Our Internet security news features the latest press releases from the world´s largest online security companies with details of the latest threats to be aware of and, unfortunately, Internet security news relating to significant data breaches. While some organizations will be grateful for the advanced warning of an online threat – and details of how to protect themselves against it – for some the warnings will come too late.
Consequently it is recommended to be protected against all manner of online threats with an email filter and web filter from TitanHQ. Our Internet security solutions prevent users from accessing unsafe sites via phishing emails and malvertising, and from visiting websites that are vulnerable to exploit kits and malware. As many organizations already using TitanHQ solutions would agree, it is better to be safe than sorry.
Cybercriminals are constantly developing new tactics to trick individuals into divulging sensitive information or installing malware. One of the latest tactics to be observed is the use of QR codes to direct people to malicious websites where sensitive information is harvested or to sites hosting malware.
A QR code is a machine-readable matrix barcode that is often used for tracking products in a supply chain, but in recent years has been adopted as a convenient way to direct people to web resources without them having to enter a URL or click a link. QR codes have been widely adopted during the COVID-19 pandemic for carrying out contactless operations, such as registering attendance at a venue and for viewing menus in restaurants to help prevent the spread of COVID-19.
Many smartphones have in-built QR code readers and apps can be downloaded for free to allow QR codes to be read. When a smartphone camera picks up a QR code, the user will be directed to whatever web resource has been programmed into the code. While QR codes have many important uses, QR codes can be easily tampered with to direct individuals to malicious websites.
Phishing emails often contain links to malicious websites that have been masked by changing the text in the hyperlink. Hovering a mouse arrow over the hyperlink on a computer will display the URL to which the user will be directed; however, with a QR code the user may be instantly directed to the website and could be prompted to enter their banking credentials, Microsoft 365 credentials, or other sensitive information.
Since QR codes are often used to direct individuals to hosted files, such as PDF restaurant menus, it would be easy to trick people into downloading malicious files through QR codes. The malware could provide a cybercriminal with access to the victim’s mobile device, allowing them to steal sensitive information such as passwords or bank account information.
Many businesses use QR codes to direct customers to websites where payments can be processed, and the use of QR codes for this purpose has increased significantly during the pandemic to avoid contact with Point-of-Sale card readers. QR codes could be abused to direct customers to malicious websites that mimic those used by the business in order to steal payment card information.
The Federal Bureau of Investigation (FBI) has recently issued a warning about the increase in the use of QR codes for conducting malicious activities. The FBI emphasized that QR codes are not malicious in nature but can be abused, so precautions should be taken when using QR codes and not to assume that QR codes are secure.
A study conducted by Ivanti in 2021 revealed 87% of people felt secure conducting financial transactions using QR codes. Given the rise in abuse of QR codes, that confidence is worrying. As with embedded hyperlinks in emails, it is important to exercise caution and to check the URL of the resource that the user is directed to before taking any actions. The domain should be checked to ensure it is correct, and care should be taken to look for any typos or misplaced or substituted letters.
The FBI recommends checking a QR code before scanning to make sure it has not been doctored with, such as by overlaying a sticker on the original QR code. If prompted to download a file after using a QR code, be aware that the file may be malicious. If prompted to download an app, it is more secure to visit an official app store. It is also not necessary to download a QR scanner on most mobile phones, as this increases risk. The apps may be malicious, and many automatically direct users to a resource without requiring confirmation or providing information about the URL that the user will be directed to.
Businesses can protect their corporate-owned devices against QR code scams by installing a web filter. A web filter such as WebTitan can be used to prevent mobile devices from being used to visit malicious websites or web pages that violate acceptable internet usage policies. WebTitan will protect against any redirect to a malicious website, whether via a link in a phishing email or QR code and will also block malware downloads and potentially malicious files.
A phishing campaign has been identified that uses spoofed unemployment benefits websites to trick people into disclosing sensitive personal and financial information. These websites have been designed to closely resemble official U.S. government websites that are used to apply for unemployment benefits.
Individuals arriving on the websites are prompted to enter personal and financial information as part of the claims process. The information provided can be used by the scammers to file fraudulent unemployment benefits claims and have payments directed to their accounts. The credentials and information harvested through the sites can also be used or sold to other cybercriminals to commit identity theft and fraud, with some of the sites used for installing malware onto victims’ devices, including ransomware.
The U.S. Federal Bureau of Investigation (FBI) has received an increased number of complaints about these scams through its Internet Crime Complaints Center in recent weeks, prompting the FBI to issue an alert about the scams. At the time of issuing the alert, the FBI had identified 385 domains hosted on the same IP address, 8 of which impersonated official government websites that host unemployment benefit platforms. Those sites have an .xyz top-level domain (TLD) rather than .gov, and mostly impersonate state-level websites.

The malicious websites include employ-nv[.]xyz, gov2go[.]xyz, illiform-gov[.]xyz, mary-landgov[.]xyz, and newstate-nm[.]xyz, which were all still active at the time of the alert, along with employ-wiscon[.]xyz, marylandgov[.]xyz, and newstatenm[.]xyz which are no longer active.
Campaigns such as this are nothing new, but the number of complaints received about the scams is increasing, as are the number of reported cases of identity theft. Figures from the U.S. Federal Trade Commission show identity theft reports doubled between 2019 and 2020, with more than 1.4 million reports received last year.
Several steps can be taken to avoid becoming a victim of these scams. It is important to exercise caution when visiting any website and ensure that the spelling of the web address is correct, and the website has a .gov TLD. The U.S. government does not use .xyx TLDs on its websites.
While the padlock icon next to a URL is a sign that the site has an SSL certificate and the connection between the website and the browser is secure, it does not indicate the website is genuine. Cybercriminals often obtain SSL certificates for their websites to make them appear to be legitimate. The padlock should be present before any sensitive data is disclosed to avoid interception of that information, but other checks should be performed to make sure the site is genuine.
Malware downloads can be blocked by using antivirus software, which should be set to update automatically. Any security updates should be applied promptly, and browsers and plugins regularly updated to the latest version. To prevent stolen credentials from being used to access accounts, multi-factor authentication should be implemented and strong passwords should be set on accounts.
It is important to stop and think before taking any action suggested on a website or in an email. In the case of the latter, never open attachments in emails or click links to websites in messages from unknown individuals. Even if an email appears to have been sent by a trusted individual, checks should be performed on the email header information, especially in unsolicited messages.
Many of these campaigns target individuals, but employees are often targeted in phishing attacks that seek email credentials and other sensitive business information. In addition to providing security awareness training to the workforce and implementing an advanced email security solution such as SpamTitan, businesses should consider implementing a web filter.

To those unfamiliar with DNS filtering, it is a form of web filtering that is used to filter out unwanted and undesirable web content, whether that is webpages containing objectionable material such as pornographic images or cyber threats such as websites used for phishing or malware distribution.
The Domain Name System (DNS) is what makes it possible for websites to have easy-to-remember domain names. A domain name, such as google.com, is easy for people to remember, but no use to a computer, which requires an IP address to find that resource on a remote server. The DNS is used to convert a domain name into its corresponding IP address, and DNS filtering is web filtering that takes place at the DNS lookup stage of a web request before a connection is made to the server hosting the web content.
DNS Filtering Myths
DNS filtering has several advantages over standard web filtering. Filtering occurs before any content is downloaded, which is better for speed and security. With DNS filtering, there is next to no latency – page load speeds are unaffected.
