DEF CON 33 - Cash, Drugs, and Guns - Why Your Safes Aren't Safe - Mark Omo, James Rowley

Mark Omo and James Rowley explain how they discovered vulnerabilities in SecuRam digital safe locks that allow them to be cracked using a Raspberry Pi.

When Liberty Safe was found to have provided safe unlock codes to authorities, it made us wonder; how was it even possible for Liberty to do this? Our talk will cover the vulnerabilities we found and journey into the various families of locks made by SecuRam, the OEM of safe locks used by Liberty Safe and other Safe vendors. Our exploration began with an “analog” lock from Liberty Safe but quickly expanded to SecuRam’s “digital” lock lines, where we found a debug port that allowed access to all firmware and data. Through this, we discovered that codes are stored on the externally accessible keypad, rather than securely inside the safe (as well as other issues). These locks, deployed widely in consumer, and commercial safes at major retail chains exhibit vulnerabilities that enable opening them in seconds with a Raspberry Pi. We invite you to our session to see us crack UL-certified High-Security Electronic Locks live!
