074 - This Coconut Won't Open
Noah Holland and Joshua Stiebel, from the Michigan Tech Red Team, discuss their reverse engineering of Dormakaba's SafeLock electronic access control systems. They detail how they discovered vulnerabilities in the MyFare Classic and Ultralight card formats, allowing them to clone keys and generate master keys using tools like the Proxmark3 and Flipper Zero. The conversation covers the limitations of Dormakaba's patching efforts, the importance of per-site AES keys, and the value of consulting old patents for protocol documentation.
