Researchers from three U.S. institutions presented a paper highlighting the recent evolution of peer-to-peer botnets. Most botnets use a centralized command-and-control structure based on IRC. P2P botnets have no centralized control point, making them much harder to detect and shut down. The researchers chose the botnet implanted by the Storm worm, Trojan.Peacomm, for their case study. The botnet uses the Overnet network, which implements the Kademlia algorithm. Index poisoning was first mooted as a way of stopping exchange of copyrighted files.”]
