Abstract:
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 on mobile phones, but
laptops can reach up to 100 meters with powerful transmitters.
Bluejacking
allows phone users to send business cards anonymously using Bluetooth wireless
technology. Bluejacking does not involve the removal or alteration of any data
from the device. Bluejackers often look for the receiving phone to ping or the
user to react. In order to carry out a bluejacking, the sending and receiving
devices must be within 10 meters of one another. Phone owners who receive
bluejack messages should refuse to add the contacts to their address book. Devices
that are set in non-discoverable mode are not susceptible to bluejacking.
