employees are a potential weak point in your security defenses. Don’t assume that your employees are security aware. Teach your staff cybersecurity best practices for restaurants, provide anti-phishing training, and explain about risky behaviors that could easily lead to a data breach.
Backup and Backup Again
You should perform regular backups of all your essential data to protect against saboteurs and provide protection against ransomware attacks. If disaster strikes, you will need to record all your data. Adopt the 3-2-1 approach to creating backups. Create three copies, on two separate media, and store one copy securely off site on an air-gapped device that is not connected to the Internet.
Vet your Vendors
Access to your network may be gained through your vendors. The cyberattack on PDQ restaurants occurred via a remote access tool used by one of its technology vendors. If a vendor is able to connect to your network, it is essential that they have appropriate security controls in place. Be sure to check how secure your vendor is and what controls they have in place to prevent hacking before giving them network access.
Adopt these cybersecurity best practices for restaurants and you will make it harder for hackers to gain access to your network and you should be able to avoid a costly data breach.
The importance of web filtering for businesses cannot be understated. Businesses can install a range of perimeter defenses, but if controls are not implemented to restrict the activities of employees, malware can easily be downloaded onto work devices. The cost of mitigating malware infections can be considerable. The NotPetya malware attacks last year cost Maersk around $300 million. The Ponemon Institute annual cost of a data breach study suggests the average cost of a data breach is now $3.6 million for large businesses.
There is no single software solution that can provide total protection for businesses. A range of security solutions are required to reduce risk to an acceptable level, and web filters are one such control that should now be used by all businesses.
A new campaign has been detected this week that demonstrates the importance of web filtering for businesses, highlighting one of the methods used to install malicious software on corporate devices. In this case, the aim of the campaign is to install adware, unwanted browser extensions, and PuPs, although this tactic is often used to install much more malicious software.
The individuals behind this campaign are using autogenerated content to create large quantities of websites that incorporate commonly used keywords related to popular celebrities and adult industry actors. The aim of the campaign is to get these webpages indexed by the search engines and appearing in the organic search engine listings. Individuals who search for these keywords are likely to be presented with these webpages.
Upon opening these webpages, a popup is launched that advises the user that their computer lacks the codecs and software necessary to play the video. To get the videos to play, they need to install a media player. If the end user chooses to install the media player, rather than the media player being installed, a bundle of other programs is downloaded and installed on their device. The campaign also directs users to webpages where they are encouraged to install browser extensions.
If an employee is actively searching for inappropriate website content, it is easy to see how that individual would proceed with a download, and in doing so, install any number of potentially malicious programs.
This is not a hypothetical situation – many employees do just that. A recent survey conducted by Spiceworks delved into the reasons why companies are increasingly using web filters. The primary reason was to prevent the installation of malware. Further, when asked about whether employees had caused problems by accessing inappropriate website content, 38% of respondents said they had experienced a data breach in the past 12 months as a result of employees visiting websites that were not necessary for work.
The survey also revealed the extent that employees are using the Internet for personal reasons. Out of the companies that had not implemented a web filter, it was estimated that 58% of employees were wasting more than 4 hours a week on personal internet use, while 26% of employees were wasting 7 or more hours on non-work-related websites. That adds up to 26 days a year lost by each of those employees.
A web filter can allow a company to improve the productivity of the workforce. Employees will always slack off from time to time, but web filters can help to reduce the number of lost hours. The survey showed that the percentages fell to 43% spending more than 4 hours a week on non-work-related sites and 18% spending more than 7 hours a week slacking off online when a web filter was deployed – a significant reduction in lost hours. Further, blocking social media websites saw the figure fall to 30% of employees wasting more than 4 hours a week on personal internet use.
Another important benefit of web filtering is to prevent the accessing of illegal website content. Companies can be legally liable for illegal activities by their employees, such as the downloading of copyright protected material through peer-to-peer file sharing networks. The survey revealed two thirds of companies were using their web filter to avoid legal liability and 84% were using a web filter to stop illegal activity online. Data leakage is also a serious concern. 57% of companies use web filters to prevent data leakage and hacking.
If you want to improve your security posture, reduce the potential for productivity losses, and reduce legal liability, a web filter and at least some form of content control is essential.
If you have yet to implement a web filter, are unhappy with your current provider, or would like further information on the importance of web filtering for businesses, call the TitanHQ team today for further information. A free trial is also available for WebTitan, the leading web filtering solution for businesses, to allow you to find out first hand the benefits that content control offers.
What is a Botnet? How are they used? What harm can be caused, and how can you prevent a computer from becoming part of a botnet? These and other questions answered.
What is a Botnet?
A botnet is simply a collection of computers and other Internet-connected devices that are controlled by a threat actor. Usually that control is achieved via a malware installation, with the malware communicating with the threat actor’s command and control server.
Once malware has been installed on one device, potentially it can propagate to other devices on the same network, creating a mini-army of slave devices under the threat actor’s control. Any computer with the malware installed is part of the botnet and can be used on its own or collectively with other compromised devices for malicious purposes.
What are Botnets Used For?
Botnets are often used to conduct Distributed Denial of Service (DDoS) attacks, with the devices in the botnet used to access a particular service simultaneously and flooding it with traffic making that service temporarily unavailable. The Mirai botnet, which mostly consists of vulnerable IoT devices, was used to take down large sections of the Internet, including some of the most popular websites such as Twitter and Netflix. DDoS attacks are now being conducted that exceed 1 terabits per second, largely due to sheer number of devices that are part of the botnet.
One of the biggest botnets ever assembled was made possible with Zeus malware, a banking Trojan that was particularly difficult to detect. In the United States, an estimated 3.6 million computers had been infected with the malware, making Zeus one of the biggest botnets ever created.
In addition to DDoS attacks, botnets are also used to send huge quantities of spam and phishing emails. The Necurs botnet is the world’s largest spamming botnet, delivering 60% of all spam emails. The Gamut spam botnet delivers around 37% of spam botnet traffic. These two spamming botnets are primarily used to send malicious messages containing email attachments with malicious macros that download malware such as the Dridex banking Trojan, and the ransomware variants Locky, Globelmposter, and Scarab.
Recently, the rise in the value of cryptocurrencies has made it highly profitable to use the processing power of botnets to mine cryptocurrency. When processing power is used for cryptocurrency mining, the performance of the computers will reduce significantly.
How Are Botnets Created?
Botnets can be created through several different methods. In the case of IoT devices, attackers often take advantage of weak passwords and default credentials that have not been changed. Since IoT devices are less likely to be updated automatically with the latest software and firmware, it is easier to exploit flaws to gain access to the devices. IoT Devices also rarely have antivirus controls, making infection easier and detection of malware much harder.
Computers are most commonly recruited into botnets through malware sent via spam email campaigns – such as those sent out by the spamming botnets. Malware is delivered via infected email attachments or links to malicious websites where malicious code is hosted. Messages can be sent via social media networks and chat apps, which also direct users to malicious websites where malware is downloaded.
Drive-by downloads are also common – Malware is downloaded by exploiting vulnerabilities in browsers, add-ons or browser plug-ins, often through exploit kits loaded on compromised websites.
Prevent a Computer from Becoming Part of a Botnet
It is much easier to prevent a computer from becoming part of a botnet than identifying a malware infection and eradicating it once it has been installed. To prevent a computer from becoming part of a botnet, it is necessary to use technological controls and adopt security best practices.
Businesses need to ensure all staff are trained to be more security aware and are told about the risks of opening email attachments or clicking links in emails from unknown senders. They should also be told not to automatically trust messages from contacts as their email accounts could have been compromised. Employees should be taught security best practices and risky behavior, such as connecting to public WiFi networks without using a VPN, should be eradicated.
All software must be kept up to date with patches applied promptly. This will reduce the risk of vulnerabilities being exploited to deliver malware. Antivirus software should be installed and configured to update automatically, and regular AV scans should be performed.
Firewalls should be used to implemented to prevent unauthorized network access and allow security teams to monitor internet traffic.
Spam filtering solutions should be implemented to block the majority of malicious messages from being delivered to end users’ inboxes. The more messages that are blocked, the less chance there is of an employee responding to a phishing email and inadvertently installing malware.
One way to prevent a computer from becoming part of a botnet that is often forgotten, is the use of a web filtering solution. A web filter, such as WebTitan, will prevent malware and ransomware downloads and block access to malicious websites sent via email or through web browsing.
Implement these controls and it will make it much harder for your organization’s computers to be infected with malware and added to a botnet.
A hacking group has succeeded in infecting hundreds of thousands of routers with VPNFilter malware. The scale of the malware campaign is astonishing. So far more than half a million routers are believed to have been infected with the malware, prompting the FBI to issue a warning to all consumers and businesses to power cycle their routers.
Power cycling the router may not totally eradicate the malware, although it will temporarily disrupt communications and will help to identify infected devices, according to a May 25 public service announcement issued by the FBI.
All users have been advised to change the password on their router, install firmware updates if they are available, and disable the router’s remote management feature.
According to the U.S. Department of Justice, the malware campaign is being conducted by the Sofacy Group, also known as Fancy Bear and APT28. The hacking group has ties to the Russian government with some believing the hacking group is directed by Russia’s military intelligence agency.
While most of the infected routers and NAS devices are located in Ukraine, devices in more than 50 countries are known to have been infected with the malware. VPNFilter malware is a modular malware with a range of different functions that include the ability to capture all information that passes through the router, block network traffic and prevent Internet access, and potentially, the malware can totally disable the router. The infected routers could also be used to bring down specific web servers in a DDoS attack.
Many common router models are vulnerable including Linksys routers (E1200, E2500, WRVS4400N), Netgear routers (DGN2200, R6400, R7000, R8000, WNR1000, WNR2000), Mikrotik RouterOS for Cloud Core Routers (V1016, 1036, 1072), TP-Link (R600VPN), QNAP (TS251, TS439 Pro and QNAP NAS devices running QTS software).
The motive behind the malware infections is not known and neither the method being used to install the malware. The exploitation of vulnerabilities on older devices, brute force attacks, and even supply chain attacks have not been ruled out.
The FBI has taken steps to disrupt the malware campaign, having obtained a court order to seize control of a domain that was being used to communicate with the malware. While communications have now been disrupted, if a router has been compromised the malware will remain until it is removed by the router owners.
How to Update Your Router
While each router will be slightly different, they can be accessed by typing in 192.168.1.1 into the browser and entering the account name and password. For many users this will be the default login credentials unless they have been changed during set up.
In the advanced settings on the router it will be possible to change the password and disable remote management, if it is not already disabled. There should also be an option to check the firmware version of the router. If an update is available it should be applied.
You should then either manually power cycle the router – turn it off and unplug it for 20 seconds – or ideally use the reboot settings via the administration panel.
DrayTek Discovers Actively Exploited Zero Day Vulnerability
The Taiwanese broadband equipment manufacturer DrayTek has discovered some of its devices are at risk due to a zero-day vulnerability that is being actively exploited in the wild. More than 800,000 households and businesses are believed to be vulnerable although it is unknown how many of those devices have been attacked to date.
The affected devices are Vigor models 2120; 2133; 2760D; 2762; 2832; 2860; 2862; 2862B; 2912; 2925; 2926; 2952; 3200; 3220 and BX2000, 2830nv2; 2830; 2850; and 2920.
The vulnerability allows the routers to be compromised via a Cross-Site Request Forgery attack, one where a user is forced to execute actions on a web application in which they are currently authenticated. While data theft is possible with this type of attack, the attackers are using this attack to change configuration settings – namely DNS settings. By making that change, the attackers can perform man in the middle attacks, and redirect users from legitimate sites to fake sites where credentials can be stolen.
A firmware update has now been released to correct the vulnerability and all users of vulnerable DrayTek devices are being encouraged to check their DNS settings to make sure they have not been altered, ensure no additional users have been added to the device configuration, and apply the update as soon as possible.
When accessing the router, ensure no other browser windows are open. The only tab that should be open is the one used to access the router. Login, update the firmware and then logout of the router. Do not just close the window. Also ensure that you set a strong password and disable remote access if it is not already disabled.
Many small businesses purchase a router and forget about it unless something goes wrong and Internet access stops. Firmware updates are never installed, and little thought is given to upgrading to a new model. However, older models of router can be vulnerable to attack. These attacks highlight the need to keep abreast of firmware updates issued by your router manufacturer and apply them promptly.
In this post we explore some of the common wireless network attacks and offer advice on simple steps that can be taken to secure wireless networks and prevent costly data breaches.
Many Businesses are Neglecting WiFi Security
Many businesses have moved from wired to wireless technologies which has had a negative impact on their security posture. Wired networks are generally a lot easier to secure that wireless networks, and poor implementation often introduces vulnerabilities. Many businesses also fail to perform a thorough risk analysis which means those vulnerabilities are not identified and addressed. Because of these security flaws, and the ease of exploiting them, wireless networks attacks are common.
The Importance of WiFi Security
Wi-Fi access used to be something you had to pay for, but now free WiFi is something many people take for granted. Visitors to a hotel, coffee shop, bar, retail outlet, or restaurant now expect WiFi to be provided free of charge. The decision to use a particular establishment is often influenced by whether free WiFi is available, but increasingly the quality of the connection is a factor in the decision process.
