The PDF file contains a heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK, indicating it directs users to a known malicious URL. Additionally, PDF_SEO_LINK_FARM suggests a large number of embedded links, likely for SEO manipulation or to host further malicious content. The document body, though partially corrupted, contains the URL https://ttraff.ru/pify?keyword=tabela+de+torneio+de+futebol+com+5+times, which is flagged as a malicious redirector. The presence of numerous links, including one pointing to a Shopify domain, suggests a lure to a malicious site.

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.
