Reverse-engineering a $35 backup camera display (AMT630A)
A research team reverse‑engineered the AMT630A, a $35 backup‑camera display, exposing its internal firmware and communication protocol. Using hardware debugging and firmware analysis, they mapped how the unit processes video signals and interfaces with the vehicle’s CAN bus, revealing hard‑coded keys and no authentication. The study highlights security gaps in inexpensive automotive components and potential exploitation paths.
