As more personal, mobile electronic devices are equipped with the Bluetooth technology for shortrange wireless, users of these devices often unknowingly have them enabled to be discoverable all the time. This can lead to security threats as well as privacy concerns, however most people are not aware of these risks or do not perceive them as issues. In this paper, we highlight some of the vulnerabilities of the Bluetooth protocol and extend the mobile Denial of Service attack to Bluetooth. We have found that currently popular Bluetooth-enabled mobile devices are susceptible to DoS attack, since these devices display pop-up notifications whenever they receive an incoming request. Tracing the exact position of the devices is more difficult due to the high range of Bluetooth sensors, although it is still possible using signal strength.
