Hackers Control Trojan Worm Via P2P

Just when you thought you’d seen everything P2P is useful for. A recently discovered Internet worm, “Nugache-A” is spreading widely via AIM as ell as MSN Messenger.

In and of themselves, new internet worms pop up too frequently to be news anymore. What is significant about this worm is the way in which it can be remotely controlled, via P2P.

The command and control channel technique used by the worm is exceptionally different. The worm connects to infected peers, the bots then talk to each other via port 8/TCP over an encrypted P2P channel.

Using peer to peer technology in botnets such as this isn’t entirely new, but the quality of such uses appears to be improving. Fifty bucks for anyone who can figure out how to attach P2P to something both sinister and new.

A peer-to-peer (or P2P) computer network relies primarily on the computing power and bandwidth of the participants in the network rather than concentrating it in a relatively low number of servers. P2P networks are typically used for connecting nodes via largely ad hoc connections. Such networks are useful for many purposes. Sharing content files (see file sharing) containing audio, video, data or anything in digital format is very common, and realtime data, such as telephony traffic, is also passed using P2P technology.A pure peer-to-peer network does not have the notion of clients or servers, but only equal peer nodes that simultaneously function as both "clients" and "servers" to the other nodes on the network. This model of network arrangement differs from the client-server model where communication is usually to and from a central server. A typical example for a non peer-to-peer file transfer is an FTP server where the client and server programs are quite distinct, and the clients initiate the download.
