MITRE ATT&CK

The PDF file contains a large number of embedded URLs, forming a link farm, and includes a visual call-to-action button. ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly suggests a phishing or traffic redirection campaign. The primary attack pattern involves luring users to download further malicious content via the numerous linked PDFs.
