VERY ROUGH PROOF OF CONCEPT Work in progress.
Current status: Regularly being broken by me trying to stuff multiple shellcodes into neural networks.
Evolutionary Neural Network Encoder of Shenanigans
This proof of concept program is to explore the use of neuroevolution as a method for encoding shellcode. The encoder uses genetic algorithms to evolve a neural network that will output the desired shellcode at runtime.
Lots of code borrowed from: https://github.com/hoodoer/NEAT_Thesis

The encoder uses genetic algorithms to evolve neural networks that output the shell code on demand. The shellcode to be encoded into the neural networks is included in the "encodedOutput.h" file (not a great name).
You can generate one of these header files from raw shellcode binaries using: https://github.com/hoodoer/shellcodeEncryptor
Just skip the encryption options, it'll output a header file with your shellcode.
This is most definitely a work in progress, but the initial demo works, popping a meterpreter shell in Windows from shellcode output by the neural network
Good overview of the technique can be seen at my CackalackyCon talk:
