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

The PDF contains a large number of external links, many of which point to PDF files hosted on various domains. This suggests a link farm designed to distribute malicious content or redirect users to phishing sites. The primary URL, http://evacdir.com/..., appears to be a gateway for downloading further payloads.