The quality of the WiFi on offer is not just a question of there being enough bandwidth and fast internet speeds. Parents often choose to visit establishments that provide secure WiFi with content control, for instance, businesses that have been verified under the Friendly WiFi scheme. In order to be accredited under the scheme, businesses must have implemented appropriate filtering controls to ensure minors are prevented from accessing age-inappropriate material.
The massive rise in cyberattacks via public WiFi networks and warnings about WiFi risks in the mainstream media have seen many consumers choose to frequent establishments that offer secure WiFi access.
If you run a business and are providing WiFi to customers or if you are considering adding a WiFi hotspot to attract more customers, be sure to consider the security of the network. The past couple of years have seen many attacks on WiFi networks and customers who use those wireless services. The increase in WLAN attacks means WiFi security has never been so important.
Before covering some of the most common wireless attacks, it is worthwhile exploring some of the common wireless vulnerabilities that can be exploited to eavesdrop on traffic, infect users with malware, and steal sensitive information.
Common Wireless Vulnerabilities
Listed below are some of the most common wireless network vulnerabilities and steps that can be taken to prevent the vulnerabilities from being exploited. These wireless network vulnerabilities could easily be exploited in real world attacks on wireless networks to steal sensitive data, take control of a router or connected device, or install malware or ransomware.
Use of Default SSIDs and Passwords
WIFi access points are shipped with a default SSID and password which need to be changed, but all too often, those default passwords are left in place. That makes it easy for an attacker to login and take control of the router, change settings or firmware, load malicious scripts, or even change the DNS server so that all traffic is directed to an IP owned by the attacker. Default passwords must be changed to prevent anyone within range of the signal from connecting and sniffing traffic.
If wireless controllers are used to manage WiFi access points via web interfaces, make sure the default passwords are also changed. These default passwords can be easily found online and can be used to attack wireless networks.
Placing an Access Point Where Tampering Can Occur
If the access point is placed in a location where it can be physically accessed, tampering can occur. It takes just seconds to revert the access point to factory default settings. Make sure the access point is located in a secure location, such as a locked closet.
Use of Vulnerable WEP Protocol
The Wired Equivalent Privacy (WEP) protocol was the first protocol used to encrypt wireless traffic. WEP, as the name suggests, was intended to make wireless networks as secure as their wired counterparts, but that does not make WEP wireless networks secure.
WEP is based on the RC4 cypher, which is secure. The problem is how RC4 is implemented in WEP. WEP allows an initialization vector to be re-used, and the re-use of keys is never a good idea. That allows an attacker to crack the encryption with ease. Several other vulnerabilities have been identified in WEP which make it far from secure.
Even though WEP has been depreciated and there are much more secure wireless encryption protocols to use, many businesses continue to use WEP in the mistaken belief that it is secure. WEP is more secure than no encryption at all – bad security is better than no security – but there are much more secure options for encrypting WiFi traffic. If you want to improve security and prevent WLAN attacks, upgrade to WPA2 or WPA3, which use the much more secure Advanced Encryption Standard (AES) and lack the vulnerabilities of WEP.
WPA2 Krack Vulnerability
WPA may be more secure than WEP, but it is not without its own wireless vulnerabilities. Two Belgian researchers – Mathy Vanhoef and Frank Piessens of the University of Leuven – identified a serious flaw in the WPA security protocol. The flaw was named KRACK, short for Key Reinstallation Attack. The flaw can be exploited in a man-in-the-middle attack to steal sensitive data sent via the WPA encrypted WiFi connection. If the WPA flaw is exploited, an attacker could eavesdrop on traffic and obtain banking credentials, passwords, and credit card information.
The vulnerability exists in the four-way handshake. An encrypted WPA2 connection starts with a four-way handshake, but not all parts of that handshake are required. To speed up re-connections, the third part is retransmitted. That third part of the handshake may be repeated several times, and it is this step that could be used in a wireless network attack.
By repeatedly resetting the nonce transmitted in the third step of the handshake, an attacker can gradually match encrypted packets and discover the full keychain used to encrypt traffic.
A threat actor could set up a clone of a WiFi access point that a user has previously connected to – an evil twin. To the user, nothing would appear untoward as Internet access would be provided via that evil twin. An attacker can force a user to connect to the cloned WiFi network and all information sent via that evil twin WiFi network can be intercepted. While the attack will not work on sites with SSL/TLS encryption, tools can be used that make this possible by forcing a user to visit an HTTP version of the website.
In order to execute a KRACK WiFi attack, the WiFi network must be using WPA2-PSK or WPA-Enterprise and the attacker needs to be within range of the WiFi signal. Virtually all routers currently in use are vulnerable to KRACK WiFi attacks. The best defense is to keep routers up to date and for users to only connect to wireless networks using a paid-for, up to date VPN. The issue has been addressed in WPA3, which is supported by the latest wireless access points. However, even with this exceptionally common wireless network vulnerability, WPA2 is still far more secure than WEP.

What are the Most Common Wireless Network Attacks?
Many of the most common wireless network attacks are opportunistic in nature. WiFi hackers look for wireless networks that are easy to attack.
Hackers are more than happy to take advantage of poor security controls to gain access to sensitive information and distribute malware. Why waste time attacking well secured WiFi networks when there are plenty with scant or no security?
Poorly secured WiFi networks are also targeted by more sophisticated cybercriminals and organized crime groups to gain a foothold in the network. The attacks can be extremely lucrative. Access to a business network can allow ransomware to be installed and if malware can be installed on POS systems, the credit/debit card numbers of tens or hundreds of thousands of customers can be stolen.
Types of Wireless Network Attacks
There are several different types of WiFi attacks that hackers use to eavesdrop on wireless network connections to obtain passwords and banking credentials and spread malware. The main types of WiFi attacks are detailed below.
Fake WiFi Access Points, Evil Twins, and Man in the Middle Attacks
Visitors to hotels, coffee shops and malls often connect to the free WiFi on offer, but various studies have shown that care is not always taken when connecting. Customers often choose the WiFi access point based on the SSID without checking it is the wireless network set up by a particular establishment for customer use.
Criminals can easily set up fake WiFi access points, often using the name of the establishment in the SSID. A SSID called ‘Free Airport WiFi’ would be enough to get many people to connect. When customers connect to these rogue WiFi networks they can still access the Internet, so are unlikely to realize anything is wrong. However, once connected to that network, everything they do online will be monitored by cybercriminals. Sensitive information entered online, such as email addresses and passwords, credit card numbers, or banking credentials, can and will be stolen.
How is this done? The attacker simply creates a hotspot on a smartphone and pairs it with a tablet or laptop. The hacker can then sit in a coffee shop drinking a latte while monitoring the traffic of everyone that connects. Alternatively, they can use a router with the same name and password as the one currently in use. This may also have a stronger WiFi signal, which may see more people connect. Through the “evil twin” all traffic will be plainly visible to the attacker and all data sent over the network can be captured.
Fake access points and evil twins are among the most common wireless network attacks. They are easy to conduct, require little technical skill, and are very effective. One study indicated more than a third of WiFi hotspot users take no precautions when accessing WiFi hotspots and frequently connect to unsecured networks.
Packet Sniffing: Interception of Unencrypted Traffic
Research by Kaspersky Lab in 2016 showed more than a quarter of public Wi-Fi hotspots set up in malls were insecure and lacked even basic security controls. A quarter did not encrypt traffic at all, while research conducted by Skycure showed that five of the 10 busiest malls in the USA had risky WiFi networks.
One mall in Las Vegas was discovered to be operating 14 risky WiFi access points. Hackers can use packet sniffers to intercept traffic on unencrypted WiFi networks. Packet sniffing is one of the most common wireless attacks.
These common wireless network attacks are easy on older routers, such as those using WEP encryption. WPA offers better security, WPA2 is better still, or ideally, the new WPA3 encryption protocol should be used if it is supported by your access point.
War driving is a technique used to identify and map vulnerable access points. The name comes from the fact that attackers drive around a neighborhood and use a laptop with a GPS device, antenna to identify and record the location of wireless networks. This technique is effective, since many WiFi networks used by businesses extend beyond the confines of the building and poor security controls are applied to secure those networks.
Warshipping is a more efficient method of attacking WiFi networks as it allows attacks to be conducted remotely, even if the attacker is not within range of a WiFi network. The tactic was explained by IBM X-Force Red researchers at Black Hat USA. They used cheap (under $100) and easy to obtain components to create a single-board computer with WiFi and 3G capabilities that runs on a cell phone battery. The device can be used to locally connect to the WiFi network and sends information back to the attackers via the 3G cellular connection.
Since the device is small, it can easily be hidden inside a small package and getting that package into a building is easy. It can just be mailed. Since the package may be addressed to someone not working it the company, it could sit in the mailroom for a while before it is opened. Since the package can be tracked, the attackers will know when it is in the building. Alternatively, it could be hidden in any number of items from plant pots to teddy bears. If the device is within range of WiFi networks, it could be used to attack those networks.
Hashed network access codes can be sent back to the attackers to crack, and the device can then connect to WiFi networks in the building and harvest data. The device could be used in a man-in-the-middle attack by impersonating an internal WiFi network.
Many businesses use MAC filtering to prevent specific devices from connecting to their WiFi networks. While this is useful for preventing individuals from taking advantage of free WiFi for customers, this method of blocking users can be easily bypassed. It is easy to spoof a MAC address and bypass this filtering control.
Examples of WiFi Network Attacks
Attacks on wireless networks are not just theoretical. Listed below are some examples of common wireless networks attacks that have resulted in the installation of malware or theft of sensitive information. These latest wireless security attacks could easily have been prevented had appropriate security controls been implemented.
Latest Wireless Security Attacks
Tel Aviv Free WiFi Network Hacked
One notable example of how easy it can be for a hacker to take over a WiFi network comes from Tel Aviv. Tel Aviv offers a city-wide free WiFi network, which incorporates basic security controls to keep users secure on the network. However, it did not prove to be as secure as city officials thought.
While commuting home, Tel Aviv resident Amihai Neiderman noticed a new WiFi access point had appeared. The FREE_TLV access point was provided by the city and Neiderman decided to test its security controls. After determining the IP address through which WiFi clients accessed the Internet, he disconnected, scanned the router, and discovered the web-based login interface was run through HTTPS port 443.
While he found no major vulnerabilities, after extensive analysis he identified a buffer overflow vulnerability which he successfully exploited to take full control of the router. By doing so, if he was so inclined, he could have intercepted the traffic from tens of thousands of users.
Toasters Used to Hack Unsecured WiFi Networks
Perhaps not one of the most common WiFi network attacks, but notable none the less due to the rise in use of IoT devices. IoT capability has been incorporated into all manner of devices from toasters to washing machines. These devices can be vulnerable to supply chain attacks – Where hardware is altered to allow the devices to be used to attack WiFi networks. In 2016, Russian officials discovered chips imported from China had been altered and were being used to spread malware that could eavesdrop on unsecured WiFi networks from a range of 200 meters. They were used to infect those networks with malware that could steal information.
In Flight WiFi Network Hacked from the Ground
Cybersecurity expert Ruben Santamarta has demonstrated it is possible to hack into airline WiFi networks from the ground and view the internet activity of passengers and intercept their information. More worryingly, he was also able to gain access to the cockpit network and SATCOM equipment. He claims the same technique could be used for ships, industrial facilities and even military installations. He explained how he did it in his “Last Call for SATCOM security” presentation at the 2018 black hat hacker conference.
Orange Modems Leaking Wi-Fi Passwords
A vulnerability has been identified in Orange LiveBox ADSL modems that causes them to leak the SSID and WiFi passwords in plaintext. The flaw was identified by Bad Packets researchers who observed their honeypots being actively attacked. A search on Shodan showed there are nearly 20,000 vulnerable Orange modems than leak Wi-Fi passwords and SSIDs in plaintext. In many cases, the default credentials of admin/admin were still being used! The flaw means the WiFi networks could easily be attacked remotely. Attackers could change device settings, alter firmware, and even obtain the phone number and conduct a range of other attacks.
WeWork WiFi Security Flaws
WeWork, a provider of custom workspaces, private offices, and on-demand workspaces equipped with high-bandwidth WiFi, has made an error implementing those WiFi networks which makes them far from secure.
WeWork used the same WiFi password at many of its shared offices for several years. To make matters worse, that password was weak and regularly features in the top 25 lists of extremely poor passwords. However, there was no need to guess it as it was available in through the WeWork app in plaintext. Such a simple yet serious error placed all users of those workspaces at risk for several years. The researchers investigated several locations in San Francisco and found the same weak password used at multiple locations. Further, the WiFi network was only protected with WPA2 Personal security.
Teemu Airamo checked security of the workspace he had just moved into and found hundreds of other companies’ devices exposed. Subsequent scans on the WeWork network revealed an enormous amount of sensitive data had been exposed. Password reuse is never a good idea, and neither is using dictionary words or heaven forbid, any of the top 25 lists of shockingly awful passwords.
