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 automatically activated upon opening, which is a common technique for delivering malicious payloads. The embedded OLE object data itself is the primary IOC, as it represents the malicious component.
