Google Researchers Find Wormable "Crazy Bad" Windows Exploit

There are probably similar bugs in most AV solutions. For me the big question is are they are discovered and reported to vendor or kept secret and being used for other purposes?

 

Yup, seems like all AV's may have big holes, and Win Def isn't any different. I suppose most of these bugs are probably being used for targeted attacks.

 

As Travis pointed out, the WD engine has a huge footprint which is what makes it vulnerable. Whereas that also might be the case for some third party AVs, it is not the case for all. Eset's for example is modularized with those modules loaded in kernel space. This reduces Eset's kernel footprint considerably, making it less vulnerable.
