Hidden Car Alarm Devices Found Hackable, Exposing Millions of US Vehicles

Security researchers have warned that a hidden alarm device, installed by dealerships in millions of vehicles across the United States, carries serious cybersecurity vulnerabilities. The devices were fitted into cars during the sales process and often left in place even when buyers did not request or want them. Attackers exploiting the flaws could remotely unlock, track, or completely disable affected vehicles. Owners and dealerships are being urged to apply available patches immediately to mitigate the risk.
