MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The RTF file contains multiple OLE objects and uses the \objupdate directive to trigger their activation, a common technique for executing embedded malware. ClamAV identifies this as Xls.Dropper.Agent-7657208-0, suggesting it's a dropper designed to download and execute a secondary payload. The presence of embedded OLE objects strongly implies an exploitation attempt.
