Last week, SophosLabs showed us a new ransomware sample.
That might not sound particularly newsworthy, given the number of malware variants that show up every day, but this one is more interesting than usual…
…because it’s targeted at Mac users. (No smirking from the Windows tent, please!)
In fact, it was clearly written for the Mac on a Mac by a Mac user, rather than adapted (or ported, to use the jargon term, in the sense of “carried across”) from another operating system.
This ransomware, detected and blocked by Sophos as OSX/Filecode-K and OSX/Filecode-L, was written in the Swift programming language, a relatively recent programming environment that comes from Apple and is primarily aimed at the macOS and iOS platforms.
