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

The PDF file contains a large number of embedded links to external PDF documents hosted on various domains. This behavior is indicative of a link farm, often used for SEO manipulation or to distribute malicious content. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a malicious intent, likely related to phishing or traffic redirection.
