MITRE ATT&CK

T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The RTF file contains OLE object data and triggers a critical heuristic for CVE-2012-0158, indicating exploitation of the MSCOMCTL.ListView control. A PE header was found within the hex data, and ClamAV identified it as a dropper. This suggests the file is designed to deliver a secondary malicious payload.

Heuristics 5

MSCOMCTL.ListView — CVE-2012-0158 high CVE related CVE_2012_0158

RTF \objdata decodes to OLE data containing the MSCOMCTL.ListView — CVE-2012-0158 CLSID — the vulnerable control/moniker is embedded directly in the document's object stream, the delivery shape of this exploit. RTF objects auto-render when Word opens the file.
ClamAV: Rtf.Dropper.Agent-9965975-1 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Rtf.Dropper.Agent-9965975-1
