The RTF document contains embedded OLE objects, indicated by the RTF_OBJDATA heuristic. The RTF_OBJUPDATE heuristic suggests that these objects are configured to activate automatically upon opening, which is a common technique for delivering malicious payloads. No document body text or scripts were extracted, limiting the ability to determine the specific payload or its intent. The confidence is moderate due to the lack of script analysis.
