Bluetooth attacks are a hidden danger, occurring most often in stores and malls. The main Bluetooth attacks are bluejacking which sends unsolicited messages, bluesnarfing which steals information, and bluebugging which exploits a lack of awareness. To prevent these "blue-T-attacks", users should turn off Bluetooth when not in use, update devices regularly, and change passwords if anything suspicious is noticed. While Bluetooth has benefits of low cost and power, security issues must be addressed for it to have a positive future.
