syscall_nimject

using nim to inject shellcode via direct syscalls

Compile generate.nim:

nim c generate.nim

Usage:

generate a raw shellcode using msfvenom or cobalt strile..

generate.exe -f shellcode.bin

this will produce a "main.exe" which is the backdoor, place it whereever you want.

NOTE: Make sure to turn off Defender's Automatic Sample Upload, AND DO NOT UPLOAD TO VIRUS TOTAL.

Special thanks to @ajpc500 for NimlineWhispers <3.

A small note ⚠️ compiling the backdoor with -d:release or -d:danger switches somehow ruins NtWriteVirtualMemory needs more investigation.
