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 manipulation or to distribute further malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent. Although no scripts were extracted, the sheer volume of external links suggests a coordinated effort to redirect users, potentially to phishing sites or malware downloaders.
