T1566.001 Spearphishing Attachment
The PDF contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, which are likely intended to redirect users to malicious content. The ML_NYX_PDF_MALICIOUS heuristic further supports the malicious nature of the document. While no scripts were explicitly extracted, the embedded URLs and the link farm structure suggest an attempt to facilitate a download or redirect, aligning with a spearphishing attachment tactic.
