MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.005 Visual Basic

The file is an OLE document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. ClamAV detections indicate it's a known malicious document type. The document body contains text related to local governance and sustainability initiatives, which appears to be a lure to disguise the malicious intent. No scripts were extracted, and the embedded URL is confirmed benign, limiting further analysis of the payload.

Heuristics 5

  • ClamAV: Doc.Trojan.Marker-40 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.Marker-40
  • 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.
