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 distribute further malicious content. The ML classifier and ClamAV detection strongly indicate malicious intent, classifying it as phishing-related. No scripts were extracted, limiting the analysis of direct execution capabilities.
