The RTF document contains OLE object data and an \objupdate directive, indicating an attempt to exploit a vulnerability for client execution. While no specific script was extracted, the presence of OLE object data suggests the potential for embedded malicious content that could be activated. The file's SHA256 hash is provided as a primary indicator.

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 2 \objdata section(s) — embedded OLE objects
