Securi-Tay 2025: Side-Channel Attacks on physical User Input
Darren Fürst analyzes Securi-Tay 2025: Side-Channel Attacks on physical User Input.
Summary
Overview: Electronic locks are becoming increasingly common on consumer-grade safes, particularly those used to secure guns. This talk explores vulnerabilities of several UL-listed Type 1 "High Security" electronic safe locks. Using side-channel attacks, we recover the owner-configured keycodes on two models of these locks from outside of locked safes without any damage to the locks or safes. Discussion includes power-line analysis, timing attacks, and lockout-defeat strategies on embedded devices.
