Keeping up-to-date with cybersecurity news can help protect organizations from online threats such as malware downloads and phishing campaigns. By being aware of type of threats that exist, how they operate, and what damage they can do, organizations can take precautions against the threats, educate their employees to be aware of online security, and strengthen their online defenses.
The most effective way of preventing attacks by cybercriminals is to stop Internet users from receiving emails containing phishing links or visiting websites that harbor viruses. This can be achieved with an email filter and an Internet content filter – both solutions having mechanisms in place to protect organizations and ensure they are not featured in future in our cybersecurity news section.
Ransomware attacks slowed in 2018 but the malicious file-encrypting malware is back with a vengeance. Ransomware attacks on educational institutions have soared this year, and as the attackers are well aware, these attacks can be extremely profitable.
There have been 182 reported ransomware attacks so far this year and 26.9% of those attacks have been on school districts and higher education institutions. The increase has seen education become the second most targeted sector behind municipalities (38.5%) but well ahead of healthcare organizations (14.8%).
The reason why the number of ransomware attacks on educational institutions, healthcare, and municipalities is so high compared to other sectors is because attacks are relatively easy to perform and there is a higher than average chance that the ransoms will be paid.
Attacks on municipalities mean they can’t access computer systems, and essential services grind to a halt. Police departments can’t access criminal records, courts have to be shut down, and payments for utilities cannot be taken. If hospitals can’t access patient data, appointments have to be cancelled out of safety concerns. In education, teachers cannot record grades and student records cannot be accessed. Administration functions grind to a halt and a huge backlog of work builds up.
Some of the recent ransomware attacks on school districts have seen schools forced to send students home. Monroe-Woodbury Central School District in New York had to delay the start of the school year due to its ransomware attack. If students need to be sent home, there is often backlash from parents – Not only because their children are not getting their education, but childcare then needs to be arranged.
The costs of these attacks are considerable for all concerned. Each day without access to systems costs schools, universities, municipalities, and hospitals a considerable amount of money. Downtime is by far the biggest cost of these attacks. Far greater than any ransom payment.
It is no surprise that even when ransom demands are for tens or hundreds of thousands of dollars, they are often paid. The cost of continued losses as a result of the attacks makes paying the ransom the most logical solution from a financial perspective. However, paying the ransom sends a message to other cybercriminals that these attacks can be extremely profitable, and the attacks increase.
The huge cost of attacks has seen educational institutions take out insurance policies, which typically pay the ransom in the event of an attack. While this is preferable financially for the schools, it ensures that the attackers get their pay day. Some studies have suggested that attackers are choosing targets based on whether they hold insurance, although the jury is out on the extent to which that is the case.
In total, 49 school districts and around 500 K-12 schools have been affected by ransomware attacks this year. While the ransomware attacks on school districts have been spread across the United States, schools in Connecticut have been hit particularly hard. 7 districts have been attacked, in which there are 104 schools.
Prevention of these attacks is key but securing systems and ensuring all vulnerabilities are identified and corrected can be a challenge, especially with the limited budgets and resources of most schools. Cybersecurity solutions need to be chosen wisely to get the maximum protection for the least cost.
A good place to start is by addressing the most common attack vectors, which for ransomware is Remote Desktop Protocol and email-based attacks.
Remote Desktop Protocol should be disabled if it is not required. If that is not possible, connection should only be possible through a VPN. Rate limiting should also be set to block access after a number of failed login attempts to protect against brute force password-guessing attacks.
Email security also needs to be improved. Massive spam campaigns are being conducted to distribute the Emotet banking Trojan, which serves as a downloader for Ryuk ransomware and others. Embedded hyperlinks in emails direct end users to sites where they are encouraged to download files that harbor malware, or to exploit kits where ransomware is silently downloaded.
Advanced spam filters should be deployed that incorporate sandboxing. This allows potentially suspicious email attachments to be checked for malicious activity in a safe environment. DMARC email authentication is also important as it is one of the best defenses against email impersonation attacks. SpamTitan now incorporates both of these measures.
A DNS based content filtering solution is also beneficial as an additional protection against malware downloads and phishing attacks. Not only can the content filter be used to ensure compliance with CIPA, it will prevent end users from visiting malicious websites where ransomware is downloaded.
Email attacks usually require some user interaction, which provides another opportunity to block the attacks. By educating all staff and students on the risks, they can be prepared for when malicious emails arrive in their inboxes and will be conditioned how to respond.
