Obtaining and Cracking Passwords

--------------------------------------------------------------------------------

The files that contain the password hashes reside in the registry. This obviously presents a problem due to the fact that you cannot access the files while windows is running. Thus, you have to use what youve learned in the previous tutorials and fire up an alternate OS. The one that we will be using is called Ophcrack.

Ophcrack can be downloaded from the official Ophcrack website at http://ophcrack.sourceforge.net/

Always grab the newest version whenever you download it. The current version is v2.3.1

Burn the image to a cd using an image burning program and your all set!

The windows registry is often referred to as a hive. Don't poke arround in it too long else your likely to get stung. That being said, if your inexpirenced and don't have much knowledge of the registry just grab the files and don't mess with anything else.

The files required by Ophcrack in order to crack the passwords are the SAM file and the SECURITY file. These are located under

C:\WINDOWS\system32\config

Just copy them to a flashdrive and then point to them when using Ophcrack
