The holiday season is here!
During a year with such major ups and downs, it’s a nice break, right? Well, cyber attackers won’t be taking a break, unfortunately. In fact, they’ll want to take full advantage of unprepared IT teams.

Meanwhile, here’s this month’s ransomware roundup, along with some interesting new trends.
Ransomware: Printers, Facebook Ads, and TurboTax
Ransomware creators continue to find new and unusual ways to attack companies and pressure them to pay.
They understand that those companies often want to suppress information about the nature of an attack until the situation is fully understood.
The Egregor ransomware gang capitalizes on this fear with their new technique: spewing ransom notes from all available printers within the organization. While we might initially see this as annoying and wasteful, during the Egregor attack on Cencosud, the attack was broadcast to more than just their 140,000 employees.
As one of the largest retail companies in Latin America, their embarrassment was compounded when the ransom note began printing on their register receipt printers inside their stores.
The Ragnar Locker gang took a different approach to promote their attack on Compari Group, an Italian liquor company.
In addition to the $15 million ransom to restores systems, the Ragnar Locker group stole 2 TB of data and created Facebook ads to add more public pressure to the company. This novel campaign was caught and stopped by Facebook after being seen by 7,000 people.
Ragnar didn’t buy the ads directly. Instead, they hacked the account for Hodson Event Entertainment, an Illinois-based disc jockey, and purchased the ads through that company’s account.
The DarkSide ransomware operation created a distributed data storage system to prevent authorities from recapturing data or blocking ISPs that host stolen data.
Meanwhile, the Mount Locker ransomware gang chose to specialize and has developed a ransomware that focuses on tax data.
Their software specifically targets TurboTax’s .tax file extensions for both encryption and data extraction.
Recent Ransomware Victims & Outcomes
Ransomware attacks have become so common that attacks on a county website in North Carolina, Public Library systems in Pennsylvania, and a multinational Biotech company didn’t even make the headlines.
Instead, the highest profile attack was suffered by Capcom, the Japanese videogame company behind the enormously popular Megaman, Street Fighter, and Resident Evil franchises.
Capcom decided not to pay the Ragnar Locker ransom. Instead, the company allowed the attackers to publish confidential corporate documents, customer’s personal information, and the information of 14,000 employees.
How many organizations could survive such a breach?
Capcom could face lawsuits from employees, and will likely face regulatory fines, if the leaked data contained information from citizens in the EU (GDPR violations), California, or New York (individual state privacy protection laws).
Of course, data leaks are only part of the problem. Office furniture giant Steelcase suffered a two week global shutdown after a Ryuk ransomware attack and was forced to file formal announcements with the SEC.
Managed.com, a website hosting company, was forced — by a REvil ransomware attack — to shut down the websites for all of their customers. The attack led some customers to switch hosting providers.
Meanwhile, the cold storage company, Americold, similarly shut down their operations to deal with a ransomware attack.
The concern about the Americold attack are particularly troublesome, as their facilities may become part of the refrigerated supply chain for COVID-19 vaccines. Ransomware attackers will certainly focus on the vaccine supply chain to put even more pressure on organizations to pay.
Make It Difficult For Ransomware Gangs
Law enforcement discourages the payment of ransoms.
We have often mentioned basic preventative measures, such as multifactor authentication and network segmentation. However, there are other preventative measures that can help:
- Review Group Policy preferences to ensure previously stored passwords have been purged
- Review admin processes to make sure passwords do not linger in Notepad, scripts or batch files
- Require users to use fresh passwords
- Restrict the use of Remote Desktop Protocol (RDP) to static IP addresses, RDgateway protected access, or two-factor authentication protected access
- Disable Server Message Block protocol version 1 (SMBv1)
- Patch systems to prevent privilege escalation
- Employ strong email filtering and train users about phishing to limit exposure
- Network and user monitoring to catch attacks
