Pirated copies of iWork 2009 carrying malicious software

According to MacRumors.com, there has been a security alert issued concerning pirated copies of Apple’s iWork ’09 software that has been in circulation around the bit torrent sites.  The trojan, OSX.Trojan.iServices.A, allows an unwelcome user to connect to the infected computer and do things such as control certain functions on the computer as well as download additional software.  According to the article, over 20,000 people have downloaded the illegal torrent file and are likely infected if they have installed it.  These are the steps that MacRumors.com recommends for getting rid of the trojan at this point:

 

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

The fact that there is now a virus for the Mac is not that surprising considering that all computer systems are vulnerable.  There have been lesser known trojans on the Mac but they have affected relatively few users and have mostly relied on social engineering methods to get the users to download and install the software – which, of course, this does as well – so as long as you haven’t pirated iWork 2009, you should be fine.
