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

The PDF file contains a large number of external links, indicating a link farm or redirection strategy. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious redirection intent. The embedded URLs are likely used to distribute further malicious content or lead users to phishing pages.
