The PDF file contains a heuristic match for PDF_MALICIOUS_REDIRECTOR_LINK, indicating it directs users to a known malicious URL. Additionally, PDF_SEO_LINK_FARM suggests the document is part of a larger link farm, likely for SEO manipulation or to distribute malicious content. The embedded URL, https://ttraff.link/wix?keyword=bazaar+movie+trailer++pagalworld, is the primary indicator of malicious intent, aiming to redirect users to potentially harmful sites. The document body, though heavily obfuscated, contains this URL and references to movie trailers, suggesting a lure.

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.link/wix?keyword=bazaar+movie+trailer++pagalworld
