T1566.001 Spearphishing Attachment
The PDF contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, which is indicative of a link farm or SEO spamming technique. While the URLs themselves are marked as benign, the sheer volume and the heuristic firing suggest an attempt to direct users to external content, potentially as a precursor to a more malicious activity or to manipulate search engine rankings. The ML classifier also flagged this PDF as malicious.
