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

The PDF file contains a large number of embedded links to external PDF files hosted on various domains. This technique is often used to create link farms for SEO manipulation or to distribute malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or traffic redirection intent. No scripts were extracted from this sample.
