The RTF document contains embedded OLE objects, and a heuristic indicates that \objupdate forces OLE activation. This suggests the document is designed to exploit OLE vulnerabilities or trick the user into activating embedded content, likely to download and execute a secondary payload. No document body or script content was available for further analysis, limiting the confidence in specific attack vectors.

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
