The file was detected by ClamAV as Doc.Downloader.Sload-6794696-0, indicating it functions as a downloader. Although VBA macros could not be extracted due to an unsupported format, the presence of an embedded URL and the ClamAV signature strongly suggest the document's purpose is to download and execute a secondary payload. This aligns with the typical behavior of the Sload family.
