MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file contains a VBA macro that is automatically executed via the Document_Open subroutine. This macro appears to copy itself to the NormalTemplate and potentially other documents, suggesting an attempt to establish persistence or spread. The ClamAV detection of 'Doc.Trojan.Thus-8' further indicates malicious intent, likely involving the download and execution of a secondary payload.

Heuristics 5

ClamAV: Doc.Trojan.Thus-8 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Doc.Trojan.Thus-8
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
Document_Open macro high OLE_VBA_DOCOPEN

Document_Open macro
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
