T1566.001 Spearphishing Attachment
The PDF document contains numerous embedded links, many of which point to other PDF files hosted on external domains, suggesting a link farm or redirection mechanism. The ML classifier and the PDF_SEO_LINK_FARM heuristic strongly indicate malicious intent, likely to drive traffic to exploit or phishing sites. While no scripts were explicitly extracted, the structure and embedded links are indicative of a malicious PDF designed to trick users into downloading further malicious content.
