MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various domains, suggesting a link farm or SEO manipulation tactic. The document body contains garbled text and a URL that appears to be part of this link farm. No scripts were extracted, and the primary malicious activity appears to be the distribution of these numerous external links.
