The PDF document contains multiple embedded URLs, with the primary one being http://fluffyagain.com/uploads/1/3/0/4/130436020/130436020.html#panasonic+kx-t7730+telephone+black, which is presented as a product listing for a Panasonic phone. The ML classifier strongly flagged this PDF as malicious. The presence of numerous similarly structured, unknown-reputation URLs suggests a coordinated phishing or malware distribution effort.

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.
