MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an external URI and multiple embedded URLs, suggesting an attempt to redirect the user to a malicious download site. The ML classifier also flagged this PDF as malicious. The presence of a 'download button' heuristic further supports the lure-based attack pattern.
