A few days ago, international law enforcement authorities scored a decisive blow against Lockbit. However, according to a comment from Chester Wisniewski, Director, Global Field CTO at Sophos, some of their infrastructure is still online, which likely indicates that some of the Lockbit cybercriminal group have not yet been caught.
The chance of them joining other groups or forming a new group would not be a surprise. Sophos X-Ops is now publishing a report about the recently known security vulnerability in the remote management and monitoring solution ScreenConnect. The detailed analysis also finds a connection with Lockbit.
Christopher Butt, Sophos X-Ops Principal Researcher at Sophos, said: “We have analyzed several attacks in the last 48 hours that exploited the ScreenConnect vulnerability. The most notable was a piece of malware created using the Lockbit 2022 ransomware builder tool leaked in 3. It may not be from the actual Lockbit developers. But we also discovered Remote Access Trojans (RATS), info and password stealers, and other ransomware.
ScreenConnect in sight
“All of this shows that many different attackers are targeting ScreenConnect,” said Christopher Budd, director of Sophos X-Ops Threat Research. “Anyone using ScreenConnect should take steps to immediately isolate vulnerable servers and clients, patch them, and check for signs of compromise. Sophos offers comprehensive guidance and threat hunting materials from Sophos X-Ops to help you. We are continuing our investigation and will make updates as necessary.”
The malware activity of the last 48 hours and the use of Lockbit technology could confirm Chester Wisniewski's suspicion that parts of the Lockbit group are still active or that Lockbit malware technology is still being used by other groups.
