I have an old computer that I don't use for anything important or sensitive.
I occasionally download music on this old computer and transfer the mp3 files from a usb onto my primary computer.
These mp3 files come from
download from soundcloud
youtube to mp3
You can literally serach for those exact expressions and find countless sites that will provide this service.
Can these mp3 files that I'm getting from these presumably untrustworthy sites be dangerous in any way? If so, how?
