 Mode 3 is the built-in security offered by Bluetooth. In this mode a device can‟t even
connect unless it obtains permission. A link key or PIN code is used to authenticate the
identity of another device.

Common Bluetooth security issues

There are a number of ways in which Bluetooth security can be penetrated, often because there is
little security in place. The major forms of Bluetooth security problems fall into the following
categories:

Bluejacking:

Bluejacking is a hacking method that allows an individual to send anonymous messages to
Bluetooth-enabled devices within a certain radius. First, the hacker scans his surroundings with a
Bluetooth-enabled device, searching for other devices. The hacker then sends an unsolicited
message to the detected devices. Bluejacking is also known as bluehacking.

Bluejacking exploits a basic Bluetooth feature that allows devices to send messages to contacts
within range.
Bluejacking does not involve device hijacking, despite what the name implies. The
bluejacker may send only unsolicited messages. Hijacking does not actually occur because the
attacker never has control of the victim‟s device. At worst, bluejacking is an annoyance.

Bluebugging:

Bluebugging is a technique that allows skilled hackers to access mobile commands on Bluetooth-
enabled devices that are in discoverable mode. Because discoverable mode is a default setting,
most Bluetooth-enabled mobile phones and devices are automatically vulnerable to bluebugging
