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

The PDF contains a large number of external links, a technique often used in SEO spam or phishing campaigns to drive traffic to malicious sites. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious traffic generation intent. The embedded URLs are likely part of this link farm, aiming to direct users to download further malicious content.
