MITRE ATT&CK

T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The RTF file contains multiple OLE object data sections, with high confidence heuristics indicating the presence of embedded OLE objects and excessive hex data. Specifically, the CVE-2012-0158 heuristic firing strongly suggests exploitation of a vulnerability related to MSCOMCTL.ListView, which allows for arbitrary code execution. The embedded artifacts are likely payloads or exploit components.

Heuristics 6

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.
Large hex data blocks in OLE object high RTF_EXCESSIVE_HEX

RTF contains ~1007KB of hex-encoded data inside \objdata sections — may hide a payload
OLE object data medium RTF_OBJDATA

RTF contains 3 \objdata section(s) — embedded OLE objects
Embedded OLE object medium RTF_OBJEMB

RTF contains \objemb — embedded OLE object
OlePres presentation stream in RTF OLE object medium RTF_OLEPRES_STREAM

RTF contains an embedded OLE object with an OlePres presentation stream. OlePres is an OLE presentation marker and is not enough on its own to identify CVE-2025-21298.
