MITRE ATT&CK
T1566.001 Spearphishing Attachment

The ML classifier strongly indicated maliciousness, and the document contains embedded URLs and a visual download button. The primary URL, http://netcdn.co/app/431946152/do-things-from-hack-week-ever-make-it-into-roblox-game-hack, likely serves as a lure to download a secondary payload. The document's content and embedded links suggest a phishing attempt related to game currency or cheats.
