The sample is an RTF document that contains OLE object data and an instruction to enable editing, indicating a lure to bypass security measures. The heuristic 'SE_ENABLE_LURE' strongly suggests the document's content is designed to trick the user into enabling macros or editing. This is a common technique for malware droppers to execute their payload.

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
