Stabilize Reverse shell

use CTRL + C

# In reverse shell
python -c 'import pty; pty.spawn("/bin/bash")'
Ctrl-Z
# In OS
stty raw -echo
fg

There's three popular ways I use to stabilize a reverse shell;

• Python, as mentioned above.

• riwrap, which prepends to a netcat shell for additional terminal features.

• Socat, which is a step above netcat but must be manually transferred over and launched on the target machine.
