The PDF contains a large number of embedded links to external PDF files, a technique often used for SEO manipulation or to distribute malicious content. The ML classifier also flagged this PDF as malicious with high confidence. While no scripts were explicitly extracted, the PDF structure and embedded links suggest a potential for malicious redirection or content delivery, possibly initiated by user interaction with the links.
