The PDF was identified as suspicious due to its structure, which resembles a screenshot lure designed to trick users into clicking an embedded URI. The document body contains numerous URLs, with http://www.diamondcreationslb.com/doc/rdd.htm being the primary one identified by heuristics. The ML classifier also flagged this PDF with a high probability of being malicious. The combination of these factors suggests a phishing or malware delivery attempt.

Heuristics 3

  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 1 image(s), only 1 text block(s), carries a click-outward action, and is only 168 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.
