Ophcrack LiveCD 3.6.0 is a completely self-contained, bootable version of Ophcrack 3.6.0 - the easiest and most effective tool that I've ever found to 'crack' your forgotten Windows password. So, I'm trying to use Ophcrack. When I boot it, everything works smoothly (CD boots up, enters Ophcrack, partitions found) But then it says: Tables found: /mnt/sr0.

| OPHCRACK 3.6.0 (Time-Memory-Trade-Off-Crack) |
| A windows password cracker based on the faster time-memory trade-off using |
| rainbow tables. |
| This is an evolution of the original ophcrack 1.0 developed at EPFL |
| (http://lasecwww.epfl.ch/~oechslin/projects/ophcrack) |
| Ophrack 3.6.0 comes with a Qt Graphical User Interface which runs on Windows, |
| Mac OS X as well as on Unix. |
| GETTING and INSTALLING OPHCRACK |
| Ophcrack 3.6.0 can be downloaded from sourceforge: |
| http://ophcrack.sourceforge.net |
| The Windows version comes with an installer that suggests automatic |
| install or download of the tables. |
| The linux version is a source package. It can be compiled and |
| installed using the './configure', 'make' and 'make install' |
| commands. The tables have to be downloaded by hand, from the URL given |
| above. |
| HOWTO |
| This howto assumes you have already installed ophcrack 3 and downloaded the ophcrack rainbow tables you want to use. It also assumes that you understand how to use third party tools like pwdump or fgdump (http://www.foofus.net/fizzgig/) to dump the SAM of a Windows system. |
| Ophcrack and the ophcrack LiveCD are available for free at the ophcrack project page (http://ophcrack.sourceforge.net/). |
| Ophcrack rainbow tables are avaible at ophcrack rainbow tables page (http://ophcrack.sourceforge.net/tables.php). The XP free small, XP free fast and Vista free rainbow tables are free. The others ophcrack rainbow tables are sold by Objectif Securite. |
| First step |
| This step is optional but will speed up the cracking process. |
| Run ophcrack and set the number of threads under the Preferences tab to the number of cores of the computer running ophcrack plus one.For example, for an old processor set the number of threads to 2, for a Core 2 Duo to 3 and for a Core 2 Quad to 5. If you change this value, you have to exit ophcrack and to restart it in order to save the change. If you don't exit and restart, the new number of threads will not be taken into account by the program. |
| Second step |
| This step is mandatory. |
| Load hashes using the Load button. You can either enter the hash manually (Single hash option), import a text file containing hashes you created with pwdump, fgdump or similar third party tools (PWDUMP file option), extract the hashes from the SYSTEM and SAM files (Encrypted SAM option), dump the SAM from the computer ophcrack is running on (Local SAM option) or dump the SAM from a remote computer (Remote SAM option). |
| For the Encrypted SAM option, the SAM is located under the Windows system32/config directory and can only be accessed for a Windows partition that is NOT running. For the Local SAM and Remote SAM options, you MUST logged in with the administrator rights on the computer you want to dump the SAM. |
| Third step |
| This step is optional but will speed up the cracking process. |
| Delete with the Delete button every user account you are not interested in (for exemple the Guest account). You can use the Ctrl key to make multiple selection. Ctrl-a will select every loaded hash. |
| Keep in mind that the time needed to crack password hashes with rainbow tables is proportional to the number of hashes loaded. With a brute force attack the cracking time is NOT dependant on the number of unsalted hashes loaded. That's why it's advisable to remove any unnecessary user account with the Delete button. |
| Fourth step |
| This step is mandatory. |
| Install (Tables button), enable (green and yellow buttons) and sort wisely (up and down arrows) the rainbow tables your are going to use. Keep in mind that storing the rainbow tables on a fast medium like a hard disk will significantly speed up the cracking process. |
| Here are a few guidelines : |
| * If you want to crack LM hashes as found on Windows XP by default (the LM Hash column is never empty on the ophcrack main window), first install and enable either the XP free small (if you have less than 512MB of free RAM) or the XP free fast (if you have more than 512MB of free RAM). Do NOT enable both of them since this is generally useless and will slow down the cracking process. Then install and enable the Vista free tables set. Finally install and enable the other XP rainbow tables you may have (XP special, XP german) and Vista one (Vista special). Sort the rainbow tables with the up and down arrows the following way : first the XP free then the Vista free then the XP special after that the Vista special and finally the XP german. |
| * If you want to crack NT hashes as found on Windows Vista by default (the LM Hash column is always empty on the ophcrack main window), first install and enable the Vista free tables set. Then install and enable the Vista special tables set. Disable every other XP tables sets since they are useless and slow down the cracking process. Sort the enabled rainbow tables with the up and down arrows the following way : first the Vista free then the Vista special. |
| * If you want to crack a mix of LM and NT enabled hashes (some accounts have their LM column empty, others have both the LM and NT columns filled with hashes) proceed the same way as 'If you want to crack LM enabled hashes'. |
| Fifth step |
| This step is mandatory. |
| Click on the Crack button to start the cracking process. You'll see the progress of the cracking process in the bottom boxes of the ophcrack window. When a password is found, it will be displayed in the NT Pwd field. You can then save the results of a cracking session at any time with the Save button. |

Hey there,
So I was cleaning my pc by going back to the original state and when finished I created a new password. However I was a bit drunk and probably misspelled it. However after many tries I gave up and searched for other solutions. This lead me to Ophcrack which I downloaded on a DVD and tried to run. But it gave an error about not finding the requested table(s). Now after a lot of tries with other programs and bootable USB's etc. it just won't work. Can anybody help me with this issue? I've got an Windows 7 64x OS.
