usage: darkarmour.py [-h] [-f FILE] -e ENCRYPT [-S SHELLCODE] [-b] [-d] [-u]
                     [-j] [-r] [-s] [-k KEY] [-l LOOP] [-o OUTFILE]

optional arguments:
  -h, --help            show this help message and exit
  -f FILE, --file FILE  file to crypt, assumed as binary if not told otherwise
  -e ENCRYPT, --encrypt ENCRYPT
                        encryption algorithm to use (xor)
  -S SHELLCODE, --shellcode SHELLCODE
                        file contating the shellcode, needs to be in the
                        'msfvenom -f raw' style format
  -b, --binary          provide if file is a binary exe
  -d, --dll             use reflective dll injection to execute the binary
                        inside another process
  -u, --upx             pack the executable with upx
  -j, --jmp             use jmp based pe loader
  -r, --runpe           use runpe to load pe
  -s, --source          provide if the file is c source code
  -k KEY, --key KEY     key to encrypt with, randomly generated if not
                        supplied
  -l LOOP, --loop LOOP  number of levels of encryption
  -o OUTFILE, --outfile OUTFILE
                        name of outfile, if not provided then random filename
                        is assigned

Usage

  • Generate an undetectable version of a pe executable

    ./darkarmour.py -f bins/meter.exe --encrypt xor --jmp -o bins/legit.exe --loop 5

Installation

It uses the python stdlib so no need to worry about any python dependencies, so the only issue you could come accoss are binary dependencies. The required binarys are: i686-w64-mingw32-g++, i686-w64-mingw32-gcc and upx (probly osslsigncode soon as well). These can all be installed via apt.

sudo apt install mingw-w64-tools mingw-w64-common g++-mingw-w64 gcc-mingw-w64 upx-ucl osslsigncode

TODO

  • Intergrate into PowerUp
  • Optional signing of binarys
  • Load pe image over a socket so not stored inside the binary
