Hackers use new 3AM ransomware to save failed LockBit attack
2023-09-13 12:29

A new ransomware strain called 3AM has been uncovered after a threat actor used it in an attack that failed to deploy LockBit ransomware on a target network.

Researchers say in a report today that the new malware "Has only been used in a limited fashion" and it was a ransomware affiliate's fallback when defense mechanisms blocked LockBit.

Symantec's Threat Hunter Team, part of Broadcom, says that attacks using 3AM ransomware are rare, saying that they only saw it in a single incident when a ransomware affiliate switched to it because they could not deploy LockBit.

BleepingComputer is aware of a 3AM ransomware attack that occurred in February, around the time the operation appears to have launched, but could not obtain a sample for analysis.

Symantec's Threat Hunter Team says that 3AM is written in Rust and appears to be unrelated to any known ransomware family, making it a completely new malware.

The researchers say that a 3AM ransomware attack is preceded by the use of a "Gpresult" command that dumps the system's policy settings for a specific user.
