The RTF document contains OLE object data and uses \objupdate to force activation, indicating an attempt to exploit vulnerabilities or embed malicious content. The presence of objdata suggests the embedding of an executable or script that is likely responsible for downloading and executing a secondary payload. No specific family could be identified, but the technique is common for initial access.
