According to my last tutorial about generating Rainbow Crack using WinRTGen, now I want to share tutorial about how to Crack Windows Password Using RCrack, Pwdump, and Rainbow Table, and how easy it is..:-). This tutorial usually used to recover your Windows password accidentaly forgot.
7 years ago at the 1st time I learn about IT, my classmate tell me that if you want your password hard to be cracked you should fill it with alpha-numeric and also character and your password should not below 15 chars. Yep that's true 🙂 because if you only have password between 1 – 10 chars (all chars) it will be more easier to crack and the cracker maybe only need 1 or 2 minutes to decrypt your password.
In this Crack Windows Password Using RCrack, Pwdump, and Rainbow Table tutorial, I have one user account "mycomp" as administrator and the password is reveal123, I use only 1 – 10 alphanumeric password characters for the example(it takes long time to generate the table…believe me..:p LoL), but the process is the same for the password more than that, so don't worry about it. Once you know about it, it will be easier on the next step.
1. As usual, at the first time you need to prepare the tools to doing this(rCrack and PwDump), but I've already make it simple to bundle all of the latest application into 1 file and you can download it below(Mediafire.com).
2. Extract all of the application, then create a new folder in drive C:\ rename into "pwdump". Copy the pwdump7.exe and libeay32.dll into it. Extract the rCrack file, then create new folder inside pwdump folder and rename into "rcrack". Copy all the rainbowcrack-1.5-win32.zip contents(without folder) into it.
3. The next step you need to use PwDump7.exe to dump the protected storage containing your password hash inside your Windows Box. See the picture for more details.
– Go to command prompt and go to pwdump directory.
– Execute this command pwdump7.exe > myPassword.txt it means that you will dump your Windows password hash into myPassword.txt.
– In this tutorial I only choose only 1 password to crack, but if you want more than 2 or 3 it's okay the application can crack all of it.
4. The next step we will use rcrack with Rainbow Tables to crack the password. Change your directory to rcrack then execute this script :
rcrack.exe path_to_rainbow_tables -f path_to_password_hash
Voilla, you find the password :-). The time to cracking the password is not too long, but you must wait a long time when you generate the rainbow table :p LoL.
