Insert pen drive in the USB slot. 2. Open MagicISO and open the ophcrack-xp-livecd-2.3.1.iso, go to tables folder and create a new directory : vista_free 3. Extract and drag the contents of tables_vista_free to the folder you created in magic ISO. 4. Save the iso as ophcrack.iso on your desktop 5.

Boot from the flash drive : Step 1 : To bypass windows passwords : Choose hirens boot disk : Choose Kon-Boot or boot to mini windows xp and choose any of these : Step 2: HOW TO CRACK THE PASSWORD ... Boot from the flash drive, and choose OphCrack Choose the graphical mode - automatic. The computer will startup a linux load of ophcrack with both the xp rainbow tables as well as the vista tables. A rainbow table is a bunch of precomputed tables for decrypting hash functions. A semi detailed approach about the functionality is mentioned on wikipedia at http://en.wikipedia.org/wiki/Rainbow_table The boot up will automatically load the ophcrack tool, which scans for hash tables off SAM/Security lists to generate both the NT hash and LM hash. (http://en.wikipedia.org/wiki/LM_hash) which can be run thro the table list to get the actual password. I needed the password for #admin (which is used by most corporates), note the LM Hash and NT Hash You'll note that a password is generated on LM PWD1 / LM PWD2. But considering the fact that we're using the free tables a password like "a5h0k@R!mw3b" will be generated as ASHOKARIMWEB or A?H0K?R?MW?B note the LM/NT passwords like : LMhash:NThash that'll be 32 characters on each side of the ":" eg : 8b75c0f157f**7b******bd*f1f***ba:d0f****b1231e0f***a0e****de20f8f I've hashed out a few of the characters for obvious reasons Copy the same and paste it here : http://www.objectif-securite.ch/en/products.php At the bottom of the page, enter your hash and submit ... wait for a couple of seconds - and bingo you have the password including special characters!! HURAAY!!! cheers Karki
