Related: http://illmatics.com/Remote%20Car%20Hacking.pdf http://illmatics.com/Remote%20Car%20Hacking.pdf I used to think that, however vulnerable this kind of installation might be, at least it'd be limited in scope to the IFE and climate control stuff, because no one would be stupid enough to make it possible for the IFE and climate control stuff to talk to the actual driving controls, if for no other reason than because there's no sensible excuse for doing so. Boy, was I optimistic. Now I'm not, but I'm gladder than ever that my car was made in 1997.

I work in 'automotive' software industry, and the trend at the moment is to have /everything/ running on as few CPUs as they can... That mean the infotainment and brakes might end up on the same physical die in the near future... And when you listen to the people who make that stuff up, and almost sounds like a good idea ;-)

  Why is this? The marginal cost of electronic components must be miniscule compared to the production costs of the automobile as a whole...

    Well it's the 'solution' principle, SoC manufacturers want to provide something that can do as much as they can to cover the ECU, Infotainment, dashboard, and every other little bits they can as one single 'package'. The SoC gets a lot bigger too, since it now need to provide the all around cameras for example, there's a push to use that power to do 'other stuff'. A few years back I had a car that had a short when it was raining a lot -- the (digital) speedo and stuff with reboot -- but the car continues working all the same... Soon I don't /know/ what'll happend if the SoC gets compromised (either maliciously, or just accidentally). I guess we'll have to have a few accidents for people to 're-discover' that redundancy and the egg+basket principle are a good idea after all...
