The PDF file contains an embedded URL that masquerades as a search result for a specific document. This URL, 'https://mezovuduw.ru/award?keyword=jean+baudrillard+simulacres+et+simulation+pdf', is likely intended to redirect the user to a malicious site. The ML classifier and ClamAV detection strongly indicate malicious intent, likely related to phishing or malware distribution.

  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
