Bluebugging

Bluebugging allows skilled individuals to access the mobile phone commands using Bluetooth wireless technology without notifying or alerting the phone’s user. This vulnerability allows the hacker to initiate phone calls, send and read SMS, read and write phonebook contacts, eavesdrop on phone conversations, and connect to the Internet. As with all the attacks, the hacker must be within a 10 meter range of the phone. This is a separate vulnerability from bluesnarfing and does not affect all of the same phones as bluesnarfing.
