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

The document presents itself as a download for a Minecraft hack client, which is a common lure for distributing malware. The presence of multiple embedded URLs pointing to game-related hacks and the high ML classifier score strongly indicate malicious intent. The document likely serves as a lure to trick users into downloading and executing a second-stage payload.