WiFi Networks Can be Used to Gain Access to Business Data
Creating a WiFi network for guests is simple. Ensuring it is secure and cannot be used for attacks on the business network or customers requires more thought and effort. Any business that allows customers to make purchases using credit and debit cards is a major target for hackers and poor WiFi security is likely to be exploited sooner or later. The past few years have seen many major attacks that have resulted in malware being installed on POS systems. These are now some of the most common wireless network attacks.
How Can Businesses Prevent the Most Common Wireless Network Attacks?
How can businesses protect against some of the most common wireless network attacks? While it is difficult to prevent the creation of fake WiFi hotspots, there are steps that can be taken to prevent many common wireless network attacks and keep the WiFi network secure.
Isolate the Guest Network
If your business network is not isolated from your guest WiFi network, it could be used to gain access to business data and could place your POS at risk of compromise. Use a router that offers multiple SSIDs – most modern routers have that functionality. These routers often have a guest SSID option or separate guest portal. Make sure it is activated when it is deployed. Alternatively, your wireless router may have a wireless isolation feature which will prevent WiFi users from accessing your internal network and other client devices. If you require multiple access points throughout your establishment, you are likely to need a VLAN or EoIP tunnel configuration – A more complicated setup that will require you to seek professional advice on security.
Encrypt WiFi Traffic with WPA2 or WPA3
If you have an old router that does not support WPA2 encryption it’s time for an upgrade. WPA2 is the minimum standard for WiFi security, and while it can still be cracked, it is time consuming and difficult. WPA3 has now been released and an upgrade should be considered. You should also make sure that WPS is turned off.
Update Firmware Promptly
All software and devices contain vulnerabilities and require updating. Software should be patched and devices such as routers will need to have their firmware upgraded when new versions are released. Check your device manufacturers website periodically for details of firmware updates and ensure your device is updated.
Create a Secure SSID
Your router will have a default SSID name, but this should be changed to personalize it to your business. If you make it easily identifiable, it will reduce the potential for rogue access points to be confused with your own. Ensure that you enforce WPA2 encryption with a shared key and post that information for your customers along with your SSID in a prominent place where they can see it.
Restrict WiFi Access
If your wireless router or access point is too powerful, it could be accessed from outside your premises. Choose a router that allows you to alter the strength of your signal and you can ensure only your customers will use your connection. Also ensure that your WiFi access point is only available during business hours. If your access points are left unsupervised when your business is closed, it increases the risk of an attack.
Secure Your Infrastructure
Administrator access can be abused, so ensure that your login name and your passwords are secure. If the default credentials are not changed, it will only be a matter of time before they are abused. Change the username from ‘admin’ or any other default username. Set a strong password that includes upper and lower-case letters, at least one number, and a special character. The password must be at least 8 characters although more is better. Alternatively use a 14-character+ passphrase.
Use a Web Filter
A web filtering solution is an essential protection for all WiFi networks. Web filters will prevent users from visiting websites and web pages that are known to have been compromised or have been confirmed as malicious. This will protect your customers from web-based threats such as drive by downloads, exploit kits and phishing. A web filter will also allow you to prevent your network from being used to download or view unacceptable content such as pornography and lets you control bandwidth usage to ensure all customers can enjoy decent Internet speeds.

A web-based malware distribution network that was redirecting around 2 million website visitors a day to compromised websites hosting exploit kits has been disrupted, crippling the malware distribution operation. The web-based malware distribution network – known as EITest – was using compromised websites to redirect web visitors to sites where exploits were used to download malware and ransomware, as well as redirect users to phishing websites and tech support scams that convinced visitors to pay for fake software to remove non-existent malware infections.
Due to the scale of the operation, removing the redirects from compromised websites is a gargantuan task. Efforts to clean up those sites are continuing, with national CERTs notified to provide assistance. However, the web-based malware distribution network has been sinkholed and traffic is now being redirected to a safe domain. Proofpoint researchers were able to seize a key domain that was generating C&C domains, blocking the redirects and re-routing them to four new EITest domains that point to an abuse.ch sinkhole.
The sinkhole has only been in operation for a month – being activated on March 15 – yet already it has helped to protect tens – if not hundreds of millions – of website visitors. In the first three weeks alone, an astonishing 44 million visitors had been redirected to the sinkhole from around 52,000 compromised websites and servers.
The majority of the compromised websites were running WordPress. Malicious code had been injected by taking advantage of flaws in the CMS and plugins installed on the sites. Vulnerabilities in Joomla, Drupal, and PrestaShop had also been exploited to install the malicious code.
The web-based malware distribution network has been in operation since at least 2011, although activity increased significantly in 2014. While previous efforts had been made to disrupt the malware distribution network, most failed and others were only temporarily successful.
The malicious code injected into the servers and websites primarily redirected website visitors to an exploit kit called Glazunov, and to a lesser extent, the Angler exploit kit. Those exploit kits probed for multiple vulnerabilities in software to download ransomware and malware.
The threat actors behind EITest are believed to have responded and have attempted to gain control of the sinkhole, but for the time being those efforts have been thwarted.
How to Improve Security and Block Web-Based Malware Attacks
While it is certainly good news that such a major operation has been disrupted, the scale of the operation highlights the extent of the threat of web-based attacks. Spam email may have become the main method for distributing malware and ransomware, but organizations should not ignore the threat from web-based attacks.
These attacks can occur when employees are simply browsing the web and visiting perfectly legitimate websites. Unfortunately, lax security by website owners can easily see their website compromised. The failure to update WordPress or other content management systems and plugins along with poor password practices makes attacks on the sites a quick and easy process.
One of the best cybersecurity solutions to implement to reduce the risk of web-based attacks is a web filter. Without a web filter in place, employees will be permitted to visit any website, including sites known to host malware or be used for malicious purposes.
With a web filter in place, redirects to malicious websites can be blocked, downloads of risky files prevented, and web-based phishing attacks thwarted.
TitanHQ is the leading provider of cloud-based web filtering solutions for SMBs and enterprises. WebTitan Cloud and WebTitan Cloud for WiFi allow SMBs and enterprises to carefully control the website content that can be accessed by their employees, guest network users, and WiFi users.

Phishing is commonly associated with spam emails, but it is not the only method of phishing as the PayPal text phishing scam below shows. Phishers use various methods to obtain sensitive information and phishing threats could arrive by email, text message, instant messenger services, and scams can be conducted over the phone.
Phishing is arguably the biggest cyber threat faced by businesses and consumers and can result in a malware infection, the encryption of files via ransomware, an email account being compromised, or the theft of sensitive data such as credit/debit card numbers or bank account information. A successful phishing attack could prove incredibly costly as bank accounts could easily be emptied. For businesses, malware infections can be catastrophic and billions are lost to business email compromise phishing scams each year.
There are approximately 200 million PayPal users, which makes the online payment service particularly attractive for phishers. PayPal is one of the world’s most commonly spoofed brands. If the brand is spoofed, there is a relatively high probability that the phishing email or text message will be received by a person who has a PayPal account. Further, PayPal accounts usually contain money and they are linked to a bank account and/or credit card. Gaining access to PayPal credentials can see the account and linked bank account emptied.
Phishers use a variety of social engineering techniques to fool end users into installing malware or disclosing their login credentials and other sensitive information. Spam email may be the main method of attack, although the use of text (SMS) messages – often referred to as SMiShing – is growing. This method of phishing can prove more successful for the attackers. The PayPal text phishing scam below is much harder to identify as malicious than many of the PayPal email phishing scams that have been detected in recent weeks.
Beware of this Credible PayPal Text Phishing Scam
This PayPal text phishing scam, and several variants along the same theme, have been detected in recent weeks. The text message appears to have been sent from PayPal from a short code number.
The message reads:
Your account is currently under review. Please complete the following security form to avoid suspension: http://bit[dot]ly/PayPal_-no-sms.eu
Another message reads:
Your account is under review. Please fill in the following security form to avoid lockout: http://bit[dot]ly/_payPal__
These PayPal text phishing scams works because many people do not carefully check messages before clicking links. Click the link on either of those two messages and you will be directed to a website that appears to be the official PayPal website, complete with branding and the normal web layout. However, the websites that the messages direct recipients to are scam sites.
Those sites naturally require the user to enter their login credentials. Doing so passes those credentials to the scammer. The scammer will then use those credentials to access the account, empty it of funds, and plunder the bank account(s) linked to the PayPal account. The password for the account may also be changed to give the attacker more time to make transfers and lock the genuine account holder out of the account.
These scams are particularly effective on smartphones as the full URL of the site being visited is not displayed in the address bar due to the small screen size. It may not be immediately apparent that an individual is not on the genuine PayPal website.
This PayPal text phishing scam shows that you need to be always be on your guard, whether accessing your emails or viewing text messages.
Don’t Become a Victim of an SMS Phishing Scam
The PayPal text phishing scam detailed above is just one example of how cybercriminals obtain sensitive information via text message. Any brand could be impersonated. Shortlinks are often used to hide the fact that the website is not genuine, as is altering the link text to mask the true URL.
To avoid becoming a victim of a SMiShing scam, assume any text message correspondence from a retailer or company could be a scam. If you receive a message – typically a warning about security – take the following steps.
Access your account by typing in the correct URL into your web browser. Do not use the link in the message.
Check the status of your account. If there is a freeze on your account, your account is under review, or it has been suspended, this will be clear when you try to log in.
If in doubt, contact the vendor by telephone or send an email, again using verified contact information and not any contact details supplied in the text message (or email).
Before logging in or disclosing any sensitive information online, check the entire URL to make sure the domain and web page are genuine.
PayPal Email Phishing Scams
This PayPal text phishing scam is one of thousands of phishing campaigns targeting PayPal users. While SMS phishing scams are increasing, most phishing attacks are conducted via email.
PayPal email phishing scams can be highly convincing. The emails contain the familiar PayPal logo, the text in the message body is often well written with no grammatical errors or spelling mistakes, the footers contain all the information you would expect, and the font is the same as that used in genuine PayPal messages.
The purpose of PayPal phishing emails will vary depending on the campaign, although typically the aim is:
To fool someone into disclosing their PayPal username/email address and password combination
To obtain a credit/debit card number, expiry date, and CVV code
To obtain bank account information and other personal information that allows the account to be accessed
To obtain a Social Security number and date of birth for use in identity theft and tax fraud
To install malware – Malware can capture all the above information and more
To install ransomware – Ransomware encrypts files and prevents them from being accessed unless a ransom payment is made
PayPal phishing emails can be very convincing and virtually indistinguishable from genuine communications; however, there are often signs that suggest all may not be what it seems.
Some of the common identifiers of PayPal phishing emails have been detailed below:
The messages contain questionable grammar or spelling mistakes.
The hyperlink text suggests one domain, when hovering the mouse arrow over the link shows it directs the user to a different domain.
The message does not address the account holder personally and starts with dear PayPal user, user, or PayPal member instead of using the first and last name or the business name.
A link in the email directs the recipient of the message to a website other than the genuine paypal.com domain or local site – paypal.ca, paypal.co.uk for example.
The website the user is asked to visit does not start with HTTPS and does not have the green padlock symbol in the address bar.
The email requests personal information be disclosed such as bank account details, credit card numbers, or security questions and answers.
A user is requested to download or install software on their device.
HTTPS Does Not Mean a Website is Genuine
There has been a general push to get businesses to make the switch from HTTP to HTTPS by installing an SSL certificate. The SSL certificate binds a cryptographic key to an organization’s details and activates both the padlock sign and changes a website to start with HTTPS. This ensures that the connection between the browser and the web server is encrypted and secured.
If the website has a valid SSL certificate installed, it reduces the potential for snooping on information as its entered in the browser – credit card information for example. However, what an SSL certificate will not offer is a guarantee that information is safe and secure.
A website owned by or controlled by a cybercriminal could have valid SSL certificate and start with HTTPS and have a green padlock. Disclosing information on that site could see sensitive information handed to a scammer.
As more and more businesses have made the transition to HTTPS, so have cybercriminals. According to the Anti-Phishing Working Group’s (APWG) Q1, 2018 phishing activity trends report, 33% of all phishing websites now use HTTPS and have valid SSL certificates. HTTPS and a green padlock do not mean that a website is genuine. It only means information entered on the site via the browser is secured.
Anti-Phishing Best Practices to Adopt
Exercise caution when someone sends you a hyperlink in a text message or email. The sender may not be who you think it is. A contact or family member’s email account may have been compromised or their phone stolen or the email address may have been spoofed.
Never open email attachments in unsolicited emails from unrecognized senders.
Beware of any email that suggests urgent action must be taken, especially when there is a threat or negative consequences for inaction – your account will be suspended or deleted for example.
If in doubt about the genuineness of an email, do not click any links or open any attachments. Simply delete the message.
Businesses should implement an advanced spam filter to prevent the majority of phishing emails from reaching inboxes.
Businesses should also implement DMARC to prevent spoofing of their brands.
Businesses should provide ongoing security awareness training to employees to teach them the skills required to identify phishing emails and smishing attempts such as this PayPal text phishing scam.

If you have yet to implement a web filtering solution to control the content that your employees can access at work, you are taking an unnecessary risk that could result in a costly malware infection, ransomware being installed on your network, or a lawsuit that could have been prevented by implementing basic web filtering controls. Many SMBs have considered implementing a web filter yet have not chosen a solution due to the cost, the belief that a web filter will cause more problems than it solves, or simply because they do not think it offers enough benefits. In this post we explain some of the common misconceptions about web filtering and attempt to debunk some common web filtering myths.
