Penelope – Advanced shell handler

Penelope is an advanced shell driver whose main purpose is to replace Netcat as the shell receiver when exploiting RCE vulnerabilities. It works on Linux and macOS and the only requirement is Python3. This is a scenario with no third-party dependencies, and hopefully, it will stay that way. …

  1. Auto-upgrade shells to PTY (auto-resize included)

  2. Logging interaction with the targets

  3. Download files from targets

  4. Upload files to targets

  5. Upload preset scripts to targets

  6. Spawn backup shells

  7. Multiple sessions

  8. Multiple listeners

penelope.py 5555              # Listening for reverse shells on 0.0.0.0:5555
penelope.py 5555 -i eth0      # Listening for reverse shells on eth0:5555

penelope.py -c target 3333    # Connect to a bind shell on target:3333

Limitations of Penelope

1. Emojis don’t appear on mate-terminal (parrot OS)

2. Download command: path links are not clickable on the terminal (Kali Linux)

3. The menu commands and PTY authorize operate on the same socket. This could be an advantage but it has a side effect that for example if nano is open on target, then detaching the session and attempt a download, Penelope copes with that by sending Ctrl-Z -> Ctrl-E -> Ctrl-U. Then must run FG to get the process back. Maybe consider spawning an extra socket for controlling the session in the future. However, if before executing a menu command, the target’s terminal is left in a clear state, then there is no problem.
