The RTF file contains embedded OLE object data and triggers an OLE activation event, indicating it's designed to exploit a vulnerability. The heuristics suggest that the embedded object is intended to be executed, likely leading to the download and execution of a secondary payload. The specific nature of the payload cannot be determined from the provided data, hence the unknown family.

Heuristics 2

  • \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
