Heuristics 4

  • Image-only PDF lure links to a brand-impersonating host high PDF_IMAGE_LURE_BRAND_HOST_LINK
    PDF is image-heavy with little real text and its clickable action targets a host carrying the brand name 'walmart' as a domain label / subdomain segment on a registered domain that is not that brand's own and is not known-good (e.g. 'udai.walmartnewjersey.com', 'paypal-secure.net'). Unlike the homoglyph-typosquat rule, the brand here is spelled correctly but glued onto an unrelated domain — the canonical brand-impersonation phishing / scam carrier shape behind a screenshot-like lure page.
  • 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 74 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • External URI info 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.
