The PDF document contains a large number of embedded URLs pointing to external PDF files, a technique often used for SEO spam or to distribute malicious content. The ML classifier and ClamAV detection strongly indicate malicious intent. The primary attack pattern involves redirecting users to a network of linked websites, likely to host further malicious payloads or phishing content.
