MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document body contains a prominent link to 'netcdn.tw' which is associated with free game hacks. The presence of multiple links to similar scam-like content suggests a phishing or malware distribution attempt. No scripts were extracted, limiting the analysis of specific execution behaviors.
