Upgrade a Dumb Shell to a Full PTY

2026-08-06 bash Red Team

Turn a raw reverse shell into a fully interactive TTY — job control, arrow keys, tab-complete, clear — via the classic python-pty + stty dance.

bash

# spawn a PTY inside the dumb shell
python3 -c 'import pty; pty.spawn("/bin/bash")'

# background it: Ctrl+Z, then fix the local terminal and pull it back
stty raw -echo; fg

# re-set a sane terminal so clear/less/vim behave
export TERM=xterm
