The CAN bus is shared by a number of devices, each with its own microprocessor and thus (in principle) potentially subject to exploits that cause it to run malicious code. Some of the devices on the bus interact with the outside world via cellular, Wifi, Bluetooth and USB. The disturbing idea here is that your car is basically an internally-unfirewalled network of computers that can kill you if they malfunction.

I won't say it's sufficiently locked down, but as we recently saw - not even Apple got that completely right - but there are several layers of protection(s) on the various communication bus-es and computers. At least on European Manufacturers. I agree that this needs more hardening, but reading this comments one would get an idea that a 12 years old kid with a 10EUR dongle can hack any car. When in reality, stuff is a lot harder to do.

- mtgx 6y agoBecause firewalls are such a panacea for security?
