Is it possible to boot a computer from an USB, get all the information you need (Files or maybe passwords), store them on the USB, shut the computer down and leave like nothing happend? I think this is possible with Kali Linux but is there also an automated process? and is it also possible to put mallware on the computer?
and can this be prevented, for instance disable the other boot options or have some weird antivirus installed on your computer.
I am really curious because the only thing i could find was a USB that acted as a keyboard.
