You should adapt it to your needs (payload and parameters). It is an improvement on my original Nimcrypt project, with the main improvements being the use of direct syscalls and the ability to load regular PE files as well as raw shellcode. At a high level the loader re-implements HellsGate but uses indirect instead of direct syscalls to make the Callstack look less suspcicious.
