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

The PDF contains a large number of embedded links to external PDF files hosted on various domains, indicating a link farm or SEO manipulation tactic. The ClamAV detection and ML classifier strongly suggest malicious intent, consistent with phishing or malware distribution. No scripts were extracted, so the primary attack vector appears to be the embedded URLs.
