Abstract— During several years, the number of the malicious code and the methods for hiding them highly increases. The disseminating the malicious code commonly abuses general files in a way of hiding to avoid its existence from being detected. Among general files, the document files (DOC, PPT, XLS, PDF, etc.) can be easily used for malicious purposes. Therefore, we analyze the PowerPoint 2003 file based on PowerPoint 2003 file format document because it is commonly used by host users. In this paper, we briefly describe the PowerPoint 2003 file format and propose the methods that can be used to store the malicious code. In experiments, we verify whether the proposed methods work well or not.

Index Terms— Malicious code, virus, PowerPoint.
