Live attackers or blind worms? (was Re: Country of Origin for Malicious Attacks)

Since the birth of CodeRed II and Nimda in Fall 2001, web/IDS logs have constantly been filled with steady influx of IIS-based attacks. I remember a site was set up for people to report IP's of attacking boxes infected with such worms. Having seen such log entries piling up fast and nonstop for the past 22 months, I often wondered that they could serve as a good cover for directed, covert attacks by real persons/groups. This posting might not be a qualified topic for this list - my apologies. Bill
