Heuristics 4

  • Image-heavy PDF hides clickable URL with PDF string escapes high PDF_ESCAPED_URI_IMAGE_LURE
    PDF is image-heavy with little real text and its clickable HTTP(S) URI is encoded with PDF octal escapes. This combination is common in credential-phishing PDFs that render a screenshot-like prompt and obscure the destination from simple URL extractors.
  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 2 image(s), only 0 text block(s), carries a click-outward action, and is only 43 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • Fake invoice / payment lure low SE_INVOICE_LURE
    Document contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
  • 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.
