Russian hacker group Evil Corp has reportedly current its attack techniques to keep away from sanctions prohibiting US corporations from shelling out it a ransom.
The change was noted by menace intelligence agency Mandiant, who not long ago wrote a blog post attributing a series of Lockbit ransomware intrusions to UNC2165, a danger cluster sharing several overlaps with Evil Corp.
UNC2165 was sanctioned by the US Treasury Division in 2019 for working with the Dridex malware to infect hundreds of banks and economical institutions throughout 40 nations and thieving a lot more than $10m.
From a regulatory standpoint, these sanctions effectively prevented targeted organizations from having to pay UNC2165 a ransom to restore obtain to their techniques.
“These sanctions have experienced a immediate affect on threat actor functions, especially as at minimum some organizations involved in ransomware remediation routines, these as negotiation, refuse to aid payments to regarded sanctioned entities,” wrote Mandiant.
“This can ultimately minimize danger actors’ ability to be compensated by victims, which is the most important driver of ransomware operations.”
At the exact time, to hide evidence of the group’s involvement (so that compromised corporations had been extra probably to spend the ransom), Evil Corp/UNC2165 has reportedly changed tactics over the past couple of decades, switching from the WastedLocker to the Hades ransomware.
In accordance to Mandiant, the hacking group would have adjusted strategies at the time once more and began using the ransomware-as-a-support (RaaS) identified as Lockbit from early 2021.
“The adoption of an present ransomware is a normal evolution for UNC2165 to try to obscure their affiliation with Evil Corp,” wrote the danger intelligence firm.
“Using this RaaS would allow UNC2165 to blend in with other affiliate marketers, requiring visibility into previously phases of the attack lifecycle to adequately attribute the exercise, compared to prior operations that may possibly have been attributable based on the use of an distinctive ransomware.”
Mandiant concluded their article by suggesting that the actors behind UNC2165 operations could go on to consider more measures to distance by themselves from the Evil Corp title in the long term.
“We anticipate these actors as well as other people who are sanctioned in the long run to acquire steps these types of as these to obscure their identities in purchase to make sure that it is not a restricting factor to obtaining payments from victims.”
