The RTF document contains OLE object data and is configured to automatically update and activate these objects. This suggests an attempt to exploit OLE vulnerabilities to execute embedded code. While no specific script was extracted, the heuristic firings strongly indicate a malicious OLE object is present, likely intended to download and execute a secondary payload.
