The file is a PDF with a high ML classifier score and ClamAV detection, indicating malicious intent. It contains an embedded URI pointing to 'https://maypoin.ru/award?keyword=abstract+noun+examples+pdf', which is likely a phishing or malware distribution URL. The document body is heavily obfuscated, but the presence of external URIs and the overall detection suggest it's designed to trick users into navigating to a malicious site.

  • 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.
