The PDF contains a large number of embedded links, many pointing to Shopify domains, but one critical link directs to a known malicious redirector at `ttraff.ru`. The document body, though heavily obfuscated, contains text related to 'Destiny 2 black armory power level guide' and the malicious URL, suggesting a lure to trick users into clicking the malicious link. The presence of a malicious redirector indicates an attempt to lead the user to a compromised site or a phishing page.

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.
