CVE-2013-7331/CVE-2015-2413 (onload variant) and Exploit Kits




Thanks to EKWatcher and his decoding skills saving me a lot of time.

As we can see more and more of those "XMLDOM" checks in  exploit kits i decided to write here some of the checks spotted. This is a fast moving area and it will be hard to keep up to date with this, but this may give an idea of how it's being used.


Magnitude EK:

Won't details as this part of the code has been disparead around end of november 2015 then reappeared in middle of march inside the redirector in front of Magnitude
