UCSD computer scientist Stefan Savage and colleagues will present their work at Usenix Security: they were able to disable the brakes on a 2013 Corvette by breaking into a Mobile Devices/Metromile Pulse dongle, used by insurance companies to monitor driving in exchange for discounts on coverage.
Metromile is also used by Uber to track its drivers. Metromile claims it has patched all the devices, but by scanning the Internet, the researchers were able to locate thousands of vulnerable vehicles on the road today.
Other insurance company/automotive telematics devices, including the Snapshot (mandated by Progressive Insurance), are also vulnerable. Federal regulations require federal agencies with more than 20 vehciles in their fleets to use the devices as well. —Insurance/Uber monitoring dashboard devices let hackers “cut your brakes” over wireless - Boing Boing
