Vulnerabilities in Car Anti-Theft Device

Researchers at UC San Diego discovered vulnerabilities in the KARR Security System, an aftermarket car alarm installed in over 2 million vehicles in the US. The flaws allow hackers within Bluetooth range to send radio commands that can unlock the car, disable its alarm, or trigger certain functions like the horn or lights. Hackers can also disable the car's ignition, potentially stranding the driver. The vulnerabilities can be exploited by any hacker in close proximity to the vehicle.