Common Web Filtering Myths
Antivirus Solutions Provide Adequate Protection from Web-Based Malware Attacks
Antivirus software is a must, although products that use signature-based detection methods are not as reliable as they once were. While antivirus companies are still quick to identity new malware variants, the speed at which new variants are being released makes it much harder to keep up. Further, not all malware is written to the hard drive. Fileless malware remains in the memory and cannot easily be detected by AV software. Antivirus software is still important, but you now need a host of other solutions to mount a reasonable defense against attacks. Layered defenses are now a must.
Along with AV software you should have anti spam software in place to block email-based threats such as phishing. You need to train your workforce to recognize web and email threats through security awareness training. Firewalls need to be set with sensible rules, software must be kept updated and patches must be applied promptly, regular data backups are a must to ensure recovery is possible in the event of a ransomware attack, and a web filtering solution should be installed.
A web filter allows you to carefully control the web content that can be accessed by employees. By using blacklists, websites known to host malware can be simply blocked, redirects via malvertising can be prevented, and controls can be implemented to prevent potentially malicious files from being downloaded. You can also prevent your employees from visiting categories of sites – or specific websites – that carry a higher than average risk.
There are other benefits to web filtering that can help you avoid unnecessary costs. By allowing employees to access any content, organizations leave themselves open to lawsuits. Businesses can be held liable for activities that take place on their networks such as accessing illegal content and downloading/sharing copyright-protected material.
Web Filtering is Prohibitively Expensive
Many businesses are put off implementing a web filtering solution due to the perceived cost of filtering the Internet. If you opt for an appliance-based web filter, you need to make sure you have an appliance with sufficient capacity and powerful appliances are not cheap. However, there is a low-cost alternative that does not require such a major cash commitment.
DNS filtering requires no hardware purchases so there is no major capital expenditure. You simply pay for the licenses you need and you are good to go. You may be surprised to find out just how low the price per user actually is.
Web Filtering is Too Complicated to Implement
Some forms of web filters are complex, and hardware-based filters will take some time to install and configure, which will take IT staff away from important duties. However, DNS based filters could not be any easier to implement. Implementing the solution is a quick process – one that will take just a couple of minutes. You just need to point your DNS to your web filtering service provider.
Even configuring the filter is straightforward. With WebTitan you are given a web-based portal that you can use to configure the settings and apply the desired controls. In its simplest form, you can simply use a checkbox option to select the categories of websites that you want to block.
Since WebTitan includes a database of malicious websites, any request to visit one of those websites will be denied. You can also easily upload third party blacklists, and for total control, use a whitelist to only allow access to specific websites.
Employees Will Just Bypass Web Filtering Controls
No web filtering solution is infallible, although it is possible to implement some basic controls that will prevent all but the most determined and skilled workers from accessing prohibited websites. Simple firewall rules can be easily set and you can block DNS requests to anything other than your approved DNS service. You can also set up WebTitan to block the use of anonymizers.
IT Support Will be Bombarded with Support Calls from Employees Trying to Access Blocked Websites
If you decide to opt for whitelisting acceptable websites, you are likely to be bombarded with support calls when users discover they are unable to access sites necessary for work. Similarly, if you choose to heavily filter the Internet and block most categories of website, then your helpdesk could well be swamped with calls.
However, for most companies, filtering the internet is simply a way of enforcing acceptable usage policies, which your employees should already be aware of. You are unlikely to get calls from employees who want access to porn at work, or calls from employees who want to continue gambling and gaming on the clock. Restrict productivity draining sites, illegal web content, phishing websites, and sites that are not suitable in the workplace, and explain to staff your polices in advance, and your support calls should be kept to a minimum.

Passwords should be complex and difficult to guess, but that makes them difficult to remember, so what about using password managers to get around that problem? Are password managers safe and secure? Are they better than attempting to remember passwords for every one of your accounts?
First of all, it is worth considering that most people have a great deal of passwords to remember – email accounts (work and personal), social media accounts, bank accounts, retail sites, and just about every other online service. If you rarely venture online and do not make online purchases, that means you will need to learn a handful of passwords (and change them regularly!).
Most people will have many passwords. Far too many to remember. That means people tend to choose easy to remember – and easy to guess – passwords and tend to reuse passwords on multiple sites.
These poor security practices are a recipe for disaster. In the case of password reuse, if one password is guessed, multiple accounts can be compromised. So, are password managers safe? If that is the alternative, then most definitely.
With a password manager you can generate a strong and impossible to remember password for every online account. That makes each of those accounts more secure. Emmanuel Schalit, CEO of Dashline, a popular password manager, said, “Sometimes, it’s better to put all your eggs in the same basket if that basket is more secure than the one you would be able to build on your own.”
That does mean that if the server used by the password manager company is hacked, you do stand to lose all of your passwords. Bear in mind that no server can ever be 100% secure. There have been hacks of password manager servers and vulnerabilities have been discovered (see below). Password managers are not risk-free. Fortunately, password managers encrypt passwords, so even if a server is compromised, it would be unlikely that all of your passwords would be revealed.
That said, you will need to set a master password to access your password manager. Since you are essentially replacing all of your unique passwords with a single password, if the master password is guessed, then your account can be accessed and with it, all of your passwords. To keep password managers safe and secure, it is important to use a strong and complex password for your account – preferably a passphrase of upwards of 12 characters and you should change that password every three months.
If you use a cloud-based password manager, it is possible that when that service goes down, you will not be able to access your own account. Fortunately, downtime is rare, and it would still be possible to reset your passwords. You could also consider keeping a local copy of your passwords and encrypting that file. In a worst-case scenario, such as the password manager company going bust, you would always have a copy. Some services will also allow you to sync your encrypted backups with the service to ensure local copies are kept up to date.
Flaws Discovered in Password Managers
Tavis Ormandy, a renowned researcher from the Google Project Zero team, recently discovered a flaw in Keeper Password Manager that could potentially be exploited to gain access to a user’s entire vault of stored passwords. The Keeper Password Manager flaw could not be exploited remotely without any user interaction. However, if the user was lured onto a specially crafted website while logged into their password manager, the attacker could inject malicious code to execute privileged code in the browser extension and gain access to the account. Fortunately, when Keeper was alerted to the flaw, it was rapidly addressed before the flaw could be exploited.
Last year Ormandy also discovered a flaw in LastPass, one of the most popular password managers. Similarly, that flaw could be exploited by luring the user to a specially crafted webpage via a phishing email. Similarly, that flaw was rapidly addressed. The LastPass server was also hacked the year before, with the attackers gaining access to some users’ information. LastPass reports that while it was hacked, users’ passwords were not revealed.
These flaws do go to show that while password managers are safe, vulnerabilities may exist, and even a password manager can potentially be hacked.
Are Password Managers Safe to Use?
So, are password managers safe? They can be, but as with any other software, vulnerabilities may exist that can leave your passwords exposed. It is therefore essential to ensure that password manager extensions/software are kept up to date, as is the case with all other software and operating systems.
Security is only as good as the weakest link, so while your password manager is safe, you will need to use a complex master password to prevent unauthorized individuals from accessing your password manager account. If that password is weak and easily guessable, it will be vulnerable to a brute force attack.
In addition to a complex master password, you should take some additional precautions. It would be wise not to use your password manager to save the password to your bank account. You should use two-factor authentication so if a new device attempts to connect to any of your online accounts, you will receive an alert on your trusted device or via email.
As an additional protection, businesses that allow the use of password managers should consider implementing a web filtering solution that prevents users from visiting known malicious websites where vulnerabilities could be exploited. By restricting access to certain categories of website, or whitelists of allowable sites, the risk of web-based attacks can be reduced to a low and acceptable level.
Password managers should also be used with other security solutions that provide visibility into who is accessing resources. Identity and access management solutions will help IT managers determine when accounts have been breached, and will raise flags when anomalous activity is detected.
The Terdot Trojan is a new incarnation of Zeus, a highly successful banking Trojan that first appeared in 2009. While Zeus has been retired, its source code has been available since 2011, allowing hackers to develop a swathe of new banking Trojans based on its sophisticated code.
The Terdot Trojan is not new, having first appeared in the middle of last year, although a new variant of the credential-stealing malware has been developed and is being actively used in widespread attacks, mostly in Canada, the United States, Australia, Germany, and the UK.
The new variant includes several new features. Not only will the Terdot Trojan steal banking credentials, it will also spy on social media activity, and includes the functionality to modify tweets, Facebook posts, and posts on other social media platforms to spread to the victim’s contacts. The Terdot Trojan can also modify emails, targeting Yahoo Mail and Gmail domains, and the Trojan can also inject code into websites to help itself spread.
Further, once installed on a device, Terdot can download other files. As new capabilities are developed, the modular Trojan can be automatically updated.
The latest variant of this nasty malware was identified by security researchers at Bitdefender. Bitdefender researchers note that in addition to modifying social media posts, the Trojan can create posts on most social media platforms, and suspect that the stolen social media credentials are likely sold on to other malicious actors, spelling further misery for victims.
Unfortunately, detecting the Terdot Trojan is difficult. The malware is downloaded using a complex chain of droppers, code injections and downloaders, to reduce the risk of detection. The malware is also downloaded in chunks and assembled on the infected device. Once installed, it can remain undetected and is not currently picked up by many AV solutions.
“Terdot goes above and beyond the capabilities of a Banker Trojan. Its focus on harvesting credentials for other services such as social networks and e-mail services could turn it into an extremely powerful cyber-espionage tool that is extremely difficult to spot and clean,” warns Bitdefender.
Protecting against threats such as banking Trojans requires powerful anti-malware tools to detect and block downloads, although businesses should consider additional protections to block the main attack vectors: Exploit kits and spam email.
Combosquatting is a popular technique used by hackers, spammers, and scammers to fool users into downloading malware or revealing their credentials.
Combosquatting should not be confused with typosquatting. The latter involves the purchasing of domains with transposed letters or common spelling mistakes to catch out careless typists – Fcaebook.com for example.
Combosquatting is so named because it involves the purchasing of a domain that combines a trademarked name with another word – yahoofiles.com, disneyworldamusement.info, facebook-security.com or google-privacy.com for example.
The technique is not new, but the extent that it is being used by hackers was not well understood. Now researchers at Georgia Tech, Stony Brook University and London’s South Bank University have conducted a study that has revealed the extent to which hackers, spammers, and scammers are using this technique.
The research, which was supported by the U.S. Department of Defense, National Science Foundation and the U.S. Department of Commerce, was presented at the 2017 ACM Conference on Computer and Communications Security (CCS) on October 31, 2017.
For the study, the researchers analyzed more than 468 billion DNS records, collected over 6 years, and identifed combosquatting domains. The researchers noted the number of domains being used for combosquatting has increased year over year.
The extent to which the attack method is being used is staggering. For just 268 trademarks, they identified 2.7 million combosquatting domains, which they point out makes combosquatting more than 100 times as common as typosquatting. While many of these malicious domains have been taken down, almost 60% of the domains were active for more than 1,000 days.
The team found these domains were used for a wide variety of nefarious activities, including affiliate abuse, phishing, social engineering, advanced persistent threats, malware and ransomware downloads.
End users are now being taught to carefully check domain names for typos and transposed letters to detect typosquatting, but this technique fools users into thinking they are on a website that is owned by the brand included in the domain.
First author of the study, Georgia Tech researcher Panagiotis Kintis, said, “These attacks can even fool security people who may be looking at network traffic for malicious activity. When they see a familiar trademark, they may feel a false sense of comfort with it.”
In order to prevent these types of trademark use attacks, many companies register hundreds of domains that contain their trademark. The researchers found that many of the domains being used by hackers had previously been owned by the holders of the trademark. When the domains were not renewed, they were snapped up by hackers. Many of the malicious domains that had been previously purchased by hackers, had been re-bought by other scammers when they came up for renewal.
Users are being lured onto the domains using a variety of techniques, including the placing of adverts with the combosquatting domains on ad-networks, ensuring those adverts are displayed on a wide variety of legitimate websites – a technique called malvertising. The links are also distributed in spam and phishing emails. These malicious URLS are also frequently displayed in search engine listings, and remain there until complaints are filed to have the domains removed.
Due to the prevalence of this attack technique, organizations should include it in their cyber awareness training programs to alert users to the attack method and ensure they exercise caution.
The researchers also suggest an organization should be responsible for taking these domains down and ensuring they cannot be re-bought when they are not renewed.

TitanHQ On the Road
It has been a busy few weeks for TitanHQ. The team has been traveling across Europe and the United States, showcasing its web filtering, spam filtering and email archiving solutions.
The Wi-Fi Now Europe 2017 comes hot on the heels of the DattoCon17 conference in London, where the team met with more than 400 MSPs and the ASCII Summit in Washington D.C., where TitanHQ explained how Managed Service Providers can grow their business and easily increase monthly recurring revenues. Earlier this month, TitanHQ attended the Kaseya Connect Europe IT Management Event and explained about the new integration of WebTitan with Kaseya.
