Saflok locks are present in many hotels and apartments across North America. These locks rely on poorly-secured offline authentication mechanisms, leaving them vulnerable to attackers with basic knowledge about how the system operates. Following up on the initial "Unsaflok" presentation at DEF CON 32 by Lennert Wouters and Ian Carroll, this talk will touch on areas of the system not discussed in the original presentation, such as the handheld programmer, lock programming interface, clarity about the bit fields and unencrypted data in credentials, for yet another example of why you don't rely on security-through-obscurity for security products.
