MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a high-confidence detection for Emotet. The presence of a Document_Open VBA macro, which uses CreateObject, strongly suggests an attempt to execute code. This macro is designed to run automatically when the document is opened, indicating a likely downloader or initial execution stage for a more complex attack.
