In an interesting twist on the commonly held view that OSX is much more secure ZDNet has actually done some testing and dispelled a lot of the rumors and replaced them with some cold hard facts.

I guess it goes to show that a lot of the superiority OSX was able to claim in the past came from it's very low marketshare making it a less popular target for exploits, but as that share and awareness has grown it's become a juicier target. Like Flash (which has also been exposed recently as a cause for concern) I hope Apple step up to the plate and make a difference early in 2008.
It's interesting to see how the testing also confirms that Microsoft have done a good job in improving the security of Vista over WinXP - hopefully Service Pack 1 will continue this trend in the right direction.
It's the sort of article that ThinkSecret would have had as front-page news... if Apple had not litigated them to the wall.
