Dangerous New Car Threat - Hacking Tire Pressure Monitors Remotely

There’s a new vector for hacking your car’s computer wirelessly. Tire Pressure Monitoring Systems (TPMS) are a safety feature that have been mandatory on all new vehicles since 2008. TPMS are installed on each tire to monitor the air pressure in the tires and alert the driver when the pressure falls below a certain threshold. While TPMS have improved safety on the roads, they have also become a target for hackers. Yes another hacking game!

It turns out the attack potential is huge. In the U.S., the Tread Act mandated that every car built 2008 and on must have a tire pressure monitoring system built-in. It also turns out that car tire pressure monitors using unencrypted radio frequency for the communication between the tire and the receiver. TPMS sensor alarms are what turn on that annoying low tire pressure light we are all familiar with on your dash console. This typically refers to a flat tire or a tire that is low in pressure and wears the tires out quickly and reduces fuel economy, reduces traction and your safety.
