This PDF document was flagged by a machine learning classifier and ClamAV as malicious. It contains an embedded URI pointing to 'https://leonvi.ru/strik?utm_term=marlin+glenfield+model+60+recoil+buffer', which is likely a phishing or malware distribution site. The document's structure and embedded URLs suggest it is designed to trick users into visiting a compromised site, potentially for credential harvesting or further malware delivery.

  • 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.
