The PDF file contains a large number of embedded links to external PDF documents, a technique often used for SEO manipulation or to distribute malicious content. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a malicious classification. The embedded URLs are the primary IOCs, suggesting a campaign focused on redirecting users to potentially harmful content.
