The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://cctraff.ru/aws?utm_term=araba+oyunlar%25C4%25B1+apk+day%25C4%25B1+indir'. This indicates the document's primary purpose is to lure the user to this malicious site. The ML classifier also strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the embedded URL is the primary indicator of malicious intent.

  • 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.
  • Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL
    The same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
  • 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.
