T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The RTF file contains embedded OLE objects that are automatically linked and updated, indicating an attempt to execute external code. ClamAV identifies this as Rtf.Dropper.Agent-6831651-0, a known dropper. The presence of URL monikers within the OLE object data strongly suggests the file's purpose is to download and execute a secondary payload.
