The RTF document contains OLE object data and an \objupdate directive, indicating it is designed to activate embedded objects. The presence of a 'SE_ENABLE_LURE' heuristic firing and the document body's instruction to 'click Enable editing' strongly suggest a social engineering tactic to bypass security measures and execute embedded malicious content, likely a downloader.

Heuristics 4

  • \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
  • Embedded OLE object medium RTF_OBJEMB
    RTF contains \objemb — embedded OLE object
  • 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
