The hackers are publicizing their work to reveal vulnerabilities present in a growing number of car computers. All cars and trucks contain anywhere from 20 to 70 computers. They control everything from the brakes to acceleration to the windows, and are connected to an internal network. A few hackers have recently managed to find their way into these intricate networks.
In one case, a pair of hackers manipulated two cars by plugging a laptop into a port beneath the dashboard where mechanics connect their computers to search for problems. Scarier yet, another group took control of a car's computers through cellular telephone and Bluetooth connections, the compact disc player and even the tire pressure monitoring system.
To be sure, the “hackers” involved were well-intentioned computer security experts, and it took both groups months to break into the computers. And there have been no real-world cases of a hacker remotely taking over a car. But experts say high-tech hijackings will get easier.
Charlie Miller, a St. Louis-based security engineer for Twitter, and fellow hacker Chris Valasek, director of intelligence at a Pittsburgh computer security consulting firm, released a report, including instructions on how to break into the cars' networks, at a hacker convention in August.
