T1566.001 Spearphishing Attachment
The PDF document contains a large number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic. These URLs point to various book titles, but the sheer volume and the nature of the heuristic suggest a link farm or SEO manipulation tactic. The ML classifier also flagged the document as malicious with high confidence. No scripts were extracted from this sample.
