How to Crack Windows 10, 8 and 7 Password with John the Ripper

August 7th, 2017 by Admin

Forgot the password to your Windows admin account? There are a lot of different reasons why one would want to hack a Windows password. This tutorial will show you how to use John the Ripper to crack Windows 10, 8 and 7 password on your own PC.

Step 1: Extract Hashes from Windows

Security Account Manager (SAM) is a database file in Windows 10/8/7/XP that stores user passwords in encrypted form, which could be located in the following directory:
C:\Windows\system32\config

The first thing we need to do is grab the password hashes from the SAM file. Just download the freeware PwDump7 and unzip it on your local PC.

Open a Command Prompt. Navigate to the folder where you extract the PwDump7 app, and then type the following command:
PwDump7.exe > d:\hash.txt

extract-windows-password-hashes

Once you press Enter, PwDump7 will grab the password hashes from your current system and save it into the file d:\hash.txt.

Step 2: Cracking Passwords with John the Ripper

As you can see the password hashes are still unreadable, and we need to crack them using John the Ripper. John the Ripper is one of the most popular password cracking tools available that can run on Windows, Linux and Mac OS X.

Just download the Windows binaries of John the Ripper, and unzip it.

Open a Command Prompt and change into the directory where John the Ripper is located, then type:
john --format=LM d:\hash.txt

crack-password-with-john-the-ripper

It will start cracking your Windows password. In my example, you can clearly see that John the Ripper has cracked the password within matter of seconds.

Final Words

John the Ripper is probably the world’s best known password cracking tool. But its lack of a GUI interface makes a bit more challenging to use. Don’t use it for illegal purposes.

How to Crack Windows Server 2003 Password?

All you need to do is to create a Live CD which contains password cracking utility on another computer you can login, then bring the Live CD to boot up your server that you need to crack a password on.  It allows you to crack both local administrator password and domain administrator password on your Windows Server 2003. These instructions are written assuming a bootable CD is being used, but are essentially the same for a bootable USB flash drive.

  2. Burn the ISO image on a new CD use your favorite burning software (If you don’t have one, I recommend you use ISO2Disc.) Once the CD is burned successfully, unplug the Live CD from the computer.
  3. Insert the Live CD into your locked computer with a forgotten Windows Server 2003 password. Set the computer BIOS to boot with CD drive as first boot device. After booting from the CD, the computer will load the Windows PE operating system inside the CD drive and open up the Reset Windows Password utility.
  4. Select your Windows SAM registry hive from the drop-down list. The program will perform a complete analysis of the SAM file and display a list of Windows local user accounts inside it. If you’re going to crack the domain admin/user password, click on the “Reset Active Directory Password” option, the program will show you all domain user accounts on your server.
  5. Choose the user account whose password needs to be cracked, and click on “Reset Password” button. It will crack/remove your lost or forgotten password instantly.
  6. Remove the CD and re-boot the system and you should now be able to log on Windows Server 2003 immediately.

The Live CD could also be used to crack lost or forgotten admin/user password on Windows Server 2012/2008/2000. This is probably the most effective, simple piece of software that you have seen around.

How to Hack Windows Password with Free Linux Live CD

May 20th, 2012 by Admin

Forgetting Windows password means losing access to important files and settings on your computer. A password hint can provide clues to help you recall your password. But in most situations, we can’t recognize the importance of password hint and leave it as blank when set a new password. How to hack or recover Windows password so you can regain access to your computer?

In this tutorial we’ll show you how to hack Windows password with a Linux live CD – Ophcrack, which is a freeware that can crack Windows password so you can login without making any changes to your computer.

Step 1: Download Ophcrack and Create A Linux Live CD

The first thing we will need to do is download the CD image from Ophcrack’s website. There are two options to download: XP or Vista. So make sure you grab the right one. The Vista download works with Windows Vista or Windows 7, and the only difference between XP and Vista is the “tables” Ophcrack uses to hack the password.

Once the .iso file is downloaded, burn it to a CD using any CD/DVD burning software you like, such as BurnCDCC or ImgBurn. If you are going to be cracking your password on a computer that doesn’t have a CD drive, such as a netbook, you can also burn the ISO image to a USB flash drive using Universal USB Creator.

Step 2: Hack Windows Password

Boot the computer from the Linux Live CD that you created.  On some computers you may have to go into the BIOS settings to change the boot order or push a key to show the boot menu.

Once the disk is done booting, Ophcrack should start automatically and will begin hacking the passwords for all of the users on your computer.

If you have a complex password it will take a lot longer than simple passwords, and with the free tables your password may never be cracked. Once the hack is done you will see the password in plain text, write it down and reboot the machine to login. If your password isn’t hacked, you can also log in as one of the other users with admin rights and then change your password from within Windows.

With the free tables available you will not be able to hack every password, but the paid tables range from $100 to $1000 so you may be better off just resetting your password with Reset Windows Password utility.
