Ophcrack is a Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventory of the method. It comes with a GTK + Graphical User Interface and runs on Windows, Mac OS X (Intel CPU) as well as on Linux.

Remarkably again, Ophcrack available as a LiveCD, so it does not need the installation process and does not need the admin password, only need access to a computer can boot from the CD (usually the default BIOS boot sequence when the computer is started from the CD / DVD ROM, so do not worry ):-D. Ophcrack LiveCD is a SLAX-based Linux (derived from Slackware) and already there are Ophcrack and Rainbow alpanumerik Table for cracking passwords.

The bottom line is it uses Linux Ophcrack LiveCD so that it can directly mount the file system of Windows without having to log into Windows and read the Hash file (windows \ system32 \ config) and dump into a text file which can then be used directly in the crack . And incredibly, does not need tools like JTR again, because crack is done by using Ophcrack Rainbow Table and deliver results very quickly.

The important things to look for here are the accounts listed in the User column and the passwords listed in the NT Pwd column. If the user account you’re looking for isn’t listed, Ophcrack didn’t find that user on your computer. If the NT Pwd field is blank for a particular user, the password has not been recovered yet.

As you can see in the example above, the passwords for the Administrator and Guest accounts are listed as empty. If you were cracking a password for a user that Ophcrack shows as empty, you now know that you can log on to the account without a password at all, assuming that the user account is enabled.

Look toward the bottom of the user list – see the Andi user account? In under one minute, Ophcrack recovered the password to this account – Secret .
