The PDF contains a large number of embedded URLs pointing to other PDF files, a technique often used for SEO manipulation or to distribute further malicious content. ClamAV detected this as Pdf.Phishing.TtraffRobotInstall, and ML classifiers also flagged it as malicious. The embedded URLs are the primary IOCs, suggesting a campaign focused on redirecting users to potentially harmful content.
