The RTF document contains embedded OLE object data, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that this object is designed to be activated, likely leading to the execution of embedded code. The presence of objdata suggests a mechanism for delivering and executing a secondary payload, though no specific script or URL was extracted to detail this further. The confidence is moderate due to the lack of explicit script or URL indicators.
