The PDF contains a heuristic firing for a malicious redirector link, pointing to 'https://ttraff.cc/wix?keyword=darksiders+2+secret+ending'. This URL is presented in the document body, suggesting a lure to trick the user into visiting a malicious site. The PDF also contains a link farm heuristic, indicating it's part of a larger effort to generate traffic or distribute content, with one of the links being 'https://static.usrfiles.com/ugd/40b9e6_fb3baf9f5bd5432c80ccf83f57d7321b.pdf'.

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.
