MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document body contains a clear lure for a "Coin Master game hack" generator. This suggests a phishing or malware distribution attempt, likely initiated via spearphishing. The embedded URL points to a suspicious domain, further supporting this assessment.
