Can server anticheats block Client-Side Ghost Block Spoofer?

Server-side anticheats monitor movement and packet anomalies, while static analysis with Leaf Mod Analyzer identifies hostile and unfair code before mods are loaded.

Client-Side Ghost Block Spoofer

Q: How does Leaf Mod Analyzer detect Ghost_Block_Air_Spoof?

Leaf Mod Analyzer performs static analysis of JVM bytecode and decompiled AST structures matching Matches ClientWorld.setBlockState (method_8652) with Blocks.AIR (field_10124) inside the same method. in an isolated environment without executing untrusted JAR files.

🎮 Minecraft Gameplay Impact

Directly overrides client world blocks with Blocks.AIR without server synchronization, allowing the player to look or phase through solid walls and terrain client-side.

💻 Mod Implementation (Dev Source / Mapped)

// Developer Source (Fabric / Yarn mappings)
public class GhostBlock {
    public static void makeGhost(ClientWorld world, BlockPos pos) {
        world.setBlockState(pos, Blocks.AIR.getDefaultState(), 19);
    }
}

⚙️ Decompiled Representation (Vineflower View)

// Decompiled with Vineflower 1.12 (Intermediary mappings)
public class GhostBlock {
    public static void makeGhost(class_638 world, class_2338 pos) {
        world.method_8652(pos, class_2246.field_10124.method_9564(), 19);
    }
}

🛡️ Bytecode Signature & Static Detection

Matches ClientWorld.setBlockState (method_8652) with Blocks.AIR (field_10124) inside the same method.
