The PDF document contains a large number of external links, a technique often used for SEO spam or to redirect users to malicious sites. The ML classifier strongly indicated maliciousness. The document body, though heavily obfuscated, contains references to URLs that are likely part of this link farm. The primary intent appears to be driving traffic to these external sites.
