The PDF file contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic.

The ML classifier also flagged this PDF as malicious with high confidence. The primary attack pattern appears to be a link farm designed to distribute or obscure malicious payloads.

  • 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.
