MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, identified as a link farm. The ML classifier and ClamAV detection strongly indicate malicious intent, likely for SEO manipulation or to distribute further payloads. No scripts were extracted, but the sheer volume of external links suggests a phishing or content distribution scheme.
