MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a large number of embedded URLs disguised as movie download links, which is a common tactic for distributing malicious content. The heuristic 'PDF_SEO_LINK_FARM' and ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly indicate a phishing or malware distribution campaign. No scripts were extracted, but the embedded URLs are the primary indicators of malicious intent.
