Researchers Warn of Millions of Vulnerable Car Alarms That Can Be Hacked to Track, Unlock, and Disable Vehicles
Security researchers have identified a widespread vulnerability in millions of vehicles across the United States stemming from aftermarket alarm systems installed by dealerships. These devices, often added to vehicles without clear disclosure or the buyer's explicit consent, remain functional even when owners attempt to disable them.
The vulnerability allows attackers to remotely access the alarm systems and perform a range of malicious actions. Hackers could potentially track vehicle locations in real-time, unlock car doors, and even disable critical vehicle functions. The research highlights how these aftermarket devices create an expanded attack surface that was not part of the original vehicle design.
Researchers are urging vehicle owners to check whether their cars contain these third-party alarm systems and to apply any available patches or seek professional removal. The discovery underscores ongoing concerns about the security implications of connected vehicle technology and the risks introduced by unvetted third-party hardware integrated into automotive systems.