It is often the case that breached entities only implement these measures after an attack has occurred to prevent any further attacks from succeeding. By taking a more proactive approach and implementing these additional security measures now, costly, disruptive attacks can be avoided.
For more information on ransomware defenses such as email and DNS filters for educational institutions, give the TitanHQ team a call today. You are likely to find out that these security measures are far cheaper than you think… and naturally a great deal less expensive than having to deal with an attack.
2017 was a bad year for ransomware attacks, but as 2018 progressed it was starting to look like the file-encrypting malware was being abandoned by cybercriminals in favor of more lucrative forms of attack. Between 2017 and 2018 there was a 30% fall in the number of people who encountered ransomware compared to the previous year, and the number of new ransomware variants continued to decline throughout 2018; however, now, that trend has been reversed.
2019 has seen a sharp increase in attacks. Figures from Malwarebytes indicate there was a 195% increase in ransomware attacks in Q1, 2019 and that increase has continued in Q2. A new report from Kaspersky Lab has shown that not only are attacks continuing to increase, the number of new ransomware variants being used in these attacks is also increasing sharply.
Kaspersky Lab identified 16,017 new ransomware modifications in Q2, 2019, which is more than twice the number of new ransomware modifications detected in Q2, 2018. In addition to updates to existing ransomware variants, Q2, 2019 saw 8 brand new malware families detected.
Kaspersky Lab tracked 230,000 ransomware attacks in Q2, which represents a 46% increase from this time last year. Far from ransomware dying a slow death, as some reports in 2018 suggested, ransomware is back and is unlikely to go away any time soon.
Not only are attacks increasing in frequency, ransom demands have increased sharply. Ransom demands of hundreds of thousands of dollars are now the norm. Two Florida cities paid a combined total of $1 million for the keys to unlock files encrypted by ransomware. Jackson County in Georgia paid $400,000 for the keys to unlock the encryption that crippled its court system, and recently, a massive ransomware attack that impacted 22 towns and cities in Texas saw a ransom demand of $2.5 million issued.
Earlier this year, the developers of GandCrab ransomware shut down their popular ransomware-as-a service offering. They claimed to have made so much money from attacks that they have now taken early retirement. Despite GandCrab ransomware being one of the most widely used ransomware variants for the past 18 months, the shut down has not been accompanied with a reduction in attacks. They continue to increase, as other ransomware-as-a-service offerings such as Sodinokibi have taken its place.
Ransomware attacks are increasing because they are profitable, and as long as that remains the case, ransomware is here to stay. Businesses are getting better at backing up their data but recovering files from backups and restoring entire systems is a difficult, time-consuming, and expensive task. When major attacks are experienced, such as those in Texas, recovering systems and files from backups is a gargantuan task.
Attackers realize this and set their ransom demands accordingly. A $400,000 ransom demand represents a sizable loss, but it is a fraction of the cost of recovering files from backups. Consequently, these sizable ransoms are often paid, which only encourage further attacks. It is for this reason that the FBI recommends never paying a ransom, but for many businesses it is the only option they have.
Businesses naturally need to develop plans for recovering from an attack to avert disaster in the event of ransomware being installed on their network, but they must also invest in new tools to thwart attacks. At the current rate that attacks are increasing, those tools need to be implemented soon, and that is an area where TitanHQ can help.

A new phishing campaign has been detected which uses Microsoft Office 365 voicemail notifications as a lure to get users to open a malicious HTML file attached to the email.
The phishing emails are very realistic. The emails include the Microsoft and Office 365 logos, use the Microsoft color scheme, and Microsoft contact information. The messages inform the recipient that they have received a new voicemail message. The caller’s number and length of the voicemail message is included, along with the time and date of the message. In order to access that message, the user is required to open a HTML file attached to the email.
Many phishing campaigns use Word documents or Excel spreadsheets containing malicious macros or embedded hyperlinks that direct users to a phishing web page where credentials are harvested. Through security awareness training employees are told to look out for thee commonly used file types. HTML files are likely to be familiar to employees, but since these file types are not often used in phishing campaigns, employees may believe the attached file to be benign, when that is definitely not the case.
The HTML file uses meta refresh to redirect the user from the local HTML file to a phishing page hosted on the Internet. That phishing page contains a highly realistic spoofed voicemail management page where users are required to enter their Office 365 credentials to access the message. Doing so hands those credentials to the attacker.
