Wired: “Digital license plates sold by Reviver, already legal to buy in some states and drive with nationwide, can be hacked by their owners to evade traffic regulations or even law enforcement surveillance. Digital license plates, already legal to buy in a growing number of states and to drive with nationwide, offer a few perks over their sheet metal predecessors. You can change their display on the fly to frame your plate number with novelty messages, for instance, or to flag that your car has been stolen. Now one security researcher has shown how they can also be hacked to enable a less benign feature: changing a car’s license plate number at will to avoid traffic tickets and tolls—or even pin them on someone else. Josep Rodriguez, a researcher at security firm IOActive, has revealed a technique to “jailbreak” digital license plates sold by Reviver, the leading vendor of those plates in the US with 65,000 plates already sold. By removing a sticker on the back of the plate and attaching a cable to its internal connectors, he’s able to rewrite a Reviver plate’s firmware in a matter of minutes. Then, with that custom firmware installed, the jailbroken license plate can receive commands via Bluetooth from a smartphone app to instantly change its display to show any characters or image. That susceptibility to jailbreaking, Rodriguez points out, could let drivers with the license plates evade any system that depends on license plate numbers for enforcement or surveillance, from tolls to speeding and parking tickets to automatic license plate readers that police use to track criminal suspects. “You can put whatever you want on the screen, which users are not supposed to be able to do,” says Rodriguez. “Imagine you are going through a speed camera or if you are a criminal and you don’t want to get caught.”
