I know that Linux is more secure than Windows and normally doesn’t need an antivirus, but know myself I’m gonna end up downloading something at some point from somewhere on the internet, and it would be good to be prepared. So, which antivirus would you recommend for Linux (Mint specifically) just to double up on security?
Brodie Robertson made a video about malware which pretends to be a pdf but is actually just an executable with a
.pdffile extension. So if you double click it, you get pwnd. I think some desktop environments ask you for confirmation before running such thing but I would not count on it.So we even have an example of Linux specific malware.
It shouldn’t even be able to run it, because the x permission bit is missing. As far as I know binaries can’t include icons on linux, so it would look different too.
Nope, the permission bit is preserved if you share the pdf in an archive like zip. The “looks different” won’t help. There is always at least a single user who accidentally falls for a trap, which looks like an obvious trap to others.
