CRC Seminar Series - Cristofaro Mune, Niek Timmers

Summary

Cristofaro Mune and Niek Timmers presented a seminar on bypassing unbreakable crypto using fault injection on Espressif ESP32 chips. The presentation detailed how the hardware-based Encrypted Secure Boot implementation of the ESP32 SoC was bypassed using a single EM glitch, without knowing the decryption key. This attack exploited multiple hardware vulnerabilities, enabling arbitrary code execution and extraction of plain-text data from external flash. Why it matters: The research highlights critical security vulnerabilities in embedded systems and the potential for fault injection attacks to bypass secure boot mechanisms, necessitating stronger hardware-level security measures.
