Rules:

KoreLogic used a variety of custom rules to generate the passwords. These _same_ rules can be used to crack passwords in corporate environments. These rules were originally created for the tool John the Ripper. KoreLogic performed a very rough translation to rules that can be understood by the 'hashcat' tool. The rules below can be downloaded, placed in hashcat's /rules/ directory and accessed via the command line using the -r command line option. This is _not_ a complete list of all rules that was used for the contest, but a subset of rules that were easy to convert to hashcat format.

Note: Many of these rules can be rewritten or condensed using OCLHashCat
