The PDF file contains a heuristic match for PDF_MALICIOUS_REDIRECTOR_LINK, indicating it directs users to known malicious infrastructure. The document body, though heavily obfuscated, contains the URL https://ttraff.ru/pify?keyword=blood+sugar+test+report+pdf, which is likely intended to trick the user into believing it is a legitimate report. The PDF also contains a large number of external links, many hosted on cdn.shopify.com, which is flagged as a PDF_SEO_LINK_FARM. The primary malicious IOC is the redirector URL.

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.
