The attachment itself is an Microsoft Excel XLS document that contains malicious macro script. The document presents itself as a standard macro document but has all of its text hidden until the victim enables macros. Notably, all of the content text is accessible to the victim even before macros are enabled. However, a white font color is applied to the text to make it appear that the victim must enable macros to access the content. Once the macro is enabled, the content is presented via the following code: ActiveSheet.Range("a1:c54").Font.Color = vbBlack The code above changes the font color to black within the specified cell range and presents the content to the user. On initial inspection, the content appears to be the expected legitimate content, however, closer examination of the document shows several abnormal artifacts that would not exist in a legitimate document. Figure 2 below shows how the delivery document initially looks and the transformation the content undergoes as the macro runs
