Forward Shell
A forward shell is something I'll use much less frequently than a reverse shell. It come in handy when you have RCE but can't get a reverse shell, providing a persistent shell (persistent as in between commands, not across machine reboots) with the potential to get a full interactive terminal to run commands like su, sudo, and ssh.
This video builds on the exploration of pipes from the mkfifo reverse shell video, here: • Exploring mkfifo / nc Reverse Shell
