According to an article on MacRumors: “On the evening of the [February] 13th, an unknown user posted an external link to a file on MacRumors Forums claiming to be the latest Leopard Mac OS X 10.5 screenshots … The resultant file decompresses into what appears to be a standard JPEG icon in Mac OS X but is actually a compiled Unix executable in disguise.

The article goes on to report that “An initial disassembly … reveals evidence that the application is virus-like or was designed to give that impression” but points out that it is more Trojan- than virus-like. The most recent research reveals that the malware however you want to classify it “does send itself to other users in your AIM/iChat buddy list.” Is this the beginning of the end for the virus free OS X world?
