A Device Hidden in Cars Across the US Leaves Them Vulnerable to Hacking and Paralysis. Patch It Now

UC San Diego researchers found a serious flaw in the dealer-installed KARR Security System.

Within Bluetooth range, an attacker could unlock cars, disable alarms, honk horns, flash lights, or block ignition.

The issue may affect more than 2 million vehicles, and many owners may not even know the device is installed.

Acrisure Protection Group has released a firmware update, and owners are being urged to check for the unit and install the patch.
