Far too often, news of data breaches is accompanied by details of the failures in network security that allowed a hacker access to confidential data. Many of these failure are avoidable with adequate precautions such as a spam email filter and mechanism for controlling access to the Internet.
Almost as many breaches in network security can be attributed to poor employee training. Password sharing, unauthorized downloads and poor online security practices can result in hackers gaining easy access to a network and extracting confidential data at will.
It has been well chronicled that hackers will bypass organizations with strong network security and turn their attention to fish that are easier to catch. Make sure your organization does not get caught in the net – implement appropriate web filters and educate your employees on the importance of network security.
It is straightforward to implement security controls to protect wired networks, but many businesses fail to apply the same controls to improve WiFi security, often due to a lack of understanding about how to improve wireless access point security. In this post we cover some of the main threats associated with WiFi networks and explain how easy it can be to improve wireless access point security.
Wireless Access Points are a Security Risk
Most businesses now apply web filters to control the types of content that can be accessed by employees on their wired networks but securing wireless networks can be more of a challenge. It is harder to control and monitor access and block content on WiFi networks.
Anyone within range of the access point can launch an attack, especially on public WiFi hotspots which have one set of credentials for all guest users. It is therefore essential that controls are implemented to improve wireless access point security and protect users of the WiFi network.
WiFi Security Threats
A single set of credentials means cybercriminals are afforded a high degree of anonymity. That allows them to use WiFi networks to identify local network vulnerabilities virtually undetected. They could conduct brute force attacks on routers, for example, or use WiFi access to inject malware on servers that lack appropriate security. If access is gained to the router, attacks can be launched on connected devices, and malware can be installed on multiple end points or even POS systems to steal customers’ credit/debit card information.
The cyberattack on Dyn is a good example of how malware can be installed and used for malicious purposes. The DNS service provider was attacked which resulted in large sections of the Internet being made inaccessible. A botnet of more than 100,000 compromised routers and IoT devices was used in the attack.
Man-in-the-Middle attacks are also common on Wi-Fi networks. Any unencrypted content can be intercepted, such as if information is exchanged between a user and a HTTP site, rather than HTTPS, if a VPN is not used.
Public WiFi networks are often used for all manner of nefarious purposes due to the anonymity provided. If users take advantage of that anonymity to access illegal content and download child pornography or perform copyright infringing downloads of music, films, and TV shows from P2P file sharing sites, an investigation would center on the hotspot provider. Questions would likely be asked about the lack of security controls to prevent illegal website access.
The Easy Way to Improve Wireless Access Point Security
The easy way to improve wireless access point security is a web filtering solution. Web filtering solutions are usually implemented by businesses to secure wired networks, but solutions also exist to improve wireless access point security.
A web filter forms a barrier between the users of the network and the Internet. Controls can be applied to stop users from accessing dangerous, illegal, or inappropriate website content. Even if each user has their own access controls, without a web filter, users will still be vulnerable to malware attacks and phishing attempts and the hotspot provider may be liable for illegal activities over the WiFi network.
There are two ways of implementing WiFi web filtering to improve wireless access point security. One is to rely on a list of categorized domain names and use that to control content. The other is DNS-layer web filtering, which uses the DNS lookup process that is required before any user is directed to a website after entering the domain name into their browser. The DNS server turns the domain name into an IP address to allow the web page to be found.
Why DNS Filtering is Best Way to Improve Wireless Access Point Security
The main difference between the two types of web filtering is the point at which access is blocked. With a traditional web filter, content is first downloaded before it is blocked, which is a risk. With DNS-layer filtering, content is blocked during the lookup process before content is downloaded.
If content is downloaded before being blocked, this will naturally have an impact on available bandwidth. DNS-layer filtering has no impact on bandwidth, since the content is blocked before it is downloaded.
DNS filtering does not need to be integrated with other systems and it works across all devices and operating systems, since they all use DNS servers to access websites.
DNS filtering is also quick and easy to implement. No appliances need to be purchased, hardware doesn’t need to be upgraded, and no software downloads are required. A simple change to the DNS is all that is required to point it to the provider’s DNS server. It is also much easier to maintain. No software updates are necessary and, in contrast to other security solutions, no patching is required. It is all handled by the service provider.

In this post we explore the use of Internet filtering to improve employee productivity, including statistics from recent surveys that show how many companies are now choosing to control employee Internet access more carefully.
Employee Productivity Falls on Black Friday and Cyber Monday
The staffing firm Robert Half Technology recently conducted a survey on 2,500 chief information officers (CIOs) across 25 metropolitan areas in the United States and more than 1,000 U.S. officer workers over 18 years of age to determine how Black Friday and Cyber Monday affect employee productivity.
The results of the survey provide an indication on what goes on throughout the year, but Black Friday and Cyber Monday were studied as they are the two busiest days for online shopping. The survey results show that three quarters of employees spent at least some of Cyber Monday shopping online on a work device. Four out of 10 workers said they spent more than an hour looking for bargains online on Cyber Monday while they were at work. 23% said they were expecting to spend even longer than that this year.
46% of workers said they would be online shopping on their work computers during their lunch hour and breaks, but 29% said they would be shopping throughout the day and would be keeping browser tabs open. 20% of workers said they would do online shopping at work in the morning.
While policies on accessing pornography may have been made crystal clear, online shopping is something of a gray area. 31% of employees were not aware of their company’s stance on online shopping on work devices. 43% said their employers permit it and 26% said it is not permitted.
The survey of CIOs shows 49% of companies allow online shopping within reason but that they monitor employee Internet use. 22% said they allow totally unrestricted Internet access while 29% have implemented solutions to block access to online shopping sites.
In June 2018, Spiceworks published the results of a survey that showed 58% of organizations actively monitor employee Internet activity and 89% of organizations use Internet filters to block at least one category of Internet content.
Most surveyed companies use Internet filtering to improve employee productivity. While only 13% block online shopping sites, many companies block other productivity-draining sites such as social media, gaming, gambling and dating sites.
Internet filtering to improve employee productivity is important, but the majority of companies are flexible when it comes to employee Internet use for personal shopping, provided employees keep it to a reasonable level.
Monitoring Employee Internet Access to Prevent Abuse
Many businesses use Internet filtering to improve employee productivity and enforce acceptable usage policies. Some control Internet access with an iron fist, others are much more permissive.
Regardless of the controls that are put in place, Internet filters also allow employers to keep close tabs on their employees’ Internet activity. An internet filter is a useful tool for monitoring employees, not just enforcing company policies.
Internet filters allow employers to easily check employee Internet use while maintaining a relatively permissive controls. This allows them to take action when individuals are abusing Internet access. Monitoring is easy as reports can be generated on user, group, or organization-wide activity while providing information on browsing activity in real time. Reports can also be automatically generated and sent to department heads or IT security teams.
Different controls can be applied to different user groups and time-based controls can be set, for instance, only permitting online shopping during lunch hours or other scheduled breaks. Such controls would be useful for stopping the 20% of workers that do their online shopping at work in the morning which, in many businesses, is the most important part of the day when productivity needs to be high.
Since controls can be applied for different types of Internet content, security can be maintained by blocking access to high risk sites and illegal or totally unacceptable content all of the time, while restrictions on other categories of content can be eased during relatively quiet periods.
In short, Internet filters should not be viewed just as a way of restricting employee Internet access, but as a tool for the management of Internet use to improve security and enjoy productivity gains while giving employees some flexibility.

There are many reasons why businesses should implement a WiFi filtering solution, but one of the most important aspects of WiFi filtering is protecting your brand.
The Importance of Brand Protection
It takes a lot of hard work to create a strong brand that customers trust, but trust can easily be lost if a company’s reputation is damaged. If that happens, rebuilding the reputation of your company can be a major challenge.
