What a Mac malware attack looks like


Well, that didn’t take long.
After I posted my analysis of why the time is right for bad guys to begin attacking the Mac in earnest, I heard from two readers who had encountered in-the-wild attacks on Macs in their respective workplaces. In both cases, the results showed up via Google Image Search. (This is an increasingly common source of malware, as security researcher Brian Krebs points out in a well-timed blog post today.)
I was able to duplicate these results and encountered an identical attempt from this same campaign to convince me to install a rather nasty Trojan on a Mac. (Sophos has an analysis of what this particular species does.) I uploaded the sample—a Mac installer package in a Zip file—to Virustotal.com, which confirmed that it is indeed the same code.
