Pulsed laser diodes may offer a smaller, less expensive alternative to conventional optoacoustic laser sources; however they do not provide pulse rate…

Laser Fault Injection on a Budget: RP2350 Edition

In August 2024, Raspberry Pi introduced the RP2350 microcontroller. This part iterates over the RP2040 and comes with numerous new features. These include security-related capabilities, such as a Secure Boot implementation. A couple of days after this announcement, during DEFCON 2024, an interesting challenge targeted at these new features was launched: the RP2350 Hacking Challenge. After some work and the development of a fully custom “Laser Fault Injection Platform”, I managed to beat this challenge and submitted my findings to Raspberry Pi. This article will provide technical details about this custom platform, including manufacturing files for those interested in building their own. Additionally, I will explain how injecting a single laser-induced fault can bypass the Secure Boot feature of the RP2350.
