Engineers and tech people like Craig Smith (who made a great book about hacking cars) never stop warning about car security. Saying that modern cars ain't secure and can be hacked from the outside (cellular) and eventually be controlled.
If a hacker is able to connect to the car via cellular, he will be connected to the infotainment system right ?
So this means that the infotainment console of those cars are directly connected to every single node/ECU of the car (comfort, body and engine) ?
It seems weird to me because on the car I own (without cellular), the infotainment system isn't connected to every ECU. If I want to control the body, I have to find wires that are connected to it, same for the comfort and engine. But none of them are linked together.
Can someone clarify this please ?
Many thanks in advance.
