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

The PDF contains a large number of external links, a technique often used for SEO poisoning or to redirect users to malicious sites. One prominent URL, http://starsearchtool.com/colonist/..., appears to be a download endpoint. The heuristic 'PDF_SEO_LINK_FARM' strongly suggests this is a link farm designed to distribute content or malware.
