Found an interesting article relating to the hacking of tire-pressure-monitoring-systems (TPMS).
The complete article can be found in the link above @ Technology Review, and was written by Robert Lemos.
A quote from the first page of the article:
"...The team could eavesdrop on communications and, in some circumstances, alter messages in-transit. That let the team give false readings to a car's dashboard. They could also track a vehicle's movements using the unique IDs of the pressure sensors, and even cause a car's ECU to fail completely"
The research team that discovered how to hack two
"popular" TMPSs is presenting their work at the
USENIX Security conference this week.
While a practical hack on a moving vehicle would be difficult at best, I thought it interesting that they could shadow a vehicle with directional antennas and effectively hack the ECU. Not fun!!!
