MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment T1204.002 Malicious File

The file contains VBA macros, including a Document_Open auto-execution macro, which is a strong indicator of malicious intent. The ClamAV detection explicitly names this as 'Doc.Downloader.Emotet-9784225-0', suggesting it's a downloader for the Emotet family. The VBA script likely executes code to download and run a secondary payload.

Heuristics 6

  • ClamAV: Doc.Downloader.Emotet-9784225-0 critical CLAMAV_DETECTION

    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.
