MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains embedded URLs and a document body that attempts to lure the user into clicking links related to game hacks and free currency. The ML classifier strongly indicates maliciousness, and the presence of external URIs suggests the document is designed to redirect users to potentially harmful sites. No scripts were extracted, but the overall pattern points to a phishing or malware distribution attempt.
