A fully undetectable payload generator in python. working in 2021.
git clone https://github.com/NiekGevers/fud_payload-generator.git
cd fud_payload-generator
python3 fud_payload-generator.py
When running you need to specify the listening host and port after this you can also try to convert the .ps1 payload to exe with a program like ps2exe (if converting to exe there is a higher change your antivirus will detect it!).
Now you can set up a listener like netcat to recieve your connection.
This script basically takes the payloads from the payloads folders and changes certain things like the lhost and lport to make things easier. You can also add a custom fake msg box.
