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

The PDF document contains a significant number of external links, many of which appear to be SEO-farmed, suggesting a tactic to drive traffic to potentially malicious websites. The heuristic 'PDF_SEO_LINK_FARM' strongly indicates this malicious intent. The primary IOC is the first external URI found, which is a complex URL that likely leads to a payload download.
