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

The file is a Microsoft Word document containing a VBA macro, specifically triggered by the Document_Open event. ClamAV identifies this as Doc.Trojan.Walker-9. While no specific malicious URLs or scripts were extracted, the presence of the Document_Open macro and the ClamAV detection strongly indicate that the VBA code is designed to execute malicious actions upon opening the document, likely leading to the download or execution of a secondary payload.
