The PDF file contains a link to a known malicious redirector infrastructure, identified by the heuristic PDF_MALICIOUS_REDIRECTOR_LINK. The embedded URL, https://gettraff.ru/123?utm_term=subway+surf+indir+pc, is the primary indicator of malicious intent, likely serving as a lure for phishing or malware distribution. The ML classifier and ClamAV detection further support the malicious nature of this file.

  • 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.
