MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The RTF document contains OLE object data and a specific \objupdate trigger, indicating an attempt to exploit OLE object activation for malicious purposes. The embedded OLE object, objdata_00_off00001ace.bin, is the primary artifact suggesting the execution of a secondary payload. The lack of readable document body text or scripts prevents further analysis of the specific lure or payload.
