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.
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.
This appears to be the first widespread malware attack.
1. AV program catches the attempt, prevents the installation.
2. Much simpler from Apple's perspective: prevent installation from outside the App Store.
"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.
Definitely a nice piece of linkbait.
