MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF contains a large number of external links, many of which point to other PDF files, suggesting a link farm designed to host malicious content or redirect users to malicious sites. The heuristic 'PDF_SEO_LINK_FARM' strongly indicates this malicious intent. The primary IOC is the first external URI found, which appears to be a download link.
