With some basic skills and a couple hundred bucks, you can build your own Bluetooth rifle, just like the guys at Flexilis.The reaction of the Bluetooth SIG (Special Interest Group)?
We will also interview the Flexilis staff on what their custom software is capable of doing. As John Hering says, "Our goal is to make the public more aware of wireless security issues and bad policies. Bluetooth is wide open and most people have no idea what can be done to their devices."
If they are concerned about that their device is vulnerable to security threats, check with manufacturers and possibly request a software upgrade to a version without vulnerabilities. Following this advice, they are in no more danger of exposure by a long range antenna than with a normal range hacking device. As a general rule, we also recommend that users not keep confidential information on mobile devices since the most common security threat is actually the many thousands of devices stolen or lost every day across the globe.So you can't say you haven't been warned.
