MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a large number of embedded links to external PDF files hosted on various domains, as indicated by the PDF_SEO_LINK_FARM heuristic. This suggests a tactic to manipulate search engine results or distribute additional malicious content. While no scripts were extracted, the sheer volume of outbound links points to a coordinated effort to redirect users, likely as part of a phishing or SEO spam campaign.
