Lasers Unlock the 'Unbreakable' RP2350: A New Frontier in Hardware Hacking

The RP2350 microcontroller, designed by Raspberry Pi, boasts advanced security features like ARM TrustZone and permanent debug disabling. However, security researchers have demonstrated a hardware exploit using laser fault injection. By precisely targeting the chip's circuitry, attackers can bypass security lockdowns and re-enable debug access. This vulnerability highlights the ongoing battle between silicon-level security measures and physical attack vectors, proving that 'permanent' software-based locks can still be picked with high-tech hardware tools.
