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, a technique commonly used for SEO poisoning and phishing. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious traffic redirection intent. No scripts were extracted, and the document body was heavily obfuscated, making it difficult to determine the exact payload or further stages.
