MITRE ATT&CK
T1203 Exploitation for Client Execution

The RTF document contains OLE object data and an \objupdate directive, indicating an attempt to exploit OLE activation for code execution. The high-severity heuristic firing for RTF_OBJUPDATE strongly suggests this exploit vector. No document body or script content was available for further analysis, limiting the ability to identify a specific family or payload.

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 2 \objdata section(s) — embedded OLE objects