Brand reputation can be damaged in many ways and it is even easier now thanks to the Internet and the popularity of social media sites. Bad feedback about a company can spread like wildfire and negative reviews are wont to go viral.
Smart business owners are proactive and take steps to protect their digital image. They are quick to detect and enforce online copyright infringements and other forms of brand abuse. They monitor social media websites and online forums to discover what people are saying about their company and how customers feel about their products and services. They also actively manage their online reputation and take steps to reinforce their brand image at every opportunity.
Cyberattacks Can Seriously Damage a Company’s Reputation
One aspect of brand protection that should not be underestimated is cybersecurity. There are few things that can have such a devastating impact on the reputation of a company as a cyberattack and data breach. A company that fails to secure its POS systems, websites, and network and experiences a breach that results in the theft of sensitive customer data can see their reputation seriously tarnished. When that happens, customers can be driven to competitors.
How likely are customers to abandon a previously trusted brand following a data breach? A lot more than you may think! In late 2017, the specialist insurance services provider Beazley conducted a survey to find out more about the impact of a data breach on customer behavior. The survey was conducted on 10,000 consumers and 70% said that if a company experienced a data breach that exposed their sensitive information they would no longer do business with the brand.
WiFi Filtering and Protecting Your Brand
The use of Wi-Fi filtering for protecting your brand may not be the first thing that comes to mind when you think about brand protection, but it should be part of your brand protection strategy if you offer WiFi access to your customers or provide your employees with wireless Internet access.
It is essential for businesses to take steps to ensure their customers are protected and are not exposed to malware or phishing websites. If a customer experiences a malware infection or phishing attack on your WiFi network the fallout could be considerable. If your employees download malware, they could give hackers access to your network, POS system, and sensitive customer data. If you offer free Wi-Fi to your customers, you need to make sure your Wi-Fi network is secured and that you protect your customers from malicious website content.
One of the most important aspects of WiFi filtering for protecting your brand is preventing your WiFi access points from being used for illegal activities. Internet Service Providers can shut down Internet access over illegal activities that take place over the Internet. That will not only mean loss of WiFi for customers but could see Internet access lost for the whole company. Your company could also face legal action and fines.
If WiFi users can access pornography and other unacceptable content, a brand can be seriously tarnished. Imagine a parent discovers their child has seen pornography via your WiFi network – The failure to prevent such actions could be extremely damaging. WiFi filters allow businesses to carefully control the content that can be accessed on their network and prevents customers from viewing harmful web content.

DNS web filtering for MSPs is an easy way to improve security for your clients, save them money, and boost your profits. This post explains the benefits of a DNS-level web filter for MSPs and their clients.
DNS web filtering is a great way for MSPs to boost profits, save clients money, and better protect them from cyber threats. Web filtering is an essential cybersecurity measure that businesses of all sizes should be using as part of their arsenal against malware, ransomware, botnets and phishing attacks. However, many MSPs fail to include web filtering in their security offerings and consequently miss out on an important income stream: One that requires little effort and generates regular monthly income.
What Are the Benefits of Web Filtering?
There are two main benefits of web filtering: Enforcing Internet usage policies and cybersecurity. Employees need to be able to access the Internet for work purposes, but many employees spend a considerable percentage of their working day accessing websites that have no work purpose. Cyberslacking costs businesses dearly. Businesses that do not filter the Internet will be paying their employees to check personal mail, view YouTube videos, visit dating websites, and more. A web filter will help to curb these non-productive activities and will also prevent employees from accessing inappropriate or illegal web content and avoid legal and compliance issues.
A recent study by Spiceworks revealed the extent of the problem. 28% of employees at large companies (more than 1,000 employees) spend more than four hours a week on personal Internet use and the percentages increase to 45% for mid-sized businesses and 51% for small businesses. The difference in those figures reflects the fact that more large businesses have implemented web filters. 89% of large companies have implemented a web filter to curb or prevent personal Internet usage and, as a result, benefit from an increase in productivity of the workforce.
Web filtering is essential in terms of cybersecurity. The Spiceworks study revealed 90% of large companies use a web filter to block malware and ransomware infections. A web filter prevents employees from accessing websites known to be used for phishing and those that host malware.
The Spiceworks study showed just how important a web filter is in this regard. 38% of companies had experienced at least one security incident in the past year as a result of employees visiting web pages for personal use, most commonly webmail services and social media channels.
Additional benefits of web filtering include improving network performance and ensuring sufficient bandwidth is available for all users – by blocking access to bandwidth-heavy online activities such as gaming and video streaming.
From the productivity gains alone, a web filter will pay for itself. Add in the costs that are saved by preventing malware and phishing attacks and use of a web filter really is a no brainer.
Why DNS Web Filtering for MSPs is the Way Forward
MSPs have three main web filtering options open to them. An appliance-based web filter, a virtual appliance or software solution, or a DNS filter. DNS web filtering for MSPs is usually the best choice.
DNS web filtering for MSPs avoids the need for hardware purchases so there is not an initial high cost for clients or for the MSP, since a powerful appliance does not need to be installed in an MSP’s own data center. DNS web filtering for MSPs means no site visits are necessary to install the solution as no hardware is required and no software downloads are necessary. DNS web filtering is not restricted by operating systems and is hardware independent, and since there are no clients to install, there will not be any installation issues. A DNS web filter also doesn’t have any impact on Internet speed.
A SaaS DNS web filtering solution, such as WebTitan Cloud, allows MSPs to deploy the web filter for their clients in a few minutes. All that is required is to direct clients’ DNS the cloud-based filter.
DNS web filtering for MSPs is easy to implement, simple to use, requires little management, and with WebTitan Cloud, MSPs benefit from generous margins. Improving clients’ security posture and helping them make important productivity gains could not be easier.
Why WebTitan Cloud is the Best Choice for MSPs
WebTitan Cloud has been developed to meet the needs of the SMB marketplace but with MSPs firmly in mind. WebTitan includes a full suite of pre-configured reports (with scope for customization) to allow MSPs to show their clients the sites that have been blocked and what employees have been up to online. The reports give MSP clients total visibility into their web traffic and highlight problem areas and show trends affecting network performance. The reports can be automated and sent directly to clients with no MSP involvement.
Some of the key benefits of TitanHQ’s DNS web filtering for MSPs are detailed below:
WebTitan Cloud can be hosted by TitanHQ or by MSPs in a private cloud
WebTitan Cloud includes APIs to integrate with auto-provisioning, billing, and monitoring systems
MSPs do not need to become an ISP to use the service
WebTitan Cloud is scalable to hundreds of thousands of users
WebTitan Cloud includes multiple management roles
New customers can be added and configured in minutes
WebTitan Cloud can be supplied in white-label form ready for an MSP’s logos and UI color schemes

The biggest cyber threat to SMBs is ransomware, according to Dato’s State of the Channel Report. While other forms of malware pose a serious risk and the threat from phishing is ever present, ransomware was considered to be the biggest cyber threat to SMBs by the 2,400 managed service providers that were polled for the study.
Many SMB owners underestimate the cost of mitigating a ransomware attack and think the cost of cybersecurity solutions to prevent attacks, while relatively low, are not justified. After all, according to Datto, the average ransom demand is just $4,300 per attack.
However, the ransom payment is only a small part of the total cost of mitigating an attack. The final cost is likely to be ten times the cost of any ransom payment. Datto points out that the average total cost of an attack on an SMB is $46,800, although there have been many cases where the cost has been far in excess of that amount.
One of the most common mistakes made by SMBs is assuming that attacks will not occur and that hackers are likely to target larger businesses with deeper pockets. The reality is SMBs are being targeted by hackers, as attacks are easier to pull off. SMBs tend not to invest heavily in cybersecurity solutions as larger businesses.
