Heuristics 7

  • ClamAV: Doc.Dropper.Emotet-7546618-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Dropper.Emotet-7546618-0
  • VBA macros detected medium 3 related findings OLE_VBA_MACROS
    Document contains VBA macro code
  • GetObject call high OLE_VBA_GETOBJ
    GetObject call
    Matched line in script
    Set Fptxehhkootud = GetObject(Fceikvua)
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
    Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
  • Document_Open macro low OLE_VBA_DOCOPEN
    Document_Open macro
    Matched line in script
    Private Sub Document_open()
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • 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)

Detection
ClamAV: No threats found
Obfuscation or payload: likely
207 of 304 identifiers look randomly generated (e.g. 'Fqpfpurridzws'); 1 string-concatenation chain(s) — consistent with name-mangling obfuscation.
