MITRE ATT&CK
T1059.001 PowerShell

The PDF contains a large number of embedded URLs, forming a link farm designed to redirect users to malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly indicates a phishing or malicious download attempt. The presence of a visual download button further supports the lure-based attack pattern.
