The RTF file contains OLE object data and triggers heuristics for CVE-2017-8759, indicating it exploits a SOAP Moniker vulnerability. This vulnerability is known to download and execute arbitrary code, likely a second-stage payload. The presence of ".objdata" and ".objupdate" sections further suggests an attempt to activate embedded OLE objects for malicious purposes.
Heuristics 5
-
SOAP Moniker — CVE-2017-8759 (SOAP WSDL RCE) critical CVE_2017_8759RTF \objdata decodes to OLE data containing the SOAP Moniker — CVE-2017-8759 (SOAP WSDL RCE) CLSID — the vulnerable control/moniker is embedded directly in the document's object stream, the delivery shape of this exploit. RTF objects auto-render when Word opens the file.

-
Automatically linked OLE object high RTF_OBJAUTLINKRTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
-
\objupdate forces OLE activation high RTF_OBJUPDATERTF contains \objupdate — forces automatic OLE object instantiation when the document is opened, bypassing user interaction. Almost exclusively seen in Equation Editor exploit documents.
-
OLE object data medium RTF_OBJDATARTF contains 1 \objdata section(s) — embedded OLE objects
