New cars vulnerable to hacks that could leave thousands dead: Report

A consumer advocacy group has warned that automakers are rolling out new vehicles increasingly vulnerable to hackers, which could result in thousands of deaths in the event of a mass cyber attack.

In a new report entitled "Kill Switch: Why Connected Cars Can Be Killing Machines And How To Turn Them Off", Los Angeles-based Consumer Watchdog said cars connected to the Internet are quickly becoming the norm but constitute a national security threat.

"The troubling issue for industry technologies is that these vehicles' safety-critical systems are being linked to the Internet without adequate security and with no way to disconnect them in the event of a fleet-wide hack," the report said.

It said industry executives were aware of the risk but were pushing ahead in deploying the technology in new vehicles, putting corporate profit ahead of safety.

The report was based on a five-month study with the help of more than 20 whistle-blowers from within the car industry.

The group of car industry technologists and experts speculated that a fleet-wide hack at rush hour could leave about 3,000 people dead.

"You can control all sorts of aspects of your car from your smartphone, including starting the engine, starting the air-conditioning, checking on its location," said one of the whistle-blowers, who were not identified.

"Well, if you can do it with your smartphone, anybody else can over the Internet."

The reports recommends all connected vehicles be equipped with an Internet kill switch and that all new designs should completely isolate safety-critical systems from Internet-connected infotainment systems or other networks.

"Connecting safety-critical systems to the Internet is inherently dangerous design," said Mr Jamie Court, president of Consumer Watchdog.

"American car makers need to end the practice or Congress must step in to protect our transportation system and our national security."

Representatives from several of the car companies mentioned in the report, including GM, Toyota and Ford, could not immediately be reached for comment.
