Very strange thing about that Mac botnet, Driftdiver. Nobody has EVER found an infected Mac member of it in the wild! Not even Symantec. . . who subsequently FIRED the two characters who published the article claiming it's discovery in the Virus Bulletin! To this day Symantec reports the virulence of the supposed Trojan that spread the Bot, which was included in a BitTorrent copy of the Trial version of iWork'09 that the torrent sites themselves listed as having only been download fewer than two dozen times before the infection was discovered, as "zero to 49"!!! Despite those bozos claim the bot was "20,000 Macs" large in their artcle. Not one. None. Zip. Nada.
same ole tired argument based on fallacy.