Anti-Virus Software is Not Effective at Preventing Ransomware Attacks
Many SMB owners mistakenly believe they will be protected by anti-virus software. However, the survey revealed that 85% of MSPs said clients that experienced a ransomware attack had anti-virus solutions installed. Anti-virus software may be able to detect and block some ransomware variants, but since new forms of ransomware are constantly being developed, signature-based cybersecurity solutions alone will not offer a sufficient level of protection.
Many SMBs will be surprised to hear just how frequently SMBs are attacked with ransomware. More than 55% of surveyed MSPs said their clients had experienced a ransomware attack in the first six months of this year and 35% experienced multiple attacks on the same day.
Some cybersecurity firms have reported there has been a slowdown in ransomware attacks as cybercriminals are increasingly turning to cryptocurrency mining. While that may be true for some cybercriminal gangs, the ease of conducting attacks using ransomware-as-a-service means many small players have started attacking SMBs. That is unlikely to change.
92% of surveyed MSPs said they thought ransomware attacks would continue at current levels or even increase throughout this year and next.
Ransomware attacks are even being conducted on Apple operating systems. In the past year, there has been a five-fold increase in the number of MSPs who have reported ransomware attacks on macOS and iOS operating systems.
“Not only have ransomware attacks increased in recent years, but the problem may even be bigger than we know, as many attacks go unreported,” explained Jeff Howard, Founder and Owner, of the Texas MSP Networking Results. Datto suggests that only one in four attacks are reported to law enforcement.
How to Protect Against SMB Ransomware Attacks
To protect against ransomware attacks, businesses need to implement a range of solutions to block the most common attack vectors. To block email-based attacks, advanced spam filtering technology is required, and end user security awareness training is essential. To block ransomware downloads from malicious websites, web filtering software should be implemented.
Business continuity and disaster recovery technology should be implemented to ensure that a quick recovery is possible in the event of an attack, and naturally intelligent backing up is required to ensure files can be recovered without paying a ransom.
MSPs need to explain the risks to SMBs, along with the solutions that need to be installed to prevent attacks and the likely cost of recovery. Many businesses are shocked to discover the true cost of a ransomware attack.
How TitanHQ Can Help Improve Defenses Against SMB Ransomware Attacks
TitanHQ has developed two innovative cybersecurity solutions that work in tandem to block the two most common attack vectors: Email and Internet attacks. SpamTitan is a powerful spam filtering solution that combines two AV engines with intelligent scanning of incoming mail using a variety of techniques to identify malicious messages and new ransomware variants and block them at source.
WebTitan is a powerful web filtering solution that can block malvertising attacks, drive-by ransomware downloads, and prevent employees from visiting malicious websites. Both solutions should be part of an SMBs arsenal to protect against ransomware and malware attacks and both solutions should be part of an MSPs security stack.

Most businesses are aware of the importance of securing their Wi-Fi networks; however, in some industry sectors Wi-Fi security has not been given the importance it requires. Wi-Fi security for hotels, for instance, is often lacking, even though the hospitality sector is being actively being targeted by cybercriminals who see hotel Wi-Fi as a rich picking ground.
Hotel Chains are Under Attack
Hotels are an attractive target for cybercriminals. They satisfy the two most important criteria for cybercriminals when selecting targets. Valuable data that can be quickly turned into profit and relatively poor cybersecurity which makes conducting attacks more straightforward.
In 2018, there have been several major cyberattacks on hotel groups. In November 2018, Federal Group, which runs luxury hotels in Tasmania, experienced an email security incident that exposed the personal data of some of its members. A cyberattack on the Radisson Hotel Group was also reported. In that case it resulted in the exposure of the personal information of its loyalty program members.
In August one of China’s largest chains of hotels – Huazhu Hotels Group Ltd – which operates 13 hotel brands – suffered a cyberattack that affected an estimated 130 million people. In June one of Japan’s largest hotel groups, Prince Hotels & Resorts, experienced a cyberattack that impacted almost 125,000 customers. In 2017 there were major data breaches at Hilton, Hyatt Hotels Corporation, Trump Hotels, Four Seasons Hotels, Loews Hotels, Sabre Hospitality Solutions, and InterContinental Hotels Group to name but a few.
The Cost of a Hotel Data Breach
When a data breach occurs the costs quickly mount. Access to data and networks must be blocked rapidly, the breach must be investigated, the cause must be found, and security must be improved to address the vulnerabilities that were exploited. That invariably requires consultants, forensic investigators and other third-party contractors. Affected individuals must be notified and credit monitoring and identity theft protection services may need to be offered.
The direct costs of a hotel data breach are considerable. The Ponemon Institute calculated the average cost of a data breach in 2018 had risen to $3.86 million. That was for a breach of up to 100,000 records. Larger breaches cost considerably more.
Then there is GDPR. Fines of up to €20 million or 4% of global annual turnover (whichever is higher) can be issued for GDPR compliance failures, which includes data breaches that resulted from poor security.
What is much harder to calculate is the cost of reputation damage and the customer churn rate after a breach. Damage to a hotel chain’s reputation can be long lasting and in the highly competitive hospitality industry, it could even be disastrous.
The security firm Ping Identity recently published the results from its 2018 Consumer Survey: Attitudes and Behavior in a Post-Breach Era. 3,000 people from the USA, UK, France, and Germany were surveyed for the study, which investigated the expectations of customers and the fallout from data breaches. 78% of respondents said they would stop engaging with a brand online after a breach and 36% would stop engaging with a brand altogether. Could your hotel group weather a 78% drop in online bookings or a loss of more than a third of your customer base?
Wi-Fi Security for Hotels
Cybersecurity solutions should be implemented to protect hotel networks from cyberattacks and prevent customer’s personal information from being accessed by cybercriminals. Perimeter cybersecurity solutions such as firewalls are essential, but Wi-Fi security for hotels should not be underestimated.
Guests use the Wi-Fi network to conduct business while at the hotel, for entertainment, and communication. Guests typically bring three devices that they connect to hotel Wi-Fi networks. A hotel with 100 guests potentially means 300 devices connecting to Wi-Fi. There is a high probability that at least some of those devices will be infected with malware, which could be transferred to other guests.
Hotel guests often access types of content that they do not access at home – sites that carry a higher risk of resulting in a malware download. Hackers often exploit poor hotel Wi-Fi security to attack guests. The DarkHotel threat group is a classic example. The group targets high profile hotel guests and has been doing so for more than a decade. If Wi-Fi security for hotels is substandard, successful attacks are inevitable.
Naturally guest and business Wi-Fi networks should be separated to ensure that one does not pose a threat to the other. A VLAN should be set up for the wired network, with a separate VLAN for internal wireless access points and those used by guests.
Wi-Fi security should include WPA2 encryption to prevent the interception of data and a web filtering solution should be implemented to protect guests from phishing websites and sites hosting malware. A web filter will also allow hotels to control the types of content that can be accessed by guests and restrictions can be put in place to create family-friendly Wi-Fi access and prevent guests from accessing illegal web content.

This year has seen several ransomware attacks on cities and municipal targets, clearly demonstrating that the threat from ransomware has not abated, despite several analyses from cybersecurity firms that suggest hackers are moving away from ransomware and concentrating on cryptomining malware attacks.
Cryptocurrency miners have certainly become more popular and their use has increased substantially in recent months, but there is still a significant threat from ransomware.
Ransomware development may have slowed, but ransomware attacks on cities and other high value targets have not. In fact, October has seen two new ransomware attacks on cities in the United States, along with several attacks on municipal targets. In the past few months. It is clear that the threat is not going away any time soon.
$2,000 Ransom Paid to Resolve City of West Haven Ransomware Attack
The city of West Haven ransomware attack started on the morning of October 16, 2018, and by the time the attack had been contained, 23 servers had been encrypted and taken out of action. Prompt action limited the scope of the attack, although it did cause major disruption as computers on the affected network had to all be shut down.
