I have a box on my desk that your CDMA cell phone will automatically connect to while you send and receive phone calls, text messages, emails, and browse the Internet. I own this box. I watch all the traffic that crosses it and you don't even know you're connected to me. Welcome to the New World, where I, not them, own the towers. Oh, and thanks for giving me the box... for free.
This box is a femtocell, a low-power cellular base station given or sold to subscribers by mobile network operators. It works just like a small cell tower, using a home Internet connection to interface with the provider network. When in range, a mobile phone will connect to a femtocell as if it were a standard cell tower and send all its traffic through it without any indication to the user.
The state-of-the-art authentication protecting cell phone networks can be an imposing target. However, with the rising popularity of femtocells there is more than one way to attack a cellular network. Inside, they run Linux, and they can be hacked.
During this talk, we will demonstrate how we've used a femtocell for traffic interception of voice/SMS/data, active network attacks, and explain how we were able to clone a mobile device without physical access.
