SSH Brute force by Hydra

on


Hydra: -   Hydra is a parallelized login cracker which supports numerous protocols to attack. It is very fast and flexible, and new modules are easy to add. This tool makes it possible for researchers and security consultants to show how easy it would be to gain unauthorized access to a system remotely.

Syntax:- 
    hydra -l root -P /root/kio1/pass.txt ssh://192.168.32.130 -t 4 -V
  1. hydra              = command/tool name
  2. -l                     = if you wan to give single user ( in above command we have given username "root", no username list). 
    1. if you want to user username list the add  capital -L and mention the list path here.
  3.  -P                   = as explained above we have mentioned password list here so using capital -P and path of the list
    1. if we need to give only one password then we can mention small -p
  4. ssh://<<IP>>  = we are brute forcing ssh so this is the syntax for that. need to mention the IP address on the place of <<IP>>
  5. -t                     = is number of threads we are giving to this task.
  6. -V                    = verbose/verbosity.
