The PDF file was flagged as malicious by ML classifiers and ClamAV, indicating a phishing attempt. It contains an embedded URI that likely leads to a malicious site, although the specific content of the PDF body is unreadable due to encoding. No scripts were extracted, but the presence of embedded URIs suggests an attempt to redirect the user to a harmful resource.

  • 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.
