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. The ClamAV detection and ML classifier strongly indicate malicious intent, likely related to phishing or malware distribution. While no scripts were explicitly extracted, the embedded URLs are the primary indicators of the attack pattern.