Many businesses fail to appreciate the importance of DNS filtering, after all, what is the point of blocking malware and ransomware threats on the Internet when antivirus software is installed on all end points? While AV software is effective at blocking known malware threats, it will not block new threats that have not been seen before, as the signatures of those malware variants are not in the virus definition lists of AV software. New variants of old malware versions are constantly being released to bypass signature-based AV defenses, so additional protection is needed. DNS filters can block these threats based on the reputation of IP addresses and will block downloads of file types associated with malware.
DNS filtering also improves defenses against phishing attacks, which all too commonly result in costly data breaches. Phishers are constantly devising new methods to get their emails into inboxes and trick end users into clicking on links and disclosing their credentials. Spam filters will block most of these messages but not all, and security awareness training only goes so far. A web filter will block access to phishing content and can significantly improve an organizations’ phishing defenses. When links to phishing websites are clicked the request is blocked and DNS filter logs will show which links were clicked. That can help to improve the effectiveness of spam filters and security awareness training programs.
DNS filters are also used for content control. Most businesses will have acceptable Internet usage policies in place, and employees will be aware of the risks of accessing prohibited web content, but DNS filters are ideal for enforcing those policies. Thew can prevent lawsuits from downloads of copyright infringing cracked software and other pirated content onto business network or users’ devices.
There is a common misconception that DNS filtering is complicated and time consuming when that is not the case. A DNS filtering solution is actually very quick and easy to configure. Simply point the DNS to the service provider, and you can set your filtering controls quickly and easily through the user interface. WebTitan for instance can be up and running in around 30 minutes and after the initial set up and little ongoing maintenance is required.
Another common misconception is that DNS filters are easy to bypass. While no web filtering solution is impossible to bypass, it is fairly easy to ensure that most users will not be able to bypass the filtering controls. You just need to configure the solution to block proxies and anonymizers and lock down the DNS settings. It is also recommended to block DNS requests to anything other than your approved DNS service at the firewall for good measure.
If you have your own, locally hosted, internal DNS server, you should allow only port 53/UDP outbound requests from your internal DNS server’s internal IP address to the external IP addresses of the primary and secondary DNS servers that your internal DNS server is configured to use. That means local computers query your local DNS server, and only your DNS server queries the web filtering DNS service on the Internet.

Ransomware gangs have been feeling the heat following the DarkSide ransomware attack on Colonial Pipeline in May that forced the company to shut down its fuel pipeline serving the U.S. East Coast for a week. Any attack on critical infrastructure is likely to draw a response from the U.S. government, so it is no surprise that ransomware gangs faced a great deal of scrutiny after the attack. The DarkSide group shut down following the attack, and several other ransomware gangs went quiet.
DoppelPaymer was one of the gangs that appeared to be laying low. Around a week after the Colonial Pipeline attack the group went quiet and no further updates were posted on the group’s data leak site after May 6, 2021.
It is not uncommon for ransomware operations to go quiet for a few weeks, but they usually return. In many cases, the threat group reappears with a tweaked ransomware variant that is used under a new name, as has happened with DoppelPaymer.
DoppelPaymer attacks often start with a phishing email with links or attachments that install other malware variants, which in turn deliver the ransomware payload. Prior to the Emotet botnet being shut down, that banking Trojan was used to deliver DoppelPaymer, as well as Dridex.
Security researchers investigating a new ransomware-as-a-service operation called Grief (PayorGrief) that appeared in June identified striking similarities between Grief and DoppelPaymer, leading them to the conclusion that they are one and the same. A sample of the malware was found that dates back to May 17, indicating the group had only stopped attacks for a very short period of time.
Grief and DoppelPaymer both have the same encrypted file format and are both distributed in phishing emails via the Dridex botnet, with one of the analyzed Grief samples also found to link to the old DoppelPaymer portal, although the samples identified since point to a separate Grief RaaS portal. Analyses of the code and the leak site also revealed further similarities such as the use of identical encryption algorithms and matching General Data Protection Regulation (GDPR) warnings for non-paying victims about GDPR penalties. The group appears to have been quite active in the short time since the new RaaS was launched, with 12 victims already listed on the group’s data leak site.
The best way to protect against DoppelPaymer ransomware attacks is to concentrate on blocking the initial attack vector – the phishing emails that deliver Dridex, which in turn delivers the ransomware. That requires an advanced anti-spam solution with machine learning capabilities and sandboxing. SpamTitan has these capabilities and many more detection mechanisms that ensure 100% of known malware threats are identified and blocked and new malware threats are identified even before their signatures are known.

A new malware dubbed Crackonosh is being used in attacks on gamers with the goal of hijacking the resources on their computers to turn them into cryptocurrency mining rigs.
Cryptocurrency prices have been soaring in recent months, with many reaching record prices. That makes mining cryptocurrency profitable, and even more so when using the powerful computers of gamers without their knowledge. The gamers cover the electricity costs and supply the hardware, while the coin mining profits go to the scammers.
Getting malware onto gamers’ devices is the key to this scam, and what better way to do that than to offer gamers free versions of popular games such as Grand Theft Auto V, Pro Evolution Soccer 2018, or NBA 2K19. These cracked games can be installed without having to make a purchase, with the games offered free in forums. Currently, most infections have come via forums, but games could easily be hosted on a website and traffic driven to those sites through malicious adverts in the search engines or third-party ad blocks on any number of high traffic websites.
The games are legitimate, although they have been cracked to allow them to be installed without having to purchase the game key. The correct game will be installed but bundled into the installer are several other files that will execute in the background and install Crackonosh malware, which is capable of disabling certain antivirus programs to ensure it is not detected, including Windows Defender. It also disables Windows Update to ensure that Windows Defender is not reactivated. Since the malware creates and stores an icon in the system tray, the user will most likely be unaware that their antivirus software has been disabled.
One of the main aims of Crackonosh malware is to deliver a legitimate cryptomining program named XMRig, although in this case, XMRig is used to hijack the CPU and GPU of victims’ devices and use those resources for generating cryptocurrency. Using XMRig on one gaming computer will not make much money, but at scale the operation is hugely profitable.
The malware distribution campaign has proven successful, with the malware found in more than a dozen countries, with the highest numbers of infected computers in the Philippines, Brazil, India, Poland, United States, and the United Kingdom. As of December 2020, there were more than 220,000 devices infected with Crackonosh malware and those devices had been used to generate at least $2 million in Monero coins at today’s prices.
This malware campaign targets gamers as their computers are well suited to mining cryptocurrency. Once infected, users are likely to experience a serious reduction in performance and much higher electricity bills, but cryptocurrency mining can also cause computers to overheat, components can wear out from overuse, and devices will ultimately fail.
It is not only cryptocurrency mining malware than can be installed along with cracked software. Any number of other malware variants could be delivered. Another recently identified campaign also uses cracked software as the cover but delivers a malware loader dubbed MosaicLoader. MosaicLoader is used to deliver cryptocurrency miners as well as Remote Access Trojans, cookie stealers, backdoors, and any other malware than the MosaicLoader operator sees fit to deliver.
Installing cracked software and games carries a risk of malware infections, and that is particularly bad news for businesses, especially those that have a BYOD policy or allow their employees to work remotely on corporate-issued devices.
Preventing malware infections such as Crackonosh or MosaicLoader should start with education. Employees should be told about the risks of installing cracked software or other unauthorized software on devices. Technical measures are also required. To block downloads from the Internet, it is worthwhile installing a DNS filter. DNS filters can be used to block content at the DNS lookup stage of a web request, before any content is downloaded.
They can block access to certain categories of websites – gaming sites and forums for examples – or specific files from being downloaded, such as game and software installers. DNS filters also use a variety of methods to assess whether sites are malicious and will block access to URLs and IP addresses known to be used for illegal and malicious purposes.
