from macrumors.com On the evening of the 13th, an unknown user posted a link to a file on MacRumors Forums claiming to be the latest Leopard Mac OS X 10.5 screenshots. The file was named "latestpics.tgz" The resultant file decompresses into what appears to be a standard JPEG icon in Mac OS X but was actually a compiled Unix executable in disguise. An initial disassembly (from original discussion thread) reveals evidence that the application is a virus or was designed to give that impression. Routines listed include: _infect: _infectApps: _installHooks: _copySelf: The exact consequences of the application are unclear, but according to the users that originally executed the application have noted that it appears to self propogate:If anyone remembers last night, when lasthope spread that picture that opened in terminal. I just turned on my other computer and it said it had an incoming file, from my computer, which was the latest pics file. Any help. I have already secure deleted it off of my harddrive, but how do i know that it will not come back. Andrew Welch who had done some of the initial disassembly is posting updates to this thread. According to the initial investigation, the application does use Spotlight to find the applications on the machine and subsequently insert a stub of code into each application executable.
