MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document body contains multiple links to websites promising in-game currency or cheats. The primary external URI, http://netcdn.tw/app/431946152/ways-to-get-robux-game-hack, is likely a lure for a scam or to download further malware. No scripts were extracted from this sample, but the embedded URLs and the nature of the content suggest a phishing or social engineering attack.
