>Unlike a website, a car requires access to a physical, proprietary interface to embedded components. That's not necessarily true. For example, my car's ECU can be reprogrammed using the instrumentation bus. The instrumentation bus can be accessed using the wires that interface with the CD changer. That means that the audio system is on the same network as the ECU -- and if I had a Bluetooth adapter, that'd likely be on the same network as well. Indeed, researchers can disable electronically controlled brakes via Bluetooth: http://www.technologyreview.com/computing/35094/?ref=rss&a=f http://www.technologyreview.com/computing/35094/?ref=rss&#38... >Patches are impossible I've had to take my car in for patches a few times. Where there is software, there will be patches required. At the end of the day, I doubt we will be seeing assassinations via car hacking. But I wouldn't call it impossible.
