T1566.001 Spearphishing Attachment

The PDF contains numerous links to external websites that promise free in-game currency and hacks for popular games. The ML classifier strongly flagged this PDF as malicious, and the presence of these lures indicates a phishing or scam attempt. The embedded links likely lead to sites designed to steal credentials or distribute further malware.