Cybercriminals are constantly coming up with new ways to trick employees into clicking links in emails or opening malicious attachments. Keeping the workforce up to date on these threats is important. If employees are aware of the types of scam emails, they are likely to receive they will be more likely to correctly identify an email as malicious if it arrives in their inbox.
Keeping the workforce 100% up to date on the latest scams will not be possible as new scams and lures are constantly being developed. It is therefore important to ensure that you have an advanced spam filtering solution in place that can block these messages to ensure they never test employees.
SpamTitan incorporates DMARC to block email impersonation attacks, dual antivirus engines to identify known malware, and a sandbox where suspicious attachments can be executed safely and studied for malicious actions. In addition, a range of checks are performed to assess the content of messages and embedded hyperlinks for any malicious actions.
With SpamTitan in place, businesses will be able to block more than 99.97% of spam and phishing emails, and 100% of known malware.
If you want to improve protections against phishing attacks and ensure fewer malicious messages reach your Office 365 inboxes, give the TitanHQ team a call to find out more about SpamTitan email security and other measures you can take to improve your security posture and block these sophisticated phishing attacks.
The FBI’s Internet Crime Complaint Center (IC3) has issued a warning about the increasing number of phishing websites using HTTPS.
The green padlock next to a URL once gave an impression of security. Now it is a false sense of security for many internet users.
HTTPS or Hyper Text Transfer Protocol Secure to give it its full name, indicates the website holds a valid certificate from a trusted third-party. That certificate confirms that the website is secure and any data transmitted between the browser and the website will be encrypted to prevent interception in transit.
The public has been taught to look for the green padlock and HTTPS before entering card details or other sensitive information. However, the padlock does not mean that the website being visited is genuine. It only means any information transmitted is secured in transit between the browser and the website.
If you are buying a pair of shoes from Amazon, all well and good. If you are on a website controlled by a cybercriminal, HTTPS only means that the cybercriminal will be the only person stealing your data.
Cybercriminals create realistic phishing webpages that imitate well-known brands such as Microsoft and Google to obtain login credentials or banks to obtain banking information. These phishing pages can be set up on dedicated phishing websites or phishing kits can be added to previously compromised websites. Traffic is then generated to those webpages with an email phishing campaign.
If one of the links in the email is clicked, a user will be directed to a website that requests some information. If the website starts with HTTPS and displays the green padlock, the user may mistakenly believe the site is genuine and that it is safe to disclose sensitive information.
The IC3 alert was intended to raise awareness of the threat from HTTPS phishing and make the public aware of the true meaning of the green padlock and never to trust a website because it starts with HTTPS.
Businesses should take note and make sure they include HTTPS phishing in their security awareness training programs to raise awareness of the threat with employees.
A web filter can greatly reduce the risk of HTTPS phishing attacks, provided the web filter has the capability to decrypt, scan, and re-encrypt HTTPS traffic.
WebTitan provides real-time protection against web-based attacks and uses a constantly updated database of 3 million known malicious sites to block attempts to visit phishing websites. WebTitan is capable of SSL inspection and can inspect HTTPS traffic, block specific applications within a webpage, and display alerts or block sites with fake https certificates.
If you want to improve protection against web-based attacks, contact the TitanHQ team today for more information about WebTitan.
While it is good news the GandCrab ransomware operation has been shut down, ransomware attacks are on the rise and a new threat has been detected: Buran ransomware.
Buran ransomware lacks some of the common features of more successful ransomware strains. The ransomware does not make any attempt to hide its activity and it doesn’t attempt to hamper recover by deleting Windows shadow copies. However, it is capable of encrypting a wide range of file types and there is currently no free decryptor available to unlock encrypted files.
Buran ransomware is being spread via the RIG exploit kit, with traffic to that exploit kit generated using a malvertising campaign. Malicious adverts have been injected into legitimate ad networks and are being displayed on a range of different websites. The malvertising campaign was identified by security researcher nao_sec.
The malvertising campaign directs web browsers to a domain hosting RIG, which attempts to exploit several vulnerabilities in Internet Explorer. If an unpatched vulnerability exists, Buran ransomware will be downloaded and executed.
An analysis of the malware suggests it is a new variant of Vega ransomware that was previously used in a campaign in Russia.
