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

The sample contains VBA macros, including a Document_Open auto-execution macro, and utilizes CreateObject and GetObject calls, indicative of malicious activity. ClamAV detection as 'Doc.Downloader.Emotet-9765530-0' strongly suggests the Emotet family. The VBA script appears to be designed to download and execute a second-stage payload, a common Emotet behavior.

    ClamAV detected this file as malware: Doc.Downloader.Emotet-9765530-0
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • GetObject call high OLE_VBA_GETOBJ
    GetObject 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.
