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

The PDF file contains a large number of embedded links to external PDF files hosted on various domains. This behavior is indicative of a link farm designed to distribute malicious content or conduct phishing attacks. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports the phishing classification.
