MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous embedded URLs that are designed to lure users into clicking them by promising free in-game currency for popular games. 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. No scripts were extracted from this sample, but the overall pattern suggests a phishing or scam attempt.
