TamperCraft

Introduction

TamperCraft is a Minecraft 1.8.X proxy written in C# that is designed to modify the packets sent to and from the client. Using this proxy, it is possible to circumvent client-sided anti cheat systems because cheats can now be implemented on a separate computer and are therefore undetectable to the anti cheat system.

User interface (coming soon)

TamperCraft offers an easy-to-use UI for use without coding. Built into it are some cheats and their configuration. To use this GUI it is not neccessary to know anything about programming.

API

TamperCraft uses a simple API that makes it possible to easily create code that modifies the packets.

Minecraft auth

To authenticate with the Mojang servers, you can use the CredentialManager that caches tokens, renews them as neccessary and makes dealing with Mojang auth easy. Usage is as follows:

var credentialManager = new CredentialManager();
var loginResult = credentialManager.LogIn(username, password, out SessionToken sessionToken);
if (loginResult != LoginResult.Success)
{
	Console.WriteLine("Error: Could not log in with the specified credentials (" + loginResult + ")");
	return;
}
else
{
	Console.WriteLine("Mojang authentication successful");
}

Creating processors

A simple packet processor that cancels EntityVelocity packets could look like this:

public class AntiVelocityProcessor : IPacketProcessor
{
	public void ProcessClientPacket(PacketEvent packetEvent)
	{
		
	}

	public void ProcessServerPacket(PacketEvent packetEvent)
	{
		if(packetEvent.Id == 0x12)
		{
			packetEvent.Cancelled = true;
		}
	}
}

Registering processors

You have to register the processor like so:

...
var server = new TamperServer(sessionToken, targetServer);
server.PacketProcessors.Add(new AntiVelocityProcessor());
server.Start();
...
