Summary : This is the story of how someone with very little knowledge of electronics embarked on a project to build a 2.4 GHz wireless development platform and ultimately succeeded in creating a low cost device that can be used for Bluetooth sniffing and more. Find out how to build your own Ubertooth One, how to use it for Bluetooth experimentation and other things, and catch a glimpse of an exciting future of wireless security research enabled by open source hardware. Project Ubertooth was a direct outgrowth of the work Dominic Spill and I presented at ShmooCon V in our talk, Building an All-Channel Bluetooth Monitor. The feedback we received from that presentation led me to pursue development of a low cost hardware platform for Bluetooth sniffing. Ubertooth One brings the hardware cost down from over $1000 to under $100. It can discover non-discoverable devices, sniff complete conversations, and (with future work on firmware) can even be used for raw frame injection. It also has capabilities beyond Bluetooth.
