MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs and a prominent call-to-action to download a 'game hack'. The ML classifier strongly flagged this PDF as malicious, and the presence of external links suggests an attempt to redirect the user to a malicious site for payload delivery. No scripts were extracted, but the overall structure and content indicate a phishing or scam attempt.
