MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The ML classifier strongly indicated maliciousness, and the document body contains multiple URLs related to game cheats and hacks, suggesting a lure for potentially unwanted downloads. The presence of a visual download button heuristic further supports this, indicating the document is designed to trick users into clicking links that likely lead to malware or exploit kits.
