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

The file is a malicious Microsoft Word document containing VBA macros, specifically triggering a Document_Open macro. ClamAV signatures identify it as 'Doc.Trojan.Thus-8'. The document body presents a fake assignment about Women's History Month, likely a social engineering lure to encourage macro execution. The presence of a Document_Open macro strongly suggests an attempt to execute malicious code upon opening the document.
