MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains lures for game hacks and free in-game currency, directing users to external URLs for downloads. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports a malicious intent to trick users into downloading potentially harmful content. No scripts were extracted, but the overall pattern suggests a phishing or malware distribution attempt.
