MITRE ATT&CK

T1059.005 Visual Basic

The file is a Microsoft Word document containing a malicious VBA macro, as indicated by the OLE_VBA_MACROS and OLE_VBA_DOCOPEN heuristics. ClamAV detections further confirm its malicious nature. The macro is likely designed to execute arbitrary code, serving as a downloader or initial access vector. The document body content appears benign, suggesting the malicious functionality is solely within the macro.
