T1566.001 Spearphishing Attachment
The PDF file contains a large number of embedded URLs pointing to external PDF documents, as indicated by the 'PDF_SEO_LINK_FARM' heuristic. While the URLs themselves are labeled as benign, the sheer volume and structure suggest a malicious intent, possibly for SEO manipulation or to host further malicious content. The ML classifier also flagged the document as malicious.
