Sturdier botnets mean more spam in 2007


If a control server is shut down, the spammer can easily update the rest of the bots with the location of a new server as long as he controls at least one bot in the net.

Assembled by a Trojan called SpamThru, the new botnets are tougher to bring down, says Paul Wood, senior analyst with MessageLabs, a message security and filtering service. "The advent of Trojans like SpamThru makes it possible for each bot in the net to learn about the location of other bots. When a bot goes down or the command and control channel is compromised, the other bots know about it." Sturdier botnets mean more spam in 2007 - Security - www.itnews.com.au
