MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document body contains numerous links to external resources advertising game cheats and free items. The presence of embedded URLs and the document's theme suggest a phishing or malware distribution attempt, likely using a spearphishing attachment as the initial access vector. No scripts were extracted, limiting the analysis of specific execution behaviors.
