MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files, a technique often used for SEO poisoning or to distribute malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent. The document body, though heavily corrupted, contains text related to travel, suggesting a lure to trick users into clicking the malicious links.
