In 2011, this exploit kit won't work

And some Web sites will be a lot safer! While reviewing incidents and deobfuscating a Web site today, I discovered an installation of a particular exploit kit that won't work after New Year's Eve.  The site I found caught my attention because the code simply looks like garbage.  As the saying goes, "One man's trash is another man's treasure."  So I started digging into the obfuscation of the code and found something that I thought would be topical considering today's date.  The code in this exploit kit will actually expire at midnight on New Year's Eve local time!  In this post, I'll cover how I came across this and show you how and why the exploit kit installations will expire.

Installation Protection Mechanisms of Phoenix Exploit's Kit
