MITRE ATT&CK
T1059.005 Visual Basic T1204.002 Malicious File

The file is a Microsoft Word document containing a VBA macro, specifically triggered by the Document_Open event. This macro is likely designed to download and execute a second-stage payload, as indicated by the 'OLE_VBA_DOCOPEN' heuristic and the presence of VBA macros. The ClamAV detection as 'Doc.Trojan.Thus-16' further confirms its malicious nature. No specific family could be identified, but the execution flow points to a downloader.
