MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites, many of which are related to game hacks and cheats, suggesting a lure for users seeking unauthorized advantages. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports a malicious intent to redirect users to potentially harmful content. No scripts were extracted, but the overall structure and content point towards a phishing or malware distribution attempt.
