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

The sample is a DOCX file containing VBA macros, specifically a Document_Open macro. This macro is designed to overwrite its own code with a payload and then execute it, likely to download and run a second-stage malicious file. The ClamAV detection name 'Doc.Macro.APMPKILL-6097118-0' further supports this malicious intent.
