Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
