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

The ML classifier strongly indicated maliciousness, and the document contains embedded URLs pointing to what appear to be game hack applications. The presence of a visual download button further supports the lure, suggesting the document's primary purpose is to trick users into downloading a secondary payload.
