To find out about different new gamers obtain the 2023 Ransomware Report right here.
3AM Ransomware
A newly found ransomware pressure named 3AM has emerged, however its utilization has been restricted thus far. In 2023 they’ve solely managed to affect 20+ organizations (largely within the USA). Nevertheless, they’re gaining notoriety because of a ransomware affiliate who tried to deploy LockBit on a goal’s community switching to 3AM when LockBit was blocked.
New ransomware households seem often, and most disappear simply as shortly or by no means handle to achieve important traction. Nevertheless, the truth that 3AM was used as a fallback by a LockBit affiliate means that it could be of curiosity to attackers and might be seen once more sooner or later.
