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

The file is identified as malicious by ClamAV with a specific Emotet signature. It contains VBA macros, including a Document_Open auto-execution macro, which are designed to run code when the document is opened. The presence of CreateObject and GetObject calls within the VBA code suggests an attempt to interact with the system to download and execute further malicious content.
