How to Hydra Brute force to Recover Password


Hey! w0rms lthis is Viv and you're reading Hydra Brute force tutorial, well its one of the most used technique but the only thing I don't like about Brute force attack is We've to make a Guess, well lemme tell you guys that there is little difference between Dictionary Attack and Brute Force Attack but while using Hydra it becomes harder to differentiate. And yeah (Know Hacking but No Hacking).

What is Brute Force Attack?

A password attack that continue to try different passwords. For example, a brute-force attack may have a dictionary of all words or a listing of commonly used passwords. To gain access to an account using a brute-force attack, a program tries all available words it has to gain access to the account. Another type of brute-force attack is a program that runs through all letters or letters and numbers until it gets a match.

How to Hydra Brute Force?

Requirements in order to perform this technique
  • Backtrack 4, 5 or Kali Linux with Internet connection
  • Password.txt file (That contains Possible passwords)
To demonstrate this tutorial I've created a fake mail account as a victim for eg (hackerseven5@gmail.com)  and it's password is '521478963' a phone number.  Now I'm an attacker and my task is to find out correct password for the mail account. The other fact is I don't know the exact password but i do know possibilities, In these cases we'll use Brute Force Attack using Hydra tool.

Your first task is to create a possible password list text file. Save it on Desktop.

Now you'll see Hydra has started but first we've to define Target information like port, protocol etc. so this is how we'll force an application to match correct password. 

Note : All websites have different Port and Protocol before target-ting, make sure you've all the info. you can either google it or find our yourself using different techniques.

For this Ethical tutorial I'm using Gmail as target. Fill the blanks as i did in below image. [Single Target = smtp.gmail.com Port =  465 Protocol = smtp Tick =   Use SSl, Be Verbose, Show Attempts]