The road trip continues into November in the United States, with TitanHQ attending both the upcoming HTG Meeting in Orlando, FL (Oct 30-Nov 3) and the IT Nation, ConnectWise Conference at the Hyatt Regency, Orlando, between November 8-10, 2017.
Last month saw a significant rise in healthcare data breaches, clearly demonstrating that healthcare providers, health plans, and business associates are struggling to prevent healthcare data breaches.
The Health Insurance Portability and Accountability Act (HIPAA) Security Rule was introduced to ensure that healthcare organizations implement a range of safeguards to ensure the confidentiality, integrity, and availability of healthcare data. It has now been more than decade since the Security Rule was introduced, and data breaches still occurring with alarming frequency. In fact, more data breaches are occurring than ever before.
September Data Breaches in Numbers
The Protenus Breach Barometer Report for September, which tracks all reported healthcare data breaches, showed there were 46 breaches of protected health information (PHI) in September, with those breaches resulting in the exposure of 499,144 individuals’ PHI. Hacking and IT incidents were cited as the cause of 50% of those breaches, with insiders causing 32.6% of incidents. Loss and theft of devices was behind almost 11% of the month’s breaches. Previous monthly reports in 2017 have shown that insiders are often the biggest cause of healthcare data breaches.
HIPAA Compliance Will Not Prevent Healthcare Data Breaches
HIPAA compliance can go some way toward making healthcare organizations more resilient to cyberattacks, malware and ransomware infections, but simply complying with the HIPAA Security Rule does not necessarily mean organizations will be impervious to attack.
HIPAA compliance is about raising the bar for cybersecurity and ensuring a minimum standard is maintained. While many healthcare organizations see HIPAA compliance as a goal to achieve a good security posture, the reality is that it is only a baseline. To prevent data breaches, healthcare organizations must go above and beyond the requirements of HIPAA.
Detect Insider Breaches Promptly
Preventing insider data breaches can be difficult for healthcare organizations. Healthcare employees must be given access to patient records in order to provide medical care, and there will always be the occasional bad apple that snoops on the records of patients who they are not treating, and individuals who steal data to sell to identity thieves.
HIPAA Requires healthcare organizations to maintain access logs and check those logs regularly for any sign of unauthorized access. The term ‘regularly’ is open to interpretation. A check every six months or once a year could be viewed as regular and compliant with HIPAA regulations. However, during those 6 or 12 months, the records of thousands of patients could be accessed. Healthcare organizations should go above and beyond HIPAA requirements and should ideally implement a system that constantly monitors for unauthorized access or at least conduct access log reviews every quarter as a minimum. This will not prevent healthcare data breaches, but it will reduce their severity.
Close the Door to Hackers
50% of breaches in September were due to hacking and IT incidents. Hackers are opportunistic, and while targeted attacks on large healthcare organizations do occur, most of the time hackers take advantage of long-standing vulnerabilities that have not been addressed. In order to correct those vulnerabilities, they must first be identified, hence the need for regular risk analyses as required by the HIPAA Security Rule. An organization-wide risk analysis should take place at least every year to remain HIPAA compliant, but more frequently to ensure vulnerabilities have not crept in.
Additionally, a check should be performed at least every month to make sure all software is up to date and all patches have been applied. There have been numerous examples recently of cloud storage instances being left unprotected and accessible by the public. There are free tools that can be used to check for exposed AWS buckets for example. Scans should be regularly conducted. Cybercriminals will be doing the same.
Prevent Impermissible Disclosures of PHI
One of the leading causes of PHI disclosures occurs when laptop computers, zip drives, and other portable devices are lost or stolen. While employees can be trained to take care of their devices, thieves will seize any opportunity if devices are left unprotected. HIPAA does not demand the use of encryption, and alternative measures can be used to secure devices, but HIPAA covered entities and their business associates should use encryption on portable devices to ensure that in the event of loss or theft, data cannot be accessed. If an encrypted device is stolen or lost, it is not a HIPAA breach. Using encryption on portable devices is a good way to prevent healthcare data breaches.
Small portable storage devices such as pen drives are convenient, but they should never be used for transporting PHI – They are far too easy to lose or misplace. Use HIPAA-compliant cloud storage services such as Dropbox or Google Drive as they are more secure.
Block Malware and Ransomware Attacks
Malware and ransomware attacks are reportable breaches under HIPAA, and can result in major data breaches. Email is the primary vector for delivering malware, so it is essential for an effective spam filtering solution to be implemented. HIPAA requires training to be provided to employees regularly, but a once-a-year training session is no longer sufficient. Training sessions should take place at least every 6 months, with regular security alerts on the latest phishing threats communicated to employees as and when necessary. Ideally, training should be an ongoing process, involving phishing simulation exercises.
Malware and ransomware can also be downloaded in drive-by attacks when browsing the Internet. A web filtering solution should be used to prevent healthcare employees from visiting malicious sites, to block phishing websites, and prevent drive-by malware downloads. A web filter is not a requirement of HIPAA, but it is an important extra layer of security that can prevent healthcare data breaches.
This week, the UK government’s Culture Secretary Karen Bradley announced the publication of a new green paper outlining the government’s Internet Safety Strategy, saying the aim is to make the UK the safest place to be online.
The Internet Safety Strategy outlines the awareness campaign that the government is taking to prevent cyber-bullying, trolling and the accessing of pornography by minors. The government has come under increasing pressure in recent years to take decisive action to curb the growing problem of online abuse and harm to minors from accessing age-inappropriate websites.
In a recent press release announcing the new Internet Safety Strategy, Bradley said “In the past year, almost one fifth of 12-15-year olds encountered something online that they ‘found worrying or nasty in some way’ and 64% of 13-17-year olds have seen images or videos offensive to a particular group.” The problem is not confined to minors. Adults too have been offended or upset by material they have viewed on social media sites, and the new strategy will also help to keep adults safe and protected online.
The aim of the new proposals is not censorship of the Internet – the UK government continues “to embrace the huge benefits and opportunities the Internet has brought for British citizens.” The aimof the government’s Internet Safety Strategy is simply to make the Internet a safer place and prevent harm to vulnerable people, especially children.
Bradley said, “Behaviour that is unacceptable in real life is unacceptable on a computer screen. We need an approach to the Internet that protects everyone without restricting growth and innovation in the digital economy.”
The Internet Safety Strategy tackles a range of online issues using several different methods – a combination of improved efforts to educate children and the public about online dangers and acceptable online conduct, social media advice, the promotion of safety features for parents to use to protect their children, and the use of Internet filtering in schools.
Some of the key elements in the Internet Safety Strategy are:
Developing a new social media code of practice to address bullying, intimidating, or humiliating online content
An industry-wide levy so social media companies and communication service providers contribute to raise awareness and counter internet harms
The publication of an annual Internet safety transparency report detailing the progress made at reducing abusive and harmful content and conduct
Providing support for start-ups and tech companies to help them build safety features into their products and apps at the design stage
Compulsory new subjects in schools: Relationship education at the primary school level and relationship & sex education at secondary level
Encouraging social media companies to provide social media safety advice to parents and build that advice into their platforms
Promoting the use of social media and Internet safety features by parents
Changing the name of the UK Council for Child Internet Safety to the UK Council for Internet Safety, to show the safety of all Internet users is of concern
In the new green paper, the Keeping Children Safe in Education (KCSIE) guidance is highlighted. The guidance details the steps that schools and colleges in England should take to protect students and keep them safe online. The guidance was updated in September last year to include a new section on safeguarding children online. Schools were reminded of their responsibility to prevent children from accessing harmful and inappropriate website content, explaining Internet filtering in schools is a requirement. Solutions that allow Internet filtering in schools should block inappropriate content and also allow the monitoring of the attempted access of inappropriate material.
The use of similar controls by parents is being encouraged, first by making sure the options are available – the big four ISPs in the UK all offer Internet content filtering controls – and to improve education on the need to implement content filtering solutions to protect children at home.
Vicki Shotbolt, Chief Executive Officer at Parent Zone – an organization set up to provide expert information to families, schools and family professionals on the Internet safety – said, “It is encouraging to see the government proposing concrete steps to ensure that industry is doing everything they can to support families and make the Internet a place that contributes to children flourishing.”
There has been a rapid evolution of ransomware over the past two years. New variants of ransomware are now being released on an almost daily basis, and the past two years have seen a massive explosion in new ransomware families. Between 2015 and 2016, Proofpoint determined there had been a 600% increase in ransomware families and Symantec identified 100 totally new ransomware families in 2016.
The development of new ransomware variants has largely been automated, allowing developers to massively increase the number of threats, making it much harder for the developers of traditional, signature-based security solutions such as antivirus and antimalware software to maintain pace.
The latest ransomware variants use a wide variety of techniques to evade detection, with advanced obfuscation methods making detection even more problematic.
Ransomware is also becoming much more sophisticated, causing even greater problems for victims. Ransomware is now able to delete Windows Shadow Volume copies, hampering recovery. Ransomware can interfere with file activity logging, making an infection difficult to detect until it is too late. Ransomware can encrypt files on removable drives – including backups – and spread laterally on a network, encrypting files on network shares and multiple end points.
Not only have the ransomware variants become more sophisticated, so too have the methods for distributing the malicious code. Highly sophisticated spam campaigns use a variety of social engineering techniques to fool end users into visiting malicious links and opening infected email attachments. Droppers with heavily obfuscated code are used to download the malicious payload and a considerable amount of effort is put into crafting highly convincing emails to maximize the probability of an end user taking the desired action.
Then, there is ransomware-as-a-service – the use of affiliates to spread ransomware in exchange for a cut of the profits. Ransomware kits are now supplied, complete with intuitive web based interfaces and instructions for crafting ransomware campaigns. Today, it is not even necessary to have any technical skill to conduct a ransomware campaign.
The profits from ransomware are also considerable. In 2016, the FBI estimated profits from ransomware would exceed $1 billion. With such high returns, it is no surprise that ransomware has become the number one malware threat for businesses.
The Evolution of Ransomware – Notorious Ransomware Variants from the Past Two Years
Locky: Deletes volume shadow copies from the compromised system, thereby preventing the user from restoring files without paying the ransom.
Jigsaw: An extremely aggressive ransomware variant that deletes encrypted files every hour until the ransom is paid, with total file deletion in 72 hours.
Petya: Rather than encrypting files, Petya changes and encrypts the master boot record, preventing files from being accessed. Petya is also capable of installing other malware payloads.
NotPetya: A wiper that appears to be ransomware, although NotPetya permanently changes the master boot record making file recovery impossible.
CryptMix: Attackers claim they will donate the ransom payments to a children’s charity, in an effort to get victims to pay up. There is no evidence ransom payments are directed to worthy causes.
Cerber: Now used to target users of cloud-based Office 365, who are less likely to have backed up their data. Some Cerber variants speak to their victims and tell them their files have been encrypted.
KeRanger: One of the first ransomware strains to target Mac OS X applications.
Gryphon: Spread via remote desktop protocol (RDP) using brute force tactics to guess weak passwords.
TorrentLocker: A ransomware variant being used to target SMBs, spread via spam email attachments claiming to be job applications
HDDCryptor: A ransomware variant that targets network shares, file, printers, serial ports, and external drives. HDDCryptor locks the entire hard disk
CryptMIC: A ransomware variant that does not change file extensions, making it harder for victims to identify the threat
ZCryptor: Ransomware with worm-like capabilities, able to rapidly spread across a network and infect multiple networked devices and external drives
WannaCrypt: A 2017 ransomware variant with worm-like capabilities, able to spread rapidly to infect all vulnerable computers on a network.
Ransomware is most commonly spread via spam email, exploit kits and by remotely exploiting vulnerabilities. To protect against ransomware you need an advanced spam filter, a web filter such as WebTitan to block access to sites containing exploit kits, and you need to ensure software and operating systems are kept 100% up to date.
In the event that you are infected with ransomware, you must be able to recover files from a backup. Use the 321 approach to ensure you can recover files without paying the ransom – Make three backup copies, on two different media, with one copy stored securely off site. Also make sure backups are tested to ensure files can be restored in an emergency.
Cybercriminals have realized they can greatly increase the number of infections – and profits – by adopting an affiliate model – termed ransomware-as-a-service. The affiliate model works well for online retailers, who can generate sales from customers they would be unlikely to reach if they worked on their own. The same applies to ransomware developers.
Affiliates are recruited to distribute ransomware in exchange for a cut of the profits. Ransomware developers can recruit would-be cybercriminals to send out their malicious code in targeted attacks around the world, extending their reach considerably. The greater the number of affiliates, the wider ransomware can be spread and the more payments are received. The returns are substantial for relatively little effort.
In addition to developing the ransomware, kits have been created that make it simple for affiliates to launch their own campaigns. No technical skill is required, affiliates simply enter in their own parameters via an online interface and they can start conducting their own campaigns. Affiliates just need to know how to distribute the ransomware. Full instructions are usually provided.
With an army of spammers sending out the ransomware, the number of devices infected has soared. In 2017, Cerber became the most widely used ransomware variant, even surpassing Locky. The secret of the success was adopting the ransomware-as-a-service model.
For the most part, ransomware is a numbers game. The more individuals that are actively distributing ransomware, the greater the number of infections. With the threat of email and web-based attacks growing, businesses must invest in new technologies to counter the threat.