If you want to improve your defenses against malware, contact TitanHQ today. TitanHQ’s advanced spam filtering solution – SpamTitan – and DNS filter – WebTitan – block malware at source and keep you protected from phishing, ransomware, and other email and web based threats.
Ransomware is now one of the biggest threats faced by businesses. When hackers gain access to business networks, it is now common for large quantities of data to be stolen prior to file encryption. Ransomware gangs know all too well that businesses with good backup policies will be able to restore their encrypted data from backups, but they will need to pay the ransom in order to prevent the release or sale of the stolen data. Even when files can be recovered from backups, many businesses feel they have no alternative other than paying the ransom to ensure stolen data are deleted. Data from Coveware indicates 70% of ransomware attacks now involve data theft.
Ransomware attacks are incredibly costly, even if the ransom is not paid. Universal Health Services Inc. in the United States suffered a Ryuk ransomware attack in September 2020 and the health system choose not to pay the ransom. Add up the recovery costs which included data restoration, cybersecurity consultants, notification letters to patients, and the loss of many services during the remediation process, and the cost of the attack rose to $67 million.
While expensive, that high cost is just a fraction of the cost of the recent Conti ransomware attack on Ireland’s Health Service Executive. The May 2021 ransomware attack caused massive disruption to healthcare services in Ireland. Without access to patient records, patient safety was put at risk, non-urgent appointments had to be cancelled, and there were major delays getting test results.
A few days after issuing a ransom demand of €20 million, the Conti ransomware gang gave the HSE the decryption tools free of charge. Even with the valid tools to decrypt data, recovery has been slow and incredibly costly. It has been around a month since the tools were provided to decrypt files, but many systems are still inaccessible. HSE Chief executive Paul Reid said it is likely to take months before all systems are brought back online.
Simply eradicating the attacker from the network and recovering encrypted data is only part of the story. IT systems need to be upgraded, security greatly improved, and a security operation center needs to be set up to monitor the network to prevent any further attacks. The initial costs incurred as a result of the attack were reported to be well over €100 million, but the overall cost of the attack is expected to rise to around half a billion Euros – Around $600 million.
An attack on such a major healthcare provider is naturally going to be incredibly costly, but ransomware attacks on small businesses can be catastrophic. Following a ransomware attack, an estimated 60% of small businesses fail within 6 months. One study showed the cost of remediating a ransomware attack doubled between 2020 and 2021, with the average cost now around $1.85 million. Attacks are also increasing. An analysis of the data leak sites used by ransomware gangs by cybersecurity firm Mandiant showed there has been a 422% increase in ransomware-related data leaks between Q1, 2020 and Q1, 2021.
How to Improve Your Defenses Against Ransomware
The most prolific ransomware gangs operate under the ransomware-as-a-service model. The creators of the ransomware do not conduct attacks, instead they employ affiliates to do they attacks for them. That means more attacks can be conducted. The creators run the operation and take a cut of any ransom payments generated, with the affiliates retaining the bulk of the ransom payments from their attacks.
Affiliates conduct attacks using a variety of methods and no two attacks will be exactly the same. Preventing ransomware attacks therefore requires a range of different measures to block all of the attack vectors, but the best place to start is by improving phishing defenses. Phishing emails are increasingly used as the initial entry point into business networks, so if these malicious emails can be blocked at the email gateway, they will not be delivered to inboxes where they can be opened by employees.
That is an area where TitanHQ can help. TitanHQ has developed two advanced solutions that are effective at preventing ransomware attacks. SpamTitan is a powerful email security solution that filters out malicious messages to stop them from causing harm. Rather than be delivered, emails with malicious links and attachments are quarantined.
WebTitan is a DNS-based web filtering solution that complements SpamTitan to provide even greater protection against ransomware and malware attacks. WebTitan prevents employees from visiting the malicious websites where malware and ransomware are downloaded.
Both solutions are consistently given top marks on software review sites such as G2 Crowd, with the solutions given a maximum of 5 stars by users of Spiceworks and Capterra. SpamTitan has also received over 37 consecutive Virus Bulletin Spam awards.

TitanHQ has announced a new version of WebTitan Cloud has been released that brings new features and improved security.
The release of WebTitan Cloud version 4.16 has allowed TitanHQ to introduce a new web filtering solution for the education sector – WebTitan OTG (on-the-go) for Chromebooks.
The use of Chromebooks has been steadily increasing, especially in the education sector where they are a cost-effective option for schools to allow students to access the Internet. Internet access is important in education, but it is vital that students can access the Internet safely and securely. Controls need to be implemented to prevent students from accessing age-inappropriate content such as pornography, devices need to be protected from malware and ransomware, and phishing and other malicious websites should be blocked.
WebTitan OTG for Chromebooks allows IT professionals in the education sector to easily implement web filtering controls for individuals, user groups, or globally to ensure compliance with federal and state laws, including the Children’s Internet Protection Act (CIPA) and protect their students and their devices from threats.
WebTitan OTG for Chromebooks, like other WebTitan products, is a DNS-based web filter that applies filtering controls at the DNS lookup stage of web requests. That means there is no latency – Internet speed is unaffected. Since WebTitan is entirely cloud-based, there is no need for any additional hardware and the solution requires no proxies or VPNs.
Set up is easy and user and device level web filtering for Chromebooks can be set up in just a few minutes. The solution provides protection for students regardless of where the Internet is accessed – students will have access to a clean, safe, filtered Internet in the classroom and at home, and it is also easy to lockdown Chromebooks to prevent any bypassing of filtering controls. Administrators also have full visibility into Internet access, including locations, web pages visited, and attempts made to visit prohibited content.
Using WebTitan OTG for Chromebooks provides an effective way to apply filtering policies to your Chromebooks from the cloud.
Support Added for in Azure Active Directory
WebTitan Cloud version 4.16 includes DNS Proxy 2.06, which supports filtering of users in Azure Active Directory, as well as on-premise AD and directory integration for Active Directory, with further directory services due to be added to meet customers’ need.
Current WebTitan customers will be automatically updated to the latest version of WebTitan Cloud and will have instant access to the new features and the latest fixes will be applied automatically.
“This new release comes after an expansive first quarter. The launch of WebTitan Cloud 4.16 brings phenomenal new security features to our customers,” Said TitanHQ CEO, Ronan Kavanagh. “After experiencing significant growth in 2020, TitanHQ expects these product enhancements and new features to make 2021 another record-breaking year.”
The pandemic forced many businesses to accelerate their digital transformation strategies to support an at home workforce and survive the pandemic; however, this new approach to working was not without risk.
Cybercriminals took advantage of companies that failed to address vulnerabilities, with some of the most widely exploited vulnerabilities in 2020 in remote access solutions such as the Pulse Secure VPN. Brute force attacks against Remote Desktop Protocol skyrocketed as more businesses switched to remote working, and while many businesses have opened their offices once again, the brute force attacks are still occurring at levels far above those before the pandemic.
Threat actors also stepped up their attacks on remote workers early on in the pandemic and attacks are continuing as lockdowns persist and employees continue to work from home. Many businesses address these risks through security awareness training and teach employees cybersecurity best practices and how to identify threats such as phishing. A little security awareness can go a long way and can be the difference between a threat being recognized and avoided or a link in a phishing email being clicked without thinking by an employee.
There are many threats that businesses may not be aware of, one of which was highlighted by a recent YouGov survey. Throughout a large part of the pandemic, schools have been closed and children have been home schooled. The survey revealed a quarter of UK workers have allowed their children to use their corporate device as part of home schooling and for other purposes such as socializing and gaming.
