Bluetooth: A wireless technology standard used for exchanging data between fixed and mobile devices over short distances. It utilizes short-wavelength UHF radio waves and is primarily designed for low power consumption. Bluetooth has become a common feature in many types of hardware, from computers and smartphones to audio equipment and car audio systems. Like any wireless technology, it has potential vulnerabilities and can be exploited if not properly secured, such as in the case of Bluejacking or Bluesnarfing.
