MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file contains a large number of embedded links to external PDF files, a technique often used for SEO manipulation or to redirect users to 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 campaign to drive traffic to potentially compromised or malicious sites.
