Hands-on: Blue Hydra can expose the all-too-unhidden world of Bluetooth

http://arstechnica.com/information-technology/2016/09/hands-on-blue-hydra-can-expose-the-all-too-unhidden-world-of-bluetooth/

        Despite their "Low Energy" moniker, BTLE devices are
        constantly polling the world even while in "sleep" mode. And
        while some Bluetooth devices use randomized media access
        control (MAC) addresses, they advertise other data that is
        unique to each device, including a universally unique
        identifier (UUID). As a result, if you can tie a specific UUID
        to a device by other means, you can track the device and its
        owner. By using the Received Signal Strength Indication
        (RSSI), you can get a sense of how far away they are.  That
        information can be used, for good or ill, to generate movement
        data about the people who carry those devices--and to watch
        for devices that appear when they shouldn't. "I have an alert
        set up for when my mother-in-law's car pulls into range,"
        Pwnie's Rick Farina told Ars, as he gave us a walk-through of
        the tool. "It gives me about a 30-second warning."

The correct term is "Internet" NOT "internet" -- please don't 
fall into the trap of using the latter. It's just plain wrong!
