T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of embedded links to other PDF files, a technique commonly used for SEO poisoning or distributing malware. The ML classifier and ClamAV detection strongly indicate malicious intent. The document body, though heavily obfuscated, appears to be a lure related to books and authors, directing users to external resources.
