Emotet · confidence 95%

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

The file contains VBA macros, including a Document_Open macro, which is a common technique for Emotet. The macro is designed to execute code upon opening the document. The ClamAV detection explicitly names Emotet, increasing confidence in the family attribution. No specific URLs or executable payloads were directly extracted, but the presence of the macro indicates a downloader functionality.

    ClamAV detected this file as malware: Doc.Malware.Emotet-9762373-0
  • 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.
