  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

    PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 57 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.

    PDF contains an external URL action
  • 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.
