Heuristics 4

  • URL Moniker in RTF OLE object high CVE related RTF_URL_MONIKER_RELATED
    RTF contains a URL Moniker GUID in OLE object context, but no decoded remote target was confirmed. Treat as related OLE2Link attack-surface evidence rather than proof of CVE-2017-0199 exploitation.
  • Large hex data blocks in OLE object high RTF_EXCESSIVE_HEX
    RTF contains ~1526KB of hex-encoded data inside \objdata sections — may hide a payload
  • OLE object data medium RTF_OBJDATA
    RTF contains 1 \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.
