There's been serious malware on the mac for ages.
You have to be doing some really stupid things to get it, e.g. illegally downloading software, several porn sites do it, etc.,
It looks as if it's now requiring much less stupidity to get malware on the mac, but that's really all that's changed. Email scams are now considering the fact that I might be using a mac.
Yesterday I spent several hours going through discussions.apple.com and collecting requests for help from Mac users who have been affected by this issue.

It started with four posts on April 30; this past weekend there were 42 unique, new discussion threads on this subject.
I am not unfamiliar with Apple’s forums. I’ve done similar searches in the past, especially after reading some of those same posts that Gruber called out from 2008. I have never found more than one or two in-the-wild reports. This time, the volume is truly exceptional.

I went to the forums and searched for Mac Defender, Apple Security, and Mac Protector and found a few dozen posts. Plenty of people posting straightforward solutions.
