The RTF document contains OLE object data and uses \objupdate, indicating an attempt to exploit OLE activation. The embedded objdata artifact is likely part of the exploit chain. Without a document body or script content, the exact payload and delivery mechanism remain unclear, but the heuristics strongly suggest an exploit targeting RTF parsing to achieve code execution.