There are two key solutions that should be adopted by all businesses to improve protections against ransomware. A spam filter is a must – a fact not lost on the majority of businesses. However, even though email is the primary vector used to spread ransomware and malware, there are still businesses that have not yet purchased a spam filtering solution.
A recent survey by PhishMe indicates only 85% of businesses are using spam filtering technology to block phishing emails. That means 15% of businesses have yet to implement this most fundamental of ransomware defenses.
The second key solution is a web filter. Web filters allow employers to carefully control the websites that their employees can access, including blocking websites known to host malware. If an email makes it past a spam filter and an employee clicks on a malicious hyperlink, a web filter can prevent the malicious site from being accessed. A web filter also offers protection from malvertising – malicious adverts that direct users to phishing websites and sites hosting exploit kits.
Of course, technology can only go so far. Even layered defenses can be breached, which is why employees need to be taught how to identify potentially malicious emails. Employees should receive regular security awareness training and be encouraged to report potentially malicious emails. When those emails are reported, IT teams can add the malicious links to the web filter to prevent other individuals in the organization from visiting the malicious websites.

Popup warnings of missing fonts, specifically the Hoeflertext font, are being used to infect users with malware. The Hoeflertext warnings appear as popups when users visit compromised websites using the Chrome or Firefox browsers. The warnings flash up on screen with the website in the background displaying jumbled or unreadable text.
Hoeflertext is a legitimate font released by Apple in 1991, although popup warnings that the font is missing are likely to be a scam to fool users into downloading Locky Ransomware or other malware.
Visitors to the malicious websites are informed that Hoeflertext was not found, which prevents the website from being displayed. The popup contains an option to “update” the browser with a new font pack, which will allow the website content to be displayed.
This is not the first time the Hoeflertext font scam has been used. NeoSmart Technologies discovered the scam in February this year, although recently both Palo Alto Networks and SANS Internet Storm Center have both report it is being used in a new campaign.
Another version of the campaign is being used to deliver the NetSupport Manager remote access tool (RAT). In this case, the file downloaded is called Font_Chrome.exe, which will install the RAT if it is run. The researchers suggest the RAT is being favored as it offers the attackers a much wider range of capabilities than ransomware. The RAT is commercially available and has been used in several malware campaigns in the past, including last year’s campaign using hacked Steam accounts.
The RAT, once installed, gives the attackers access to the infected computer allowing them to search for and steal sensitive information and download other malware.
The actors behind this campaign have been using spam email to direct users to the malicious websites where the popups are displayed. The SANS Internet Storm Center says one campaign has been identified using emails that appear to have been sent via Dropbox, asking the user to verify their email address to complete the sign-up process.
Clicking on the ‘verify your email’ box will direct the user to a malicious website displaying fake Dropbox pages where the popups appear. Internet Explorer users do not have the popups displayed, instead they are presented with a fake anti-virus alerts linked to a tech support scam.
The latest campaign shows why it is so important for businesses to use an advanced spam filtering solution to block malicious messages. A web filtering solution is also beneficial to prevent end users from visiting malicious websites in case the messages are delivered and opened. Along with security awareness training for employees to alert them to the risks of email and web-based attacks such as this, businesses can protect themselves from attack.
With the volume of cyberattacks increasing and heightened pressure on businesses to offer family-friendly WiFi access, a partnership with a company that offers Internet filtering for managed service providers is now a must.
Businesses that offer WiFi access to customers provide greater value and are more likely to attract customers. Younger age groups in particular are more likely to choose an establishment that allows them to connect to the Internet and not use their own data allowance. Coffee shops, restaurants, bars, and retail outlets now appreciate that providing WiFi access brings in more customers.
However, it is becoming increasingly important for secure WiFi access to be provided. Customers are now demanding more. They want reassurance that efforts are being made to make WiFi networks secure. Parents also want to make sure their children will not be exposed to harmful website content when hooking up to WiFi networks.
With demand for a filtered Internet service high, it is an easy sell for managed service providers. Further, Internet filtering brings in regular monthly revenue for next to no effort. Once the service is set up there is very little maintenance. Due to the low maintenance overhead and ease of implementation, Internet filtering for managed service providers could even be provided as part of an existing security suite to give clients even greater value for money.
Visiting clients to install solutions and perform updates is costly and eats into profits. It can also be difficult to convince businesses to pay out for an appliance to keep customers safe online. Free WiFi may increase footfall, but having to pay for a $500 appliance is a difficult sell.
However, with a cloud-based filter there is no need for any hardware purchases, no need for MSPs to visit their clients for an installation, and all settings can be changed remotely via an online administration control panel. Customers can even be given their own logins so they can tweak their own settings and whitelist and blacklist certain webpages at will.

From May 25, 2018, all companies doing business with EU residents must comply with the General Data Protection Regulation (GDPR), but how can companies protect personally identifiable information under GDPR and avoid a penalty for non-compliance?
The General Data Protection Regulation
GDPR is a new regulation in the EU that will force companies to implement policies, procedures and technology to improve the privacy protections for consumers. GDPR also gives EU citizens more rights over the data that is recorded and stored by companies.
GDPR applies to all companies that do business with EU citizens, regardless of whether they are based in the EU. That means a company with a website that can be accessed by EU residents would be required to comply with GDPR.
Personally identifiable information includes a wide range of data elements relating to consumers. Along with the standard names, addresses, telephone numbers, financial and medical information, the GDPR definition includes IP addresses, logon IDs, videos, photos, social media posts, and location data – essentially any information that is identifiable to a specific individual.
Policies must be developed covering data subjects (individuals whose data is collected), data controllers (organizations collecting data) and data processors (companies that process data). Records must be maintained on how data is collected, stored, used and deleted when no longer required.
Some companies are required to appoint a data protection officer (DPO) whose role is to ensure compliance with GDPR. That individual must have a thorough understanding of GDPR, and technical knowledge of the organization’s processes and procedures and structure.
In addition to ensuring data is stored securely and consumers have the right to have their stored data deleted, GDPR will also force companies to disclose data breaches quickly – within 72 hours of a breach being discovered.
Failure to comply with GDPR could result in a heavy fine. Fines of up to €20,000,000 or 4% of a company’s annual revenue are possible, whichever is the greater.
Many companies are not prepared for GDPR or think the regulation does not apply to them. Others have realized how much work is required and have scrambled to get their businesses compliant before the deadline. For many companies, the cost of compliance has been considerable.
How Can I Protect Personally Identifiable Information under GDPR?
GDPR imposes a number of restrictions on what companies can and cannot do with data and how it must be protected, although there are no specific controls that are required of companies to protect personally identifiable information under GDPR. The technology used to protect data is left to the discretion of each company. There is no standard template to protect personally identifiable information under GDPR.
A good place to start is with a review of the processes and systems that collect and store data. All data must be located before it can be protected and systems and processes identified to ensure appropriate controls are applied.
GDPR includes a right to be forgotten, so all data relating to an individual must be deleted on request. It is therefore essential that a company knows where all data relating to an individual is located. Controls must also be put in place to restrict the individuals who have access to consumer data. Training must also be provided so all employees are aware of GDPR and how it applies to them.
Companies should perform a risk assessment to determine their level of risk. The risk assessment can be used to determine which are the most appropriate technologies to implement.
Technologies that allow the pseudonymisation and encryption of data should be considered. If data is stored in encrypted form, it is not classed as personal data any more.
Companies must consider implementing technology that improves the security of systems and services that process data, mechanisms that allow data to be restored in the event of a breach, and policies that regularly test security controls.
To protect personally identifiable information under GDPR, organizations must secure all systems and applications used to store or process personal data and have controls in place to protect IT infrastructure. Systems should also be implemented that allow companies to detect data breaches in real time.
Compliance with GDPR is not something that can be left to the last minute. May 25 is a long way off, but given the amount of work involved in compliance, companies need to be getting to grips with GDPR now.
The National Institute of Standards and Technology (NIST) has updated its guidance on strengthening passwords, suggesting the standard of using a combination of capital letters, lower case letters, numbers and special characters may not be effective at improving password strength. The problem is not with this method of strengthening passwords, but with end users.
Hackers and other cybercriminals attempt to gain access to accounts by guessing passwords. They try many different passwords until the correct one is guessed. This process is often automated, with many thousands of guesses made using lists of commonly used passwords, dictionary words and passwords discovered from past data breaches.
By implementing password policies that force end users to use strong passwords, organizations can improve their resilience against these brute force attacks.
By using capital and lower-case letters, there are 52 possible options rather than 26, making the guessing process much more time consuming. Add in 10 numerals and special characters and guessing becomes harder still. There is no doubt that this standard practice for creating strong passwords is effective and makes passwords much less susceptible to brute force attacks.
The problem is that in practice, that may not be the case. Creating these strong passwords – random strings of letters, numbers and symbols – makes passwords difficult to guess but also virtually impossible to remember. When multiple passwords are required, it becomes harder still for end users and they get frustrated and cut corners.
A good example is the word ‘password’, which is still – alarmingly – used to secure many accounts, according to SplashData’s list of the worst passwords of the year. Each year, ‘password’ makes it onto the list, even though it is likely to be the first word attempted in any brute force attack.
When companies update their password polices forcing users to use at least one capital letter and number in a password, many end users choose Password1, or Passw0rd or P455w0rd. All would be high up on a password list used in a brute force attack.
Attempts such as these to meet company password requirements mean security is not actually improved by password policies. If this is going to happen, it would make more sense – from a security perspective – to allow employees to make passwords easier to remember in a more secure way.
NIST Tweaks its Guidance on Strengthening Passwords
As NIST points out in its guidance on strengthening passwords, “Analyses of breached password databases reveal that the benefit of such rules is not nearly as significant as initially thought.” With current standard password practices, “The impact on usability and memorability is severe.” That results in end users creating weak passwords that meet company password policies.
Rather than force end users to use special characters and end up with ‘Password!’, a better way would be to increase the length of passwords and allow the use of spaces. End users should be encouraged to choose easy to remember phrases.
The use of a space does not make a password any more secure, although increasing a password from 8 characters to say, 15 or 20 characters, certainly does. It also makes passwords much easier to remember. NIST suggests passwords must have a minimum of 8 characters, and that “Users should be encouraged to make their passwords as lengthy as they want, within reason.”
NIST also explains in its guidance on strengthening passwords that certain types of common cyberattacks involving passwords are unaffected by password strength. Take phishing for instance. It doesn’t matter whether a password is ‘12345678’ or ‘H19g46”&”^’ to a phisher. Provided the phishing email is well crafted, the password will still be disclosed. The same applies to keyloggers. A keylogger logs keystrokes and the strength of the password is irrelevant.
NIST’s guidance on strengthening passwords also suggests that rather than strengthening passwords further, there are far more effective ways of making brute force attacks much harder without frustrating end users. Limiting the number of failed login attempts before a user is blocked is one such option. Organizations should also combine this with blacklists of unacceptable passwords that should include dictionary words, other weak passwords and those revealed from past data breaches. NIST also recommends secured hashed storage of passwords
The importance of implementing good patch management policies was clearly highlighted by the WannaCry ransomware attacks in May. The ransomware attacks were made possible due to poor patch management policies at hundreds of companies. The attackers leveraged a vulnerability in Windows Server Message Block (SMB) using exploits developed by – and stolen from – the U.S. National Security Agency.
The exploits took advantage of SMB flaws that had, by the time the exploits were made public, been fixed by Microsoft. Fortunately for the individuals behind the attacks, and unfortunately for many companies, the update had not been applied.
In contrast to the majority of ransomware attacks that required some user involvement – clicking a link or opening an infected email attachment – the SMB flaws could be exploited remotely without any user interaction.
WannaCry was not the only malware variant that took advantage of unpatched systems. The NotPetya (ExPetr) attacks the following month also used the same EternalBlue exploit. Again, these attacks required no user involvement. NotPetya was a wiper that was used for sabotage and the damage caused by those attacks was considerable. Entire systems had to be replaced, companies were left unable to operate, and the disruption continued for several weeks after the attacks for many firms. For some companies, the losses from the attacks were in the millions.
These attacks could have easily been prevented with something as simple as applying a single patch – MS17-010. The patch was available for two months prior to the WannaCry attacks. Even patch management policies that required software to be checked once a month would have prevented the attacks. In the case of NotPetya, companies affected had also not reacted to WannaCry, even though there was extensive media coverage of the ransomware attacks and the risk of not patching promptly was clearly highlighted.
The take home message is unaddressed security vulnerabilities will be exploited. Companies can purchase a swathe of expensive security solutions to secure their systems, but companies with poor patch management policies will experience data breaches. It is no longer a case of if a breach will occur, just a matter of when.
Poor Patch Management Policies Cost Insurer More than $5 Million
This month has shown another very good reason for patching promptly. A multi-state action by attorneys general in 32 states has resulted in a settlement with Nationwide Mutual Insurance Company and its subsidiary, Allied Property & Casualty Insurance Company. Nationwide has agreed to a $5.5 million settlement to resolve the investigation into its 2012 data breach.
The breach involved the theft of data relating to 1.27 million policy holders and individuals who obtained insurance quotes from the company. In that case, the data theft was possible due to an unaddressed vulnerability in a third-party application. Even though the vulnerability was rated as critical, the insurer did not update the application. The vulnerability remained unaddressed for three years. The update was only applied after data were stolen.
