MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, masquerading as book titles, which is indicative of a link farm designed to attract traffic or potentially host malicious content. The presence of a "download button" heuristic further suggests a deceptive user interaction. While no scripts were extracted, the overall structure and heuristic firings point towards a malicious document likely intended for phishing or traffic redirection.
