Hack Passwords With Cain & Abel - Ultimate Tutorial


In this post i will show you how to crack  local password with cain and abel 

First download cain and abel from "http://www.oxid.it/cain.html" and install it on your system.

Make sure that you have disabled the antivirus/firewall running on your system before installing and throughout this process.

The most effective tecnique  used here is  Brute-Force

Brute-Force - As this techniques takes more time to complete, the attacker prefer this technique  only when there is a hope that the password contain same type of characters or may be two. i.e only loweralpha, only alpha, only numeric or may be loweralpha-numeric, also it should contain less than 7 characters. Otherwise it takes more time to crack password, which may be the mixture of all types of characters along with special symbols.
The step-by-step explaination for this technique is given below-

1) Open the tool "Cain and Abel"   


2) Go into the category "Cracker"      it displays all sub-categories under "Cracker"

     in left panel.

3) Select "LM & NTLM Hashes" from left panel and then click on      symbol, you will be greeted by   

    a window as shown.

4) Check "import hashes from local system" and then click "Next". This shows all the active accounts on local system like administrator, guest, etc. along with LM and NT hashed values of their respective passwords, as shown below.


5) Right clicking on a
ny username shows all available options using which we can crack it's password.


6) Here we select "Brute-Force Attack" and then "NTLM Hashes", since windows uses NTLM hashes  

    to store local users' passwords.

7) You will be greeted by a window where you can modify properties for brute-force attack such as 

     password length, character set, etc.

8) Click on "Start" button.

9) On completion it will reveal the exact password.
