Using OphCrack

Using Ophcrack,You can crack account password of almost all the Windows till date,And since OphCrack is the fastest password cracking tool,it wont take more than 4-5 minutes to crack a password.So let's begin -


 

What Do You Need ?

BackTrack 5 Live DVD.
Rainbow Files (i'll tell you what it is.)
Physical Access to victim PC.

So What-The-Hell is Rainbow Files ?

First thing that pops in mind when reading rainbow files is the collection of rainbows and unicorns flying,but no,Rainbow Files/Tables are basically huge sets of precomputed tables filled with hash values that are pre-matched to possible plaintext passwords. The Rainbow Tables essentially allow hackers to reverse the hashing function to determine what the plaintext password might be. It's possible for two different passwords to result in the same hash so it's not important to find out what the original password was, just as long as it has the same hash. The plaintext password may not even be the same password that was created by the user, but as long as the hash is matched, then it doesn't matter what the original password was.

So What Do I Need To Do ?

You need to download the rainbow tables matching to the OS Version of your victim PC,Get Them Here.You can download the smaller files because they will work,unless your victim is the Head of FBI who uses 28 letter long password.NOTE : the vista files will work for Windows 7 and Windows 8 too.
