A rewritten version of the (Almost) Fully Undetectable EXE I originally made. YOU MUST HAVE MinGW INSTALLED LIKE THE PROCEDURE I'VE SHOWN IN NULL-BYTE http://null-byte.wonderhowto.com/forum/set-up-mingw-kali-using-wine-0159622/
This is a reworked version. Originally, you just pasted in the code. I've turned it into a simple bash script.
