The RTF document contains embedded OLE object data and an instruction to update the object, indicating an attempt to execute embedded content. The 'SE_ENABLE_LURE' heuristic confirms the document instructs the user to enable editing, a common tactic for macro-based malware delivery. The document body discusses financial auditing to appear legitimate, masking the malicious intent.

Heuristics 4

    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
