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

The file is identified as malicious by ClamAV with the signature 'Doc.Malware.Emotet-9762310-0', and contains VBA macros. The 'Document_Open' macro is present and uses 'CreateObject', indicating an attempt to execute code. The VBA script is heavily obfuscated, but the presence of these indicators strongly suggests Emotet malware, which commonly uses this infection vector to download further stages.
