MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains lures related to "free spins" for Coin Master and other game-related hacks, directing users to external URLs. The presence of embedded URLs and the ML classifier's high confidence score indicate malicious intent, likely to lead users to phishing sites or download further malware. No scripts were extracted, but the document's content and embedded URLs strongly suggest a social engineering attack.
