The PDF file contains a heuristic firing indicating a malicious redirector link. The embedded URL, 'https://ttraff.cc/pify?keyword=algorithme+cours+et+exercice+pdf', is the primary indicator of malicious intent. This suggests the document is designed to lure users to a potentially harmful website.

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.
