MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as malicious by ClamAV with high confidence. Static analysis detected VBA macros, specifically a Document_Open macro, which is a common technique for executing malicious code upon opening the document. The document body presents as a literary analysis of Edgar Allan Poe's "The Raven", likely a lure to encourage the user to open and interact with the document, thereby triggering the macro execution. No specific IOCs were extracted beyond the presence of the macro itself.
