MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is detected as 'Doc.Trojan.Thus-8' by ClamAV, indicating malicious intent. The presence of a 'Document_Open' VBA macro strongly suggests that the document is designed to execute malicious code upon opening. The document body, appearing to be a social work report, is likely a lure to trick the user into enabling macros. No scripts were extracted, and the VBA macro source was too large to analyze for specific actions.
