MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded links pointing to external PDF files, a technique commonly used for SEO poisoning and phishing. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious redirection intent. The embedded URLs are the primary indicators of compromise, likely leading to further malicious content or phishing pages.
