Ophcrack

Ophcrack is a free open source (GPL licensed) program that cracks Windows passwords by using LM hashes through rainbow tables.

The program includes the ability to import the hashes from a variety of formats, including dumping directly from the SAM files of Windows.

On most computers, ophcrack can crack most passwords within a few minutes.

This is a standalone plugin. Download ophcrack231-XXX.tar.gz, ophcrack-tables-xp-XXX.tar.gz, and ophcrack-tables-vista-XXX.tar.gz from SourceForge and extract them to your TFTP folder.

At the moment ophcrack isn't able to mount NFS/CIFS shares so we have included our own version ready for use with ERPXE.
