When thinking like a bad guy with the goal of distributing any number of covert communications to any number of recipients, there are a number of critical attributes which should be present. The message should: Be portable and self-sustaining. Be able to be propagated without the originator actually having to *own* the message or carry it on him. Have the ability to control which recipients receive/can read the message. Have the messages backed up and managed by a 3rd party in perpetuity. Be free Be able to be received without any privileged access to equipment or require specialized equipment to receive. Be detection resistant, or even detection PROOF. This session will be about how to go about just that. ALL of these attributes will be satisfied, and I will illustrate how you can literally have a detection-proof covert communication. I dont think Ive ever said that before, and just writing the words detection-proof makes me cringe just a bit. But Ive racked my brain on a way to detect what Ill show you and I cant find a way to do it. That will be the other cool part of this talk well all brainstorm at the end on a way to detect this. I bet you cant. :) To me, this is the epitome of what DEF CON is about, and I hope youll join me at this talk. Besides, my super-hot wife will be there. Get hammered at Hammer of God!!!
