The RTF document contains an embedded OLE object, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that this object is designed to be activated automatically upon opening. The SE_ENABLE_LURE heuristic confirms that the document contains text instructing the user to enable editing, a common tactic to bypass security measures and execute embedded 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
