I'm baffled by this headline: "BitTorrent copies of iWork '09 may contain nasty Trojan"
What? This is news? To me, this sounds like "Software downloaded from porn sites may contain viruses". It should be fairly obvious that the principle of caveat emptor doubly applies to black-market items. Obvious enough that this doesn't make all the major news sites.
In addition, I didn't think that the major Mac demographic included a lot of torrenters. Most Mac owners are rich enough that they can blow $80 on new software. I do realize that there are exceptions (in fact, I am one of them), but I didn't realize that this was that popular.
