Hint - if you can find it, or the good guys software can find it, the bad guys software can *also* find it and disable the queries. Sure, if www.mcafee.com is really 1234dd432423.wdfasdf241234edre.com, but only till midnite, then you need to look at 3343edrewerwer.13421343.com that's not going to help you get your machine disinfected, is it? Heck - the bad guys don't even need to know how it's generated - they can get a pretty good idea by just tapping into the DNS resolver library and looking for obfuscated names they don't fast-flux themselves. Just tossing out www.anything, mail.anything, and maybe 3-4 others, and you're looking at a pretty damned good filter for the good-guys fast-flux sites.
