A few days ago, [Ben Caudill] of Rhino Security was scheduled to give a talk at DEFCON. His project, ProxyHam, is designed for those seeking complete anonymity online. Because IP addresses can be tied to physical locations, any online activities can be tracked by oppressive regimes and three letter government agencies. Sometimes, this means doors are breached, and “seditious” journalists and activists are taken into custody.
With the ProxyHam, the link between IP addresses and physical locations is severed. ProxyHam uses a 900MHz radio link to bridge a WiFi network over miles. By hiding a ProxyHam base station in a space with public WiFi, anyone can have complete anonymity online; if the government comes to take you down, they’ll first have to stop at the local library, Starbucks, or wherever else has free WiFi.
[Ben Caudill] will not be giving a talk at DEFCON. It wasn’t the choice of DEFCON organizers to cancel the talk, and it wasn’t his employers – [Ben] founded and is principal consultant at Rhino Security. The talk has been killed, and no one knows why. Speculation ranges from National Security Letters to government gag orders to a far more pedestrian explanations like, “it doesn’t work as well as intended.” Nevertheless, the details of why the ProxyHam talk was cancelled will never be known. That doesn’t mean this knowledge is lost – you can build a ProxyHam with equipment purchased from Amazon, Newegg, or any one of a number of online retailers.

And now PROXYGAMBIT:
http://samy.pl/proxygambit/
ProxyGambit is a simple anonymization device that allows you to access the Internet from anywhere in the world without revealing your true location or IP, fracturing your traffic from the Internet/IP through either a long distance radio link or a reverse tunneled GSM bridge that ultimately drops back onto the Internet and exits through a wireless network you're no where near.
While a point to point link is possible, the reverse GSM bridge allows you to proxy from thousands of miles away with nothing other than a computer and Internet with no direct link back to your originating machine.

Next month during the Def Con hacker conference in Las Vegas, security researcher Ben Caudill will unveil a potentially game changing device called a ProxyHam. Without question, the promise of ProxyHam should leave proponents of Internet privacy and anonymity beyond excited. By relying upon a 900 MHz radio connection, Caudill’s device effectively serves as a long-distance Wi-Fi router. Specifically, the ProxyHam can transmit a Wi-Fi connection up to a distance of 2.5 miles in ideal conditions. As a result, even in scenarios where authorities manage to track down a target’s Internet connection, they might arrive on the scene (presumably a location with public w-fi access) only to find a ProxyHam device transmitting a low level signal perhaps thousands of feet away in any direction.
