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 items, suggesting a phishing or malware distribution lure. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs indicates an attempt to redirect the user to a potentially harmful site. No scripts were extracted, but the overall structure and embedded URLs point towards a social engineering attack to trick users into downloading malware.
