monohook's Introduction

MonoHook

本代码的功能是运行时修改C#函数

特性：

运行时直接修改内存中的 jit / aot 代码，不会修改真实文件。
不影响调试及堆栈回溯。
同时支持 .net 2.x 与 .net 4.x。
支持 unity4.7.2, unity5.x, unity 2017 ~ 2021 (只要Unity不更换 runtime 就可以自动支持以后的版本)。
使用方便，在C#内定义签名与原始方法相同的两个方法注册后即可生效。

支持平台

Editor (Windows, Mac Intel/Silicon)
Android mono/il2cpp(armv7a, armv8a)
Windows mono/il2cpp(x86, x64)

预览

原理

MethodInfo.MethodHandle.GetFunctionPointer().ToPointer() 指向了 jit 后的 native 代码，因此修改此地址的代码即可以修改功能。
通过一系列跳转就可以巧妙的替换原函数实现，同时也保留调用原函数的功能。
本代码的实现与下面 reference 的实现略有不同，比其使用更少的字节，Hook 成功率更高，具体实现可以看代码。

使用方法

   [InitializeOnLoad] // 最好Editor启动及重新编译完毕就执行
   public static class HookTest
   {
        static HookTest()
        {
            if(_hook == null)
            {
                Type type = Type.GetType("UnityEditor.LogEntries,UnityEditor.dll");
                // 找到需要 Hook 的方法
                MethodInfo miTarget = type.GetMethod("Clear", BindingFlags.Static | BindingFlags.Public);

                type = typeof(PinnedLog);

                // 找到被替换成的新方法
                MethodInfo miReplacement = type.GetMethod("NewClearLog", BindingFlags.Static | BindingFlags.NonPublic);

                // 这个方法是用来调用原始方法的, 要求必须添加 [MethodImpl(MethodImplOptions.NoOptimization)]，否则在 arm il2cpp 下会随机 crash
                MethodInfo miProxy = type.GetMethod("ProxyClearLog", BindingFlags.Static | BindingFlags.NonPublic);

                // 创建一个 Hook 并 Install 就OK啦, 之后无论哪个代码再调用原始方法都会重定向到
                //  我们写的方法ヾ(ﾟ∀ﾟゞ)
                _hook = new MethodHook(miTarget, miReplacement, miProxy);
                _hook.Install();
            }
        }
   }

monohook's Issues

Hook doesn't work On GenericMethod

for example : UnityEngine.Object Api: public static T Instantiate(T original) where T : Object;
when i Get the this GenericMethod, and then us
"MethodInfo miTarget = genericMethod.MakeGenericMethod(typeof(UnityEngine.Object)",

and then Code:

[MethodImpl(MethodImplOptions.NoOptimization)]
private static UnityEngine.Object GameInstanceNew(UnityEngine.Object go)
{
    Debug.LogFormat("【自定义实现】Object.Instantiate(Object original), Prefab名称：{0}", go.name);
    UnityEngine.Object  obj= GameInstanceProxy(go);
    return obj;
}
[MethodImpl(MethodImplOptions.NoOptimization)]
private static UnityEngine.Object GameInstanceProxy(UnityEngine.Object go)
{
    // 此处的函数实现永远不会起作用，随便写
    Debug.Log("something" + go.ToString());
    return null;
}
MethodInfo miReplacement = new Func<UnityEngine.Object, UnityEngine.Object>(GameInstanceNew).Method;
MethodInfo miProxy = new Func<UnityEngine.Object, UnityEngine.Object>(GameInstanceProxy).Method;
_hook_Instance = new MethodHook(miTarget, miReplacement, miProxy);
_hook_Instance.Install();

And when Call UnityEngine.Object:Instance() Again , then Unity crash~!

Code no Error in Runtime, but hook doesn.t work, who know reason

android mono (unity2019/2020崩溃)

跑test会在2019/2020崩溃，2021正常

建议改名为MonoHook

hook已经有名次和动词此意，hooker跟钩子没有关系，反而有prostitute之意

2019.4.40编辑器下gameobject.setactive不好用

调用MonoHook.Test.GameObject_SetActive_HookTest.Test(gameObject)好用
调用gameObject.SetActive(false)不好用
GameObject_SetActive_HookTest已经使用了InitializeOnLoad

是我工程设置或者脚本写错了吗

android unity not work

How to hook the property of an interface?