An employee may be aware not to engage in risky online activities, but children using work devices for Internet access leaves businesses vulnerable to cyberattacks. The survey, conducted on 2,000 UK employees, also revealed 70% of employees could access social media websites on their corporate devices and despite being one of the most fundamental aspects of security, 74% of employees said they did not use a unique password for all accounts.
During the pandemic when employees are isolated and may ben struggling with home schooling as well as working, it is understandable for employers to take a more relaxed view on the use of work computers for non-work purposes, but risks do need to be managed. Having no visibility into Internet access and failing to implement any controls over the content that can be accessed by remote workers and other household members on work laptops is a serious risk, and one that could easily lead to a malware or ransomware attack.
One of the ways that security can be improved for remote workers is to place certain restrictions on uses of corporate laptops with a web filter. A web filter such as WebTitan gives IT teams visibility into the sites that their employees are accessing, which allows them to identify potential risks and apply controls to reduce those risks to an acceptable level.
WebTitan can be used to prevent downloads of certain file types to reduce the risk of a malware infection and to block access to high-risk websites, such non-sanctioned file sharing services. Categories of website can be blocked at the click of a mouse, such as social media websites, and it is straightforward to block messenger services.
WebTitan is a powerful, yet easy to use security solution that is easy to apply to protect devices issued to employees no matter where they work and can greatly improve security with a remote workforce as well as when employees return to the office.

DNS filtering – or Domain Name System filtering to give it its full title – is a technique of blocking access to certain websites, webpages, and IP addresses. The 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 184.108.40.206. The DNS maps IP addresses to domain names to allow computers to find web resources.
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 your browser to make a connection to the web server where the website is hosted. The webpage will then be loaded. The actual process involves several different steps, but it is completed in a fraction of a second.
So how does DNS Web 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. DNS blocking occurs if a particular webpage or IP address is known to be malicious. The DNS filter will use blacklists of known malicious websites, previous crawls of new websites and web pages, or web content will be assessed in real time if the web page or website has not previously been crawled and categorized. If the website trying to be accessed is determined to be malicious or otherwise violates pre-defined policies, instead of the user being connected to the website, the browser will be directed to a local IP address that displays a block page explaining why the site cannot be accessed.
This control could be applied at the router level, via your ISP, or by 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 and access to those sites is prevented.
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 up 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 blacklist. However, a DNS web filter will block the majority of malicious websites.
The purpose of a web filter is to reduce risk, not eradicate it entirely. Since the vast majority of malicious web content will be blocked, risk can be significantly reduced and there will only be a low chance of a website being accessed that violates your policies.
Can a DNS Filtering Service be Bypassed?
The short answer is yes. Proxy servers and anonymizer sites could be used to mask traffic and bypass the DNS filter. Your DNS filtering service should allow you to easily block access to anonymizer websites and prevent the use of proxy servers and virtual private networks (VPNs). Configuring the DNS filtering service to block access to these services will prevent all but the most determined employees from bypassing the DNS filtering service.
The other key way of bypassing a DNS filtering service is to manually change the DNS settings locally, so it is important for these settings to be 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.
There may be a legitimate need to bypass a DNS filtering service. Some DNS content filtering solutions have a feature that allows administrators to temporarily remove content filtering controls. WebTitan Cloud uses cloud keys for this. The cloud key can be issued to a user to bypass content filtering settings for a set time period, such as if research needs to be conducted.

DNS Content Filtering for CIPA Compliance
Schools and libraries in the United States are required to comply with the Children’s Internet Protection Act (CIPA) in order to receive E-rate discounts and qualify for federal grants. There are several requirements of CIPA, one of the most important being to block or filter Internet access to prevent access to images that are obscene, involve child pornography or child abuse, or could otherwise be harmful to minors.
DNS content filtering is the easiest and most cost-effective way of complying with this requirement of CIPA and applying content filtering controls for both wired and Wi-Fi networks. DNS content filtering solutions require no hardware purchases, no software needs to be installed, and they are easy to implement and maintain. DNS content filtering solutions have highly granular filtering controls and allow precision control over content, without overblocking.

What 3 things are most important about employee internet access?
Employees need internet access to complete their work duties, but it is essential to develop an acceptable Internet usage policy and get employees to sign it, that policy should be enforced using a web filtering solution, and you should have a sanctions policy for when employees violate the rules.
What is best, a web filtering appliance of cloud-based web filter?
Both options will provide clean, safe Internet access, but cloud-based web filtering does not require the purchase of a costly appliance, it is more flexible and scalable, and there is no patching burden. For SMBs and MSPs, cloud-based web filtering is the easiest and most cost-effective Internet filtering solution.
Does web filtering slow Internet speed?
Some web filtering solutions involve a degree of latency, but a DNS filtering solution will not slow internet speed as all filtering takes place at the DNS lookup stage of a web request before any content is downloaded. Filtering occurs in the same time as it takes to perform a standard DNS lookup so there is no latency.
How can I provide DNS filtering as a managed service as an MSP?
Adding the WebTitan DNS filtering service to your service stack couldn’t be easier. WebTitan is can be set up in minutes, APIs allow easy integration into your existing back office systems, you will be provided with a white label version ready to take your branding, and you can even host the solution in your own environment.
How much does DNS content filtering cost?
There is considerable variation in price between different web filtering solutions. The most expensive solution will not necessarily be the best option for your business. Price depends on contract term, the number of users, and add-ons. TitanHQ’s DNS content filtering solution, WebTitan, typically costs around $1 per user, per month.
A phishing campaign is underway which is distributing a new variant of the DanaBot Trojan. The DanaBot Trojan was first identified in May 2018 and has been actively distributed via phishing emails for more than two years. In the summer of 2020, activity slowed but the campaigns resumed in October.
DanaBot is a modular banking Trojan used in targeted geographical attacks on businesses. The first variant that emerged in 2018 was used in targeted attacks in Australia, while the second variant was primarily used in attacks on U.S. companies. Attacks have also been conducted in Europe, primarily in Ukraine, Austria, Poland, Italy, and Germany.
The latest variant is the fourth to be identified and has been released around a year after the third variant was identified in February 2019. The latest variant has had several technical anti-analysis changes made to the main component of the malware and its method of maintaining persistence has changed. The latest variant now achieves persistence through a LNK file loaded into the user’s startup folder, which launches the malware when the device is booted.
Affiliates are used to conduct campaigns distributing the DanaBot Trojan under the malware-as-a-service model. Several new affiliate IDs have been added which suggests the malware-as-a-service operation is growing. It is therefore probable that DanaBot will grow into a much bigger threat in 2021.
Previously, DanaBot has been primarily distributed via spam emails that deliver a malware dropper, which downloads the banking Trojan via a multi-stage process. It now appears that the malware is being distributed via websites that offer cracks and software keys for pirated software such as graphics software, VPNs, antivirus software, and games.
Protecting Against Banking Trojans by Blocking Malware Delivery
Protecting against DanaBot and other Trojans requires a range of security measures. Two of the most important are an advanced spam filter and a web filtering solution. The spam filter will detect malicious emails that attempt to deliver the malware dropper, while the web filter will block access to the websites that are used to download the malware.
TitanHQ has developed a spam filtering solution – SpamTitan – that provides protection against known and unknown malware variants and a web filter – WebTitan – that prevents users from accessing malicious websites and categories of website commonly used to distribute malware.
With both of these cost-effective cloud-based cybersecurity solutions implemented, businesses can block the two most common vectors used to distribute malware and keep their networks and devices well protected.

