MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The ML classifier strongly indicates maliciousness, and the document body contains numerous URLs related to game hacks and free currency. The presence of an external URI pointing to 'netcdn.tw/app' suggests the document is intended to facilitate the download of a secondary payload. The document's content and embedded URLs align with a phishing or scam attempt to trick users into downloading malware.
