Two Worm "Families" Make Up Most Botnets

JMoon writes "HNS has an article about the Sdbot and Gaobot families which are responsible for most botnets worldwide. These two families were responsible for 80 percent of detections related to bots during the first quarter of 2007. Other culprits, although on a much lesser scale, included Oscarbot, IRCbot or RXbot."
