MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as malicious by ClamAV with critical heuristics firing for OLE_VBA_MACROS and OLE_VBA_DOCOPEN, indicating the presence of VBA macros and specifically a Document_Open macro. The document body discusses literary analysis, a common lure to trick users into enabling macros. No scripts were extracted, and no specific IOCs were identified beyond the macro presence.
