The PDF file contains a link disguised as information about a diet plan. This link, 'https://ttraff.cc/wix?keyword=blood+type+o+positive+diet+food+list+for+weight+loss', is flagged as a malicious redirector. The document's content and the presence of this malicious link suggest a phishing or social engineering attack aimed at redirecting users to harmful websites.

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.
