The file contains VBA macros, specifically a Document_Open macro that uses CreateObject, indicating an attempt to execute malicious code upon opening. The ClamAV detection explicitly identifies this as Doc.Downloader.Emotet, a known downloader family. The embedded URL, though benign, is part of the document's structure and may have been used in conjunction with other malicious URLs in prior versions or variants.

Heuristics 6

  • ClamAV: Doc.Downloader.Emotet-10024800-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Emotet-10024800-0
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

  • 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.
