MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded URLs pointing to external PDF files, a technique often used for SEO spam or to redirect users to malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent, specifically identified as phishing. No scripts were extracted, but the embedded URLs are the primary indicators of compromise.
