Cracking passwords in Kali Linux using Hydra

Hydra is a very fast connection bruteforer that supports many different services.
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.
For brute forcing Hydra needs a list of passwords. There are lots of password lists available out there. In this example we are going to use the default password list provided with John the Ripper which is another password cracking tool. Other password lists are available online, simply Google it.
Disclaimer – Our tutorials are designed to aid aspiring pen testers/security enthusiasts in learning new skills, we only recommend that you test this tutorial on a system that belongs to YOU. We do not accept responsibility for anyone who thinks it’s a good idea to try to use this to attempt to hack systems that do not belong to you
Under Kali Linux is preinstalled , and install it on mini version just use the deposit .
apt-get install hydra-gtk
==using Hydra==
You will find hydra in the menu ” Applications -> Kali Linux -> Passwords Attacks -> Online Attacks -> hydra- gtk “
Normally you should see this window .
For example, we will perform a XXX account bruteforce to draw your attention to the importance of using a password “strong” ( special characters, uppercase letters, numbers … )
In the “Target” tab, fill in as below :
Be Verbose box used to display the detail of the execution of the attack .
Note that you can also submit a list of addresses ( Target List)
Then go to the tab ” Passwords ”
Fill in the email address to test ( or an address list) and the path to your dictionary
Know that there is an archive containing a wordlist in the directory “/ usr / share / wordlist /”. To use it you must first extract
The Tuning tab used to configure the number of concurrent task and the timeout and the use of a proxy.
The use of an HTTP proxy is configured in the Specific tab
Skip to the “Start” tab
Now click on “start” at the bottom left to start the attack. If you have chosen a password can like the one I chose for the tutorial , here is what happen to you :
I used my own email address for the attack which I had previously changed the password so that you can easily include the dictionary. Use of this software is designed to test the robustness of its own password and not to attack a place without the consent of its owner. The law severely punished any attempt to attack without authorization imprisonment and a strong almond.
