T1566.001 Spearphishing Attachment
The PDF contains a large number of embedded links to external PDFs hosted on the domain 'cefasfese.4pu.com'. This behavior is indicative of a link farm or SEO manipulation tactic, potentially used to distribute malicious content or improve search engine ranking for malicious sites. While no scripts were explicitly extracted, the heuristic 'PDF_SEO_LINK_FARM' and the sheer volume of links suggest a malicious intent to redirect users. The ML classifier also flagged this PDF as malicious.
