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

The PDF contains a large number of external links, a technique often used for SEO poisoning or to redirect users to phishing or malware distribution sites. The ClamAV detection and ML classifier strongly indicate malicious intent, consistent with a phishing or redirection campaign. No scripts were extracted, and the document body was heavily obfuscated, limiting further analysis of specific user-facing lures.
