Multiple Linux distros on one usb drive: Ophcrack 31 August, 2008

Name:    Ophcrack
Website:  http://ophcrack.sourceforge.net
Wiki:        http://en.wikipedia.org/wiki/Ophcrack
Size:       72 MB without tables. Tables are much larger.

Ophcrack is a great little utility to recover “lost” (*cough*) Windows passwords. It relies on different sets of hash tables, which speed up the process significantly. When a user creates any account, their password is entered, and a hash is created based on that password. Entering the same password on login will create the same hash, if the password is correct. The tables are a generated list of possibilities, and the hashes produced by those password. XP and Vista need different tables, because they use different algorithms. The tables can crack alphanumeric (no special characters) passwords smaller than 14 characters (otherwise you need the “special” tables which are considerably larger – 10 GB). The normal tables fit on one CD. You can use Ophcrack on a usb stick, but you’ll need to be able to fit ~500 MB of tables on the stick, or carry around the tables on a CD.

Walkthrough to come soon.
