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

The PDF file contains a large number of embedded external links, a technique commonly used for SEO poisoning or to redirect users to malicious content. The ClamAV detection as 'Pdf.Dropper.Agent-9608999-0' strongly suggests malicious intent. The embedded links likely serve as a distribution mechanism for further malware or phishing content.
