A pirated version of iWork '09 linked on The Pirate Bay allegedly contains a Trojan Horse called "iWorkServices."
Some have claimed that iWorkServices is a legitimate part of the software designed to interface to the forthcoming iWork.com online service. I looked at Activity Monitor while running retail copies of Pages '09 and Numbers '09 and didn't see an entry for iWorkServices.
If you have installed the pirated version of iWork '09, first, shame on you. Second, one commenter claims that the trojan can be removed by following these instructions:
1) (open Terminal.app) 2) sudo su (enter password) 3) rm -r /System/Library/StartupItems/iWorkServices 4) rm /private/tmp/.iWorkServices 5) rm /usr/bin/iWorkServices 6) rm -r /Library/Receipts/iWorkServices.pkg 7) killall -9 iWorkServices
Calls to Apple to confirm have not been returned.
