MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. While many of these links point to benign-looking book titles, the sheer volume and the nature of the URLs suggest a potential attempt to manipulate search engine results or to host malicious content disguised as legitimate documents. The ML classifier also flagged this PDF as malicious with high confidence.
