Millions of California-bought cars can be hijacked via Bluetooth

Summary

security Millions of California-bought cars can be hijacked via Bluetooth Aftermarket dealer-installed KARR/SWDS security systems all use the same secure key, say UCSD researchers At least 2.2 million vehicles fitted with dealer-installed KARR and SWDS security systems are vulnerable to nearby Bluetooth attacks that can unlock doors or prevent a stopped vehicle from starting, according to researchers at the University of California San Diego.

What that means, according to the researchers, is that anyone who knows the key, has a device with a Bluetooth connection, and can get within five yards of an affected vehicle can unlock it, make the horn honk, flash the headlights, or even prevent it from starting. “Instead of smashing a window to get access to a vehicle, thieves could simply connect remotely via Bluetooth to the device inside the vehicle, and make it unlock car doors,” Jerry Yu, coauthor on the research and UCSD compsci graduate, said in the release. KARR/SWDS devices are installed by dealerships. Along with providing key fob-like functions, they also serve as an antitheft device, allowing dealers and buyers to track cars with the devices installed in the case of theft. According to UCSD, the devices are typically sold as a paid upgrade at dealerships around the US. KARR says its products are available through more than 3,000 dealerships nationwide. Per the researchers, however, those devices remain active even if a buyer declines the service, meaning those who don’t have an active KARR/SWDS contract are still at risk. “Removing the devices is not trivial,” UCSD compsci PhD candidate and...
