MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links and a prominent call-to-action, likely intended to trick the user into downloading a malicious payload disguised as a game hack or cheat. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports a phishing or malware distribution attempt. No scripts were extracted from this sample.
