Experts hope to shield cars from viruses

Intel's McAfee unit, which is best known for software that fights PC viruses, is one of a handful of firms that are looking to protect the dozens of tiny computers and electronic communications systems that are built into every modern car.

Security experts say that automakers have so far failed to adequately protect these systems, leaving them vulnerable to hacks by attackers looking to steal cars, eavesdrop on conversations, or even harm passengers by causing vehicles to crash.

"You can definitely kill people", said John Bumgarner, chief technology officer of the U.S. Cyber Consequences Unit, a non-profit organization that helps companies analyze the potential for targeted computer attacks on their networks and products.

To date there have been no reports of violent attacks on automobiles using a computer virus, according to SAE International, an association of more than 128,000 technical professionals working in the aerospace and the auto industries.

Yet, Ford spokesman Alan Hall said his company had tasked its security engineers with making its Sync in-vehicle communications and entertainment system as resistant as possible to attack.

A group of U.S. computer scientists shook the industry in 2010 with a landmark study that showed viruses could damage cars when they were moving at high speeds. Their tests were done at a decommissioned airport.

SAE International charged a committee of more than 40 industry experts with advising manufacturers on preventing, detecting and mitigating cyber attacks.

U.S. computer scientists from California and Washington state issued a second report last year that identified ways in which computer worms and Trojans could be delivered to automobiles – via onboard diagnostics systems, wireless connections and even tainted CDs played on radios systems.

They did not say which company manufactured the cars they examined, but did say they believed the issues affected the entire industry, noting that many automakers use common suppliers and development processes.
