MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a prominent link to 'netcdn.tw' disguised as a download for game hacks, which is a common lure for distributing malware. The ML classifier also flagged this PDF with high confidence. While no scripts were directly extracted, the presence of an external URI and the nature of the lure suggest an attempt to trick the user into downloading a malicious payload.
