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 in phishing or malware distribution campaigns. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or traffic redirection intent.

Heuristics 3
