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 automatically, which is a common technique for exploiting vulnerabilities or delivering malicious payloads. The presence of objdata suggests a complex embedded structure that warrants further investigation for exploit code or secondary payloads.
