Microsoft should have integrated EMET into Windows 8, and they should have it as an optional update either in the next Win7 SP or during a Patch Tuesday.	dayglo 5 Posts

It's nice to know that we don't have to wait for EOL on Windows XP to keep enjoying the love.	dayglo 57 Posts

Suspicious that the fix is in the current cycle. Says that the actor here knew the vuln was about to be patched, that it's value therefore had dropped to "throwaway," and they used it for targets where the risk of discovery was high. Same is true of CVE-2013-1690 that the FBI used to unmask TOR users. The patch was already in the general Firefox distribution when the exploit was deployed against the not-yet updated TBB derivative Firefox.
