MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and a document body that attempts to lure users into downloading files by promising free in-game currency. The ML classifier also flagged this PDF as malicious. While no scripts were directly extracted, the presence of external URIs and the overall lure suggest a phishing or malware distribution attempt.
