The PDF contains a malicious redirector link pointing to 'ttraff.com'. This link is presented to the user under the guise of information about the health effects of lead. The ML classifier strongly indicates maliciousness, and the PDF structure itself is suspicious. No scripts were extracted, but the embedded URL is sufficient to classify the attack.

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.
