Heuristics 3

  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 7 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • Image-only PDF lure with a single link to a non-reputable host medium PDF_IMAGE_LURE_NONREPUTABLE_LINK
    PDF is image-heavy with little real text and its only clickable action is a single external link to a host that is not known-good. This is the canonical malspam carrier shape — a screenshot-like 'click to view' page whose sole purpose is to funnel the victim to one redirect/landing URL on a compromised or throwaway domain. Flagged suspicious rather than malicious because the link alone (no shortener / typosquat / brand path) is the only corroborator beyond the image lure.
  • 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.