The attack affected a critical system, and after an assessment of the situation, the decision was taken to pay the ransom. Considering the number of servers affected, the ransom demand was relatively low. The city paid $2,000 in Bitcoin for the keys to decrypt its files.
Art House, Connecticut’s chief of cybersecurity, explained that this was one of several targeted ransomware attacks on cities and municipal services in the state in recent weeks. In February, around 160 computers were affected by ransomware in more than a dozen agencies in the state according to the Department of Administrative Services, and a month later the state’s Judicial Branch was attacked and had more than 100 servers encrypted.
City of Muscatine Ransomware Attack
The West Haven ransomware attack was shortly followed by a ransomware attack on the city of Muscatine in Ohio, which saw files on several government servers encrypted. The attack is understood to have started on October 17 and caused considerable disruption especially to services at City Hall.
Few details about the attack have been made public, although it is understood that the ransom demand was not paid. Instead, IT teams have had to painstakingly rebuild affected servers and workstations and restore files from backups.
Ransomware Attack on City of Atlanta
In August one of the most serious ransomware attacks on cities occurred. The City of Atlanta was attacked with SamSam ransomware, which was manually deployed on multiple computers after access had been gained to the network. The attack occurred in March and took down computers used for many city services, causing major disruption for weeks. A ransom demand of around $50,000 was issued, although the decision was taken not to pay. Initially the cost of recovery was expected to reach $6 million. Later estimates in the summer suggest that the final cost may exceed $17 million, highlighting just how costly ransomware attacks on cities can be.
Ransomware Attacks on Municipal Services Becoming More Common
Ransomware attacks on cities are becoming more common, as are attacks on municipal targets. In October, the Onslow Water and Sewer Authority in Jacksonville, North Carolina was attacked with ransomware resulting in most systems being taken out of action. In that case, a dual attack occurred, which started with the Emotet Trojan followed by the deployment of Ryuk ransomware two weeks later. The attack is expected to disrupt services for several weeks. The Indiana National Guard also suffered a ransomware attack in October. In both cases, the ransom was not paid.
Prevention and Incident Response
One of the reasons behind the rise in ransomware attacks on cities is underinvestment in cybersecurity defenses. Too little has been spent on protecting systems and updating aging hardware and software. With many vulnerabilities left unaddressed, staff receiving insufficient training, and even basic cybersecurity defenses often found lacking, it is no surprise that the attacks are increasing.
The only way that the attacks will be stopped is by spending more on cybersecurity defenses and training to make it much harder for attacks to occur. It can certainly be hard to find the money to commit to cybersecurity, but as the City of Atlanta found out, the cost of prevention is far lower than the cost of recovery from a ransomware attack.
Many businesses want to block websites at work and exercise greater control over employee Internet access. Acceptable Internet usage policies can be developed and employees told what content they are allowed to access at work, but there are always some employees that will ignore the rules.
In some cases, policy violations may warrant instant dismissal or other disciplinary action, but that takes HR staff away from other important duties. If staff are fired, replacements must be found, trained, and brought up to speed, and the productivity losses that result can be considerable.
The Dangers of Unfettered Internet Access
Before explaining how to block websites at work, it is worthwhile explaining the problems that can arise from the failure to exert control over the content that can be accessed through wired and wireless networks.
While extreme cases of internet abuse need to be tackled through HR, low level Internet abuse can also be a problem. Any time an employee accesses a website for personal reasons, it is time that is not being spent on work duties. Checking emails or quickly visiting a social media website is unlikely to have a major impact on productivity, but when cyber-slacking increases its effect can certainly be felt. If all employees spend 30 minutes a day on personal Internet use, the productivity losses can be considerable – A business with 100 workers would lose 50 hours of working time a day, or 1,100 hours a month!
In addition to lost opportunities, Internet use carries a risk. Casual surfing of the Internet by employees increases the probability of users encountering malware. The accessing of personal webmail at work could easily result in a malware infection on a work device, as personal mail accounts are not protected by the filtering controls of an organization’s email gateway. If illegal activities are taking place at work, the legal ramifications can be considerable. It will be the business that will be liable in many cases, rather than the individual employee.
The easiest solution is for businesses to enforce their acceptable internet usage policies and simply block websites at work that are not required for normal working duties. Preventing end users from visiting certain categories of web content – social media websites, gaming and gambling websites, dating sites, adult content, and other NSFW web content – is the easiest solution.
Even legitimate use of the Internet for work purposes carries risks. There has been a major increase in phishing attacks on businesses in recent years and mitigating attacks can prove incredibly costly. Technical solutions that are used to block websites at work to prevent cyber-slacking can also be configured to block access to phishing websites and prevent malware downloads.
The Easy Way to Block Websites at Work
The easiest way to block websites at work is to use a web filtering solution. This could be a physical appliance through which all Internet traffic is routed, a virtual appliance installed on your existing hardware, or a cloud-based solution. The latter is a popular solution for SMBs as the cost of implementation is minimal and the web filter can be set up in a matter of minutes. All that is required is to make a simple change to point the DNS to the cloud web-filter and all traffic will be routed though the solution.
Not all businesses need to exercise the same controls over Internet content so granular controls are essential. With a cloud-based web filter such as WebTitan, it is easy to block websites at work. The administrator simply logs into the administration panel through a web browser and clicks on the checkboxes of content that they want the filter to block. Blocking adult entertainment, gambling, gaming, dating, and social media by category is common. WebTitan also allows controls to implemented by keyword, through the use of blacklists, or through keyword scoring.
It is not practical to apply the same settings across the board for all employees. The marketing department, for instance, will need access to social media networks when other employees may not. With WebTitan, filtering controls can easily be set at the organization level, by user group, or for individuals. Time-based filters can also be applied to allow controls to be eased outside of standard working hours, if required.

Windows Remote Desktop Protocol attacks are one of the most common ways cybercriminals gain access to business networks to install backdoors, gain access to sensitive data, and install ransomware and other forms of malware.
This attack method has been increasing in popularity over the past two years and there has also been a notable rise in darknet marketplaces selling exposed RDP services and RDP login credentials. The high number of Remote Desktop Protocol attacks has prompted the Federal Bureau of Investigation (FBI) Internet Crime Complaint Center (IC3) and the Department of Homeland Security to issue an alert to businesses in the United States to raise awareness of the threat.
Remote Desktop Protocol is a proprietary Windows network protocol that allows individuals to remotely access computers and servers over the Internet and gain full control of resources and data. RDP is often used for legitimate purposes, such as allowing managed security service providers (MSSPs) and managed service providers (MSPs) to remotely access devices to provide computer support without having to make a site visit. Through RDP, input such as mouse movements and keystrokes can be transmitted over the Internet with a graphical user interface sent back.
In order to gain access to a machine using RDP, a user must be authenticated by supplying a username and password. Once a user is authenticated, the resources on that device can be accessed. While authorized individuals can use RDP connections, so too can cybercriminals if they have access to login credentials or are able to guess usernames and passwords. As with any software, RDP can contain flaws. For instance, flaws in the CredSSP encryption mechanism could be exploited to perform man-in-the-middle attacks.
Cybercriminals are identifying vulnerable RDP sessions over the Internet and are exploiting them to gain access to sensitive information and conduct extortion attacks. The threat actors behind SamSam ransomware, which has been used in many attacks on U.S. businesses, educational institutions, and healthcare providers, often gain access to networks through brute force attempts to guess weak passwords. The threat actors behind CrySiS and CryptON ransomware attack businesses through open RDP ports and similarly use brute force and dictionary attacks to guess passwords.
