The PDF contains a critical heuristic firing for a malicious redirector link, pointing to traff.ru. The document body, though heavily obfuscated, contains the same URL and text suggesting a lure for a free agenda. The PDF also contains a large number of embedded links, many of which point to Shopify domains, but one critical heuristic indicates these are part of a link farm. The primary malicious URL is https://ttraff.ru/pify?keyword=agenda+2020+pdf+gratis+para+imprimir, which likely serves as a gateway to further malicious content.

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.
