MITRE ATT&CK
T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The RTF document contains an OLE object that exploits CVE-2017-0199, a known vulnerability for remote code execution. This exploit is designed to download a secondary file from the URL http://95.141.38.110/mo/dnr/tmp/template.doc. The document body contains unrelated Russian text about military tactics, suggesting it is a lure.

Heuristics 5

  • CVE-2017-0199 (OLE2Link / remote URL Moniker) critical CVE likely CVE_2017_0199
    RTF contains a URL Moniker OLE link whose decoded target is remote. Office can fetch and process the response through the CVE-2017-0199 OLE2Link attack path, but the server-side content type is not proven statically.
  • Automatically linked OLE object high RTF_OBJAUTLINK
    RTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
  • OLE object data medium RTF_OBJDATA
    RTF contains 1 \objdata section(s) — embedded OLE objects
  • 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.
  • 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.
