While many RaaS groups have come and gone in recent years, the LockBit group has been one of the most active. LockBit operates as a ransomware-as-a-service (RaaS) and employs multiple affiliates, causing far more damage than any other ransomware group. As of 2023, it has inflicted 1,029 ransomware victims out of a total of 4,951 ransomware victims, and is aggressive enough to rank first in the number of victims among RaaS groups, at about 20%.the LockBit group has continued to grow their arsenal (which they refer to as a collection): LockBit Red, a 2.0 version of the original LockBit ransomware they developed in June 2021; LockBit Black, which cribbed code from the BlackMatter ransomware in June 2022; and the Conti-based LockBit Green, released this year… How far is the group willing to go to quote code from other ransomware? And then there’s the rumored Babuk. As you can see, we’ve been tracking the LockBit group since its inception.
