MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded URLs pointing to other PDF files, a technique often used for SEO spam or to distribute further malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent, likely related to phishing or malware distribution. No scripts were extracted, but the sheer volume of external links suggests a content-delivery or redirection mechanism.