The investigation into the breach was jointly led by Connecticut Attorney General George Jepsen. Announcing the settlement Jepsen said, “It is critically important that companies take seriously the maintenance of their computer software systems and their data security protocols.”
Unaddressed vulnerabilities will be exploited by cybercriminals. Attacks will result in data theft, hardware damage, law suits filed by breach victims, attorneys general fines and fines by other regulators. These costs can all be avoided with good patch management policies.
There are many reasons why businesses want to restrict internet access at work. Allowing employees to have unrestricted access to the internet can result in a major drain of productivity. Unfettered internet access can also increase the risk of malware and ransomware downloads, while inappropriate internet access at work can lead to a range of legal issues. Due to the risks involved, it is unsurprising that many firms choose to use a technological solution to enforce acceptable internet usage policies and block access to malicious websites. This post explores some of the key benefits that come from using a web filter to limit internet access in the workplace and some of the potential problems that can be caused by using content control software.
The Problem of Personal Internet Use at Work
It is inevitable that employees will slack off from time to time, regardless of whether they have access to the internet but internet access makes slacking off much easier. Simply placing restrictions on the websites that can be accessed will not eradicate time wasting, but it can allow businesses to make significant gains in productivity. Some employees spend a considerable percentage of the working day on personal internet use, playing online games, or accessing their social media accounts. If every employee in an organization was to spend an hour a day on personal internet use, the productivity losses would be considerable. A company with 100 employees would lose 100 hours a day – That’s a loss of 26,100 working hours a year – and many employees spend much longer each day on personal internet use.
There are other issues that can result from excessive personal internet use at work. When employees use streaming services, download files via P2P networks, or engage in other bandwidth heavy activities, it will naturally have an impact on internet speeds across the entire organization. Using a web filter to restrict internet access at work and limiting access to certain bandwidth draining activities allows businesses to ensure sufficient bandwidth is available for all employees.
The Danger of Malware and Ransomware Downloads
If employees are accessing social media websites, downloading files, or are visiting questionable websites, the risk of a malware or ransomware downloads increases significantly.
Exploit kits probe for vulnerabilities in browsers and plugins, which are then exploited to silently download malware. Traffic is usually directed to these websites through malicious adverts – termed malvertising – although high traffic websites are constantly being compromised by hackers who add malicious content such as phishing webpages and malware.
Certain types of website carry a high risk of resulting in a malware infection. Allowing employees to access to these sites, many of which are not suitable for work, could easily result in a malware or ransomware download.
The operators of legitimate pornographic websites usually take great care to ensure their sites are not compromised or infected with malware. They are, after all, legitimate businesses. However, pornographic content is often used as a lure to spread malware and there are many disreputable adult sites whose purpose is solely to infect visitors with malware or harvest credit card information. Blocking these NSFW sites not only helps to improve productivity and avoid legal issues, it reduces the risk of malware infections.
One of the riskiest online activities is the use of torrents sites and P2P file sharing networks. There are few – if any – controls over the content that is shared via torrents sites and pirated music and video files are often seeded with malware, spyware, and adware. Illegal software downloads are incredibly risky as malware is often bundled in the executable files used to install the software, or in the accompanying Keygen tools that generate product keys to allow the software to be used.
A malware or ransomware attack can prove incredibly costly. Many companies have experienced ransomware attacks that have resulted in systems being taken out of action for several days or even weeks, causing massive losses as the business grinds to a halt. A ransomware attack can result in an entire network being taken out of action, as was the case with the WannaCry attacks in 2017. The NHS in the UK suffered major disruption as a result of the installation of the malware and mitigating the attacks cost £92 million. The NotPetya wiper malware campaign conducted soon after caused widespread damage. The shipping firm Maersk had its systems infected and the clean up bill has been estimated to be $300 million.
A web filter will not prevent all malware and ransomware attacks, but it is possible to prevent certain categories of ‘risky’ website from being visited by employees, the filtering solution can be configured to block the downloading of certain file types, and websites known to contain malware or exploit kits can be blocked. Any attempt to visit one of those websites will direct a user to a block screen. Many businesses decide to restrict internet access at work primarily to protect against malware and ransomware downloads.
A Web Filter Offers Additional Protection Against Phishing Attacks
Phishing is the number one cyber threat faced by businesses. It has been estimated that more than 90% of cyberattacks start with a phishing email. One of the best protections against phishing is a spam filtering solution, which will prevent the majority of malicious messages from being delivered to end users. However, no spam filter is 100% effective and some malicious messages will end up in employees’ inboxes. Employees can be trained how to identify phishing emails and be taught cybersecurity best practices that will reduce susceptibility to phishing attacks, but sooner or later an employee will likely be fooled into clicking a link in an email and will arrive at a phishing website.
When a user is directed to a website and discloses their login credentials, an attacker can gain access to their email account and all the sensitive data contained in that account. The compromised account can also be used to send further phishing emails to other employees in the organization or to customers and business contacts. It is common for a single response to a phishing email to result in several email accounts being compromised.
Phishing attacks are some of the costliest cyberattacks to resolve. Each email in a compromised account must be checked for personally identifiable information and other sensitive data. Manually checking thousands of emails can take weeks and can cost hundreds of thousands of dollars.
A web filter is an additional layer of security that helps organizations improve their defenses against phishing by providing time-of-click protection and blocking attempts to visit malicious websites. When an employee clicks a link to a website that has been added to a blacklist due to past use in phishing campaigns, the user will be directed to a block screen. TitanHQ’s web filtering solution, WebTitan, blocks attempts to access around 60 million malicious websites a week.
Preventing Inappropriate Web Content from Being Accessed
While most employees do not use the internet to access illegal and not-suitable-for-work content, there are always a few bad apples. The problem of accessing pornography at work is a real issue, and could be much worse than you think.
In 2014, a survey conducted by the Barna Group showed 63% of men and 36% of women have viewed pornography at work. A survey in Forbes in 2013 revealed 25% of adults have viewed porn at work, while in another survey, 28% of employees admitted to downloading porn at work. Not only is the accessing of pornography at work a major drain of productivity, it can lead to the development of a hostile working environment. Pornography can be used to harass and degrade employees, especially women. There have been cases of employees taking legal action against their employers over the failure to implement content controls in the workplace and prevent pornography from being accessed by coworkers.
Many businesses feel the best way to tackle the problem of pornography access in the workplace is through acceptable usage policies and greater oversight of employees by line managers. When individuals are discovered to be abusing the internet, action can be taken against individuals without having to restrict internet access at work for everyone. This does not always prove effective. Further, when pornography use at work is discovered, employees usually face instant dismissal. That carries a cost to to the HR department and productivity losses while new employees are hired and trained.
The easiest solution is is to use a web filter to restrict internet access at work. A web filter can be used to block access to specific websites or categories of website content such as pornographic sites and enforce acceptable usage policies. This is one of the most common reasons why businesses restrict internet access at work.
Problems with Using a Web Filter to Restrict Internet Access at Work
A web filter may seem like a quick and easy solution to solve the above issues, but it should be explained that companies that restrict internet access at work with web filters can encounter problems. If you restrict internet access at work using an appliance-based web filtering solution it can result in latency. Each website must be inspected before it is accessed which delays the loading of websites. In the case of secure (HTTPS) sites, each webpage must be decrypted, inspected, and re-encrypted. This places a considerable strain on resources. As more sites switch to HTTPS the problem of latency becomes a real issue.
The solution is to use a DNS-based filtering solution. With DNS-filtering, all filtering occurs in the cloud and there is no latency. There are other benefits too. Cloud-based web filters are more flexible, scalable, and do not require the purchase of any hardware which results in considerable cost savings.
When web filters are used to restrict internet access at work and they lack highly granular controls, there can be issues with the overblocking of website content. Websites that need to be accessed for work purposes may be blocked, which requires the IT support team to spend time whitelisting websites. The solution is to choose a web filter with highly granular controls, which allows content to be easily blocked without also blocking websites that need to be accessed for work purposes.
Should Companies Restrict Internet Access?
While content control software may seem like an ideal way of preventing employees from cyberslacking to make productivity gains, care must be taken when applying those controls otherwise the productivity gains may not be realized. If you restrict internet access at work, employees who were only accessing the occasional personal site may be unhappy with the new restrictions. This can have a negative effect on productivity and create a hostile working environment. Why should all employees be made to suffer because of the actions of a few? Care must therefore be taken when deciding what types of website to block. With careful and intelligent control, you can make productivity gains and can avoid any staff issues.
How to Control Internet Usage in Office and Avoid Staff Problems
One of the easiest ways to improve productivity while applying controls over internet access is to use a web filtering solution that allows time-based filtering controls to be applied. Employers can use this feature to restrict internet access at work during busy times and relax controls at others. It is easy to block access to certain sites 100% of the time and others only some of the time. With WebTitan, administrators can set standard controls during busy times such as mornings, and relax controls during breaks or outside of office hours.
How Can I Block Internet Access on an Employee’s Computer?
There are several ways to block internet access on an employee’s computer. If you want to block internet access totally for a specific employee, be that a temporary or permanent block, you can use your existing network hardware or a firewall rule to block a specific IP address.
A web filter allows much more granular controls to be applied, such as blocking specific websites or categories of website for a specific employee or group of employees. This option is much easier and less time consuming if you need to block internet access – or implement partial blocks – for more than one employee. With a cloud-based web filter, these controls can be applied quickly and easily through a web portal that can be accessed by the administrator from any computer.
How to Limit Employee Internet Access Selectively
Many businesses want to know how to restrict internet access for employees without totally blocking access to the internet. With WebTitan it is easy to limit employee internet access selectively. Different controls can be set for different employees or groups of employees. If you have sales staff, you may want to do as much as possible to make sure they are always on the phone and internet controls may need to be more restrictive. The marketing department may require much more lax controls since they will be required to access a broader range of websites for work. Since the filter integrates with LDAP and Active Directory, setting controls for different users and user groups is simple. You can implement organization-wide controls (e.g. adult content), department controls (social media), and individuals controls through LDAP/AD.

2017 has seen a major rise in malware attacks on schools. While cybercriminals have conducted attacks using a variety of different malware, one of the biggest problems is ransomware. Ransomware is malicious code that encrypts files, systems and even master file tables, preventing victims from accessing their data. The attack is accompanied by a ransom demand. Victims are required to pay a ransom amount per infected device. The ransom payments can range from a couple of hundred dollars to more than a thousand dollars per device. Ransom demands of tens of thousands of dollars are now common.
Data can be recovered from a backup, but only if a viable backup of data exists. All too often, backup files are also encrypted, making recovery impossible unless the ransom is paid.
Ransomware attacks can be random, with the malicious code installed via large-scale spam email campaigns involving millions of messages. In other cases, schools are targeted. Cybercriminals are well aware that cybersecurity defenses in schools are often poor and ransoms are more likely to be paid because schools cannot function without access to their data.
Other forms of malware are used to record sensitive information such as login credentials. These are then relayed back to the attackers and are used to gain access to school networks. The attackers search for sensitive personal information such as tax details, Social Security numbers and other information that can be used for identity theft. With ransomware, attacks are discovered immediately as ransom notes are placed on computers and files cannot be accessed. Keyloggers and other forms of information stealing malware often take many months to detect.
Recent malware attacks on schools have resulted in entire networks being sabotaged. The NotPetya attacks involved a form of malware that encrypts the master file table, preventing the computer from locating stored data. In this case, the aim of the attacks was to sabotage critical infrastructure. There was no way of recovering the encrypted MFT apart from with a full system restore.
The implications of malware attacks on schools can be considerable. Malware attacks on schools result in considerable financial losses, data can be lost or stolen, hardware can be rendered useless and educational institutions can face prosecution or law suits as a result of attacks. In some cases, schools have been forced to turn students away while they resolve infections and bring their systems back online.
Major Malware Attacks on Schools in 2017
Listed below are some of the major malware attacks on schools that have been reported in 2017. This is just a very small selection of the large number of malware attacks on schools in the past 6 months.
Minnesota School District Closed for a Day Due to Malware Attack
Malware attacks on schools can have major consequences for students. In March, the Cloquet School District in Minnesota experienced a ransomware attack that resulted in significant amounts of data being encrypted, preventing files from being accessed. The attackers issued a ransom demand of $6,000 for the keys to unlock the encryption. The school district is technology-focused, so without access to its systems, lessons were severely disrupted. The school even had to close for the day while IT support staff restored data. In this case, sensitive data were not compromised, although the disruption caused was severe. The ransomware is understood to have been installed as a result of a member of staff opening a phishing email that installed the ransomware on the network.
Swedesboro-Woolwich School District Suffers Cryptoransomware Attack
The Swedesboro-Woolwich School District in New Jersey comprises four elementary schools and has approximately 2,000 students. It too suffered a crypto-ransomware attack that took its computer systems out of action. The attack occurred on March 22, resulting in documents and spreadsheets being encrypted, although student data were apparently unaffected.
The attack took a significant part of the network out of action, including the District’s internal and external communications systems and even its point-of-sale system used by students to pay for their lunches. The school was forced to resort to pen and paper while the infection was removed. Its network administrator said, “It’s like 1981 again!”
