The PDF file contains a heuristic firing indicating a malicious redirector link. The embedded URL 'https://ttraff.link/wix?keyword=lonely+island+jack+sparrow' is identified as a known malicious redirector. The document body, though heavily obfuscated, appears to contain this URL, suggesting an attempt to lure the user to a malicious site. No scripts were extracted, limiting further analysis of the payload.

Heuristics 2

  • 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.
  • 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.
