Sirius XM flaw could’ve let hackers remotely unlock and start cars

A vulnerability affecting Sirius XM’s linked automobile providers may’ve let hackers remotely begin, unlock, find, flash the lights, and honk the horn on vehicles. Sam Curry, a safety engineer at Yuga Labs, labored with a gaggle of safety researchers to find the flaw and outlined their findings in a thread on Twitter (through Gizmodo).

Along with offering a satellite tv for pc radio subscription, Sirius XM additionally powers the telematics and infotainment techniques utilized by a lot of auto producers, together with Acura, BMW, Honda, Hyundai, Infiniti, Jaguar, Land Rover, Lexus, Nissan, Subaru, and Toyota. These techniques accumulate a complete lot of details about your automotive that’s simple to miss — and will pose potential privateness implications.

Individually, Curry uncovered another flaw throughout the MyHyundai and MyGenesis apps that might additionally probably let hackers remotely hijack a automobile, however says he labored with the automaker to repair the problem. White hat hackers have discovered related exploits previously. In 2015, a safety researcher uncovered an OnStar hack that might’ve let dangerous actors find a automobile remotely, unlock its doorways, or begin the automotive. Across the identical time, a report from Wired confirmed how a Jeep Cherokee might be remotely hacked and managed with somebody on the wheel.
