The PDF contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or SEO poisoning attack. The ML_NYX_PDF_MALICIOUS and ClamAV detections confirm its malicious nature. While no scripts were extracted, the embedded URLs are the primary indicators of malicious activity, likely serving as lures or redirects.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
