Microsoft Excel.WsF : New houdini

We know the infection Houdini – Dinihou everyone call “USB shortcut Virus.”
A new variant begins to appear, it is slightly different because it uses a different extension:
.wsf (Windows Script File).

This programming language allows mixing JScript and VBScript scripting languages into a single file, or other scripting languages.
These types of scripts can also be used to connect many other external scripts together with a tag system as HTML.
This leaves a good margin of evolution to this infection ..

Like the previous version, the malicious script is encoded multiple times :

Microsoft Excel.WsF

UsbFix detect and remove this variant, for now only the one below is known but UsbFix is set to detect this variant in all form as possible.