How to Prevent Windows Remote Desktop Protocol Attacks
There are four main vulnerabilities that can be exploited to gain access to Windows devices that have RDP enabled:
Exploitation of weak passwords
Use of outdated versions of RDP
Failure to restrict access to the default RDP port – TCP 3389
Failure to block users after a set number of unsuccessful login attempts
Strong passwords should be used to make it harder for cybercriminals to use brute force tactics to guess login credentials. Dictionary words should be avoided. Default passwords must be changed and passwords should be at least 8 characters and include a mix of upper/lower case letters, numbers, and special characters. Rate limiting is also essential. A user should be blocked after a set number of failed login attempts have been made and, if possible, two-factor authentication controls should be implemented. External to internal RDP connections should be limited and software should be kept up to date.
An audit should be conducted to identify all systems that have RDP enabled, including cloud-based virtual machines with public IP addresses. If RDP is not required, it should be disabled. A list of systems with RDP enabled should be maintained and available patches should be applied promptly. All open RDP ports should be located behind a firewall and access should only be possible by using a VPN.
Logging mechanisms should be applied, and successful and unsuccessful login attempts should be regularly monitored to identify systems that have been attacked.
To ensure that recovery from a ransomware or sabotage attack is possible, all data must be regularly backed up and a good backup strategy adopted.
By regulating, monitoring, and controlling the use of RDP and addressing vulnerabilities, it is possible to reduce risk and prevent Remote Desktop Protocol attacks.
Recent research has shown that the United States is the main distributor of exploit kits and hosts the most malicious domains and cyberattacks on websites have increased sharply.
United States Hosts the Most Malicious Domains and Exploit Kits
The United States hosts the most malicious domains and is the number one source for exploit kits, according to new research conducted by Palo Alto Networks. Further, the number of malicious domains increased between Q1 and Q2 in the United States. In all countries, apart from the Netherlands, the number of malicious domains remained constant or declined.
Exploit activity is only at a fraction of the level of 2016, although the web-based kits still pose a major threat to businesses with poor patching processes and a lack of protections against web-based attacks.
Three exploit kits have been extensively used throughout Q1 and Q2, 2018: Sundown, Rig, and KaiXin. The United States is the number one source for the Sundown and Rig EKs and is number two behind China for the KaiXin exploit kit. Further, a new exploit kit was detected in Q2: Grandsoft. The United States is also the number one source for this new exploit kit.
More than twice the number of exploit kits are hosted in the United States than in Russia in second place. 495 malicious URLs were detected in the United States compared to 147 in Russia. 296 malicious URLs hosting exploit kits were detected in the United States, with Russia in second place with 139.
The Microsoft VBScript vulnerability, CVE-2018-8174, is being extensively exploited via these exploit kits. Microsoft released a patch in May 2018 to fix the flaw, but many companies have yet to install the update and are vulnerable to attack. Exploit kits are still using old vulnerabilities to install their malicious payloads. According to Palo Alto Networks’ Unit 42, two vulnerabilities are extensively used – The IE7 vulnerability – CVE-2009-0075 – and the Internet Explorer 5 vulnerability – CVE-2008-4844 – even though patches were released to fix the flaws more than 9 years ago.
The Jscript vulnerability in Internet Explorer 9 through 11 – CVE-2016-0189 – and the OleAut32.dll vulnerability – CVE-2014-6332 – have also been used in many attacks. One vulnerability known to be used in zero-day attacks was also detected.
Website Attacks on the Rise
Research conducted by SiteLock has revealed there has been a significant rise in attacks on websites in Q2, 2018. According to its study of more than 6 million websites, each website is attacked, on average, 58 times a day with one attack occurring every 25 minutes. That represents a 16% increase in website attacks since Q1, 2018.
Many search engines now alert users when websites have been discovered to contain malware, and Google sends warnings to site owners when malicious software is discovered. However, relatively few sites are being detected as malicious. SiteLock notes that out of 19.2 million sites that it has discovered to be hosting malicious files, only 3 million had been detected as malicious by the search engines.
The threat of exploit kit attacks and the rise in sites hosting malicious code highlights the need for businesses to deploy a web filtering solution to prevent employees from visiting these malicious sites and giving cybercriminals an opportunity to install malware on their networks.
Companies that take no action and fail to implement software solutions to restrict access to malicious sites face a high risk of their employees inadvertently installing malware. With the cost of a data breach now $3.86 million (Ponemon/IBM), the decision not to implement a web filter could prove incredibly costly.
Princess Locker ransomware has now morphed into Princess Evolution ransomware. The latest variant is one of several cryptoransomware threats that maximize the number of infections by using an affiliate distribution model – termed Ransomware-as-a-Service or RaaS.
RaaS sees affiliates given a percentage of the ransom payments they generate, while the author of the ransomware also takes a cut of the profits. Under this business model, the author can generate a much higher number of infections, which means more ransom payments. The affiliates get to conduct ransomware campaigns without having to develop their own ransomware and the author can concentrate on providing support and developing the ransomware further. For Princess Evolution ransomware, the split is 60/40 in favor of the affiliate. The RaaS is being promoted on underground web forums and prospective affiliates.
Ransomware attacks involving RaaS use a variety of methods to distribute the malicious payload as multiple actors conduct campaigns. Spam email is usually the main delivery mechanism for RaaS affiliates as it is easy to purchase large quantities of email addresses on darkweb sites to conduct campaigns. Brute force attacks are also commonly conducted.
Princess Evolution ransomware has also been loaded into the RIG exploit kit and is being distributed via web-based attacks. These web-based attacks take advantage of vulnerabilities in browsers and browser plug-ins. Exploits for these vulnerabilities are loaded into the kit which is installed on attacker-controlled web domains. Often legitimate sites are compromised have the exploit kit loaded without the knowledge of the site owner.
Traffic is generated to the websites through search engine poisoning, malvertising, and spam emails containing hyperlinks to the websites. If a user visits the website and has an exploitable vulnerability, the Princess Evolution ransomware will be silently downloaded.
At this stage, there is no free decryptor for Princess Evolution ransomware. If this ransomware variant is downloaded and succeeds in encrypting files, recovery is only possible by paying the ransom for the keys to unlock the encryption or rebuilding systems and recovering files from backups. The ransom demand is currently 0.12 Bitcoin – Approximately $750 per infected device.
Protecting against Princess Evolution ransomware attacks requires a combination of cybersecurity solutions, security awareness training, and robust backup policies. Multiple backups of files should be created, stored on at least two different media, with one copy stored securely off site. Infected devices may need to be re-imaged, so plans should exist to ensure the process can be completed as quickly as possible.
Cybersecurity solutions should focus on prevention and rapid detection of threats. A spam filtering solution – such as SpamTitan – will help to ensure that emailed copies of the ransomware or downloaders are not delivered to inboxes.
Care should be taken with any email sent from an unknown individual. If that email contains an attachment, it should not be opened, but if this is unavoidable, the attachment should be scanned with anti-virus software prior to opening. For greater protection, save the attachment to disk and upload it to VirusTotal for scanning using multiple AV engines.
A web filter such as WebTitan can block web-based attacks through general web browsing and by preventing end users from visiting malicious websites via hyperlinks in spam emails.
To reduce the risk of brute force attacks, strong, unique passwords should be used to secure all accounts and remote desktop protocol should be disabled if it is not required. If RDP is required, it should be configured to only allow connection through a VPN.
You should also ensure that all software, including browsers, browser extensions and plugins, and operating systems are kept patched and fully up to date.
Exploit kit activity may not be at the level it one was, but the threat has not gone away. Rig exploit kit activity has increased steadily in 2018 and now a new exploit kit has been detected.
The exploit kit has been named underminer by Trend Micro researchers, who detected it in July 2018. The Underminer exploit kit is being used to spread bootklits which deliver coinminer malware. The EK is primarily being used in attacks in Japan, although other East Asian countries have also seen attacks with activity now spreading beyond this region.
