On the road hacking?

I read an article this week by the head of Daimler Informatics discussing the very real fears of the guy behind you being able to turn off your lights, activate brakes etc. via your cars internet connection(s). Is GM able to do any of this at the moment? I thought that they have emergency response capabilities so if they do, someone else could learn to as well. Just curious what firewall, separate wireless connections for diagnostics versus internet are active in the VOLT.

Actually onstar can do the slow down for the police mode. But that being said I think they have to verify everything like the car is stolen or the police have a right to disable.

Hypothetically speaking:

Most of the communication between the Volt and Onstar HQ is via SMS over CDMA, correct? In other words, nothing more than text messages back and forth?

Assuming one could assemble a CDMA micro-cell and get the Volt to connect to it (thinking it was just another cell tower) it doesn't seem horribly convoluted to craft a command and send it to the car. To the Volt it would appear as if it came across the real cell network direct from Onstar.

Of course, I would expect that there must be some form of encryption... If Onstar signals were bouncing back and forth in plaintext I think we would have heard about it by now.

I read an article about three years ago that a Chevy Malibu was hacked remotely, using a transceiver in another vehicle to get into the CAN system and transmitting new CAN commands. It wasn't easy to do, and the vehicle doing the "hacking" had to be close enough. I tried a search but I cannot find it again.
