The PDF contains a large number of embedded links, identified as a 'PDF_SEO_LINK_FARM' heuristic, all pointing to the same domain 'loaminoo.linkpc.net'. While the URLs themselves are currently marked as benign, the sheer volume and structure suggest a malicious intent to redirect users to potentially harmful content. The ML classifier also flagged this PDF with high confidence. No scripts were extracted from this sample.

  • 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.
