MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains lures for game cheats and free virtual currency, directing users to external URLs for downloads. The ML classifier strongly flagged this PDF as malicious, and embedded URLs suggest a phishing or malware distribution attempt. No scripts were extracted, but the presence of external links indicates a likely attempt to download a second-stage payload.