COVID-19 presented many new opportunities for cybercriminals, many of which have proven to be highly successful. In the early days of the pandemic, when it became clear that the new coronavirus was spreading beyond the borders of China and concern about the virus grew, cybercriminals switched from their normal phishing campaigns and started adopting COVID-19 lures.
Phishing campaigns were conducting offering advice about the virus, potential cures, and advice as people craved information that was in short supply. Fake COVID-19 tracking apps and websites were set that collected sensitive information or installed malware, and PPE shortages saw fake shops set up offering non-existent supplies. Then there were fake charities, disinformation campaigns, and phishing scams related to job retention schemes, self-employment income support, government coronavirus loans, and fake tax rebates.
The move to remote working due to the pandemic saw hackers targeting vulnerabilities in remote working solutions such as VPNs and throughout 2020, ransomware gangs have been extremely active, especially in Q3 and Q4, 2020 when attacks soared.
As we move into 2021, cybercriminals are likely to continue to exploit the pandemic to steal credentials, access sensitive data, and spread malware and ransomware, so it is important for businesses not to let their guard drop and to continue to ensure that they have appropriate protections in place to block threats.
The Cyber Threat Landscape in 2021
The high level of ransomware attacks in the last quarter of 2020 is likely to continue in 2021. There are no signs that cybercriminals will reduce attacks, as they are still proving to be profitable. The healthcare industry is likely to continue to be targeted, with cyberattacks on pharmaceutical and clinical research firms also extremely likely.
Now that COVID-19 vaccines have been approved and are starting to be rolled out, cybercriminals have yet another opportunity. The vaccine rollout is likely to take many months and it could well be the autumn or later before most people receive the vaccine. Cybercriminals have already adopted COVID-19 vaccine lures to obtain sensitive information and spread malware and ransomware.
These COVID-19 vaccine scams have impersonated the World Health Organization, Centers for Disease Control and Prevention, and vaccine manufacturers, and are likely to increase over the coming weeks and months. Campaigns have been identified in 2021 that impersonate public health authorities and trick users into clicking links and download files that install Trojans when opened.
We are also likely to see the scams offering financial support, virus information, and infection alerts continue, and offers of fake vaccine can be expected over the coming weeks and months.
One vaccine-related scam to be recently identified involved messages sent to businesses asking recipients to click a link to confirm their email in order to receive the vaccine. Clicking the link directed them to a phishing website where Microsoft 365 credentials were harvested.
Since many employees will continue to work from home in 2021 until the risk of infection is reduced, attacks on remote working infrastructure are also likely to continue.
There is good reason to be hopeful in 2021 now that the vaccines are starting to be rolled out, but it is important for businesses not to let their guard down and to ensure that they have adequate protections in place to identify and block current and new threats.
Many scams are conducted via email, as it is the easiest way for cybercriminals to obtain the credentials they need to gain a foothold in business networks. It is therefore important to ensure that email security is up to scratch and an advanced spam filtering solution is in place that can block phishing and malware threats. If it is possible to implement multi-factor authentication, this should be widely used, especially on email accounts and remote access solutions.
Web filtering solutions are an important cybersecurity measure to deploy to block the web-based component of phishing attacks and to prevent malware and ransomware downloads over the internet. Web filters can be used to block access to known malicious websites and restrict access to risky websites, and cloud-based solutions are easy to deploy to protect both office-based and remote workers.
With many employees still working remotely, it is important to provide regular updates on threats and security awareness training on the threats they are likely to face. Patches and software updates should be applied promptly to prevent cybercriminals exploiting vulnerabilities, especially in remote access solutions such as VPNs which are being actively targeted.
Since ransomware attacks are an ever-present risk, ensure your critical data is regularly backed up and test your backups to make sure data recovery is possible in the event of disaster. A good strategy to adopt is the 3-2-1 approach. Make three backups, store on 2 separate media, and make sure one copy is stored on a non-networked device.
The 2021 threat outlook may be bleak, but with preparation and the above solutions in place, it is possible to prevent most attacks, detect attacks in progress, and recover quickly should an attack succeed.
The notorious cybercriminal organization Evil Corp, which was responsible for the Dridex and Zeus banking Trojans and BitPaymer ransomware, have started using a brand new ransomware called Wastedlocker, so named due to the .wasted extension which is used on encrypted files.
Evil Corp has been relatively quiet in recent months following the indictment of two high-profile members of the group by the U.S. Department of Justice in December 2019 for their role in the creation and distribution of Dridex and Zeus. The group bounced back with relatively low-level campaigns in January, but there has been little activity since. It appears that the time has been spent developing WastedLocker ransomware, which appears to have been mostly written from scratch.
WastedLocker ransomware was first used in May 2020 and is believed to be a replacement for BitPaymer ransomware. In the short space of time that the new ransomware has been in use, attacks have been conducted on at least 31 organizations, according to data from Symantec. Most of the victims are located in the United States, eight of which are Fortune 500 companies and 11 are publicly listed. Attacks have been conducted on companies operating in a wide range of industry sectors, with the manufacturing, information technology, and media and telecommunications sectors experiencing the highest number of attacks.
Evil Corp appears to be targeting large organizations with deep enough pockets to pay the sizeable ransom demand, which has ranged from $500,000 to $10 million in some cases. In contrast to many other ransomware operators, Evil Corp does not steal data prior to file encryption, although that could well change in the future. The group certainly has the technical skill to adopt that tactic, but it appears that they have refrained from doing so to stay under the radar.
In addition to encrypting endpoints, the group is targeting database services, file servers, virtual machines and cloud environments to cause maximum disruption to maximize the probability of the ransom being paid. The group is careful and patient, often waiting several months before their ransomware encryption routine is triggered.
Evil Corp is one of many threat actors to have adopted ransomware, with attacks on businesses having increased over the past few months. Around 15 groups are now conducting manual ransomware attacks in which data is stolen prior to file encryption and threats are issued to publish or sell the stolen data if the ransom is not paid. This tactic has been effective, with around half of businesses paying the ransom.
The University of California San Francisco is one of the latest victims that has been forced to pay the ransom to recover data encrypted in the attack. That ransomware attack involved NetWalker ransomware, and data was stolen in that attack prior to encryption. Without access to essential research data, the university had little option other than paying the $1.14 million ransom.
Organizations are attacked in a variety of ways, often using brute force tactics on RDP or exploiting vulnerabilities in VPNs, but there has also been an increase in email-delivered ransomware and drive-by malware downloads, highlighting the need for advanced email and web security solutions, which is an area where TitanHQ can help.
The massive increase employees working reportedly has not been missed by cybercriminals, who are actively targeting these workers using a variety of tactics to fool them into disclosing their credentials or installing malware. Phishing attacks remain the most common method used to attack remote workers, but there has also been a notable increase in malvertising during the COVID-19 pandemic.
Malvertising is the practice of creating malicious adverts which are syndicated across legitimate websites through third-party ad networks. The malicious adverts are used to redirect website visitors to webpages where credentials are harvested, malware is downloaded, or to other scams to obtain fraudulent payments or charitable donations.
Several COVID-19 themed ploys have been used in these malvertising campaigns to trick people into downloading malware. These scams prey on fears about SARS-CoV-19, often spoofing WHO and other COVID-19 authorities to add legitimacy to the campaigns. A common theme is an offer of important advice on how to protect against COVID-19.
There rise in malvertising activity during the COVID-19 pandemic has been significant, with some reports indicating the number of malicious adverts have doubled in March compared to standard levels of malicious advert activity prior to the pandemic.
