Botnet Generated Spam
Botnets are networks of compromised machines that are under the command and control (C&C) of one entity - the botnet master. They are typically used for crimes such as denial-of-service attacks, identity thefts, phishing and, most commonly, for sending spam. Current botnets have easy-to-use HTML-based interfaces and can be rented out by spammers for their various spamming campaigns. Researchers reported that during 2008, 85% of spam was generated by six botnets (Mega-D, Srizibi, Storm, Rustock, Pushdo and Cutwail). (Nov 06, 2009)