The underminer exploit kit was also detected by Malwarebytes researchers who note that the exploitation framework was first identified by the Chinese cybersecurity firm Qihoo360 in late 2017, when it was being used to deliver adware. Now the exploit kit is being used to deliver Hidden Bee (Hidden Mellifera) cryptocurrency mining malware. Trend Micro notes that evidence has been uncovered that strongly suggests the exploit kit was developed by the developers of Hidden Mellifera coinminer malware.
The exploit kit uses complex methods to deliver the payload with different methods used for different exploits. The developers have also incorporated several controls to hide malicious activity including the obfuscation of exploits and landing pages and the use of encryption to package exploits on-the-fly.
The EK profiles the user via a user-agent to determine if the user is of interest. If not, the user will be directed to a HTTP 404 error page. If a user is of interest, a browser cookie will be used to identify that user to ensure that the payload will only be delivered once, preventing reinfection and hampering efforts by researchers to reproduce an attack. URLs used in the attacks are also randomized to prevent detection by standard AV solutions. The coinminer is delivered via a bootkit which is downloaded through encrypted TCP tunnels.
The underminer exploit kit contains a limited number of exploits: The Adobe Flash Player exploit CVE-2018-4878, the use-after-free Adobe Flash Player vulnerability CVE-2015-5119, and the Internet Explorer memory corruption vulnerability CVE-2016-0189. Patches for all of the vulnerabilities were released in February 2018, July 2015, and May 2016 respectively.
The best defense against exploit kit attacks is prompt patching. All systems and applications should be kept 100% up to date, with virtual patching deployed on legacy systems and networks. Since there will always be a delay between the identification of a vulnerability and a patch being released, patching alone may not be sufficient to prevent all attacks, although EK developers tend to use old vulnerabilities rather than zero days.
In addition to prompt patching, cybersecurity solutions should be deployed to further reduce risk, such as a web filtering solution (WebTitan) to block users from visiting malicious websites and redirects through malvertising. In this case, one of the main ways that users are directed to the exploit kit is via adult-themed malvertising on legitimate adult websites. Using the web filter to block access to adult sites will reduce exposure.
Cybersecurity solutions should also be deployed to scan for malware installations and monitor for unusual activity and standard cybersecurity best practices should also be employed… the principle of least privilege and removing unused or unnecessary applications, plugins, and browser extensions.
The fact that a new exploit kit has been developed, and that it was recently updated with a new exploit, shows that the threat of web-based attacks has not gone away. EK activity may be at a fraction of the level of 2016, but businesses should not assume that attacks will not take place and should implement appropriate defenses to mitigate the threat.
A recent analysis of exploit kit activity by Trend Micro has shown that while exploit kit activity is at a fraction of what it was in 2016, the threat has not gone away. Links to malicious websites hosting exploit kits are still being distributed by spam email and malicious adverts are still being used to redirect web users to malicious websites hosting exploit kits.
Most of the exploit kits that were in use in 2016 have all but disappeared – Angler, Nuclear, and Neutrino. There was a rise in Sundown activity in 2017, but activity has now stopped, and Disdain and Terror exploit kits have similarly disappeared.
The demise of exploit kits as an attack vector has been attributed, in part, to the arrests of the operators of some of the most commonly used EKs such as Angler, although there have been fewer zero-day vulnerabilities to exploit. Many of the exploits used in exploit kits are for Flash vulnerabilities, and while use of Flash is declining, the creators of exploit kits are still attempting to exploit a handful of these Adobe Flash vulnerabilities. Many threat actors have switched to easier and less time-consuming ways of attacking businesses, but not all.
While most exploit kits are operating at a low level, the Rig exploit kit is still in use and has recently been updated once again. Further, there has been a steady increase in Rig exploit kit activity since April. Rig is most commonly used in attacks in Japan, which account for 77% of Rig activity.
The GrandSoft exploit kit is still active, although at a much lower level than Rig. This exploit kit was first seen in 2012 although activity all but disappeared until the fall of last year when it became active once again. Japan is also the country most targeted by the GrandSoft exploit kit (55% of activity), while the private exploit kit Magnitude is almost exclusively used in South Korea, which accounts for 99.5% of its activity.
For the most part, exploit kits are being used to exploit vulnerabilities that should have been patched long ago, such as the use-after-free vulnerability in Microsoft Windows’ VBScript engine (CVE-2018-8174) which was identified in April 2017 and patched in May 2017.
Internet Explorer vulnerabilities are also being exploited on vulnerable systems, with at least two exploits for IE flaws included in GrandSoft recently. Research conducted by Palo Alto networks showed that out of 1,583 URLs found in malicious emails, the majority were linked to exploit kits including Rig, Sundown, Sinowal, and KaiXin, with the latter still evolving with new exploits still being added – CVE-2016-0189 and CVE-2014-6322 – both IE VBScript flaws – the most commonly used.
Trend Micro has warned that the recent increase in zero-days – there were 119 last year – could see at least some exploits for these vulnerabilities introduced into exploit kits. MalwareBytes reported last month that a zero-day flaw in Flash Player’s ActionScript language had been incorporated into one exploit kit and was being actively used in attacks.
The fact that exploit kits are still being used strongly suggests that they are still working, which means that many systems are not being patched.
The threat from exploit kits does not appear to be going away, so it is still essential for businesses to ensure they are protecting against attacks.
Strict patch management practices are still important, as is the use of a web filter. Drive-by downloads still occur – unintentional downloads of malware by users in the belief that the files are genuine. Implementing a web filter can help to block these malware downloads, either by blocking specific file types or preventing end users from visiting known malicious websites. Web filters can also be used to block adware, which continues to plague businesses.
Why should businesses use a web filtering solution? Listed below are three key benefits of web filtering for businesses.
Protection Against Exploit Kits
Email spam is the most common attack vector used to deliver malware, and while the threat from exploit kits is nowhere near the level in 2015 and 2016, they still pose a problem for businesses. Exploit kits are web-based apps that are loaded onto websites controlled by cybercriminals – either their own sites or sites that have been hijacked.
Exploit kits contain code that exploits vulnerabilities in web browsers, plugins and browser extensions. When a user with a vulnerable browser visits a malicious URL containing an exploit kit, the vulnerability is exploited and malware is downloaded.
With browsers becoming more secure, and Flash being phased out, it has become much harder to infect computers with malware via exploit kits and many threat actors have moved on to other methods of attack. However, some exploit kits remain active and still pose a threat.
The exploit kits currently in use – RIG for example – contain multiple exploits for known vulnerabilities. Most of the vulnerabilities are old and patches have been available for months or years, although zero-day vulnerabilities are occasionally uploaded. Exploit kits are also updated with recently disclosed proof-of-concept code. Exploit code for two recently discovered vulnerabilities: one in Internet Explorer (CVE-2018-8174) and one in Adobe Flash (CVE-2018-4878) have been added to EKs already.
Keeping browsers and plugins up to date and using a top antivirus solution will provide a good level of protection, although businesses can further enhance security by using a web filter. Web filtering for businesses ensures that any attempt to access a website known to host an exploit kit will be blocked.
Blocking Phishing Attacks
Phishing is one of the biggest threats faced by businesses. Phishing is a method of obtaining sensitive information by deception, such as impersonating a company in an attempt to obtain login credentials or to fool employees into making wire transfers to bank accounts controlled by criminals.
A spam filter can prevent the majority of malicious messages from reaching inboxes, although some phishing emails will make it past the perimeter defenses, especially emails containing links to malicious websites. A web filter provides an additional level of protection against phishing by preventing users from visiting malicious websites sent via email and social media posts. When an attempt is made to visit a known malicious website, access will be blocked, and the user will be directed to a block screen.
A web filter can also be used to enforce safe search on search engines such as Google, Yahoo, and Bing. This will help to prevent inappropriate website content from being accessed through search and image search results.
Monitoring Internet Access and Blocking Inappropriate Websites
Employees can waste an extraordinary amount of time on the Internet. Allowing unfettered access to all website content can result in a considerable reduction in productivity. If every employee wastes an hour a day on the Internet instead of working, a company with 100 employees would lose 100 hours a day, 500 hours a week, and 26,000 hours a year. A sizeable loss.
