Heuristics 3

  • Clickable URL embeds a recipient email address as a tracking parameter high PDF_URL_RECIPIENT_EMAIL_PARAM
    PDF has a clickable HTTP(S) action whose URL carries a recipient email address as a query parameter (e.g. '?e=victim@example.com') on a host that is not known-good. Phishing kits stamp the target's address into the link so the landing page pre-fills the credential form and tracks the open per recipient; a delivered legitimate link rarely carries the recipient's address in cleartext. Complements PDF_URL_MAILMERGE_PLACEHOLDER, which catches the unrendered token.
  • External URI low PDF_URI
    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.
