The RTF document contains OLE object data and triggers an object update, indicating an attempt to exploit OLE object handling. This suggests a delivery mechanism for arbitrary code execution. The specific exploit and payload are not detailed in the provided evidence, leading to an 'unknown family' classification.

Heuristics 3

  • \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
