The PDF was flagged by ML classifiers and ClamAV as malicious, indicating a high likelihood of malicious intent. An external URI pointing to 'traffine.ru' was detected, suggesting the document is designed to redirect users to a potentially harmful website. No scripts were extracted, but the presence of embedded URLs and the overall detection by security tools strongly suggest a phishing or malware distribution attempt.

  • 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.
