Presentation 1: Passwords cracking and countermeasure Abstract: "Although password hashing mechanisms are not directly exposed to the end user, they can still have a great impact on security in the event of a security breach. This talk describes the more common schemes together with the more common mistakes made, and shows how to crack passwords of several popular formats if the hash should be obtained. In particular, we cover hashcat, plus John the Ripper as well as hardware acceleration."
