While Google solves their problems, Mac OS X, with it’s new 10% market share, gets it’s first malicious trojan. iServices.a came to the attention to the technological community through Intego which reports that copies of iWork ‘09 pirated through bittorrent
like this one contains a trojan that “is installed as a startup item (in /System/Library/StartupItems/iWorkServices, a location reserved normally for Apple startup items), where it has read-write-execute permissions for root. The malicious software connects to a remote server over the Internet; this means that a malicious user will be alerted that this Trojan horse is installed on different Macs, and will have the ability to connect to them and perform various actions remotely. The Trojan horse may also download additional components to an infected Mac.”

It’s x86 disassembly code can be found here. (Alternate download site)

A variation of this virus was also found in pirated copies of Adobe Photoshop CS4. This version is called iServices.b.
…Looks like it’s time for you to get Mac antiviral/security software; it’s coming.
