  1. If your Bluetooth-enabled device, such as your cell phone, is in discoverable mode, it's open to use by other Bluetooth devices. There are two ways that your Bluetooth signal can be used without your permission:

    • Bluejacking: This is when someone uses your Bluetooth signal to send you an anonymous and unsolicited text message. The term is derived from "Bluetooth" and "ajack," the username of the person who discovered this ability.
    • Bluesnarfing: A person also can manipulate your Bluetooth signal to gain access to your device and change or steal information stored on it. They may even take over your phone to make calls or send messages.
