MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

This PDF file contains a large number of embedded links to other PDF files, a technique often used for SEO poisoning or to distribute malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly suggests a phishing or traffic redirection purpose. The heuristic 'SE_DOWNLOAD_BUTTON' indicates a lure to encourage user interaction, likely to click on one of the many provided links.