While Buran ransomware may not be a long-term successor to GandCrab ransomware, there are many threat actors moving to fill the void. Sodinokibi ransomware attacks are increasing and the ransomware developers are also using a malvertising campaign on the PopCash ad network to deliver traffic to domains hosting the RIG exploit kit.
Exploit kits can only download malware if they have been loaded with an exploit for a vulnerability that has not been patched on a visitor’s computer. The primary defense against these attacks is to ensure that all Windows security updates are applied promptly, along with updates and patches for plugins and other browsers.
There is invariably a delay between a patch being issued and all devices being updated. To provide protection until patches are applied, and to protect against zero-day exploits, a web filtering solution is recommended. A web filter can be used to control the websites that can be visited by employees and can block access to known malicious websites to prevent attacks on vulnerable computers.

Earlier this month, the FBI Internet Crime Complaint Center (IC3) released its annual Internet Crime Report, which highlights the most common attack trends and the extent of financial losses based on victims’ reports of internet crime. The report highlighted the seriousness of the threat of Business Email Compromise (BEC) attacks, which resulted in losses of more than $1.2 billion in 2018 – More than twice the losses to BEC attacks that were reported in 2017.
2019 is likely to see losses increase further still as the BEC attacks are continuing at pace. Last week, almost coinciding with the release of the report, Scott County Schools in Kentucky announced that it was the victim of a major BEC attack that resulted in a loss of $3.7 million.
The school was notified by a vendor that a recent invoice was outstanding. Further investigation revealed payment had been made, just not to the vendor in question. An email had been received that appeared to be from the vendor, which included forged documents and details of a bank account that was controlled by the scammer.
The FBI was contacted, and attempts are being made to recover the funds, although since the payment was made two weeks previously, it is unclear whether it will be possible to recover the money.
A few days later, news broke of another major BEC scam, this time on a church. St. Ambrose Catholic Parish in Brunswick, Ohio, was a victim of a BEC attack that resulted in the fraudulent transfer of $1.75 million from the Church’s renovation fund. The scam was a virtual carbon copy of the Scott County Schools BEC attack.
The church was contacted by its contractor after not having had invoices paid for two months. That was news to the church, which believed that payments had been made on time. The funds had left the church account but had been directed elsewhere. The investigation into the BEC attack revealed hackers had gained access to the church’s email system and altered the contractor’s bank and wire transfer instructions.
These are just two recent examples of major losses to BEC attacks. Many other million-dollar and multi-million-dollar losses have been reported over the past 12 months.
With potential profits in the upper hundreds of thousands or millions of dollars, it is no surprise that organized criminal gangs are turning to business email compromise scams. The scams are easier to pull off than many other crimes and the potential profits are considerably higher.
Business email compromise scams involve the impersonation of an individual or company. The scams are often conducted via email and usually include a request for a wire transfer. The scams require some research to identify a company to impersonate, but in many cases that is not particularly difficult. It would not be difficult, for example, to identify a contractor that is conducting a major renovation. The company’s banners are likely to be clearly visible around the building where the work is being completed.
Impersonating a company is far from challenging. It is child’s play to spoof an email and make it appear to have come from another domain. The scams are even more convincing if an email account is compromised. Then the email will come from a genuine account.
Gaining access to an email account requires a carefully crafted phishing email that directs the recipient to a phishing webpage that collects login credentials – such as Office 365 credentials. A single phishing email could start the scam in motion.
These BEC attacks show how critical it is for businesses to have an advanced anti-spam solution in place to prevent the initial phishing attack from succeeding and to implement multi-factor authentication for email accounts to make it harder for stolen credentials to be used to gain access to corporate email accounts.

Reputation loss after a cyberattack can have a major impact on businesses. While large companies may be able to absorb the loss of customers that results, for small to medium businesses, reputation damage and loss of customers can prove devastating.
Cybersecurity consultants and computer forensics firms can be hired to find out how an attack occurred, and new solutions can be implemented to plug the holes through which access to the network was gained. Regaining the trust of customers can be much harder to recover from. Once trust in a brand is lost, some customers will leave and never return.
When personal data has been exposed or stolen, customers feel betrayed. Company privacy policies may not be read, but customers believe that any company that collects their personal data has a responsibility to protect it. A data breach is seen as a breach of the company’s responsibility to keep personal data private and secure, and many customers will take their business elsewhere after such a privacy violation.