A malvertising campaign was recently identified that spoofed the anti-malware software vendor Malwarebytes. The campaign claimed the user’s computer was infected with malware and a download of Malwarebytes’ software was required to remove the infections. The malicious webpage used for the scam was on a malwarebytes-free domain that was registered on March 29, 2020. The site used a copycat template created from stolen branding from the genuine site. Any individual that landed on the website that was using the Internet Explorer browser was redirected to a webpage hosting the Fallout exploit kit that silently downloads the Raccoon information stealer.
There was a major increase in domain registrations related to COVID-19 in March. While not all of these websites are currently being used for nefarious purposes, many are being used for scamming. NTT recently issued an alert stating that around 2,000 COVID-19 domains are being set up each day and there has been a significant rise in phishing attacks directing users to newly registered domains. The TrickBot Trojan accounts for the majority of malware infections from these sites. Figures from Palo Alto Networks’ Unit 42 team show there was a 656% increase in the number of new COVID-19 related domains registered in March.
The increase in web-based attacks calls for improvements to cybersecurity defenses to protect remote employee’s devices from malware infections. A download of malware onto a user’s device could easily see the malware transferred to the network when the user connects.
One of the easiest and most effective ways of blocking these attacks is to implement a web filtering solution such as WebTitan Cloud. With WebTitan Cloud in place, when a user attempts to visit a malicious website, or when an attempt is made to redirect a user through malvertising, rather than arriving on the website the user will be directed to a local block page.
WebTitan Cloud also allows filtering controls to be applied to control the types of websites employees can visit on their corporate-owned devices. Controls can be applied to block access to risky websites such as torrents and peer-to-peer file sharing sites, which are also being used to distribute malware.
WebTitan Cloud is a DNS-based filter that conducts filtering at the DNS lookup stage of a web request. Applying filtering controls and restricting access to certain categories of website involves no latency, which is especially important during lockdown when employees typically have far less bandwidth available than at the office.
WebTitan Cloud does not require the installation of a clients and the solution can be set up and configured in minutes to protect all workers, no matter where they choose to access the internet.

New research has recently been published which suggests there has been a lack of security awareness training for remote workers, even with the massive increase in people working from home due to the COVID-19 pandemic and the increased threat level.
Many companies have had to make major changes to policies and allow most employees to work from home, even though doing so introduces cybersecurity risks. While this is seen by many as a temporary measure due to the pandemic, there is currently some debate about how long lockdown measures will be in place. It could well be many months before lockdowns are eased and there is a return to “normal” working life. It may also be difficult to convince workers to return to the office when measures are eased, or at least until a vaccine for the virus has been developed. That could well be a year or most likely much longer.
In the meantime, remote workers are not just encountering the odd phishing email. These workers are being actively targeted by cybercriminals and APT groups. It is important to ensure that technical controls are up to scratch and are blocking threats but also to train workers to recognize threats such as phishing.
Technical Controls Will Not Block 100% of Cybersecurity Threats
Technical solutions can block most malware and phishing attacks on remote workers and will protect devices and the networks to which those devices connect. TitanHQ has developed two solutions that provide excellent protection from email and web-based threats, and there has been a massive increase in demand for those solutions during the COVID-19 pandemic from businesses and managed service providers (MSPs).
When these solutions are coupled with other cybersecurity protections such as firewalls, antivirus software, and intrusion detection systems, businesses will be well protected; however, no matter how many layers are added to your defenses, security awareness training for remote workers should still be provided. Employees are the last line of defense and require training to help them identify threats that bypass your technical defenses.
Employees are a Weak Link, but Neglecting Security Awareness Training for Remote Workers is a Mistake
One study recently conducted on IT workers by Apricorn revealed 57% of IT decision makers in the United Kingdom believe remote workers are a security risk and will expose organizations to data breaches and that there is apathy among IT leaders about training the workforce as employees are not concerned about security. 34% of IT leaders said their remote workers do not care about security, but that is not a reason not to provide training. It is a reason to reinforce training and get employees to buy into the company’s security strategy.
Another survey, conducted by Promon on 2,000 remote workers in the United Kingdom, confirmed those findings. The study revealed 66% of employees have not been provided cybersecurity training in the last 12 months, even though cybercriminals are actively targeting remote workers. It is also concerning that 77% of respondents were not worried about the security threat from working from home. The survey also revealed that 61% of employees are using personal devices to work from home instead of corporate-issued devices, which typically have far fewer protections in place to block threats.
Given the numbers of employees working from home due to COVID-19 and the increase in threats targeting those workers, now is the time to be stepping up training and to make sure employees are working in a secure environment. TitanHQ can help you better protect employees and the devices they use to work from home, but you should also ensure that cybersecurity training is reinforced.
Cybercriminals are taking advantage of the 2019 Novel Coronavirus pandemic and are exploiting fear to spread malware and steal data. These tactics many not be new, but these campaigns pose a significant threat in the current climate of global fear and worry.
People are naturally worried about contracting COVID-19 and will be concerned about the wellbeing of their friends and family members. Many people crave new information to help avoid them avoid illness and protect their families. If that information arrives in an inbox, email attachments may be opened, and links clicked to malicious websites.
Even when training is provided to employees and they are taught not to respond to unsolicited messages, open email attachments, or click links in emails from unknown senders, mistakes can still be made. During the COVID-19 crisis, stress levels are high, and this can easily lead to decisions being taken that would not normally be made.
Businesses have been forced to allow their employees to work from home, many of whom are now working in a home environment where there are many distractions. Many people do not have home offices where they can quietly work, and a challenging working environment also makes mistakes more likely. Those mistakes can prove very costly.
Phishing campaigns are being conducted targeting home workers as they are seen as low-hanging fruit and an easy way to gain access to business networks to install malware, ransomware, and steal sensitive data. Several campaigns have been detected that offer important advice on the 2019 novel coronavirus that impersonate authorities on disease control and prevention such as the U.S. Centers for Disease Control and Prevention (CDC), U.S. Department of Health and Human Services, UK National Health Service, and the World Health Organization (WHO). The phishing campaigns are credible, claim to offer important advice, and are likely to be opened by many individuals. These campaigns seek remote access credentials and distribute malware.
Coronavirus maps that display the number of cases per country are being used on many websites, including a legitimate COVID-19 case tracking map on Johns Hopkins University website. One campaign has been detected that uses a carbon copy map and urges users to download a desktop application that allows them to track new cases. The application installs the information-stealing AZORult Trojan. As the COVID-19 crisis has deepened, these phishing and malspam campaigns have increased significantly.
With more people working from home and self-isolating, the risk of malware and phishing attacks has increased significantly. It is therefore important for businesses to make sure that they are properly protected and manage risk. During this difficult time, it is important to provide security awareness training to staff to keep them aware of the threat of cyberattacks and to help them identify malicious messages. Phishing simulation exercises are a useful way of assessing risk and identifying individuals that require further training.
It is also important to implement additional control measure to block attacks at source. There are two main attack vectors being used to target remote workers: Email and the web. Due to the high risk of mistakes by employees it is essential for businesses to have an effective email security solution in place.
The key to improving email security is defense in depth. Layered defenses will greatly improve resilience to phishing and malware attacks. If you are using Office 365 and have yet to augment protection with a third-party email security solution, now is the ideal time. One 2019 study showed that Office 365 protections only block around 75% of phishing attempts. Given the increase in phishing volume, a great many malicious emails will land in inboxes unless protection is improved.
The more time people spend online, the greater the risk. With many workers housebound and self-isolating, online time has increased considerably. Unsurprisingly, the of number of malicious domains being used to distribute malware has increased and drive-by malware attacks have spiked. With corporate laptops being used at home, steps should be taken to limit what employees can do on those laptops. Blocking access to ‘risky’ websites such those distributing pirated TV shows and movies will help to reduce the risk of a malware download, along with controls to prevent the downloading of risky file times such as software installers and executable files.
