THC-Hydra Tool will work in 4 modes:

  • One username & one password
  • User list & One password
  • One username & Password list
  • User list & Password list

Hydra has Various Options:

  • Target – Settings of various target options
  • Passwords – Specify password options & wordlists
  • Tuning – Specify how fast should hydra work. Other timing options are also available.
  • Specific – For testing on specific targets like a domain, https proxy, etc.
  • Start – Start/Stop & shows the output.

Step 1:

Find the Hydra from Kali by searching xHydra.

Here we are setting our Target IP “”(set your Remote Target) In the Target area.

we are using SSH authentication for communicating to remote Target “”

Target: “”  Protocol : SSH

Bottom of the tool we can see the command line which automatically Create when we set out settings in the GUI of THC-Hydra

Step 2:

we Perform a wordlist attack by using a wordlist containing the most common passwords to break into the root account. you can add an “n” number of passwords to your word list.

In the Passwords area, we set our username as “root” and specified our wordlist.txt location in the password list box(/root/password/txt).

Kali Linux comes with built-in word lists.

Search them using the command: locate *.lst in the terminal.

command: locate *.lst

Step 3:

In the Tuning area, we set the number of tasks that we are going to perform.

I set 1 task for the Attack.

you can set the proxy as No Proxy.

Step 4:

we can go ahead and trigger the start attachment by Clicking the start button.

you can see clearly  the terminal command line at the bottom of the tool which is about the target IP, a protocol that we used, and wordlist of dictionary list  (password.txt)

Finally, e have got the result about our target system login ID and password

  • Login ID: root
