The RTF document contains an OLE object and uses an \objupdate directive, indicating it's designed to activate embedded content. The document body explicitly instructs the user to 'click Enable editing from the yellow bar above,' a common lure to bypass macro security. This suggests the file is a dropper intended to execute malicious code upon user interaction. No scripts were extracted, limiting further analysis of the 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