A web filtering solution will allow you to control the sites that remote employees can access on their corporate laptops and prevent malicious websites from being visited. A cloud-based web filtering solution is the ideal choice as it can be easily implemented to protect all remote workers, without causing any latency issues.
TitanHQ can help you protect your telecommuting workers from email and web-based threats. SpamTitan is a powerful email security solution that compliments Office 365 anti-spam and anti-phishing controls and enhances protection against phishing, spear phishing, and zero-day malware. WebTitan is a cloud-based DNS filtering solution that is simple to implement that allows you to carefully control the online activities of remote employees and block drive-by malware downloads and other web-based threats.
Both solutions can be implemented in a matter of minutes and will greatly improve protection against web and email-based threats. For further information, to book a product demonstration, or to register for a free trial, contact TitanHQ today.
Phishing attacks are increasing and malware is a growing threat. A DNS filter adds an important level of protection to block these attacks. In this post we explain why.
The Growing Threat from Malware and Phishing Attacks
There are various methods used to deliver malware, but email remains one of the most common methods of distributing malware, either through malicious attachments or hyperlinks in emails that direct users to websites where malware is downloaded. The latter is a popular method of malware delivery as there is an increased chance that the hyperlink will not be detected as malicious by an email security solution. Various tactics are used to mask these URLs from email security solutions, such as adding the hyperlink to an attached file such as a PDF.
The Emotet Trojan is one of the most prevalent threats and also one of the most dangerous. Emotet is primarily spread via email through a combination of attachments and malicious URLs. The Trojan is an information stealer capable of spreading across networks to infect other vulnerable devices. Removing the malware is problematic, as there are usually multiple devices infected. As soon as the malware is removed from one device, others on the network re-infect the cleaned machine. Emotet is also a malware downloader. Once all valuable information has been obtained post-infection, other malware variants such as the TrickBot Trojan and RYUK ransomware are downloaded. All devices infected with Emotet are added to the botnet. An analysis by the SpamHaus project revealed around 6,000 malicious URLs are emitted from infected devices, which act as compromise vectors.
An advanced spam filter will ensure that the majority of malicious emails are blocked, but it is important not to totally rely on a spam filter alone to block email-based malware and phishing attacks. The key to a strong defense is to implement layered defenses. With overlapping layers of security, if one layer fails to block a threat, another is in place to provide protection. One of the most important additional protections against phishing attacks and email-based malware is a web filter.
Why a Web Filter is so Important
Phishing attacks have an email and web-based component. The email contains the lure and a hyperlink is included that directs the recipient to a webpage hosting a phishing kit. When the user visits the website credentials and other sensitive information is harvested. A spam filter will block most of these phishing emails and a web filter provides protection against emails that are not blocked, as well as protecting against accidental navigation to malicious websites through malvertising or general web browsing.
A web filter is a form of content control that prevents network users from visiting known malicious websites. When a network user attempts to visit a malicious website, rather than connecting to the site, they are directed to a block page. That block page informs the user that they have attempted to visit a prohibited website which, in this case is a phishing page or website hosting malware. It could equally be a website that violates an organization’s internet usage policies. A web filter therefore serves as an additional, and important, layer of security to block phishing attacks and malware and ransomware downloads.
Web Filtering Options
There are different web filtering options available. Appliance-based web filters were once the go-to solution, but cloud-based filtering is now much more common, more cost effective for most organizations, and easier to implement and maintain.
Appliance-based solutions are not scalable. Once capacity has been reached, another appliance must be purchased. Software-based web filters, which are usually deployed as a virtual appliance on existing hardware, are a good choice but the most popular web filtering solutions are cloud-based. With cloud-based web filters, all filtering takes place in the cloud on the service provider’s hardware. Cloud-based filters are highly scalable. If capacity is increased, additional licenses just need to be purchased which takes seconds.
DNS Filtering is the Most Flexible Web Filtering Choice
The most popular, flexible, and scalable solution is a DNS filter. When a user makes a request to visit a website, such as by clicking a hyperlink or navigating to a website through their browser, a set of procedures must be followed to display the content.
One of the first steps is to send a query to the DNS server. The DNS server matches an easy to remember domain name – google.com for instance – with an IP address that allows the site to be found. A DNS filter works at this stage of the process and will block attempts to visit prohibited websites or malicious sites before any content is downloaded. Modern DNS filters do not just block content at the domain level. They also block content at the URL and page level. This means that a page on Medium.com could be blocked, while other content on the site is allowed. This means filtering controls are very granular and there is less potential for overblocking of web content.

Today there is an increasingly mobile workforce. Workers are able to travel and stay connected to the office and many employees are allowed to work remotely for at least some part of the week. While workers are in the office, security is not a problem for IT departments. Workers connect to the internal network, be that a wired or wireless network, and thanks to the protection of the firewall, their devices and the network are protected. The problem comes when workers move outside the protection of that firewall. Here IT departments struggle to ensure the same level of protection.
When workers are travelling for work or are between the home and the office, they often connect to public Wi-Fi hotspots. Connecting to those hotspots introduces risks. While connected, sensitive information could potentially be disclosed which could be intercepted. Malware could also be inadvertently downloaded. When a connection is made to the work network, that malware could easily be transferred.
Connecting to untrusted Wi-Fi networks is a major risk. These could be legitimate Wi-Fi services provided on public transport, in coffee shops, or city-wide Wi-Fi networks. While these networks may be safe, there is no telling who may be connected to that network. These Wi-Fi networks are often not monitored, and cybersecurity protections may be poor.
There are several possible attack scenarios where an individual could perform malicious acts on users of the Wi-Fi network. One of the biggest risks is a man-in-the-middle attack. In this scenario, a Wi-Fi user will be connected to the network and will believe that they are securely accessing the internet, their email, or even the work network, when the reality is that their connection is anything but secure.
A hacker could be listening in and could obtain information from that connection. Through ARP poisoning, a hacker could trick the Wi-Fi gateway and the user’s device into connecting, and traffic would be routed through the hacker’s device where it is intercepted. An attacker could also create an evil twin hotspot. Here a rogue hotspot is created that closely mimics the genuine hotspot. A Wi-Fi user may mistakenly connect to the evil twin thinking they are connected to the legitimate hotspot. Since the evil twin is operated by the attacker, any information disclosed while connected can be intercepted.
Remote workers must be told never to connect to a Wi-Fi network unless they do so through a VPN than encrypts their data. Employees may forget to connect to their VPN, and if weak passwords are used, even if they are encrypted they could be cracked relatively easily, but with a VPN and password policies, risk will be reduced to a reasonable level.
Wi-Fi networks tend not to have the same protections as corporate networks, so there may be little restrictions on the types of website that can be accessed while connected. To protect remote workers, a DNS filter such as WebTitan should be used.
A DNS filter performs content control at the DNS lookup stage when a user attempts to access the internet. When a web address is entered in the browser, the DNS server looks up the fully qualified domain name (FQDN) and matches it with the IP address of the website. The browser is provided with the IP address and the server is contacted and the content is downloaded. With a DNS filter, before any content is downloaded, it is subject to certain rules. For instance, category-based filtering could be used to prevent adult content from being accessed. An attempt would be blocked before any content is downloaded. Importantly for security, the DNS filter would prevent the user from visiting any known malicious website. A phishing site for instance or a site known to harbor malware. With a cloud-based DNS filtering service, all filtering takes place in the cloud and there is no latency regardless of where the individual is located. DNS filtering protects workers on corporate networks as well as remote workers.