Reputation loss after a cyberattack can also make it hard to find new customers. Once information about a breach has been made public, it can be enough to see potential customers avoid a brand.
Extent of Reputation Loss After a Cyberattack
Radware recently conducted a survey to investigate the cost of cyberattacks on businesses. The study revealed 43% of companies that took part in the study said they had experienced negative customer experiences and reputation loss as a result of a successful cyberattack.
Previous studies suggest that as many as one third of customers will stop doing business with a company that has experienced a data breach. A study by Gemalto paints an even bleaker picture. In a global survey of 10,000 individuals, 70% claimed they would stop doing business with a company that had experienced a data breach.
The cyberattack on the telecoms company TalkTalk in 2015 – which cost the firm an estimated £77 million – caused uproar online. Customers turned to social media networks to express their rage about loss of service and the theft of their personal data. The company’s reputation took a massive hit as a result of the attack, not helped by interviews with the hackers who explained how easy it was. The firm claimed it lost around 101,000 customers as a result of the incident. Research from Kantar Worldpanel ComTech suggests 7% of its broadband customers – around 300,000 people – left the firm for another provider.
With such potential losses, it is no surprise that the Marsh and Microsoft Global Cyber Risk Perception Survey in 2018 found that reputation loss after a cyberattack was the biggest concern of companies. 59% of respondents rated it as a major concern.
Steps can naturally be taken to limit customer turnover, repair reputations, and win back customer trust, but repairing damage to a brand and winning back customers can be a long uphill struggle.
Given the high probability of a cyberattack and the potential repercussions, increased investment in cybersecurity defenses to prevent breaches should be given serious consideration.
It is not possible to prevent all cyberattacks, but it is possible to implement security solutions to protect against the most common attack vectors – email and malicious websites – and that is an area where TitanHQ can help.
The Fallout exploit kit, a toolkit used to silently deliver ransomware and malware to vulnerable devices, was first identified in September 2018. Between September and December, the toolkit was used to exploit vulnerabilities and deliver GandCrab ransomware and other malicious payloads. Towards the end of the year, the vulnerabilities most commonly exploited were a remote code execution vulnerability in the Windows VBScript engine (CVE-2018-8174) and the use-after-free vulnerability in Adobe Flash Player (CVE-2018-4878).
Around December 27, 2018, Fallout exploit kit activity stopped, but only for a few days. Now the exploit kit is back, and several updates have been made including the addition of HTTPS support, a new landing page format, and PowerShell-based malware downloads. A new exploit has also been added for a zero-day use-after-free Adobe Flash player vulnerability (CVE-2018-15982) which was patched on December 5, 2018: A vulnerability also exploited by the Underminer exploit kit.
The Fallout exploit kit is primarily delivered via malvertising campaigns – malicious adverts on third-party ad networks that are served on a variety of legitimate websites. The adverts redirect users to the exploit kit, which probes for vulnerabilities and exploits them to silently deliver malware or ransomware. The updated version of the Fallout exploit kit is delivering the latest version of GandCrab ransomware, for which there is no free decryptor. In addition to GandCrab ransomware, the Fallout exploit kit is delivering ServHelper, AZORult, TinyNuke, Dridex and Smokebot malware.
The malvertising campaigns used to generate traffic to the exploit kit include TrafficShop, Popcash, RevenueHits, and HookAds. The latter is primarily used on high-traffic adult websites that are visited millions of times a month. Users are redirected to a decoy adult site that contains the exploit kit and would be unaware that anything untoward has happened. If there is an unpatched vulnerability for which fallout has an exploit, the ransomware or malware payload will be silently downloaded.
Exploit kit activity is now much lower than in 2016 when EKs were extensively used to deliver malware, but the latest updates show EKs are still a threat and that they are regularly being updated with the latest exploits.
Exploit kits can only deliver malware if unpatched vulnerabilities are present, so prompt patching is strongly recommended. Users also need to visit the sites hosting the exploit kit. Businesses can prevent users from visiting malicious websites using a web filter.
Web filters use blacklists of websites known to host exploit kits are capable of scanning websites for malicious content. They can also prevent third-party ads from being displayed, thus preventing redirects. Since certain categories of website are often used in malvertising campaigns, adult sites and torrents sites for instance, blocking access to those categories of content with a web filter is also recommended.

A Starbucks porn filter will finally be introduced in 2019 to prevent adult content from being accessed by customers hooked up to the coffee shop chain’s free WiFi network.
