The RTF document contains OLE object data and an \objupdate directive, indicating it's designed to activate embedded objects. The document body provides a lure related to financial audits, instructing the user to 'enable editing' which is a common tactic to bypass security measures and execute malicious content. The presence of these elements suggests the file is a malicious dropper, though no specific family could be identified.

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
