Mittkee dropper kit fake client from donutsmpclients.com: real Fabric-mod wrapper with gibberish Main-Class loader, state-machine + Allatori + invokedynamic/CJK-BSM obfuscation; drops mutyx_client.dll (Mutyx-VM packed native, sha256 3c3547fd…) and executes it via ProcessBuilder. Watermark "Fucked By Mittkee | discord.gg/myserver131". Operator: raiin-mittkee crew (not SilentNet).
