About
Background: Professor Aggarwal and his team have created a system and method of probabilistic passwords cracking. This technology is a novel password cracking system that generates password structures in highest probability order. Our program, called UnLock, automatically creates a probabilistic context-free grammar (CFG) based upon a training set of previously disclosed passwords. This CFG then allows to generate word-mangling rules, and from them, password guesses to be used in password cracking attacks. Advantages: Effectiveness demonstrated on real password sets Technology capable to crack 36% to 93% more passwords than John the Ripper, a publicly available standard password cracking program. Tested in digital forensic missions
