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

The ML classifier strongly indicates maliciousness, and the document body contains numerous URLs promoting free in-game currency and hacks for popular games like Coin Master and Roblox. The presence of an external URI pointing to a suspicious domain further supports the malicious intent, likely to deliver a second-stage payload or lead to a phishing site.
