As in title. What’s your experience with it? If something isn’t executable, then it has to exploit vulnerability in order to run anything malicious. But does it happen often with mp4, mkv and other files like mp3 or epub?
I assume that if I use updated linux, then I’m mostly safe?
We don’t - but the risk is minuscule compared to windows. The actual chance of finding some working Linux malware in the wild is practically zero.
