The sample contains VBA macros, including a Document_Open auto-execution macro, which is a common technique for Emotet. The macro likely attempts to download and execute a second-stage payload. The ClamAV detection name 'Doc.Downloader.EmotetRed02224-9938637-0' further supports the Emotet family attribution.

    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.
