April 22, 2012

If you’ve ever forgotten your password to log in to a computer, you’ll know how annoying it can be. By using Ophcrack Live CD, it can automatically decrypt the HASH file (The encrypted password) from your hard-drive, and give you the password you forgot. This works only for local accounts, not accounts that are on a network, like school user accounts, whose information is on a domain server.

All you need is blank CD and a CD/DVD recorder. You’ll also need internet access and enough free hard disk space to download the ISO image of Ophcrack Live CD, it’s about 450 MB. Follow this step-by-step guide to know how can you create a Ophcrack Live CD and crack your lost or forgotten Windows password with it.

Disclaimer: Do NOT do this on a computer that is not your own. That would be bad.

Step 1: Create Ophcrack Live CD

Firstly, head on over to the ophcrack website and on the homepage click download Ophcrack Live CD, as shown in the pictures. Then you have a choice between Ophcrack XP LiveCD and Ophcrack Vista LiveCD. Choose whichever is appropriate and then save it to your computer. It is approximately 450 MB, so it could take a while to download (about 45 minutes and up at 1.5 M). When it is done, you move onto burning.

If you know how to burn an image to a CD and have a program you prefer to use, please just burn the image to a disc. If not, there is a free program that can help you – BurnCDCC.

Step 2: Set Locked Computer to Boot from CD

To start with, when your computer turns on it should ask you to press a key or a number of keys to enter BIOS Setup Utility. Some common keys are Delete, F1, F2, F10, Ctrl+alt+Enter or Ctrl+alt+Esc.

When you press them, you’ll enter the BIOS Setup Utility. Use the arrow keys to select the BOOT tab, then change the Boot Device Priority: Set 1st Boot Device to CD-ROM.

Press F10 to save your changes.

Step 3:  Crack Windows Password

Pop your CD in the CD-ROM drive of your locked computer. As your computer boots, it should say something along the lines of “If you want to boot from a CD, press any key now…….”. If not turn it off and turn it on again with the CD already in the drive, or in another drive. If it boots correctly, it should come up with a screen like in the picture. If it is not automatically running, just press start in the top bar.

Now comes the easy part. Just sit back and wait for the progress bar to finish at the bottom. Then if you look in the NT Pwd list, your password should be there, in the list with your username.

After you have the password you need, you can simply press on the section like the start menu and select turn off, or something similar and it should shut down the computer. Then eject the Ophcrack Live CD and restart the computer, you should be able to log into your computer with the recovered password. You’re Done!
