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 free in-game currency, suggesting a phishing or scam attempt. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URIs 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 social engineering attack.
