The PDF file contains a critical heuristic firing indicating it links to known malicious redirector infrastructure. The document body, though heavily obfuscated, contains a URL that appears to be the target of this redirection. The presence of numerous external PDF links, many hosted on shopify.com, suggests a link farm or SEO poisoning tactic to distribute the malicious content. The primary malicious URL is https://ttraff.cc/pify?keyword=human+chromosome+structure+pdf, which likely leads 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.
    URL https://ttraff.cc/pify?keyword=human+chromosome+structure+pdf
