T1566.001 Spearphishing Attachment
The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. While many of these links point to benign content, the sheer volume and the nature of the heuristic suggest a potential attempt to manipulate search engine results or to host malicious content disguised as legitimate files. The ML classifier also flagged the document as malicious with high confidence.
