Heuristics 2

  • PDF contains hidden external HTML iframe high PDF_HIDDEN_HTML_IFRAME
    PDF bytes contain a hidden zero-size HTML iframe pointing to an external HTTP(S) URL. This is a strong malicious dropper/redirect indicator and is not expected in ordinary PDF content.
  • 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.
