Heuristics 4

  • Image-only PDF lure links to a brand-impersonating path on an unrelated host high PDF_IMAGE_LURE_BRAND_PATH_LINK
    PDF is image-heavy with little real text and its clickable action targets a URL carrying a brand name ('dropbox') as a path segment on a host that does not belong to that brand and is not known-good (e.g. 'sodecoperu.com/Docusign/index.php'). This is the credential-phishing carrier shape where a compromised or unrelated host serves a brand-named phishing kit behind a screenshot-like lure page. Distinct from the typosquat-host rule: here the host is honest-looking but the brand lives in the path.
  • 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 54 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.
