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

The PDF document contains a large number of external links, indicating a link farm designed to direct users to potentially malicious content. The heuristic 'PDF_SEO_LINK_FARM' strongly suggests this is a malicious tactic. One of the primary external URIs points to 'evacdir.com', which is likely a staging point for further malicious activity.
