Bluejacking is the name given to the transfer between Bluetooth-enabled devices.
Bluejacking can be used for transferring messages and images between Bluetooth-enabled devices - smartphones, cell phones, tablets, PDAs. The transmission can take place at distances of about 10 meters. These transmissions are made using Object Exchange( OBEX) over the Bluetooth network, without the involvement of a network operator. This means that there are no transmission costs.
In Bluetooth networks, Bluetooth devices can be configured by users to be accessed and not accessed. In addition, there is also the possibility to search for Bluetooth-enabled devices. Bluejacking is a legitimate application, but it can also lead to the less harmless bluesnarfing; namely, attacks that involve data theft.
