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

The PDF file contains a large number of embedded URLs pointing to other PDF files hosted on various domains. This technique is commonly used to distribute malicious content or conduct phishing attacks by overwhelming the user with links. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports the phishing and traffic redirection intent.
