Flash 0-Day Exploit Used by Angler Exploit Kit
The "Angler" exploit kit is a tool frequently used in drive-by download attacks to probe the browser for different vulnerabilities, and then exploit them to install malware. The exploit kit is very flexible and new exploits are added to it constantly.
However, the blog post below shows how this exploit kit is currently using an unpatched Flash 0-day to install malware. Current versions of Windows (e.g. Window 8 + IE 10) appear to be vulnerable. Windows 8.1, or Google Chrome do not appear to be vulnerable.
This is still a developing story, but typically we see these exploits more in targeted attacks, not in widely used exploit kits. This flaw could affect a large number of users very quickly. Please refer to the original blog for details.

Update: "... tested it against the free version of Malwarebytes Anti Exploit* (a product from one of my customers). That stopped it. Well done!..."

It's sleep time here, but anyone else want to take a stab?

Pps
Presumably the chrome pepper flash plugin is harder to exploit (and is possibly partially sandboxed, and if I recall correctly auto updates without chrome having to necessarily)

>if I recall correctly [chome] auto updates [the flash plugin] without chrome having to necessarily
to correct myself, that's probably incorrect (chrome sys update, not just the flash plugin itself)

in any case I digress, given >Chrome’s version of the Flash Player plugin is sandboxed, mitigating potential effects to end users.

I have just updated my main Windows 7 SP1 x64 build laptop today and will run a few tests to see if I get any issues.
