Vulnerability in Tire Pressure Monitoring Systems Enables Vehicle Tracking

A study by IMDEA Networks Institute reveals that Tire Pressure Monitoring Systems (TPMS) in vehicles from major brands like Toyota, Mercedes, and Hyundai transmit unencrypted data, allowing for passive tracking of vehicles and drivers. Over a 10-week period, researchers captured more than 6 million signals from 20,000 vehicles using inexpensive receivers, indicating significant privacy risks associated with these systems.
