T1566.001 Spearphishing Attachment
The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various domains, each hosting a PDF file with a numeric or slug-based filename. This pattern suggests the document is part of a link farm or SEO manipulation scheme, potentially to distribute malicious content or improve search rankings for malicious sites. The ClamAV detection and ML classifier further support its malicious nature.
