MITRE ATT&CK
T1566.001 Phishing: Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded links pointing to external PDF documents hosted on various domains. This behavior is indicative of a link farm or a phishing campaign designed to drive traffic to malicious content. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall' further supports this assessment.
