Hacker gains access to the RP2350 OTP secret by glitching the RISC-V cores
Engineer Aedan Cullen may be in line for the $20K prize.
Engineer Aedan Cullen went public with his Hacking the RP2350 presentation at the recent 38th Chaos Communication Congress (38C3), and there is a GitHub repo now published to accompany the video here. Cullen studied the RP2350 in detail before going for a voltage injection glitch attack on pin 53 of the RP2350 chip, which managed to turn on the 'permanently disabled' RISC-V cores and their debug access port, enabling him to read the secret.
