MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and text that lure users with promises of game cheats and free in-game currency. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to redirect users to malicious sites. No scripts were extracted, but the overall pattern indicates a phishing or scam attempt.