It has taken some time for the Starbucks porn filter to be applied. In 2016, the coffee shop chain agreed to implement a WiFi filtering solution following a campaign from the internet safety advocacy group Enough is Enough, but two years on and a Starbucks porn filter has only been applied in the UK.
Businesses Pressured to Implement WiFi Filters to Block Porn
Enough is Enough launched its Porn Free WiFi campaign – now renamed the SAFE WiFi campaign – to pressure businesses that offer free WiFi to customers to apply WiFi filters to restrict access to adult content. In 2016, more than 50,000 petitions were sent to the CEO’s of Starbucks and McDonalds urging them to apply WiFi filters and take the lead in restricting access to pornography and child porn on their WiFi networks.
After petitioning McDonald’s, the global restaurant chain took prompt action and rolled out a WiFi filter across its 14,000 restaurants. However, Starbucks has been slow to take action. Following the McDonalds announcement in 2016, Starbucks agreed to roll out a WiFi filter once it had determined how to restrict access to unacceptable content without involuntarily blocking unintended content. Until the Starbucks porn filter was applied, the coffee shop chain said it would reserve the right to stop any behavior that negatively affected the customer experience, including activities on its free WiFi network.
The apparent lack of action prompted Enough is Enough to turn up the heat on Starbucks. On November 26, 2018, Enough is Enough president and CEO, Donna Rice Hughes, issued a fresh call for a Starbucks porn filter to be implemented and for the coffee chain to follow through in its 2016 promise. Rice Hughes also called for the public to sign a new petition calling for the Starbucks porn filter to finally be put in place.
Starbucks Porn Filter to Be Applied in All Locations in 2019
Starbucks has responded to Enough is Enough, via Business Insider, confirming that it has been testing a variety of WiFi filtering solutions and has identified one that meets its needs. The Starbucks porn filter will be rolled out across all its cafes in 2019.
All businesses that offer free WiFi to their customers have a responsibility to ensure that their networks cannot be abused and are kept ‘family-friendly.’ It is inevitable that some individuals will abuse the free access and flaunt policies on acceptable use. A technical solution is therefore required to enforce those policies.
While Enough is Enough is focused on ensuring adult content is blocked, there are other benefits of WiFi filtering. A WiFi filter protects customers from malware downloads and can stop them accessing phishing websites. All manner of egregious and illegal content can be blocked.
WiFi filters can also help businesses conserve bandwidth to make sure that all customers can access the Internet and enjoy reasonable speeds.
WebTitan Cloud for WiFi – The Easy Way to Start Filtering Content on WiFi Networks
TitanHQ has long been an advocate of WiFi filtering for public WiFi hotspots and has developed WebTitan Cloud for WiFi to allow businesses to easily block access to unacceptable and illegal web content on WiFi networks.
WebTitan Cloud for WiFi allows businesses to carefully control the content that can be accessed over WiFi without involuntarily blocking unintended content. Being 100% cloud based, no hardware purchases are required and no software downloads are necessary.
The solution offers businesses advanced web filtering capabilities through an easy to use intuitive user interface. No IT consultants are required to implement and run the solution. It can be set up and operated by individuals that have little to no technical knowhow.
The solution is highly scalable and can be used to protect thousands of users, at multiple locations around the globe, all controlled through a single user interface.
If you run a business that offers free WiFi to customers and you have not yet started controlling the activities that can take place over your WiFi network, contact TitanHQ today for further information on WebTitan Cloud for WiFi.
Managed Service Providers (MSPs) that want to start offering WiFi filtering to their clients can join the TitanHQ Alliance. All TitanHQ solutions have been developed to meet the needs of MSPs and make it easy for them to add new security capabilities to their service stacks.
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.

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.

The CloudFlare IPFS gateway has only recently been launched, but it is already being used by phishers to host malicious content.Cloudflare IPFS gateway phishing attacks are likely to have a high success rate, as some of the checks performed by end users to confirm the legitimacy of domains will not raise red flags.
The IPFS gateway is a P2P system that allows files to be shared easily throughout an organization and accessed through a web browser. Content is distributed to different nodes throughout the networked systems. The system can be used for creating distributed websites, and CloudFlare has made this process easier by offering free SSL certificates and allowing domains to be easily connected to IPFS.
