MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic, which is a common tactic for distributing malware or phishing content. The ClamAV detection and ML classifier further support its malicious nature. The document body, though partially obfuscated, contains references to URLs that likely serve as download locations for further malicious payloads.
