The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://ttraff.com/wix?keyword=physics+constants+pdf'. While the document body is heavily obfuscated, the presence of this malicious URL strongly suggests an attempt to lure the user to a harmful site. No scripts were extracted from this sample.

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.
