MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites advertising game hacks and generators, suggesting a phishing or malware distribution attempt. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports this assessment. The document body, though partially corrupted, contains references to these lures and the wkhtmltopdf authoring application.
