Apple's OS X has always been positioned as a juicy target even though it's market share is almost non-existent compared to Microsoft's domination. And while converting iPod customers into MAC users hasn't shown any progress so far and I doubt it would, malware authors are as always actively experimenting or diversifying the threatscape. One question remains unclear, why would someone want to own a MAC, compared to owning hundreds of thousands of Windows PCs out there? To me, it's not about achieving the scale necessary for a Botnet, rather, experiment, show that it's possible through POC releases, or basically start attacking the living in a safe heaven until for now, MAC users.
Recently, an OS X trojan appeared, second (nice attitude from Apple on embracing the inevitable!), one followed, and besides "worming" a vulnerability and experimenting with propagation methods, I don't really think it's the big trend everyone is waiting for, a standard POC(Cabir), whose core function would empower a generation of variants for years to come.
I just came across this from Trifinite's blog :
"Trifinite.group member Kevin has published a paper detailing the techniques he used in the development of the InqTana Bluetooth worm that targets vulnerable Mac OS X systems. There has been significant confusion surrounding this worm, so here are some salient points:
- The concurrent release of the OS X Leap.A and InqTana.A worms is coincidental
- There is no conspiracy, AV vendors and Apple were notified about Kevin's progress in developing this worm in advance of making details publicly available
- Both 10.3 and 10.4 systems are vulnerable until patched with APPLE-SA-2005-05-03 and APPLE-SA-2005-06-08
- InqTana prompts before infecting *by design*, Kevin was just trying to be nice, but the worm could easily spread silently
Kevin's paper is available at http://www.digitalmunition.com/InqTanaThroughTheEyes.txt. Comments can be directed to the BlueTraq mailing list. Our sympathies to those organizations who were affected by the false-positive signatures published by overzealous AV companies."
It clarifies a lot I think, mostly that, while architecture and OS popularity have a lot to do with security and incentives for attacks, "InqTana.A itself has absolutely nothing to do with Leap.A. My work was done completely independent of the author of Leap. The day after I sent out queries to the AV companies about my code I was shocked to see another OSX worm had already been in the news. While my worm sat in the mail spools of several AV companies they were busy writing about the "First Trojan/Worm for OSX"."
Leakage of IP, or I'm being a paranoid in here? Wired also has some nice comments.
