T1566.001 Spearphishing Attachment
The PDF contains a large number of embedded URLs pointing to external PDF files, as indicated by the 'PDF_SEO_LINK_FARM' heuristic. While the URLs themselves are marked as benign, the sheer volume and the nature of the heuristic suggest a malicious intent, possibly for SEO poisoning or to distribute further content. The ML classifier also flagged the PDF as malicious. No scripts were extracted, but the embedded URLs are the primary IOCs.
