Hiding Packets in VoIP Chat

holy_calamity writes "Two Polish researchers say they have developed a system to hide secret steganographic messages in the packets of a VOIP connection. It exploits the fact that VoIP uses UDP, not TCP; it is designed to tolerate some packets going missing -- so hijacking a few to transmit a hidden message is not a problem."

If somebody's looking for something encrypted data is something. With this method, there isn't anything to find, unless I'm totally misunderstanding it.

Viruses will be the next safe transmitters

I think the future will see the use of trojan/virus techniques to send data. It's already been fairly well proven that stopping botnets is next to impossible given current technologies, attitudes and ideas on the part of administrators and engineers, and most importantly that AI bears not a candle compared to Natural Stupidity.

Forget just VoIP. In the future we'll hide communications networks under multiple layers of encryption inside trojan'd everything that is awfully hard to tell innocent user data from something else. We'll probably also host websites and files that way in a coalescence and then expansion of BT/P2P and anonymous remailer methods but not so much with identifiable clients but instead viral ware that people choose to allow on their machines so as to prevent privacy invasion by government and business.
