Explanation:
A bluejacking attack is where unsolicited messages are sent to mobile devices using Bluetooth.
Bluejacking is the sending of unsolicited messages over Bluetooth to Bluetooth-enabled devices such as
mobile phones, PDAs or laptop computers, sending a vCard which typically contains a message in the
name field (i.e., for bluedating or bluechat) to another Bluetooth-enabled device via the OBEX protocol.
Bluetooth has a very limited range, usually around 10 meters (32.8 ft) on mobile phones, but laptops can
reach up to 100 meters (328 ft) with powerful (Class 1) transmitters.
Bluejacking is usually harmless, but because bluejacked people generally don't know what has happened,
they may think that their phone is malfunctioning. Usually, a bluejacker will only send a text message, but
with modern phones it's possible to send images or sounds as well. Bluejacking has been used in guerrilla
marketing campaigns to promote advergames.
