MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document body contains a URL pointing to a game hack. The presence of multiple embedded URLs, including one at offset 0x230, suggests the document is designed to redirect users to download potentially malicious content. The document's content and embedded URLs indicate a phishing or scam attempt, likely related to game cheats or in-game currency.
