Is That A Network In Your Pocket, or Are You Just Happy To See Me?
I practically carry my own network in my pants these days with all the gadgets I use (multiple devices with WiFi and/or bluetooth capabilities). Anyway, as I’ve been using bluetooth more and more to keep them all connected, I ran across this document discussing some of the vulnerabilities in bluetooth, in particular some implementations used in cellphones. Worth reading if you use Bluetooth yourself.
Best advice…. shut that bluetooth down when not in use.
Some additional (more technical) info is available in a report done by @stake [PDF].
