BOSTON/DETROIT (Reuters) -- A researcher is advising drivers to halt the use of a mobile app for General Motors' OnStar vehicle communications system, saying hackers can exploit a security flaw in the product to remotely unlock cars and start engines.
"White-hat" hacker Samy Kamkar posted a video today saying he had figured out a way to "locate, unlock and remote-start" vehicles by intercepting communications between the OnStar RemoteLink mobile app and the OnStar service.
Kamkar said he plans to provide technical details on the hack next week in Las Vegas at the Def Con conference, where tens of thousands of hacking aficionados will gather to learn about new cybersecurity vulnerabilities.
Kamkar released the video a week after Fiat Chrysler Automobiles recalled some 1.4 million vehicles after hacking experts demonstrated a more serious vulnerability in the Jeep Cherokee. That bug allowed them to gain remote control of a Jeep traveling at 70 miles per hour on a public highway.
