FTC Warns Consumers: Don't Sync To Your Rental Car! (securityledger.com)

Slashdot reader chicksdaddy quotes an article from Security Ledger: The Federal Trade Commission is warning consumers to beware of new 'connected car' features that allow rental car customers to connect their mobile phone or other devices to in-vehicle infotainment systems. "If you connect a mobile device, the car may also keep your mobile phone number, call and message logs, or even contacts and text messages," the FTC said in an advisory released on Tuesday. "Unless you delete that data before you return the car, other people may view it, including future renters and rental car employees or even hackers."

The Commission is advising renters to avoid syncing their mobile phones to their rental car, or to power devices via a USB port, where settings on your device may allow automatic syncing of data. Consumers who do connect their device should scrutinize any requests for permissions.

Security researchers have also discovered another car-related vulnerability. The software connecting smartphones to in-vehicle "infotainment" systems could also make cars vulnerable to remote attacks.

    So "hackers" is the new "criminals who use some kind of technology"? Or just "who use stuff I don't have no clue whatsoever but insist in using regardless?"

    Seriously, I really, really, really wish you could kill people with a computer remotely. Only then we have at least a minimal chance to get people to actually know what they're doing with their boxes, and some idiots wouldn't be allowed near one because they'd endanger themselves and others.
