### The Vulnerability in Tire Pressure Monitoring Systems A recent study from the Madrid-based IMDEA Networks Institute has shed light on a potential vulnerability in tire pressure monitoring systems (TPMS). The study found that TPMS broadcast a unique ID that can be reliably tracked, allowing for the potential tracking of vehicles without reading their license plates. ### How the Vulnerability Works Researchers used this unique ID as a basis for tracking locations of vehicles without reading their license plates. They built a network of radio receivers at $100 a pop and collected roughly six million signals from approximately 20,000 cars over 10 weeks. The study found that signals could be received from more than 160 feet away, even when receivers were located inside buildings. ### Implications for Vehicle Security The study's findings have significant implications for vehicle security.

### The Vulnerability in Tire Pressure Monitoring Systems
A recent study from the Madrid-based IMDEA Networks Institute has shed light on a potential vulnerability in tire pressure monitoring systems (TPMS). The study found that TPMS broadcast a unique ID that can be reliably tracked, allowing for the potential tracking of vehicles without reading their license plates.
### How the Vulnerability Works
Researchers used this unique ID as a basis for tracking locations of vehicles without reading their license plates. They built a network of radio receivers at $100 a pop and collected roughly six million signals from approximately 20,000 cars over 10 weeks. The study found that signals could be received from more than 160 feet away, even when receivers were located inside buildings.
### Implications for Vehicle Security
The study’s findings have significant implications for vehicle security. If a network of inexpensive wireless receivers can quietly monitor the patterns of cars in real-world environments, it could reveal daily routines, such as work arrival times or travel habits. This information could also be used to track the movement of vehicles, potentially raising concerns about surveillance and data collection.
### Potential for Tracking and Surveillance
The study’s researchers also discovered how to match signals to individual tires on a vehicle to improve accuracy and intercept the tire-pressure readings themselves. This could reveal the type of vehicle, or whether it’s carrying a heavy load. While this technology could have practical applications, such as improving vehicle safety, it also raises concerns about the potential for tracking and surveillance.
### Regulatory Response
The study’s findings have prompted researchers to call for regulatory action to address the vulnerability in TPMS. Current regulations do not require cybersecurity protections like encryption or authentication, which may have contributed to the vulnerability. The study’s authors argue that regulators should take steps to address this risk and ensure the security of TPMS systems.
### Conclusion
The study’s findings highlight the potential risks associated with TPMS systems and the need for regulatory action to address these risks. As the automotive industry continues to evolve, it is essential to prioritize vehicle security and ensure that systems like TPMS are designed with security in mind.
