Tire pressure "transmissions are sent without any encryption or secure mechanisms and include a unique identifier. This allows anyone with affordable equipment like a low-cost spectrum receiver and a standard off-the-shelf antenna to capture and track them throughout time and space."

Please say more. What does one buy? How easy is it for people with only intermediate tech skills to do? Are there any tutorials explaining all of this?

@dangoodin @ghostsarespooky This is a screenshot from a HackRF with PortaPack. TPMS decoding has been a feature since the introduction of PortaPack H1 by Jared Boone in 2014, and he gave some talks about TPMS at hacker cons around that time.

@mossmann @ghostsarespooky

Interesting. So is the idea to regularly change the TPMS?

@dangoodin not wireless would be great (edit: that’s non trivial to do)

Don’t they need to power the sensor, hook it up to the car’s mini grid?
