MITRE ATT&CK

T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The RTF file 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 via spearphishing. No specific family could be identified.

Heuristics 4

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.
Suspicious extracted artifact high 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.
OLE object data medium RTF_OBJDATA

RTF contains 5 \objdata section(s) — embedded OLE objects
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
