Security researchers have revealed that signals from tire pressure monitoring systems (TPMSs), required in U.S. cars since 2007, can be used to track vehicles from 40-50 meters away using devices costing $100. TPMSs send a unique sensor identifier that never changes during the lifetime of the tire.
Vehicle Tire Pressure Sensors Enable Silent Tracking
Like many other features and systems in modern cars, tire pressure sensors leak sensitive data that can be abused by threat actors.
