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

The sample is identified as malicious by ClamAV with the signature 'Doc.Malware.Emotet-9762408-0'. It contains VBA macros, including a Document_Open macro that uses CreateObject, indicating an attempt to execute code. The presence of VBA macros and the Emotet family attribution strongly suggest this document is a spearphishing attachment designed to download and execute a secondary payload.
