MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, a technique often used for SEO poisoning or to redirect users to malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent, likely related to phishing or malware distribution via these links. No scripts were extracted, and the document body's readable text is minimal and corrupted.
