MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs and a document body that advertises free in-game currency and hacks for popular games, aiming to trick users into downloading malicious content. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs further supports a malicious intent to redirect users to potentially harmful sites.
