MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded URLs pointing to other PDF files, a technique often used for SEO manipulation or to distribute malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent, consistent with phishing or traffic redirection. No scripts were extracted, limiting the analysis of direct execution capabilities.
