Definition - What does Bluejacking mean? Bluejacking is a hacking method that allows an individual to send anonymous messages to Bluetooth-enabled devices within a certain radius. First, the hacker scans his surroundings with a Bluetooth-enabled device, searching for other devices. The hacker then sends an unsolicited message to the detected devices.
Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs).luetooth uses the microwave radio frequency spectrum in the 2.402 GHz to 2.480 GHz range. Maximum power output from a Bluetooth radio is 100 mW for class 1, 2.5 mW for class 2, and 1 mW for class 3 devices.
