"After five months, we have finally seen a switch at the top as W32/Yaha.E surpasses Klez securing the pole position," said Steven Sundermeier product manager at Central Command, Inc. W32/Yaha.E arrives with a randomly selected subject line likely associated with a love or friendship based theme. It spreads itself through email, as well as, by exploiting holes in MSN Messenger and ICQ instant messaging. "Peer-2-Peer networks like ICQ and MSN Messenger in conjunction with file sharing networks like Napster and KaZaa are beginning to play a pivotal role in the distribution of this latest breed of viruses in 2002."
Other worms targeting file sharing networks for the month of August include: Worm/P2P.Duload.A, Worm/P2P.Sambud.A, Worm/P2P.Sambud.B, and TR/Bat.Dolomite. A complete list can be read at: (www.centralcommand.com/virus_descriptions.html).
