Raspberry Pi hands out prizes to all in the RP2350 Hacking Challenge

Raspberry Pi ran a public challenge to encourage disclosure of weaknesses in the RP2350 microcontroller; four entrants used physical-attack techniques (power/voltage glitches, laser/focused ion beam, and EM fault injection) to extract a secret from the chip's OTP memory. Raspberry Pi awarded prizes to the successful teams, commissioned Hextree to evaluate secure boot and fault-detection bypasses, and plans mitigations (some requiring hardware changes) while noting all attacks require physical access.
