The PDF contains a link to a known malicious redirector, ttraff.ru, which is flagged by critical heuristics. The ML classifier also strongly indicates maliciousness. While no scripts were explicitly extracted, the PDF structure and embedded links suggest it's designed to lure users to malicious sites, likely for further exploitation or credential harvesting.

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.
