Reverse-Engineering the Supra iBox: Exploitation of a Hardened MSP430-Based Device
summary
Reverse engineering targets an MSP430 147 on Supra iBox hardware using a GoodFET, JTAG tests, external crystal and a camera xenon flash. Voltage glitching and the BSL timing attack both fail; the paparazzi attack (flash-induced photoelectric bypass) reliably exposes the BSL password and enables full firmware dump. Analysis finds a CIS code key shared per region, a hardware backdoor resistor that grants high-level access, a writable info page exploit combining RAM copy + mass erase, and practical PIN and cloning paths.
