Researchers at Ledger’s Donjon security team have demonstrated a laser-based fault injection attack against the Raspberry Pi RP2350 microcontroller, bypassing its secure boot and TrustZone protections. This development highlights the persistent challenge of hardware security, as even chips with robust defenses can be compromised through sophisticated physical attacks. The technique, requiring a $250,000 setup and precise targeting of the debug register, suggests that attackers will continue to find novel ways to circumvent security measures, emphasizing the need for layered defenses and ongoing hardware vulnerability research.
