MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains numerous links to external websites advertising game hacks and cheats, with a primary link to 'netcdn.tw'. The ML classifier strongly flagged this PDF as malicious, and the presence of embedded URLs suggests an attempt to redirect users to malicious content. While no scripts were explicitly extracted, the overall structure and embedded URLs point towards a phishing or malware distribution attempt.
