T1203 Exploitation for Client Execution

The RTF file contains OLE object data and uses an \objupdate directive, which strongly indicates an attempt to exploit vulnerabilities associated with OLE object activation. This technique is commonly used to execute arbitrary code or download malicious payloads. No specific family could be identified due to the lack of further indicators.
