Cracking SSH password with a known user

In this recipe we will crack SSH passwords with a know username:

  1. Open a terminal window in Kali by clicking the icon. 
  1. Now let's run hydra using our known username and wordlist. You will notice that this does take some time but ultimately you will get the passwords:
hydra -t 4 -l kiddoe -P /usr/share/wordlists/rockyou.txt ssh://192.168.56.104 
Hydra output screen
The -t 4 slows the amount of processes down so it does not overwhelm or trigger protections against some SSL instances.
