Also Known As: OSX/iWorkS-A, OSX/iWorkServ

OSX/IServiceA is an OS X Backdoor that was spread via a trojaned iWork '09 free trial installer shared on peer-to-peer networks [1]. Discovered in early 2009, OSX/IServiceA was one of the first two signatures introduced into XProtect, when silently released as a part of Mac OS X 10.6.0 Snow Leopard [2].
