Super SSH

  • Description: Using a Secure Shell (SSH) is going to be pretty important.
  • Difficulty: Easy

🔎 Solution​

The goal of this challenge is to demonstrate how to establish an SSH connection to a remote machine. To do this, you can use the following command syntax:

ssh -p <port-number> <username>@<host-address>

When prompted with a fingerprint verification (host authenticity), type yes to continue the connection. Then, enter the correct password when asked. If everything is done correctly, you will successfully establish an SSH session with the target machine - and the flag will be waiting for you upon login.
For example:

┌──(kali㉿kali)-[~/Desktop/drop-in]
└─$ ssh -p 63903 ctf-player@titan.picoctf.net
The authenticity of host '[titan.picoctf.net]:63903 ([3.139.174.234]:63903)' can't be established.
ED25519 key fingerprint is SHA256:4S9EbTSSRZm32I+cdM5TyzthpQryv5kudRP9PIKT7XQ.
This key is not known by any other names.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
