The RTF document contains OLE object data and an \objupdate directive, indicating it's designed to embed and activate external content. While no specific payload or script was directly extracted, the presence of these RTF-specific indicators strongly suggests a malicious intent to exploit OLE object activation for delivering a secondary payload. The confidence is moderate due to the lack of directly executable code or network indicators.

Heuristics 2

  • \objupdate forces OLE activation high RTF_OBJUPDATE
    RTF contains \objupdate — forces automatic OLE object instantiation when the document is opened, bypassing user interaction. Almost exclusively seen in Equation Editor exploit documents.
  • OLE object data medium RTF_OBJDATA
    RTF contains 1 \objdata section(s) — embedded OLE objects
