Millions of Cars Vulnerable to Hacking Due to Aftermarket Alarm Flaw
UC San Diego researchers discovered a severe vulnerability in the KARR Security System, an aftermarket car alarm installed in over 2 million US vehicles by dealers. The flaw allows hackers within Bluetooth range to unlock cars, disable alarms, or immobilize vehicles, often without owners' knowledge. A firmware update is available, but reaching unaware owners is a challenge.
