This week researchers will present a study showing what could happen if a determined hacker went after the computer systems embedded in cars.
The researchers found that, among other things, an attacker could disable the vehicle’s brakes, stop its engine, or take control of its door locks.
All the attacker needs is access to the federally mandated onboard diagnostics port located under the dashboard in almost all cars today.
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.
The researchers say that their work shouldn’t yet be a cause for alarm, mainly because the exploits require access to the inside of a vehicle. But some of these systems can be accessed remotely, and the trend is to add even more wireless connectivity–for example, wireless automatic crash-response systems. The researchers say that other systems, such as satellite radios and remote-controlled door openers, could also become entry points.
