The original ProxyHam talk was also set to be accompanied by the sale of ProxyHam devices that could have enabled purchasers to conduct the wireless proxy attack at their leisure. Speculation around why the ProxyHam talk was cancelled involved theories that the Federal Communications Commission got the talk cancelled, though that has never officially been confirmed or denied.
While the ProxyHam talk was cancelled, it has been replaced, by a talk set to be delivered at 4 p.m. PT at DefCon and titled “HamSammich—long-distance proxying over radio” in which security researchers Robert Graham, CEO of Errata Security, and David Maynor, chief scientist at Bastille Networks, will reveal how ProxyHam works and how it can be built using off-the-shelf technology today.
