The researchers point to a recent report showing that a typical luxury sedan now contains about 100 megabytes of code that controls 50 to 70 computers inside the car, most of which communicate over a shared internal network.
"In a lot of car architectures, all the computers are interconnected, so that having taken over one component, there's a substantive risk that you could take over all the rest of them. Once you're in, you're in," says Stefan Savage, an associate professor in the department of computer science and engineering at the University of California, San Diego, who is one of the lead investigators on the project.
