The file is an RTF document containing OLE object data, which is often used to embed and execute malicious content. The RTF_OBJUPDATE heuristic indicates that the embedded OLE object is configured to automatically activate, suggesting an attempt to exploit a vulnerability upon opening. No document body or script content was available for further analysis, limiting the ability to determine the specific payload or 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
