LockBit ransomware for Mac - coming soon?

In the last couple of days it has become clear that the notorious LockBit ransomware gang has been exploring creating what could one day become a big headache for users of Mac computers.

Security researchers have found that someone uploaded a ZIP archive to VirusTotal containing different flavours of LockBit’s ransomware encryptors… including a version designed to run on Macs with an Apple Silicon M1 chip.

The good news: Mac security expert Patrick Wardle says the current sample is unsigned (meaning it won’t run easily on macOS), crashes, and can’t currently be considered a threat.
