Bluebugging was next after bluesnarfing; initially bluebugging targeted mostly laptops, but with the increased advances being made in cellular phones and PDAs, the incidents of mobile bluebugging has heightened manifold.
Bluebugging is an attack which allows an unauthorized person to listen in on calls made from and to a victim’s phone. At first, bluebugging was limited to merely listening in and as an extension, recording these conversations, but has now progressed to being able to manipulate the various functions of the phone. For example, an attacker can use a victim’s phone to make calls, send messages, in effect carry out any task that the phone can do.
A program called Blue Bug was released earlier, where bluebugging was made possible, and easy. Again, as with bluesnarfing, the vulnerabilities of phones have decreased with subsequent releases of Bluetooth technology. However, there are still some basic safeguards one can take: use Bluetooth judiciously, and not in crowded areas. It is unwise to allow strangers to handle mobile phones, as this could give them an added access to the phone. It is important to be very aware of the files that are being relayed to the phone; there is a great risk of receiving malware via Bluetooth.
