Back in the day when I knew a group of hackers one of the most useful tools
was some code known as SaranWrap. With it you would run something
like ./saranwrap fungame.exe virusortrojan.exe. The trojan would then be wrapped inside of the "plastic wrap" ... so the outer layer would be the game and the inner layer would be the payload. It worked very well and was not detectable by any malware suites at the time. Some of these wrappers are to have polymorphic code that hides the payload, having it in an altered
encrypted form so there may be 16 trillion permutations and the virus payload either not being detectable or only being detectable by rare anti-viruses
that can only detect a small portion of the permutations.
