I Don't know about the malware issue, but this guy certainly did not  
get his Ph.D in the use of the English language !

Two Mac trojan outbreaks were spotted in the past week leaving several  
people, including myself, to wonder if the tipping point for the Mac  
malware epidemic has arrived. Frankly, I don't know, but I tend not to  
think so. I do think, however, that Mac malware will now become  
endemic amongst the high-risk groups such as file-swappers.

This past week a trojan claiming to be the latest iWork release was  
spotted on file sharing networks. Shortly thereafter, a similar trojan  
was sighted that masquerading as a crack for Photoshop CS4. Both  
events are making some people question whether or not the Mac's long  
tenure as being a malware-free system is coming to a close and to face  
facts and install AV software.

The short answer is if you are a relatively well-behaved computer  
user, probably not. Mac malware is not endemic amongst the general  
population due to these events. The trojans of the past week is not  
self-propagating beyond the high-risk population, namely file  
swappers, and is relatively easy to find, analyze, and remediate. This  
is in stark contrast to PC users who have been hit with the Downadup/ 
Conficker worm, which propagates via three orthogonal vectors and  
includes one remote exploit, and actively prevents you from visiting  
websites that contain remediation tools.

I do think the relative halcyon days of malware-free Macs are coming  
to an end. Anyone who is currently infected by the new malware will  
remain infected without direct human interaction due to the lack of  
any automatic mechanism for the identification and removal of malware.  
That means there is a non-zero population of Mac users who are now  
compromised and will remain compromised unless they either clean their  
machine or they buy a new system. Sounds familiar, right?

The question I want answered is whether or not the monetization rate  
of compromised Macs is sufficient for the malware authors to continue  
to pursue the platform. If not, these events will be a blip on the  
radar; otherwise, Mac owners better keep their Time Machine backups up  
to date.