If phishers host their phishing forms on CloudFlare IPFS, they benefit from CloudFlare’s SSL certificate. Since the phishing page will start with cloudflare-ipfs.com, this adds legitimacy. The CloudFlare-owned domain is more likely to be trusted than domains owned by phishers.
When CloudFlare IPFS Gateway phishing forms are encountered, visitors will be advised that the webpage is secure, the site starts with HTTPS, and a green padlock will be displayed. If the visitor takes the time to check certificate information of the web page, they will find it has been issued to CloudFlare-IPFS.com by CloudFlare Inc., and the certificate is valid. The browser will not display any warning and CloudFlare IPFS Gateway phishing content will therefore seem legitimate.
At least one threat actor is using the CloudFlare IPFS Gateway for phishing and is hosting forms that claim to be standard login pages for Office 365, DocuSign, Azure AD, and other cloud-based services, complete with appropriate logos.
If a visitor completes the form information, their credentials will be forwarded to the operator of a known phishing domain – searchurl.bid – and the user will be displayed a document about business models, strategy and innovation. This may also not raise a red flag.
The CloudFlare IPFS Gateway phishing strategy is similar to that used on Azure Blob storage, which also take advantage of legitimate SSL certificates. In that case the certificate is issued by Microsoft.
It is becoming increasingly important for phishers to use HTTPS for hosting phishing content. As more businesses transition from HTTP to HTTPS, and browsers such as Chrome now display warnings to users about insecure sites, phishers have similarly had to make the change to HTTPS. Both CloudFlare IPFS Gateway and Azure Blog storage offer an easy way to do this.
In both cases, links to the malicious forms are distributed through spam email. One of the most common ways to do this is to include an email attachment that contains a button which must be clicked in order to download content. The user is advised that the content of the file is secured, and that professional email login credentials must be entered in order to view the content. The document may be an invoice, purchase order, or a scanned document that needs to be reviewed.
The increase in use of cloud platforms to host phishing content makes it more important than ever for organizations to implement advanced phishing defenses. A powerful spam filter such as SpamTitan should be used to block the initial emails and prevent them from being delivered to end users’ inboxes. These phishing tactics should also be covered in security awareness training to raise awareness of the threat and to alert users that SSL certificates do not necessarily mean the content of a web page is legitimate. Web filtering solutions are also essential for blocking access to known malicious web pages, should a user visit a malicious link.
A suspected Ryuk ransomware attack on Recipe Unlimited, a network of some 1,400 restaurants in Canada and North America, has forced the chain to shutdown computers and temporarily close the doors of some of its restaurants while IT teams deal with the attack.
Recipe Unlimited, formerly known as Cara Operations, operates pubs and restaurants under many names, including Harvey’s, Swiss Chalet, Kelseys, Milestones, Montana’s, East Side Mario’s, Bier Markt, Prime Pubs, and the Landing Group of Restaurants. All of the above pub and restaurant brands have been affected by the Recipe Unlimited ransomware attack.
While only a small number of restaurants were forced to close, the IT outage caused widespread problems, preventing the restaurants that remained open from taking card payments from customers and using register systems to process orders.
While it was initially unclear what caused the outage, a ransomware attack on Recipe Unlimited was later confirmed. An employee of one of the affected restaurants provided CBC News with a copy of the ransom note that had appeared on the desktop of one of the affected computers.
The ransom note is the same used by the threat actors behind Ryuk ransomware. They claim files were encrypted with “military algorithms” which cannot be decrypted without a key that is only held by them. While it is unclear exactly how much the attackers demanded in payment to decrypt files, they did threaten to increase the cost by 0.5 BTC (Approx. $4,000 CAD) per day until contact was made. The Recipe Unlimited ransomware attack is understood to have occurred on September 28. Some restaurants remained closed on October 1.
The ransomware attack on Recipe Unlimited is just one of many such attacks involving Ryuk ransomware. The attackers are understood to have collected more than $640,000 in ransom payments from businesses who have had no alternative other than to pay for the keys to unlock their files. The ransomware attack on Recipe Unlimited did not increase that total, as Recipe Unlimited conducted regular backups and expects to be able to restore all systems and data, although naturally that will take some time.
Ransomware attacks on restaurants, businesses, healthcare providers, and cities are extremely common and can be incredibly costly to resolve. The recent City of Atlanta ransomware attack caused widespread disruption due to the sheer scale of the attack, involving thousands of computers.
