MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains numerous URLs advertising free game hacks and in-game currency, with a primary URL pointing to 'netcdn.tw'. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs suggests an attempt to direct the user to download or interact with malicious content. The document body's content reinforces this lure, aiming to trick users into downloading potentially unwanted or harmful software.
