Duqu, a remote access Trojan (RAT) had been a topic to be discussed recently by lots of security experts especially the ones from Malware Research field and Antivirus Field. Situation got worse after someone had discovered that there is a Windows Kernel vulnerability that associated with Duqu.
How bad is this vulnerability?
This vulnerability only occurred during the processing of True Type Fonts (TTF) and it is pretty bad according to Microsoft:
The attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
If you did not understand what those security experts is trying to say, let me quote it with my words.
If somehow you have this vulnerability from somewhere, you are somewhat screwed because in short, they are going to take control of your computer. 😉

Microsoft and many antivirus company in this world are aware of this and everyone is trying to protect the users or their customers from being infected. As long as you keep up to the latest news, you should be more or less safe I would say.
From Microsoft, they had not released a patch to fix this issue yet. However, they had released a quick fix where it will temporarily disable the support for TTFs but the drawback is, it will prevent any application that make use of TTFs to render properly.
As for Kaspersky, they are simply just ready for it. Ensure that your Kaspersky Cloud Protection is up online and you always update your Antivirus definition. Last but not least, subscribe to this blog if you want to get the latest information to stay safe and secure.