A web filter can be used to block access to websites such as gambling, gaming, and social media sites – all major drains on productivity. Web filters can also be used to monitor Internet activity. When employees are told that the company monitors Internet use, employees will be less likely to spend time surfing the Internet instead of working.
Web filters can also be used to block not-suitable-for-work (NSFW) content such as pornography and will limit company liability by blocking illegal online activities at work, such as the downloading of copyright-protected content via P2P file sharing sites. Web filters can also limit bandwidth hogging activities such as the streaming of audio and video.

The biggest cybersecurity risk for businesses in the United States is employee negligence, according to a recent Shred-It survey of 1,000 small business owners and C-suite executives.
The findings of the survey, detailed in its North America State of the Industry Report, show the biggest cybersecurity risk for businesses is human error such as the accidental loss of data or devices containing sensitive company information.
84% of C-Suite executives and 51% of small business owners said employee negligence was the biggest cybersecurity risk for their business. 42% of small business owners and 47% of C-suite executives said employee negligence was the leading cause of cybersecurity breaches.
Employees are the Biggest Cybersecurity Risk for Businesses in the United States
Employees often cut corners in order to get more done in their working day and take considerable security risks. Even though laptop computers can contain highly sensitive information and allow an unauthorized individual to gain access to a work network, around a quarter of U.S employees leave their computer unlocked and unattended. Documents containing sensitive information are often left unattended in full view of individuals who are not authorized to view the information.
The risks taken by employees are greater when working remotely, such as in coffee shops or at home. 86% of executives and SBOs said remote workers were much more likely to cause data breaches.
88% of C-suite executives and 48% of small business owners said they have implemented flexible working models that allow their employees to spend at least some of the week working off site. A survey conducted on behalf of the Switzerland-based serviced office provider IWG suggests that globally, 70% of workers spend at least one day a week working remotely, while 53% work remotely for at least half of the week.
Adoption of these flexible working practices is increasing, although cybersecurity policies are not being implemented that specifically cover remote workers. Even though a high percentage of workers are spending at least some of the week working remotely, the Shred-It survey shows that more than half of SMBs do not have policies in place for remote workers.
One of the most important ways that business owners and executives can improve their cybersecurity posture is through employee training, especially for remote workers. The provision of security awareness training will help to ensure that workers are aware of the organization’s policies and procedures and are taught security best practices.
However, the survey suggests training is often inadequate or in some cases nonexistent. 78% of surveyed C-suite executives and small business owners said they only provided information security training on policies and procedures once a year. Considering the risk, training needs to be far more frequent. Employees cannot be expected to retain all the information provided in a training session for the entire year. Training should cover the use of strong passwords, locking devices when they are not in use, never leaving portable devices unattended in public areas, safe disposable of electronic and physician data, and Wi-Fi security. Refresher training should be provided at least every six months.
Policies and procedures need to be developed specifically for remote workers, which cover the practices which must be adopted when working outside the office. With so many workers now spending more time working off-site, the probability of portable electronic devices being lost or stolen is greatly increased.
Businesses must ensure they maintain an accurate inventory of all devices used to access their network and implement appropriate security measures to ensure the loss or theft of those devices does not result in a data breach.
Increased use of insecure WiFi networks poses a major problem, greatly increasing the chance of a malware or ransomware download. Appropriate technologies should be implemented to protect remote workers’ devices from malicious software. TitanHQ can help in this regard.
WebTitan Cloud, TitanHQ’s 100% cloud-based web filtering solution can block malware and ransomware downloads and carefully control the websites that remote workers can access on their company-issued and BYOD devices, regardless of where the individual is located: on or off-site.
For more information on WebTitan and how it can protect your remote workers and improve your security posture, contact the TitanHQ team today for further information.
The RIG exploit kit, used on compromised and malicious websites to silently download malware, has been upgraded with a new exploit. Windows Double Kill exploit code has been added to exploit the CVE-2018-8174 vulnerability – a remote code execution vulnerability that was addressed by Microsoft on May 2018 Patch Tuesday.
To protect against exploitation of this vulnerability, Windows users should ensure they have applied the latest round of patches, although many businesses have been slow to update their Windows devices, leaving them vulnerable to attack.
The vulnerability is in the VBScript engine and how it handles objects in the memory. If the vulnerability is exploited, attackers would gain the same level of privileges as the current user, could reallocate memory, gain read/write access, and potentially remotely execute code on a vulnerable device. The vulnerability has been named ‘Double Kill’ and affects all Windows versions.
The Windows Double Kill vulnerability was being actively exploited in the wild when Microsoft released the update on Patch Tuesday. Initially, exploitation of the vulnerability was achieved through phishing campaigns using RTF documents containing a malicious OLE object. If activated, an HTML page was downloaded and rendered through an Internet Explorer library and the VBScript flaw was exploited to download a malicious payload. The attack could also be conducted via a malicious website. In the case of the latter, it does not matter what browser the user has set as default – on unpatched systems the IE exploit could still work.
The Windows Double Kill exploit code was posted online this week and it didn’t take long for it to be incorporated into the RIG exploit kit. End users could be directed to the RIG exploit kit through phishing campaigns, malvertising, web redirects, or potentially could visit malicious sites through general web browsing. In addition to the Windows Double Kill exploit, the RIG exploit kit contains many other exploits for a wide range of vulnerabilities. Any individual that lands on a URL with the kit installed could be vulnerable even if the latest Windows patch has already been applied.
The threat from email-based attacks is also likely to grow. The Double Kill exploit code has also been incorporated into the ThreadKit exploit builder, which is used to create malicious Office documents for use in phishing attacks.
Protecting systems against these types of attacks requires prompt patching, although many organizations are slow to apply updates out of fear of compatibility problems, which could cause performance issues. Consequently, prior to applying patches they need to be fully tested and that can take time. During that time, organizations will be vulnerable to attack.
A web filter – such as WebTitan – provides an additional level of protection while patches are assessed for compatibility. WebTitan provides protection against exploit kits and malware downloads by preventing end users from visiting known malicious sites, either through general web browsing, redirects, or via hyperlinks contacted in phishing emails.
Venture online and you will be faced with a wide range of threats, some of which could result in your bank account being emptied, others could result in sensitive information being exposed and your accounts being hijacked. Then there is ransomware, which could be used to stop you from accessing your data (unless you have backups or pay the ransom payment).
More malicious websites are now being created than legitimate sites, so how can you stay safe online? One solution used by businesses and ISPs is the use of a web filter. A web filter can be configured to restrict access to certain categories of Internet content and block the majority of malicious websites.
While it is possible for businesses or ISPs to purchase appliances that sit between end users and the Internet, DNS filters allow the Internet to be filtered without having to purchase any hardware or install any software. So how does DNS filtering work?
How Does DNS Filtering Work?
DNS filtering – or Domain Name System filtering to give it its full title – is a technique of blocking access to certain websites, webpages, or IP addresses. DNS is what allows easy to remember domain names to be used – such as Wikipedia.com – rather than typing in very difficult to remember IP addresses – such as 22.214.171.124. DNS maps IP addresses to domain names.
When a domain is purchased from a domain register and that domain is hosted, it is assigned a unique IP address that allows the site to be located. When you attempt to access a website, a DNS query will be performed. Your DNS server will look up the IP address of the domain/webpage, which will allow a connection to be made between the browser and the server where the website is hosted. The webpage will then be loaded.
So how does DNS filtering work? With DNS filtering in place, rather than the DNS server returning the IP address if the website exists, the request will be subjected to certain controls. If a particular webpage or IP address is known to be malicious, the request to access the site will be blocked. Instead of connecting to a website, the user will be directed to a local IP address that will display a block page explaining that the site cannot be accessed.
