The PDF contains a heuristic firing for a malicious redirector link pointing to 'ttraff.com'. This URL is presented within the document body, disguised as an 'African mask craft template'. The PDF also exhibits characteristics of a link farm, with numerous embedded URLs, many of which point to Shopify domains. The primary malicious URL is 'https://ttraff.com/pify?keyword=african+mask+craft+template', which likely serves as 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.
