The PDF contains a critical heuristic firing for a malicious redirector link pointing to 'https://cctraff.ru/123?utm_term=fce+ultra+gx+game+genie'. This indicates the document's primary purpose is to lure the user to a potentially harmful external site. The ML classifier also strongly flagged this PDF as malicious. No scripts were extracted, but the embedded URL is sufficient evidence of a phishing or malware distribution attempt.

  • 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.
