Just seen this article on Wired Magazine: Car Hack Technique Uses Dealerships to Spread Malware
At the Derbycon hacker conference in Louisville, Kentucky last week, security consultant Craig Smith presented a tool designed to find security vulnerabilities in equipment that’s used by mechanics and dealerships to update car software and run vehicle diagnostics, and sold by companies like Snap-On and Bosch. Smith’s invention, built with around $20 of hardware and free software that he’s released on GitHub, is designed to seek out—and hopefully help fix—bugs in those dealership tools that could transform them into a devious method of hacking thousands of vehicles.
If a hacker were to bring in a malware-harboring car for service, the vehicle could spread that infection to a dealership’s testing equipment, which in turn would spread the malware to every vehicle the dealership services, kicking off an epidemic of nasty code capable of attacking critical driving systems like transmission and brakes, Smith said in his Derbycon talk. He called that car-hacking nightmare scenario an “auto brothel.”
“Once you compromise a dealership, you’d have a lot of control,” says Smith, who founded the open source car hacking group Open Garages, and wrote the Car Hacker’s Handbook. “You could create a malicious car…The worst case would be a virus-like system where a car pulls in, infects the dealership, and the dealership then spreads that infection to all the other cars.”
