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

The ML classifier strongly indicates maliciousness, and the document contains embedded URLs and a visual download lure. The primary URL, https://netcdn.xyz/app/431946152/robux-come-game-hack, is likely the payload or a redirect to it, disguised as game hacks. The presence of numerous other URLs related to game cheats further supports a social engineering attack aimed at tricking users into downloading malware.
