The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://ttraff.cc/wix?keyword=captain+marvel+putlockers'. Additionally, it exhibits characteristics of a PDF link farm, with numerous embedded links, many of which point to 'static.usrfiles.com'. The document body, though heavily obfuscated, contains the same malicious URL, suggesting an attempt to lure users to a potentially harmful site under the guise of providing movie streaming content.

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.
