Ophcrack 2.2 Password Cracker Released

Views: 149,839

Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow tables. This is a new variant of Hellman’s original trade-off, with better performance. It recovers 99.9% of alphanumeric passwords in seconds.

We mentioned it in our RainbowCrack and Rainbow Tables article.

Changes:

  • (feature) support of the new table set (alphanum + 33 special chars – WS-20k)
  • (feature) easier configuration for the table set (tables.cfg)
  • (feature) automatic definition of the number of tables to use at the same time (batch_tables) by queriying the system for the size of the memory
  • (feature) speed-up in tables reading
  • (feature) cleaning of the memory to make place for table readahead (linux version only)
  • (feature) improved installer for windows version
  • (fix) change of the default share for pwdump4 (ADMIN$)

  1. Ack, gotta hate comment spam.. Yeah, your old article made me discover Ophcrack , and I have to admit that it is awfully fast. Alot faster then Cain, which was my all time favorite, and it still is for some special tasks..

  2. Does this actually work on windows XP ?
    I have tried it on my account with a 15 lower case letter password . and it didnt work. But it didnt even say failed . It only said failed on the computer generated accounts

  5. Salam ! i want to learn hacking if any one intrest in teach me so plz contact wid me i’ll wait ur reply Allah Hafiz

  8. ok so what really sucks is being locked out of your laptop during the holidays! (no one is around, agh!) i had d/l ophcrack (cd live) and it revealed the original phrase i had instead of the additional characters i had added (and coincidentally, forgotten) so i’m not sure what to do from here on.

    do you have any recommendations?!?!

  12. ok, so i finally tried it however, it didn’t work. at first it showed the account to be locked and disabled. then ran it again, both times i set it to * blank password but it didn’t work. everytime it rebooted, the log in screen came on back to my account with the password i can’t crack. even with trying safe mode, both mine and the administrator had passwords. (guest wasn’t on although that got blanked out)

    btw, i am the administrator. why does my laptop not like me so?
    HELP?

  13. update for those who care: i tried the nt prgm again and it worked. i noticed something funky though. i had changed the password. (sort of reverted to the original phrase without the additional characters). this morning, i seemed to have been locked out of it again! so now i’m in and left it without a password. i’m wondering if this is going to happen each time i put in a password or if it only happened b/c it was similar to the previous one? any ideas?

  14. so i downloaded ophcrack and burned it to disc it loads and then it freezes and says something about an A drive can someone help

  15. Is there anything like this that can work for the online stuff? i’m big with the internet, and don’t carry my data around much, so…. Can anyone help?

  16. Ophcrack for Windows got me no where. I followed the directions as printed and even watched the how to video. Still it goes to the MS XP password screen. Never once giving me any indication that Ophcrack was working even though the CD is spinning like mad in the drive.

    UGH..!
