T1566.001 Spearphishing Attachment
The PDF contains a large number of embedded URLs pointing to external PDF files, a behavior flagged as a link farm. While many of these URLs are marked as benign, the sheer volume and the heuristic firing suggest a malicious intent, possibly for SEO manipulation or to host further malicious content. The ML classifier also strongly indicated maliciousness.
