MITRE ATT&CK
T1566.001 Spearphishing Attachment T1566.002 Spearphishing Link

The PDF file contains a large number of embedded URLs pointing to external PDF documents. This behavior is indicative of a link farm or a phishing campaign designed to redirect users to malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports the malicious classification.
