Description:

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 of cracking significantly more passwords in the same number of guesses as compared to publicly available standard password cracking systems.
  • Tested in digital forensic missions
