Ledger's Donjon research team demonstrated photon-emission-guided laser fault injection to bypass security measures and enable secure debug access on the RP2350 microcontroller. The technique uses photon emission analysis to precisely target vulnerable circuit locations for fault injection attacks.
Background
The RP2350 is Raspberry Pi's latest dual-core microcontroller featuring ARM Cortex-M33 with TrustZone. Laser fault injection is a side-channel attack technique used to bypass hardware security features on embedded devices.
