The PDF contains a large number of embedded external links, identified as a PDF_SEO_LINK_FARM heuristic. While the document body is unreadable, the presence of numerous links to external PDF files suggests a scheme to manipulate search engine results or distribute content through a link farm. The ML classifier also flagged the document as malicious. No scripts were extracted, and the primary IOCs are the numerous URLs pointing to external PDF files.
