MITRE ATT&CK
T1203 Exploitation for Client Execution

The RTF document contains an OLE object that exploits CVE-2017-0199, a known vulnerability for remote code execution. This exploit is configured to download a HTA file from the FTP URL ftp://lindrupadmin:abraka555@lindrupmartinsen.no/httpdocs/test/template.hta. The embedded URL http://theoryrelativityquad.info/uag/uag.php is also present, suggesting a potential secondary download or C2 communication channel. The presence of OLE object data and automatic linking further supports the exploitation vector.

Heuristics 5

  • CVE-2017-0199 (OLE2Link / weaponized URL) critical CVE exact CVE_2017_0199_WEAPONIZED_URL
    RTF contains a URL Moniker OLE link to a script/HTA/template-style remote loader, matching the tighter static CVE-2017-0199 shape.
  • 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.
