Characteristics
This detection covers a malicious Microsoft Word (.doc) document having a filesize of 3,871 bytes that attemps to exploit the CVE-2009-0075 vulnerability patched by Microsoft in the MS09-002 patch release.
The word document uses the xml file format. Upon opening the .doc file, Word may crash. However, it does not always crash--on some occasions nothing directly malicious is visible and Word opens the .doc file fine. A small red cross might be seen temporarily (about a second or two) on the page left above.
There are no macros visible embedded inside the .doc file.
However the file seems to connect to an http address.
A closer examination shows it contains an object classid : "CLSID:AE24FDAE-03C6-11D1-8B76-0080C744F389"
This is a reference to the Microsoft Scriptlet Component, called mshtml.dll.
