Reverse shells & TTY upgrade

When it applies

You have command execution and want an interactive shell on an authorized target. Pick the payload that matches what's installed on the victim, catch it on a listener, then upgrade it so editors, job control, and tab-completion work. $LHOST/$LPORT below are your attacker IP and port.

Why it works

A reverse shell makes the victim connect out to you (beating inbound firewalls); a bind shell listens on the victim (use only when you can't receive connections). The victim's shell inherits no PTY, so it's "dumb" until you attach one — the upgrade step gives you a full terminal.
