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

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