When pirated versions of iWork '09 hit the the torrents last week folks soon discovered an added payload in the form of the OSX.Trojan.iServices.A Trojan. Now a new variant, cleverly named OSX.Trojan.iServices.B, is affected more pirated Mac software. According to security firm Intego the new Trojan is targeting versions of Adobe Photoshop CS4 and comes in the crack program users run to be able to use the pirated version of the software. The Trojan installs a backdoor, then requests an administrator password and starts the backdoor application with root privileges. It also makes contact with a pair of IP addresses which means someone out there will know when the malware is installed and could possibly download additional software to the infected Mac.
