A short blog post this week. Merely a link to an interesting article relating how some researchers have proven that you can hack a car's ECU via its tyre pressure monitoring sensors. As these are wireless, snooping their ID gives a hacker a way into the ECU, allowing manipulations from the benign activating of your windscreen wipers, to the dangerous disabling of your brakes.
Hack your car via the TPMS (ars technica).
