The RTF document contains OLE object data and an object update trigger, indicating an attempt to execute embedded content. While the document body is heavily obfuscated and unreadable, the heuristics strongly suggest that the file is designed to exploit OLE object handling to run malicious code. No specific family could be identified, and the primary IOC is the extracted OLE object data.

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 1 \objdata section(s) — embedded OLE objects
