A little while back we were investigating the malicious activities of the Freakyshelly targeted attack and came across spear phishing emails that had some interesting documents attached to them. They were in OLE2 format and contained no macros, exploits or any other active content. However, a close inspection revealed that they contained several links to PHP scripts located on third-party web resources. When we attempted to open these files in Microsoft Word, we found that the application addressed one of the links. As a result, the attackers received information about the software installed on the computer.
