Thank you Weil. And to add, a new variant of MAC Guard is already in the wild that defeats measures put into place with the latest Security Update. I'm well versed in social engineering methods; in fact, these are the same methods used by much of the current Windows malware that exists. To add, I've held various positions on my local MUG for the past ten years, have done presentations on numerous Mac-related topics over that time, have helped many local Mac users with software and hardware-related issues, and have volunteered my time in these forums for the past eight years helping Comcast users with their Mac-related service issues when they couldn't find information anywhere else, so if you want to question my knowledge that's your right I suppose, but I'm not some dummy who reads the tech blogs and simply copy/pastes what I read here. We've known this day was coming and if you go back in my posting history you'll find that I've warned of its coming. Keep your head in the sand all you like, but I guarantee you, this is just the beginning.
That being said, no OS will ever be entirely secure. Windows made steps a while back in regards to the ActiveX issues. MS has also tightened up security in other areas to substantially restrict the damage a user can inflict on himself. However, people still can be fooled. Mac OS, on the other hand, for years has been quite lax on their attitude towards security. However, every year at events like Black Hat, the first OS to fall is usually Mac OSX. Rather quickly I might add. This latest security update is a good first step at protecting users against themselves. However, it also shows how quickly the bad guys are at work exploiting vulnerabilities in the OS and finding new ones. It also shows why the days of flying without some type of protection (I recommend at least Little Snitch and one of the free AVs) are over.
