"This is almost certainly the year of the OS X exploit."
Saying that 2006 will be the year of OS X exploit seems a little wide of the mark. Ok so Mac OS X isn't 100% secure but is there a modern GUI-based OS that is? Let's not beat about the bush here this is the DECADE of the Windows exploit. For once we have a situation where Windows is ahead of OS X. Spyware and Viruses have been a 'feature' of Windows since the early days of the internet.
A key point that is mentioned in this article is that OS X has inherent security from the ground up that doesn't exist in Windows. Windows runs as administrator by default and all rights are granted to the user without the need to enter an admin password. Being UNIX based OS X always requires a password for a user to install any new applications. Also Microsoft really screwed up with ActiveX allowing it far too many rights and hence opening holes which hackers could use. OS X does not support ActiveX. Finally, Windows is a clear market leader and as such there are more hackers with Windows PCs, hence there are more viruses and hacks for Windows. That will change as OS X gains market share.
"This is almost certainly the year of the OS X exploit." - I remain a sceptic.
