OSX Trojan OSX.Trojan.iServices.A Evolves

As reported by Intego in an alert, the Mac OS X Trojan originally found in iWork 09 has now been identified in an illegal copy of Photoshop CS4 circulating on the P2P networks. This is a new version of the original OSX.Trojan.iServices.A, so it has been named OSX.Trojan.iServices.B. It is found bundled with Adobe Photoshop CS4 and while the installer is clean, the Trojan horse is sitting in a crack application that serializes the application.

The Trojan, while not hiding in the installer, seems to have evolved as it will randomly changed its name after installation. The goal of the Trojan is always the same, use infected computer as basic task force to send DOS attack on defined servers. If you use software originating from reliable sources, you should not care about such problems, however, if you are testing /recovering applications (freeware, shareware or trial version) from P2P networks you might have to think twice and be aware of the potential dangers.
