The RTF document contains embedded OLE objects, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that these objects are designed to be activated automatically, which is a common technique for executing embedded malicious code. The document body is unreadable, and no scripts were extracted, limiting further analysis of the payload's intent.
