The RTF document contains OLE object data and is configured to automatically update and activate these objects, indicating an attempt to exploit vulnerabilities. The presence of RTF_OBJAUTLINK and RTF_OBJUPDATE heuristics strongly suggests the execution of embedded malicious content. No document body or script content was available for further analysis, limiting the ability to determine the exact payload or family.

Heuristics 3

  • Automatically linked OLE object high RTF_OBJAUTLINK
    RTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
  • \objupdate forces OLE activation high RTF_OBJUPDATE
