The PDF contains a link farm of external PDF files, a common tactic for phishing or malware distribution. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious intent. The embedded URLs are likely used to redirect users to malicious content or download further stages of an attack.
