The PDF contains a link farm and a direct link to a known malicious redirector, disguised as a TV guide listing. The redirector URL is 'https://ttraff.ru/pify?keyword=sky+q+tv+guide+not+showing+listings', which is designed to lure users into clicking on it. The document also contains numerous links to Shopify-hosted PDFs, likely part of an SEO poisoning or link farm strategy to improve search engine ranking for malicious content. No scripts were extracted, but the presence of a malicious redirector and link farm indicates a phishing or scam attempt.

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.
