Heuristics 7

  • ClamAV: Doc.Downloader.Emotet-7577854-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Emotet-7577854-0
  • VBA macros detected medium 4 related findings OLE_VBA_MACROS
    Document contains VBA macro code
  • VBA UserForm hidden-property command stager critical OLE_VBA_USERFORM_HIDDEN_COMMAND_STAGER
    VBA auto-exec macro creates a COM object from a decoded variable and reconstructs command text through Split/Join and hidden UserForm properties such as ControlTipText, Tag, Pages, or HelpContextId. This is a high-confidence macro downloader/loader shape seen in the reviewed OLE set, but it is not an Office CVE exploit primitive.
    Matched line in script
    Pcredycisbbxm = VBA.CVar(Join(Split(Xsnvatpjptax, "}&*$**(){"), NoLineBreakAfter))
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
    Matched line in script
    Set Qylpqzijlaifz = CreateObject(Uxvhkhrlfwq)
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
    Triggers on the COMBINATION of two tokens co-occurring in the same compiled VBA/cache stream: an auto-execution entry point (Auto_Open / AutoOpen / Document_Open / Workbook_Open / Auto_Close / AutoClose) AND a shell/download/object-execution token (Shell, CreateObject, GetObject, PowerShell, cmd.exe, URLDownloadToFile, WinHttp, XMLHTTP, ADODB.Stream, ShellExecute, ExecuteExcel4Macro). Neither token alone fires it — it is the pairing that flags p-code-only or source-extraction-failure macro documents where the visible VBA source is unavailable. The matched tokens are named in the detail line below.
  • Document_Open macro low OLE_VBA_DOCOPEN
    Document_Open macro
    Matched line in script
    Private Sub Document_open()
  • 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.
    URL http://schemas.openxmlformats.org/drawingml/2006/main In document text (OLE body)
