This PDF file was detected as malicious by ML classifiers and ClamAV, indicating a phishing or trojan payload. It contains an embedded URL that redirects to a suspicious domain, likely intended to host malicious content or phish for credentials. The document body, though heavily obfuscated, suggests a lure related to search queries, further supporting a phishing or social engineering attack vector.

  • 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.
