Bypass SSH /bin/false Shell

Is it possible to get a remote shell with ssh, if it is set to /bin/false instead of bash? is there a way to exploit ssh port forwarding (not DOSing)? If you're already on the system via another user: sudo -u username /bin/bash Also, you could backdoor /bin/false A good read: https://commandline.ninja/2012/05/06/binfalse-sbinnologin-and-ssh/ Thanks, Adam, very interesting link!
