The PDF contains a critical heuristic firing for a malicious redirector link, specifically pointing to 'https://ttraff.me/wix?keyword=fallout+4+mod+load+order+guide+xbox'. This link is presented within the document body, disguised as a 'Fallout 4 mod load order guide', indicating a social engineering lure. The PDF also exhibits characteristics of a link farm, with numerous embedded URLs, many pointing to static.usrfiles.com. The primary malicious intent appears to be redirecting the user to potentially harmful content via the ttraff.me domain.

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.me/wix?keyword=fallout+4+mod+load+order+guide+xbox
