MITRE ATT&CK
T1203 Exploitation for Client Execution

The RTF file contains OLE object data and triggers an OLE activation via \objupdate, suggesting it is designed to execute embedded content. The specific nature of the OLE object and its payload could not be determined from the provided heuristics and truncated document body. Therefore, the exact attack pattern and family remain uncertain.

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
  • Embedded OLE object medium RTF_OBJEMB
    RTF contains \objemb — embedded OLE object
