Abstract:The presentation will be a demonstration of new techniques for wordlist and rule generation to help crack quality passwords with a success rate above 90%.

Bio:Yiannis works at KPMG LLP (UK) as a pentester. He managed to convince the Academia that his password cracking obsession is a good subject for an MSc thesis :) . In his MSc thesis he listed practical attacks on passwords and applied them against hashes disclosed from recent leaks. Yiannis argued that usage of standards such as FIPS181 (pronounceable random passwords) actually weakens password strength. Yiannis is an active member of Team Hashcat and has attended CMIYC and Hashrunner competitions. He is well known for his rulesets and wordlists. He makes his own rules both in life and password cracking! He recently presented at various seminars such as OWASP Chapters and BSides London. He was interviewed on the subject of password cracking by BBC and ArsTechnica.
