MITRE ATT&CK
T1204 Malicious Link T1566 Phishing

The PDF file contains a large number of embedded links to other PDF files, masquerading as educational content. This 'link farm' technique is commonly used to distribute malware or facilitate phishing attacks. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall' further supports a malicious intent, likely to redirect users to malicious sites or download further payloads.
