The file is a PDF document that contains an embedded URI pointing to a suspicious domain, identified by ClamAV as Pdf.Phishing.Trojan. The ML classifier also flagged this PDF with high confidence. The document body appears to be obfuscated or corrupted, but the presence of the external URI suggests an attempt to redirect the user to a malicious site, likely for phishing or to download further malware.

  • 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.
