The PDF file is identified as malicious due to its structure, which mimics a free manual but contains a critical malicious redirector link. This link, https://cctraff.ru/strik?utm_term=manual+de+carpinteria+pdf+gratis, is designed to lead users to a potentially harmful destination. The heuristic 'PDF_IMAGE_LURE' further suggests a phishing tactic where a visual lure masks a clickable malicious element.

Heuristics 4

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.

  • 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 42 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • 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.