A further control that is useful is an email filtering solution, such as SpamTitan, that incorporates Domain-Based Message Authentication, Reporting, and Conformance (DMARC).
In the event of a user’s email credentials being obtained in a man-in-the-middle attack via a rogue Wi-Fi hotspot, their email account could be accessed by the attacker. Since legitimate credentials are being used, this would not generate any alerts and the attacker could peruse the email account in their own time. If the account is used to send phishing messages, as they often are, DMARC will prevent those messages from being delivered and will alert the company to the issue.
The DMARC element of the spam filter checks the sender’s IP address to make sure it matches the IP on the DNS servers for the sender’s organization to make sure they match. If the IP is not authorized to send messages from that domain, the messages will be rejected or quarantined, and the company would be alerted to the phishing attack. The same is true for spoofing of email addresses.
SpamTitan also includes dual anti-virus engines to identify malware sent via email and sandboxing to help catch previously unknown malware variants that have yet to have their signatures uploaded to AV engines. Any malware sent via email will also be quarantined to keep inboxes free of threats.

The increase in cyberattacks on law firms has highlighted a need for greater security protections, especially to protect against phishing, malware, and ransomware.
According to a recent Law.com report, more than 100 law firms are known to have experienced cyberattacks in the past five years: Cyberattacks that have resulted in hackers gaining access to sensitive information and, in many cases, employee, attorney, and client information.
Investigations such as this are likely to uncover just a small percentage of successful cyberattacks, as many are resolved quietly and are not reported. Many law firms will be keen to keep a cyberattack private due to the potential damage it could do to a firm’s reputation. The reputation of a law firm is everything.
As Law.com explained, there are different data breach reporting requirements in different states. If there is no legal requirement to report the data breaches, they will not be reported. That means that only if reportable information has potentially been compromised will the breach be reported to regulators or made public. It is therefore not possible to tell how many successful cyberattacks on law firms have occurred. However, there has been a steady rise in reported cyberattacks on law firms, as is the case with attacks on other industry sectors. Law.com’s figures are likely to be just the tip of the iceberg.
From the perspective of cybercriminals, law firms are a very attractive target. The types of information stored on clients is incredibly valuable and can be used for extortion. Information on mergers and takeovers and other sensitive corporate data can be used to gain a competitive advantage. Cybercriminals are also well aware that if they can deploy ransomware and encrypt client files, there is a higher than average probability that the ransom will be quietly paid.
Based on the information that has been made public about law firm data breaches, one of the main ways that law firms are attacked is via email. Many of the data breaches started with a response to a phishing or spear phishing email. Phishing allows cybercriminals to bypass even sophisticated cybersecurity protections as it targets a well-known weakness: Employees.
Employees can be trained to be more security aware and be taught how to recognize potential phishing emails, but phishers are conducting ever more sophisticated campaigns and every employee will make a mistake from time to time. That mistake could be all that it takes to compromise a computer, server, or a large part of a network.
One firm contacted for the report explained that it had implemented advanced cybersecurity protections that were undone with a phishing email. The digital security measures it had in place greatly restricted the harm caused, and there was no evidence that the attacker had accessed sensitive information, but the attack did succeed.
In response, the law firm implemented more advanced security protocols, implemented a more aggressive spam filter, multi-factor authentication was used more widely, and it revised its policies and procedures and training. Had those measures been implemented in advance, it may have been possible to block the attack.
The response was to implement more layered defenses, which are critical for blocking modern cyberattacks. Overlapping layers of security ensure that if one measure fails, others are in place to prevent an attack from succeeding.
This is an area where TitanHQ can help. TitanHQ has developed cybersecurity solutions that can fit seamlessly into existing security stacks and provide extra layers of security to block the most common attack vectors. TitanHQ’s email and web security solutions – SpamTitan and WebTitan – provide advanced protection without compromising usability.
Since many clients prefer to communicate via email, it is important for all incoming attachments to be analyzed for malicious code. Extensive checks are performed on all incoming (and outgoing) emails, with SpamTitan able to block not only known malware but also zero-day threats. SpamTitan also includes DMARC email authentication to block email impersonation attacks and sandbox to analyze suspicious files and identify malicious or suspicious activity.
WebTitan provides protection from web-based threats. Most malware is now delivered via the internet, so a web security solution is essential. WebTitan is a DNS filtering solution that protects against all known malicious sites. It is constantly updated in real time through threat intelligence services to ensure maximum protection. The solution provides advanced protection against drive-by downloads and malicious redirects to exploit kits and other malicious sites and provides and important additional layer of security to protect against phishing attacks.
Law firms will no doubt prefer to host their cybersecurity solutions within their own environments or private clouds, which TitanHQ will happily accommodate.

The Spelevo exploit kit is being used to deliver Maze ransomware to unsuspecting internet users via a vulnerability in Adobe Flash Player.
The Spelevo exploit kit has been used to deliver a variety of malicious payloads since it was first detected in early 2019. Initially it was used to silently download the GootKit Trojan, and latterly the Dridex and IceD banking Trojans. Now the threat actors behind Maze ransomware have joined forces with the EK developers to deliver their malicious payload.
Spelevo has previously been loaded onto a compromised business-to-business contact website to target business users, although the latest campaign uses ad network traffic to send users to a fake cryptocurrency website, where they are then redirected to a web page hosting the exploit kit.
The Flash Vulnerability – CVE-2018-15982 – is then exploited in the browser to silently download and execute the ransomware payload. If that download occurs, the user’s files will be encrypted. There is currently no free decryptor for Maze ransomware. Recovery will depend on restoring files from backups – provided they too have not also been encrypted – or the user will face permanent file loss if they do not pay the ransom demand. The ransom doubles if payment is not made within a week.
Exploit kits used to be one of the main ways that malware was distributed, although they fell out of favor with cybercriminals who found alternate, more profitable ways to earn money. The threat never disappeared but exploit kit activity dropped to a tiny fraction of the level seen a few years ago when Angler exploit kit activity was at its peak. However, over the past year or so, exploit kit activity has been increasing. Today, there are several active exploit kits that are being used to deliver a variety of malware and ransomware payloads.
Exploit kits will only work if they have been loaded with an exploit for a vulnerability that has not been patched on a user’s device. Prompt patching will ensure that even if a user lands on a web page hosting an exploit kit, no malware download will take place. However, many businesses are slow to apply patches and it can be several months before vulnerabilities are corrected.
One of the best defenses against exploit kits is a DNS filter. A DNS filter is a control mechanism used to prevent users from visiting malicious websites. With a DNS filter in place, websites known to host malware or malicious code are blocked at the DNS lookup stage, before any content is downloaded. If a user attempts to visit a known malicious web page, they will be directed to a block screen instead.
Web filters can also be used to prevent ‘risky’ file types from being downloaded, such as .exe, .scr, or .js files. In addition to blocking malware downloads, a DNS filter can be used by businesses to enforce their acceptable internet usage policies and prevent employees from accessing productivity-draining websites and adult content.
A web filter is an important part of layered defenses against malware and other internet-based attacks such as phishing. TitanHQ’s DNS filter, WebTitan, is used by thousands of businesses and managed service providers to protect against web-based threats. WebTitan blocks more than 60,000 new malware sites every day and provides businesses and MSPs with real-time protection against the full range of web-based threats.
WebTitan can be deployed in minutes, is updated automatically, highly scalable, and costs as little as 90 cents per user per month. The productivity gains alone from using the solution mean it more than pays for itself, let alone the savings from preventing phishing attacks and costly malware downloads and data breaches.
