Can anyone test my *SMALLEST* SSHD backdoor?

- Survives updates.
- Does not use ~/.ssh/authorized_keys or PAM modules.
- Does not create any new file.

Just SSHD trickery.

@thc, there's a very obvious problem: you're assuming the presence of systemctl.

@lp0_on_fire it will work fine without systemctl. Any way to restart the sshd will work. either by waiting for a reboot or send a SIGTERM.
