Researcher reveals method to hack digital license plates in the US

A researcher has demonstrated a method to hack digital license plates made by Reviver, which has sold 65,000 units in the U.S. The technique involves removing a sticker and connecting a cable to rewrite the plate's firmware. Once modified, the hacked plates can change their display using a smartphone app. This vulnerability exists at the hardware level, meaning Reviver cannot fix it with a software update. To address the issue, Reviver would need to replace the chips in all affected plates. The incident raises questions about the security of digital license plates.