The cost of resolving the attack, including making upgrades to its systems, is likely to cost in the region of $17 million, according to estimates from city officials. The Ransomware attack on the Colorado Department of Transportation is expected to cost $1.5 million to resolve.
There is no simple solution that will block ransomware attacks, as many different vectors are used to install the malicious file-encrypting software. Preventing ransomware attacks requires defense in depth and multiple software solutions.
Spam filtering solutions should be used to prevent email delivery of ransomware, web filters can be configured to block assess to malicious websites where ransomware is downloaded, antivirus solutions may detect infections in time to block attacks, and intrusion detection systems and behavioral analytics solutions are useful to rapidly identify an attack in progress and limit the harm caused.
All operating systems and software must be kept fully up to date, strong passwords should be used, and end user must receive training to make them aware of the threat from ransomware. They should be taught security best practices and trained how to identify threats. Naturally, robust backup policies are required to ensure that in the event of disaster, files can be recovered without having to pay the ransom.
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.
There has been a marked rise in HTTPS phishing website detections, phishing attacks are increasing, and the threat of phishing attacks is greater than ever before.
Phishing is the biggest cyber threat that businesses must now deal with. It is the easiest way for cybercriminals to gain access to email accounts for business email compromise scams, steal credentials, and install malware.
The Threat from Phishing is Getting Worse
The Anti-Phishing Working Group – an international coalition of government agencies, law enforcement, trade associations, and security companies – recently published its phishing trends activity report for Q1, 2018. The report shows that the threat from phishing is greater than ever, with more phishing websites detected in March 2018 than at any point in the past year.
In the first half of 2017, there was an average of 48,516 phishing websites detected each month. The figure rose to 79,464 phishing websites detected on average per month in the second half of the year. In the first quarter of 2018, there was an average of 87,568 phishing websites detected, with detections peaking in March when more than 115,000 phishing sites were identified.
The number of unique phishing reports received in Q1, 2018 (262,704) was 12.45% higher than in the final quarter of 2017.
Healthcare Industry Heavily Targeted
In the United States, the Health Insurance Portability and Accountability Act (HIPAA) requires healthcare providers, health insurers, healthcare clearinghouses and business associates of HIPAA-covered entities to report breaches of protected health information within 60 days of the discovery of the breach. The main enforcer of HIPAA compliance, the Department of Health and Human Services’ Office for Civil Rights (OCR), publishes summaries of those breach reports. Those summaries show just how serious the threat from phishing is.
HIPAA-covered entities and business associates have reported 45 email hacking incidents in 2018 – 21.68% of all breaches reported.
Phishers Make the Move to HTTPS
PhishLabs, an anti-phishing vendor that provides a security awareness training and phishing simulation platform, has been tracking HTTPS phishing websites. The company has recently released figures showing there has been a sharp increase in HTTPS phishing websites in the past few months with HTTPS and SSL certificates now popular with phishers.
As businesses make the switch to HTTPS, the phishers have followed. In the final quarter of 2015, a little over 1% of all phishing websites were hosted on HTTPS. By the final quarter of 2016, the percentage had increased to a shade under 5%. By the end of the final quarter of 2017, 31% of phishing sites used HTTPS. The Q1, 2018 figures show HTTPS phishing websites now account for a third of all phishing websites.
HTTPS websites ensure the connection between the browser and the website is encrypted. This offers greater protection for website visitors as information entered on the site – such as credit card numbers – is secure and protected from eavesdropping. However, if the site is controlled by a cybercriminal, HTTPS offers no protection.
The Importance of SSL Inspection
Protecting against phishing attacks and malware downloads via HTTPS websites requires the use of a web filtering solution that performs SSL inspection. If a standard web filtering solution is used that is unable to inspect HTTPS websites, it will not protect employees from visiting malicious websites.
It is certainly possible to block users from accessing all HTTPS websites, which solves the problem of SSL inspection, but with more websites now using HTTPS, many valuable internet resources and essential websites for business could not be accessed.
While many businesses may be reluctant to implement SSL filtering due to the strain it can place on CPUs and the potential for slowing internet speed, TitanHQ has a solution. WebTitan includes HTTPS content filtering as standard to ensure businesses are protected from HTTPS phishing websites and other online threats while ensuring internet speeds are not adversely affected.
You can find out more about how you can protect your business from phishing websites by contacting the TitanHQ sales team and asking about WebTitan.
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.
