Pico CTF

Super SSH

Description

Using a Secure Shell (SSH) is going to be pretty important.

Can you ssh as ctf-player to titan.picoctf.net at port 51450 to get the flag? You'll also need the password 84b12bae. If asked, accept the fingerprint with yes. If your device doesn't have a shell, you can use: https://webshell.picoctf.org If you're not sure what a shell is, check out our Primer: https://primer.picoctf.com/#_the_shell

Hints

  1. https://linux.die.net/man/1/ssh
  2. You can try logging in 'as' someone with "user"@titan.picoctf.net
  3. How could you specify the port?
  4. Remember, passwords are hidden when typed into the shell