This control could be applied at the router level, via your ISP, or a third party – a web filtering service provider. In the case of the latter, the user – a business for instance – would point their DNS to the service provider. That service provider maintains a blacklist of malicious webpages/IP addresses. If a site is known to be malicious, access to malicious sites will be blocked.
Since the service provider will also categorize webpages, the DNS filter can also be used to block access to certain categories of webpages – pornography, child pornography, file sharing websites, gambling, and gaming sites for instance. Provided a business creates an acceptable usage policy (AUP)and sets that policy with the service provider, the AUP will be enforced. Since DNS filtering is low-latency, there will be next to no delay in accessing safe websites that do not breach an organization’s acceptable Internet usage policies.
Will a DNS Filter Block All Malicious Websites?
Unfortunately, no DNS filtering solution will block all malicious websites, as in order to do so, a webpage must first be determined to be malicious. If a cybercriminal sets up a brand-new phishing webpage, there will be a delay between the page being created and it being checked and added to a blocklist. However, a DNS web filter will block the majority of malicious websites.
Can DNS Filtering be Bypassed?
The short answer is yes. Proxy servers and anonymizer sites could be used to mask traffic and bypass the DNS filter unless the chosen solution also blocks access to these anonymizer sites. An end user could also manually change their DNS settings locally unless they have been locked down. Determined individuals may be able to find a way to bypass DNS filtering, but for most end users, a DNS filter will block any attempt to access forbidden or harmful website content.
No single cybersecurity solution will allow you to block 100% of malicious websites or all NSFW websites, but DNS filtering should certainly be part of your cybersecurity defences as it will allow the majority of malicious sites and malware to be blocked.

There have been significant developments relating to exploit kits in the past few days. The threat actors behind the Magnitude exploit kit have now changed their malicious payload, and the EITest malware distribution network that directed traffic to exploit kits has finally been sinkholed.
Magnitude Exploit Kit Switches to GandCrab Ransomware Delivery
Exploit kit activity is at a fraction of the level of 2015 and 2016, and in 2017 there was a 62% reduction in the development of exploit kits according to research from Recorded Future.
However, exploit kit activity has not fallen to zero and the malicious code is still widely used to deliver malware and ransomware underscoring the continued need for technologies to block these attacks such as web filtering solutions and the continued need to keep on top of patching.
Exploit kits often leverage vulnerabilities in Java and Adobe Flash, although more recently it has been Microsoft vulnerabilities that have been exploited due to the fall in Java vulnerabilities and the phasing out of Adobe Flash.
One exploit kit that is still being used in extensive attacks, albeit attacks that are highly geographically targeted, is the Magnitude exploit kit.
For the past seven months, the Magnitude exploit kit has been delivering the Magniber ransomware payload almost exclusively in South Korea. However, there has been a notable change in the past few days with it also being used to distribute GandCrab ransomware, with the latter not restricted geographically and capable of infecting English language Windows devices.
While early variants of GandCrab ransomware were cracked and free recovery of files was possible, there is no known decryptor for the current version of GandCrab ransomware being distributed via Magnitude. While Adobe Flash and Microsoft exploits were commonly used, Magnitude is now using a fileless technique to load the ransomware. This technique makes it much harder to detect.
According to Malwarebytes, “The payload is encoded (using VBScript.Encode/JScript.Encode) and embedded in a scriplet that is later decoded in memory and executed.” Once run, the payload is injected into explorer.exe, files are encrypted, and the infected device is rebooted.
EITest Malware Distribution Network Disrupted
There has been some major good news on the exploit kit front this week with the announcement that the EITest malware distribution network has finally been sinkholed. EITest has been active since at least 2011 and has been used to distribute all manner of malware over the years.
EITest was a major distribution network responsible for countless Kronos, Ramnit, DarkCloud and Gootkit infections, although more recently was used to deliver ransomware variants such as CryptXXX and Cerber and send users to sites running social engineering and tech support scams.
Prior to being sinkholed, EITest was redirecting as many as 2 million users a day to a network of more than 52,000 compromised websites that had been loaded with exploit kit code and social engineering scams. Most of the compromised sites were WordPress sites based in the USA, China, and Ukraine.
The threat actors behind EITest were selling traffic to other actors in blocks of between 50,000 and 70,000 visitors at a cost of $20 per thousand.
Over a 20-day period since EITest was sinkholed, more than 44 million users were directed to the sinkhole rather than malicious websites.
Now all redirects to malicious websites have stopped. The compromised websites remain active, but rather than redirecting users to malicious domains they are directing traffic to benign domains controlled by abuse.ch and brilliantit.com.
Regardless of the size of your business, the most effective security measure to deploy to block threat actors from gaining access to your servers, workstations, and data is a hardware firewall. A hardware firewall will ensure your digital assets are well protected, but how should your firewall be configured for optimal network security? If you follow network segmentation best practices and set up firewall security zones you can improve security and keep your internal network isolated and protected from web-based attacks.
Network Segmentation Best Practices
Most businesses have a well-defined network structure that includes a secure internal network zone and an external untrusted network zone, often with intermediate security zones. Security zones are groups of servers and systems that have similar security requirements and consists of a Layer3 network subnet to which several hosts connect.
The firewall offers protection by controlling traffic to and from those hosts and security zones, whether at the IP, port, or application level.
There is no single configuration that will be suitable for all businesses and all networks, since each business will have its own requirements and necessary functionalities. However, there are some network segmentation best practices that should be adopted.
Suggested Firewall Security Zone Segmentation
In the above illustration we have used firewall security zone segmentation to keep servers separated. In our example we have used a single firewall and two DMZ (demilitarized) zones and an internal zone. A DMZ zone is an isolated Layer3 subnet.
The servers in these DMZ zones may need to be Internet facing in order to function. For example, web servers and email servers need to be Internet facing. Because they face the internet, these servers are the most vulnerable to attack so should be separated from servers that do not need direct Internet access. By keeping these servers in separate zones, you can minimize the damage if one of your Internet facing servers is compromised.
In the diagram above, the allowed direction of traffic is indicated with the red arrows. As you can see, bidirectional traffic is permitted between the internal zone and DMZ2 which includes the application/database servers, but only one-way traffic is permitted between the internal zone and DMZ1, which is used for the proxy, email, and web servers. The proxy, email, and web servers have been placed in a separate DMZ to the application and database servers for maximum protection.
Traffic from the Internet is allowed by the firewall to DMZ1. The firewall should only permit traffic via certain ports (80,443, 25 etc.). All other TCP/UDP ports should be closed. Traffic from the Internet to the servers in DMZ2 is not permitted, at least not directly.
A web server may need to access a database server, and while it may seem a good idea to have both of these virtual servers running on the same machine, from a security perspective this should be avoided. Ideally, both should be separated and placed in different DMZs. The same applies to front end web servers and web application servers which should similarly be placed in different DMZs. Traffic between DMZ1 and DMZ2 will no doubt be necessary, but it should only be permitted on certain ports. DMZ2 can connect to the internal zone for certain special cases such as backups or authentication via active directory.
The internal zone consists of workstations and internal servers, internal databases that do not need to be web facing, active directory servers, and internal applications. We suggest Internet access for users on the internal network to be directed through an HTTP proxy server located in DMZ 1.
Note that the internal zone is isolated from the Internet. Direct traffic from the internet to the internal zone should not be permitted.
The above configuration provides important protection to your internal networks. In the event that a server in DMZ1 is compromised, your internal network will remain protected since traffic between the internal zone and DMZ1 is only permitted in one direction.
By adhering to network segmentation best practices and using the above firewall security zone segmentation you can optimize network security. For added security, we also recommend using a cloud-based web filtering solution such as WebTitan which filters the Internet and prevents end users from accessing websites known to host malware or those that contravene acceptable usage policies.
