Reverse Shell Stabilisation

Below is one example of how to stabilise a reverse-shell.

What are the benefits of a reverse-shell:

  • Makes using text editors like nano or vim possible
  • Allows use of more keyboard keys; cursor arrows, tab etc
  • Common commands like su and ssh require a stable terminal
  • Standard error is more robust at showing you output

I was having trouble with an older method of reverse shell stabilisation; the CTF room I was completing kept having the reverse shell die on me. So after a bit of research, I found a slightly tweaked version of my method on this CTF Bookstore writeup [Thanks Richard]

export TERM=xterm-256color
python3 -c 'import pty;pty.spawn("/bin/bash")'
stty raw -echo;fg

This worked first time.

Amazing work Richard, thanks.
