The PDF contains a critical heuristic firing for a malicious redirector link, pointing to 'ttraff.me'. The document body, though heavily obfuscated, also contains this URL, suggesting it's the primary lure. The presence of numerous other benign-looking Shopify links indicates a potential SEO poisoning or link farm tactic to obscure the malicious destination. No scripts were extracted, and the PDF structure itself does not indicate a specific exploit, leading to an 'unknown family' classification.

Heuristics 3

  • 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.
  • 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.
    URL https://ttraff.me/wix?keyword=%25C3%25A7elik+yumruklar+full+izle+t%25C3%25BCrk%25C3%25A7e+dub
