The PDF contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic. These URLs point to various book titles hosted on the 'loaminoo.linkpc.net' domain. While the URLs themselves are marked as confirmed benign, the sheer volume and structure suggest a link farm, often used for SEO manipulation or as a distribution vector for malicious content. The ML_NYX_PDF_MALICIOUS classifier also flagged the document with high confidence.

Heuristics 2

  • 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.
