This PDF document is identified as malicious due to its structure and embedded links. It functions as a phishing lure, presenting a screenshot to entice users to click a link. The primary malicious link, https://ggtraff.ru/strik?utm_term=main+nagin+dance+nachna+mp3, redirects to further malicious infrastructure, as indicated by the 'PDF_MALICIOUS_REDIRECTOR_LINK' heuristic. The document also contains a large number of external PDF links, characteristic of a link farm, further supporting its malicious intent.

Machine Learning

  • Nyx PDF Classifier malicious score 0.7261

Heuristics 5

  • 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.
  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.

  • 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 40 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.
