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

The PDF contains a large number of embedded links to other PDF files hosted on various domains, a technique often used for SEO manipulation or to distribute further malicious content. ClamAV identified this as Pdf.Phishing.TtraffRobotInstall-7605656-0, and ML classification strongly supports a malicious verdict. No scripts were extracted, but the sheer volume of outbound links suggests a malicious intent to redirect the user.
