MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs, including one pointing to 'netcdn.tw', which is highly suspicious. The document body and extracted URLs suggest a lure for free in-game currency or hacks, likely leading to a download of a second-stage payload. The ML classifier strongly flagged this PDF as malicious.
