A script for generating common revshells fast and easy.
Especially nice when in need of PowerShell and Python revshells, which can be a PITA getting correctly formated.

PowerShell revshells​

  • Shows [email protected], above the prompt and working-directory
  • Has a partial AMSI-bypass, making some stuff a bit easier
  • TCP and UDP
  • Windows Powershell and Core Powershell
  • Functions for uploading and downloading files. (Using by sc0tfree)

ngrok support​

  • ngrok can be started/stopped from inside the script
  • payloads will be genereated with the ngrok addresses

Updog support​

  • you can start/stop Updog from inside the script
  • The PowerShell revshells have upload/download function embedded
  • To upload from nix using curl: curl -F path="absolute path for Updog-folder" -F file=filename

To install Shells​

git clone
cd shells
./install.sh
