silentnet-family Minecraft stealer. Sakura-1.20.4.jar - repack of 'sakura' with injected entrypoint com.github.ieZ.
Campaign tag: e00db386-ab62-4dc1-91fd-21ef9ff3e6ef
Steals MC session (username, UUID, accessToken) -> POST /shard/prefireMc, then PNG-stego second stage -> portable Python -> main.py. Uploads latest.log -> /shard/submitMinecraftLog.
C2 via Polygon contract 0x9c0a507300fd902787bb193d80fca5ce6e1bff9a (selector 0xce6d41de).
Stage 2: /cdn/v2/9f4e7a2c1b8d.png
Headers: X-Edge-Cache-Revalidate, X-Runtime-Env
Resolves C2 via DoH (cloudflare-dns.com / 1.1.1.1).
Note: host client (Sakura) references discord.gg/vzXzFpv2gk (its own community server, not C2) - same invite seen in "LuminexBeta" sample. Also references discord.gg/mccheats.
