If that instrument have been to leak or be offered on-line—Rodriguez himself says he would not plan to publish his—he says anybody might use it to jailbreak their very own plate in a matter of minutes. “They only want to attach a cable and set up the brand new firmware, identical to for those who have been jailbreaking your iPhone,” Rodriguez says.
Rodriguez additionally notes that his hacking method might be used not simply by a driver who needs to jailbreak their very own plate, but in addition by somebody focusing on an unwitting proprietor of a plate too. If a hacker—or a parking valet or auto mechanic—might handle to take away a license plate and set up their very own firmware on it, Rodriguez warns, they might surreptitiously change their license plate quantity over the web by programming the plate to connect with a server the hacker managed.
Along with the bodily entry and time needed to tug off that hack, nonetheless, a license plate saboteur would additionally want to beat a characteristic of Reviver’s plates that sends a notification to the proprietor when it is indifferent from a car. That will require jamming the plate’s radio communications whereas tampering with it, Rodriguez notes, an added wrinkle that makes the assault even much less sensible, although maybe not unattainable.
Rodriguez is not the primary to hack Reviver’s techniques. In 2022, safety researcher Sam Curry discovered vulnerabilities within the firm’s net infrastructure that allowed him to make himself an administrator in its backend database, with the power to trace or change license plates at will. Not like Rodriguez’s {hardware} hacking, nonetheless, Reviver was in a position to shortly patch its web-based bugs to forestall Curry’s method.
Though Curry’s net hacking methodology was far simpler to tug off previous to Reviver’s patch than Rodriguez’s {hardware} hacking, he says that Rodriguez’s methodology would seemingly maintain actual enchantment for sure scofflaw drivers, who may wish to jailbreak their Reviver plates or just purchase pre-jailbroken plates on-line. “If you wish to swap your license plate quantity, James Bond model, then drive at loopy speeds or one thing, you possibly can change it for a number of hours and alter it again with out even pulling right into a parking storage,” says Curry. “The people who find themselves inflicting havoc on the street would in all probability be into this.”
Digital license plates are presently authorized to purchase and register in California and Arizona (Michigan additionally briefly allowed them), with many extra states contemplating legalizing them in years to come back. As that rollout continues, Rodriguez and Curry argue that license plate makers, transit regulators, and regulation enforcement all have to be conscious that any system that depends solely on license plates as an identifier could also be inclined to digital license plate hacking—with doubtlessly chaotic penalties.
“It’s best to assume individuals will mess with them,” says Curry. “And folks want to simply accept the implications of that.”

Up to date 11:55 am EST, December 17, 2024: Following publication, Reviver clarified that the weak module within the firm’s plates wouldn’t have GPS. We have up to date the story to replicate this new data.
