MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a lure for free in-game currency, directing users to download a file from an external URL. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs further supports a malicious intent. No scripts were extracted, but the overall pattern suggests a phishing or malware distribution attempt.
