MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document body contains numerous URLs promoting game hacks and free currency. These URLs likely lead to malware downloads or phishing sites. The presence of embedded URLs and the overall theme suggest a social engineering lure to trick users into downloading a malicious payload, likely via a spearphishing attachment.
