The file contains VBA macros, including a Document_Open auto-execution macro, which is a common technique for Emotet. The macro uses CreateObject to execute code, indicating it's designed to download and run a secondary payload. The ClamAV detection explicitly identifies it as Emotet, a known downloader family.

    Document_Open macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call

  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Embedded URL info EMBEDDED_URL
