T1566.001 Spearphishing Attachment
The PDF contains a large number of embedded URLs pointing to a single domain, identified by the PDF_SEO_LINK_FARM heuristic. While the URLs themselves are classified as benign, the sheer volume and the suspicious domain suggest an attempt to manipulate search engine results or to serve as a distribution point for other malicious content. The ML classifier also flagged this PDF as malicious. No scripts were extracted from this sample.
