MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The ML classifier strongly indicated maliciousness, and the document body contains multiple links to external sites offering game hacks and cheats. The primary URL, http://netcdn.tw/app/431946152/aimbot-exe-roblox-game-hack, suggests the user is being directed to download an executable file. This indicates a likely attempt to trick the user into downloading malware under the guise of game cheats.
