Bluetooth headsets are all the rage these days. But I guess in the frenzy of the handsfree mania we forgot what cellphone manufacturers warned us about when they first introduced the technology- Bluetooth can potentially leave your device more vulnerable to virus attacks. Though such cases never really reached the epidemic level that the computer viruses did, it did lead to the evolution of a new form of hacking which can aid intruders to tap into your device and eavesdrop on your conversations and even record it. SANS Institute author and senior instructor Joshua Wright has researched extensively on the matter and has found that ‘Bluetooth headsets can be exploited granting a remote attacker the ability to record and inject audio through the headset while the device is not in an active call.’ Now, that’s something that really is a cause for concern. Watch Joshua Wright demo his research in the video.
