+## Introduction
+
 Microsoft Office is an office suite of applications, servers, and services developed by Microsoft. Microsoft Office contains Microsoft Word, Microsoft Excel, Microsoft PowerPoint and so on. They can support OLE data integration and Virtusl Basic for Application scripting langauage. 
 
 FireEye detected malicious Microsoft Office RTF documents that leverage a previously undisclosed vulnerability. This vulnerability allows a malicious actor to execute a Visual Basic script when the user opens a document containing an embedded exploit. FireEye has observed several Office documents exploiting the vulnerability that download and execute malware payloads from different well-known malware families.
 
 The attack involves a threat actor emailing a Microsoft Word document to a targeted user with an embedded OLE2link object. When the user opens the document, winword.exe issues a HTTP request to a remote server to retrieve a malicious .hta file, which appears as a fake RTF file. The Microsoft HTA application loads and executes the malicious script. In both observed documents the malicious script terminated the winword.exe process, downloaded additional payload(s), and loaded a decoy document for the user to see. The original winword.exe process is terminated in order to hide a user prompt generated by the OLE2link.
