MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a mass external link farm, with many links pointing to other PDF files. This is indicative of a phishing or scam attempt, likely to direct users to malicious content or downloads. The presence of a 'download button' heuristic further supports this malicious intent.
