According to some twitter threads published by cybersecurity researchers vx-underground and MalwareHunterTeam, the major ransomware operation LockBit has created encryptors specifically targeting MacOS for the first time.


These encryptors were discovered by cybersecurity researchers on Virustotal and include one called ‘locker_Apple_M1_64’, which targets newer Macs running Apple Silicon.

However, the encryptor appears to be a test and was not intended to be used in live cyber attacks. It is possible that more advanced and optimised encryptors for MacOS and other CPU architectures may appear in the future, so all computer users, including Mac owners, should practice good online security habits to protect themselves.
