Trojanized Fabric mod impersonating SkyBlockAddons. Repackaged legitimate 'Toggle Sprint Display' mod (author Aeltumn) with a second mixin (ece3700569f8.mixins.json) that hooks Minecraft.run() and reflectively loads a credential stealer (q56p0dnpq.qw1mnsk.dq5m8eecjo.cxo7lzvo). Steals Minecraft username/UUID/accessToken, resolves C2 systemnotifier[.]st via Ethereum eth_call text() on contract 0x9044f5762e43b23ba91d124b51a045f1b51da652 (selector 0x1f1bd692), then downloads and loads a stage-2 JAR fully in memory via DoH. WeedHack/Majanito ecosystem. Static analysis only, sample not executed. IOCs: https://github.com/Kagias/skyblockaddons-trojan-analysis
