The PDF contains an embedded URL that, when clicked, leads to a page discussing 'severe weather alerts app android'. This suggests a social engineering lure to entice users to visit a potentially malicious site. The ML classifier strongly flagged this PDF as malicious. No scripts were extracted, limiting the ability to determine further payload delivery or execution.

Heuristics 3

  • 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.
