MITRE ATT&CK

T1203 Exploitation for Client Execution

The RTF file contains embedded OLE object data and triggers a high-severity heuristic for CVE-2012-0158, indicating exploitation of a known vulnerability in MSCOMCTL.ListView. It also includes a remote URL that is likely used to download and execute a secondary payload, suggesting a downloader or exploit dropper.

Heuristics 7

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.
INCLUDETEXT/INCLUDEPICTURE remote URL high RTF_INCLUDE_REMOTE

RTF document uses INCLUDETEXT or INCLUDEPICTURE with an http:// URL — Word can fetch the remote content on open depending on Office version and external-content settings, enabling remote template injection, NTLM capture via redirects, or payload delivery
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.
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
