The Week in Ransomware - September 30th 2022 - Emerging from the Shadows​

Hand reaching out from smoke

This week's news primarily revolves around LockBit, BlackMatter, and the rising enterprise-targeting Royal ransomware operation.
As expected, threat actors now use the leaked LockBit 3.0 ransomware builder for their ransomware operations. For example, the Bl00Dy Ransomware Gang, who previously used Babuk and Conti encryptors, has now switched to a LockBit 3.0 encryptor in an attack on a Ukrainian business.
Researchers also reported that TargetCompany ransomware affiliates are now targeting publicly exposed Microsoft SQL servers.
Another interesting research is the prediction that ransomware gangs may move away from encrypting altogether and switch to pure data exfiltration and file deletion to cut out the ransomware developer. This idea stems from a new file deletion/corruption feature in a data theft tool used by a BlackMatter affiliate.
Finally, this week we learned about Royal Ransomware, which has been quietly working from the shadows since February but has, more recently, ramped up attacks.
Contributors and those who provided new ransomware information and stories this week include: @Seifreed, @serghei, @VK_Intel, @billtoulas, @DanielGallagher, @jorntvdw, @PolarToffee, @BleepinComputer, @fwosar, @struppigel, @demonslay335, @LawrenceAbrams, @Ionut_Ilascu, @FourOctets, @malwrhunterteam, @malwareforme, @swascan, @y_advintel, @AdvIntel, @angel11VR, @InsideStairwell, @aejleslie, @Cyderes, @ahnlab, and @pcrisk.

Analyzing Bloody Ransomware

Today (09/25/22) very limited information was received for analysis from one of the Ukrainian victims of the Bl00dy Ransomware Gang . Unfortunately, from the files provided, it is not possible to establish the vector of interference, the time frame of the attack, and which operations were automated and which were conducted interactively, however, the information turned out to be quite sufficient to reconstruct the attack scheme .

I just got back to work after a week in the mountains. My company has been getting slammed with some pretty sophisticated phishing attacks. No ransomeware attacks yet but they have been hammering away. Fortunately one of our products is disaster prevention/recovery so we have all the proper hardware and procedures in place. It is a pain and expensive to do so though.
