The sample contains Excel 4.0 macros, specifically an Auto_Open macro that utilizes dangerous functions like RUN and ShellExecute. This indicates the macro is designed to execute arbitrary commands. The embedded URL likely serves as the source for downloading and executing a secondary payload, consistent with downloader malware behavior. The ClamAV detection name 'Doc.Downloader.Docusign0521-9864805-0' further supports this assessment.
