The RTF file contains OLE object data and uses an \objupdate directive, indicating it's designed to activate embedded objects. The SE_ENABLE_LURE heuristic confirms the document instructs the user to enable editing, a typical social engineering tactic to bypass security measures and execute malicious content.

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
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
