Virus drives into car computers

Antivirus companies are researching reports that computer viruses have attacked the onboard computers of cars.

Kaspersky Labs was contacted last weekend by a user asking how to disinfect the onboard computers of Lexus cars - the LX470, LS430 and Landcruiser 100. The user said that the infection occurred via a mobile phone.

Some mobile phone viruses already exist, such as Cabir and Skulls which spread by Bluetooth and infect handsets based on the Symbian operating system. Many Lexus cars include a navigation system that can connect to a mobile phone over Bluetooth to allow hands-free calls, and Kaspersky believes that Bluetooth could be used to transmit a virus to a car's GPS navigation system.

However, it is unclear which operating system Lexus uses for its navigation system. The company had not responded for requests for comment at the time of writing.

Eugene Kaspersky, head of antivirus research at Kaspersky Labs, said: "We know that car manufacturers are integrating existing operating systems into their onboard computers - take the Fiat and Microsoft deal, for instance. If infected mobile devices are scary, just think about an infected onboard computer."

David Emm, senior technology consultant for Kaspersky Labs, said it was plausible that mobile phones could infect cars.

"It's certainly a possibility, but at this stage it seems theoretical," said Emm. "The question is whether [onboard computers] have been subjected to attacks from [devices running the] Symbian operating system. I suspect that this will be done with a handset."

Kaspersky is still researching the reports.

Until two-way wireless transmissions were banned in races, Formula One racing cars were equipped with antivirus software to prevent virus attacks on the car's operating system.
