The file is a Microsoft Office document containing VBA macros, specifically a Document_Open macro that executes upon opening. Heuristics indicate the use of CreateObject and p-code execution, consistent with malware downloaders. The ClamAV detection explicitly identifies it as 'Doc.Downloader.Emotet-9783962-0', strongly suggesting the Emotet family and its typical behavior of downloading further malicious payloads.

Heuristics 6

  • ClamAV: Doc.Downloader.Emotet-9783962-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Emotet-9783962-0
  • 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
    Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
  • 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.
