I don't know if it's entirely unexpected, because Messenger has been used for spreading viruses in the past. It's way more vulnerable than emails because people check it on an hourly, and maybe even by minute details. Either way, internet security rules still apply. Never download executables or zipped files unless you're absolutely sure they're safe. Bots sending files are pretty easy to spot anyway.
It's funny how hackers seem to be shifting from ransomware to mining viruses though. Crypto is truly starting to become relevant, albeit in a bad way in this case.
I mean people are going to be following the money, which isn't rare and is kinda supposed to happen -- sadly when it comes to hacking this is the sort of thing that's going to happen but yeah.
This is something that we're gonna have to educate people about, cause we don't want the name for crypto being tarnished becauseof some super greedy fucks who are trying to make a buck but in the meantime killing the chance for crypto to help.
