New zero-day Windows kernel vulnerability associated with Duqu Trojan !!!

[INDRANIL]

In the continuing saga of the malware known as Duqu, CrySyS Lab at the Budapest University of Technology and Economics has announced it was able to acquire a copy of the "dropper" from one of the victims. Droppers are typically very small, are designed to evade detection by anti-virus and can sometimes contain exploit code used to inject themselves onto the target computer.

That is why this finding is important. Many analysts still have some doubts as to the relationship between Duqu and Stuxnet, but this piece of the chain of infection was missing. Now with a sample of the missing piece, we can put together a more coherent picture.

What is a dropper and what does this mean? A dropper is a term used by anti-virus researchers to denote a piece of code that is usually installed onto a computer to download further malicious components.

The dropper acquired by CrySyS used a Microsoft Word document that targets a zero-day vulnerability in the Windows kernel.

This is an important distinction, as the vulnerability is not in Microsoft Word itself, meaning this flaw could be exploited through other delivery mechanisms.

Microsoft has stated it is diligently pursuing a fix for the vulnerability used by this malware and hopes to provide it as soon as possible.

Open your eyes and always be careful . Umm probably you should wait for the Microsoft fix . Have a nice day .

Welcome Bear . Very much busy with the daily schedule . Trying to fix that schedule as a flexible one .

I'd appreciate if someone can provide me more information on the dropper and it's delivery mechanisms because I were to assume it's the same common delivery mechanism, I believe you can still defeat this though denying the initial execution of the dropper. Otherwise,you may block it's outbound connections in the hope to stop it from downloading further malicious components.