Los Angeles Community College District Pays $28,000 Ransom
Ransomware was installed on the computer network of the Los Angeles County College District, not only taking workstations out of action but also email and its voicemail system. Hundreds of thousands of files were encrypted, with the incident affecting most of the 1,800 staff and 20,000 students. A ransom demand of $28,000 was issued by the attackers. The school had no option but to pay the ransom to unlock the encryption.
Calallen Independent School District Reports Ransomware Attack
The Calallen Independent School District in northwestern Corpus Christi, TX, is one of the latest victims of a ransomware attack. In June, the attack started with a workstation before spreading to other systems. In this case, no student data were compromised or stolen and the IT department was able to act quickly and shut down affected parts of the network, halting its spread. However, the attack still caused considerable disruption while servers and systems were rebuilt. The school district also had to pay for improvements to its security system to prevent similar attacks from occurring.
Preventing Malware and Ransomware Attacks on Schools
Malware attacks on schools can occur via a number of different vectors. The NotPetya attacks took advantage of software vulnerabilities that had not been addressed. In this case, the attackers were able to exploit the vulnerabilities remotely with no user interaction required. A patch to correct the vulnerabilities had been issued by Microsoft two months before the attacks occurred. Prompt patching would have prevented the attacks.
Software vulnerabilities are also exploited via exploit kits – hacking kits loaded on malicious websites that probe for vulnerabilities in browsers and plugins and leverage those vulnerabilities to silently download ransomware and malware. Ensuring browsers and plugins are 100% up to date can prevent these attacks. However, it is not possible to ensure all computers are 100% up to date, 100% of the time. Further, there is usually a delay between an exploit being developed and a patch being released. These web-based malware attacks on schools can be prevented by using a web filtering solution. A web filter can block attempts by end users to access malicious websites that contain exploit kits or malware.
By far the most common method of malware delivery is spam email. Malware – or malware downloaders – are sent as malicious attachments in spam emails. Opening the attachments results in infection. Links to websites that download malware are also sent via spam email. Users can be prevented from visiting those malicious sites if a web filter is employed, while an advanced spam filtering solution can block malware attacks on schools by ensuring malicious emails are not delivered to end users’ inboxes.

Providing free WiFi in shops helps to attract more foot traffic and improves the shopping experience, although retailers are now realizing the benefits of providing secure WiFi access for shops. Over the past two years, there has been considerable media coverage of the dangers of public WiFi hotspots. Consumer websites are reporting horrifying cases of identity theft and fraud with increasing regularity.
With public awareness of the risks of connecting to public WiFi networks now much greater than ever before, secure WiFi access for shops has never been more important. Consumers now expect free WiFi access in shops, but they also want to ensure that connecting to those WiFi networks will not result in a malware infection or their personal information being obtained by hackers.
Fortunately, there are solutions that can easily be adopted by retailers that mitigate the risks and ensure consumers can connect to WiFi networks safely, but before we cover those options, let’s look a little more closely at the risks associated with unsecured WiFi networks.
The Risks of Unsecured WiFi Networks
If retailers provide free WiFi access in store it helps to attract more foot traffic, individuals are encouraged to stay in stores for longer, they have access to information and reviews about products and studies have shown that customers spend more when free WiFi is provided. A survey by iGT, conducted in 2014, showed that more than 6 out of ten customers spend longer in shops that provide WiFi access and approximately 50% of customers spend more money.
Connecting to a public WiFi network is different from connecting to a home network. For a start, considerably more people connect, including individuals who are intent on stealing information for identity theft and fraud. Man-in-the-middle attacks are common. Man-in-the-middle attacks involve a hacker intercepting or altering communications between a customer and a website. If login details or other sensitive information is entered, a hacker can obtain that information.
Malware and ransomware can be downloaded onto users’ devices and phishing websites can easily be accessed if secure WiFi access for shops is not provided. Consumers typically have Internet security solutions in place on home networks that block these malicious websites. They expect the same protections on retailers’ WiFi networks. Malware poses a significant threat. Alcatel-Lucent, a French telecommunications company, reports that malware attacks on mobile devices are increasing by 25% per year.
Then there is the content that can be accessed. Recently, before Starbucks took steps to block the accessing of pornography via its WiFi networks, the coffee shop chain received a lot of criticism from consumers who had caught glimpses of other customers accessing pornography on their devices.
Secure WiFi Access for Shops Brings Many Benefits
The provision of secure WiFi access for shops tells customers you are committed to ensuring they can access the Internet safely and securely on your premises. It tells parents that you are committed to protecting minors and ensuring they can access the Internet without being exposed to adult content. It tells consumers that you care, which helps to improves the image of your brand. It is also likely to result in positive online reviews.
Providing secure WiFi access for shops makes it easier for you to gain an insight into customer behavior. A web filtering solution will provide you with reports on the sites that your consumers are accessing. This allows you to profile your customers and find out more about their interests. You can see what sites they access, which can guide your future advertising programs and help you develop more effective marketing campaigns. You can also find out more about your real competitors from customers browsing habits.
The provision of secure WiFi access for shops will also help you to reduce legal liability. If you do not block illegal activities on your WiFi network, such as file sharing (torrents) sites, you could face legal action for allowing the downloading of pirated material. The failure to block pornography could result in a lawsuit if a minor is not prevented from accessing adult content.
WebTitan – Secure WiFi Access for Shops Made Simple
Secure WiFi access for shops doesn’t have to be complicated or expensive. TitanHQ offers a solution that is cost effective, easy to implement, requires no technical skill, has no effect on Internet speed and the solution can protect any number of shops in any number of locations.

Hospitals often invest heavily in solutions to secure the network perimeter, although the importance of Internet and WiFi filtering in hospitals is often misunderstood. Network and software firewalls are essential, but alone they will not provide protection against all attacks. As healthcare IT security staff know all too well, the actions of employees can see cybersecurity defenses bypassed.
A look at the Department of Health and Human Services’ Office for Rights breach portal shows just how many cyberattacks on hospitals are now occurring. Cybercriminals are targeting healthcare organizations due to the value of protected health information (PHI) on the black market. PHI is worth ten times as much as credit card information, so it is no surprise that hospitals are in cybercriminals’ crosshairs. Even a small hospital can hold the PHI of more than 100,000 individuals. If access is gained to a hospital network, the potential rewards for a hacker are considerable.
There has also been a massive increase in ransomware attacks. Since hospitals need access to patients’ PHI, they are more likely to pay a ransom to regain access to their data than in other industry sectors. Hollywood Presbyterian Medical Center paid $17,000 for the keys to unlock its files following a ransomware attack in in February 2016. It was one of several hospitals to give in to attackers’ demands following ransomware attacks.
A Web Filter is an Important Extra Security Layer to Protect Against Phishing Attacks
Phishing is one of the main threats for healthcare organizations, so it is vital for the email system to be secured with an advanced spam filtering solution and for security awareness training to be provided to employees. However, layered defenses are required to reduce the threat of phishing to a reasonable and acceptable level.
A web filtering solution is an important additional control in the fight against phishing. If an employee clicks on a hyperlink in a phishing email that has made it past email security defenses, the phishing website can be blocked. Instead, the user will be directed to a block screen and a potential account compromise can be avoided. A web filter will also help to protect users from malicious redirects when browsing the internet.
The Hospital WiFi Environment is a Potential Gold Mine for Cybercriminals
Another common weak point is the WiFi network. IT security teams may have endpoint protection systems installed, but often not on mobile devices that connect to WiFi networks. The increasing number of wireless devices that are now in use in hospitals increases the incentive for cybercriminals to attempt to gain access to WiFi networks. Not only do physicians use mobile phones to connect to the networks and communicate PHI, there are laptops, tablets and an increasing number of medical devices connected to WiFi networks. As the use of mobile and IoT devices in healthcare continues to grow, the risk of attacks on the WiFi environment will increase.
Patients also connect to hospital WiFi networks, as do visitors to hospitals. They too need to be protected from malware and ransomware when connected to hospital guest WiFi networks. One of the easiest ways to protect the devices that connect to WiFi networks is a web filtering solution. A web filter allows IT teams to carefully control the types of content that can be accessed on hospital WiFi networks, block malware downloads, and prevent all users from visiting malicious websites. Internet and WiFi filtering in hospitals should be included in cybersecurity defenses to reduce the risk of malware downloads from the internet and is an important additional control against insider breaches.
Internet and WiFi filtering in Hospitals is Not Just About Blocking Cyberthreats
Malware, ransomware, hacking, and phishing prevention aside, there are other important reasons for implementing Internet and WiFi filtering in hospitals.
Guest WiFi access in hospitals is provided to allow patients and visitors to access to the Internet; however, there is only a certain amount of bandwidth available. If Internet access is to be provided, all patients and visitors should be able to gain access. Internet and WiFi filtering in hospitals can be used to restrict access to Internet services that consume large amounts of bandwidth, especially at times when network usage is heavy. Time-based controls can be applied at busy times to block access to video streaming sites, for example, to ensure all users can enjoy reasonable Internet speeds.
It is also important to prevent patients, visitors and healthcare professionals from accessing inappropriate website content. Internet and WiFi filtering in hospitals should include a block on adult content and other inappropriate or illegal material. Blocks can easily be placed on illegal file sharing websites, gambling or gaming sites, or any other undesirable category of web content.
Internet and WiFi filtering in hospitals ensures WiFi networks can be used safely and securely by all users, including minors. Blocking illegal, undesirable, and age-inappropriate content is not just about protecting patients and visitors. It also reduces legal liability.

Hotel guests used to choose hotels based on whether free WiFi was available, now free WiFi is no longer enough – secure WiFi for hotels is required to ensure the Internet can be accessed safely, a fast connection is essential and the WiFi signal must be reliable.
Even budget hotels know the attractive power of free WiFi and how much easier it is to attract guests with free, reliable Internet access. Forrester Research conducted a survey back in 2013 that showed 90% of hotel guests considered free WiFi access to be the most important hotel amenity, while 34% of respondents said when it comes to choosing a hotel, free WiFi was a deal breaker when choosing a place to stay.
Providing Free WiFi is No Longer Enough
Now that most hotels are offering free WiFi, travelers have become much more discerning. Free WiFi access is no longer sufficient. Hotel guests want reliable access, good Internet speeds, sufficient bandwidth to stream music and videos and secure WiFi for hotels is similarly important. Hotels now need to improve their WiFi networks to continue to attract business.
A quick look on TripAdvisor and other review sites is all it takes to assess the quality of the Internet connection. There are even websites dedicated to providing this information. A poor WiFi signal is one of the most common complaints about hotels.
Providing an excellent Internet connection may not mean a 5-star review is guaranteed – but one or two-star reviews can be expected if the Internet connection or WiFi coverage is poor.
If you really want to attract more guests, provide free WiFi access. If you want to gain a serious competitive advantage, ensure all rooms have an excellent signal, there is sufficient bandwidth and make sure your network is secure. Guests now expect the same protections they have at home.
Common Problems with Hotel WiFi Networks
Listed below are some of the common problems reported by guests about hotel WiFi
Problems connecting more than one device to the network – Hotels often have WiFi networks with limited bandwidth. Restrictions may be in place that only allow one device to be connected per room. For a couple or family, that is no longer sufficient. Most guests will require at least two devices to be connected simultaneously per room, without Internet speed dropping to a snail’s pace.
Parents do not want their children to be able to access porn – A night in a hotel should be a relaxing experience. Parents do not want to have to spend their time policing the Internet. They want controls in place to make sure adult content cannot be accessed by their kids.
Connecting to guest WiFi should be safe and secure – Guests should be protected from malware and ransomware infections and steps should be taken by the hotel operator to reduce the risk of man-in-the-middle attacks. Safe and secure WiFi for hotels is essential. Accessing hotel WiFi should not result in nasties being transferred to guests’ devices. Safe and secure WiFi for hotels is especially important for business travelers. They should be able to enter their usernames and passwords without risking an account compromise.
Bandwidth issues are a major bugbear – If some guests are streaming video to their devices, it should not prevent other users from accessing the Internet or enjoying reasonable Internet speeds. Even at busy times, all guests should be able to connect.
How to Resolve these Problems?
Bandwidth is a major issue. Increasing bandwidth comes at a cost. If free WiFi is provided, it is difficult to recover that expenditure. There are solutions however. Hotels can offer free WiFi access to all guests, yet block streaming sites and other bandwidth-heavy activities. If guests want to be able to stream video, they could be offered a premium service and be charged for non-standard access. The same could apply to adult content. Hotels could offer family-friendly WiFi as standard, with a paid for service having fewer restrictions.
Secure WiFi for hotels is a must. Hotels can implement solutions that block malware and prevent guests from accessing phishing websites. Providing an encrypted connection is also essential. Guests should be able to login to their accounts without being spied on.
Secure WiFi for Hotels Made Simple
A web content filter can be used to resolve the above problems and ensure safe and secure Internet access for all guests. Arranging secure WiFi for hotels is simple with TitanHQ.
TitanHQ’s WebTitan Cloud for WiFi is a content filter with a difference. The solution can be deployed on existing hardware with no need for any software installations.
