MITRE ATT&CK

T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The RTF document contains OLE object data and triggers a high-severity heuristic for CVE-2012-0158, indicating exploitation of a vulnerability in MSCOMCTL.ListView. This suggests the file is designed to execute arbitrary code upon opening, likely delivered as a spearphishing attachment. The embedded artifact 'objdata_00_off000013c5.bin' is a shellcode candidate.

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.
