The RTF document contains embedded OLE object data and a \objupdate heuristic firing, indicating that the document is designed to automatically activate and execute embedded content when opened. This is a common technique for delivering malicious payloads. No scripts were extracted, and the document body was truncated, limiting further analysis of the specific payload or lure.
