RuleProcessorY & Gramify - Rule Optimization & Password Analysis tools
Saturday August 12, 14:00 – 15:55, Caucus Boardroom, Forum
Niels Loozekoot
The RuleProcessorY and Gramify tools are new tools that support password-cracking efforts. RuleProcessorY offers a method of optimizing hashcat rule-files so that you can prevent duplicates across multiple attacks better, leading to a shorter runtime. Additionally it can process rules as hashcat would with an additional support for multi-byte/multi-character rules (inserts & replace primarily). Gramify offers an easy method to create base words and candidates to utilize with wordlist and combination attacks by splitting data by words, characters, or character-set. This can help with password phrases, quotes, sentences, combinator attacks, and extracting base-words from passwordlists.
Working as Pentester Niels has an extensive background in the security field. Niels has a background in web-development and knows his way around C, C++, C#, and Python and is active in the password cracking/research communities of Hashcat, Hashkiller, and HashMob. Winning in the CrackTheCon password cracking contest, and achieving 3rd place in both the CrackMeIfYouCan 2021 & 2022.
