Unable to fine tune their decryptor, the threat actors behind theBabuk ransomwarehave changed their business model, and are no longer encrypting their victim’s data, according tocybersecurityresearchers.
While it initially attackedWindows machines, theransomwarehad added a cross-platform binary that allowed it to targetLinuxmachines as well as VMware ESXi-powered virtual machines (VM).
However, the researchers observed that Babuk’s decryptor had numerous issues, which meant the files they encrypted weren’t always recoverable, even by their own decryptor.

“Ultimately, the difficulties faced by the Babuk developers in creating ESXi ransomware may have led to a change in business model, from encryption to data theft and extortion,” reason the researchers in ablog post.
Forced change
McAfeeAdvanced Threat Research (ATR) team has been tracking the relatively new Babuk ransomware, which hastargeted at least five major businessesin 2021.
According to the researchers, the ransomware is written in theopen sourceGo programming language, which enables the threat actors to have a single codebase that can be compiled under differentoperating systems.
In theirtechnical analysisof the Babulk ransomware, the researchers unravel its poorly designed decryptor, which they believe is the main reason behind the threat actor switching strategies.

The researchers claim that Babuk has itself shared its intentions to cease its ransomware operations and move to a different business model built around data exfiltration, in its website on the dark web.
Moving from a pure encryption, on to a double-extortion scheme, the researchers conclude that “it is interesting to see threat actors now moving towards a scheme where their sole source of pressure to extort victims is the exfiltration of sensitive data.”