Here for example has a interface called A

public interface A{
    int p1{get;set;}
}

and I what to hook it, but it throw an error:

Missing or incorrect header for method set_MuzzleEular
[17:26:35.726] [BobH_ATRI2] [ERROR]   at (wrapper managed-to-native) System.RuntimeMethodHandle:GetFunctionPointer (intptr)

  at MethodHook..ctor (System.Reflection.MethodBase targetMethod, System.Reflection.MethodBase replacementMethod, System.Reflection.MethodBase proxyMethod) [0x00000] in <filename unknown>:0

只能Hook静态方法吗，请问一下普通Method如何Hook

请问一下普通Method如何Hook

能否支持对运行时动态创建的函数

需求场景：
有一个函数A：输出A
需要在程序运行时：替换函数A的输出内容输出B 然后在执行函数A 再输出B
目前实现方式：遍历函数A的参数属性返回值等写入cs代码文件中重新编译然后进行HOOK
理想实现方式：遍历函数A的参数属性返回值等创建一个动态函数作为绑定代理然后进行HOOK

崩溃

unity 2021.3.x unity2022.3.x启动界面就崩溃 unity2020正常

获取属性时不能正确Hook

参考DotNetDetour 中解释的，关于属性其实是 get_XXX的格式，在MonoHook中确实能够正确找到这个函数，Install也没什么问题，但是测试发现并不能正确Hook到，想向大佬请教一下。

//这是需要Hook的目标
public class HookTarget : MonoBehaviour
{
// 这是随便挂在场景里的一个MonoBehaviour类，挂了一个Text用来输出
    public Text Log;

    public static string TestStaticString
    {
        get
        {
            return "This is original,not hook.";
        }
    }

//场景中挂了一个按钮来触发这个函数
    public void CheckTestString()
    {
        Console.WriteLine("CheckTestString Start");
        Log.text = TestStaticString;
        Console.WriteLine("CheckTestString Over");
    }

}

然后随便用了个注入器，应该是叫MInjector，注入之后可以运行一个入口函数，入口函数中进行Install的逻辑大体如下：

    public class HookClass
    {
      /// <summary>
        /// Hook类型的属性
        /// </summary>
        public static void HookPropertyMethod()
        {
            Console.WriteLine("HookPropertyMethod Start.");
            //获取需要Hook的类型
            Type type = Type.GetType("HookTarget,Assembly-CSharp.dll");

            //获取类型上的目标方法，这里打印过日志，确认是找到了对应方法的
            MethodInfo miTarget = type.GetMethod("get_TestStaticString", BindingFlags.Static | BindingFlags.Public);

            //Hook后重新定向的新方法，这里直接指向本类
            type = typeof(HookClass);

            // 找到本类上 名为 NewMethod 的方法，准备替换目标方法
            MethodInfo miReplacement = type.GetMethod("NewStaticString", BindingFlags.Static | BindingFlags.Public);

            // 创建一个 Hook 并 Install ，这样就能把方法都重定向到新方法来
            MethodHook _hook = new MethodHook(miTarget, miReplacement, null);

            _hook.Install();
            Console.WriteLine("HookPropertyMethod Over.");
        }

        public static string NewStaticString()
        {
            return "Hello,Hook!";
        }

//这里也试过添加参数（觉得可能和实例化的类一样会把自身作为第一个参数），但是还是不行
        public static string NewStaticString_2(object target)
        {
            return "Hello,Hook!";
        }
}

大体的方法和流程如上，对于类普通方法和静态方法的Hook试过可行，但是不知道属性是否也可以Hook?

先谢过！

使用注入Hook的方式运行时，无法正确运行原函数

我fork了一份进行了修改，配合注入工具能够成功注入到运行时的 Unity 程序中，大部分功能也都正常，但是有几个问题，不知道大佬能不能给点思路（对汇编不是很熟悉）：

能够Hook到指定的函数，也确实能够跳转到新函数，但是调用占位原函数时失效，没有效果
Hook带有参数的方法时无效，Hook不到具体的参数

大概的逻辑在这里：https://github.com/pgw00k/MonoHook

关于IL2CPP

你好，看到readme里写的 “il2cpp 需要增加一个 so 来调用 mprotect 方法”
能否请教下大概要怎么做？
我打算给一个游戏做MOD支持（它是IL2CPP编译的）

Arm64下为什么不使用更短的绝对跳转？

LDR x17, #0x8
BR x17
addr

这里使用x16 x17 x18都可，前2个状态寄存器，后1个平台寄存器。在标准的情况下，arm64下几乎不会使用它们。它们完全可以随意使用，仅手写asm的情况下才会被占用

il2cpp android support

Hi great project, are you planning add android il2cpp support?

There is android native hook library witch is using mprotect https://github.com/iqiyi/xhook maybe it could help

报错信息是：error: 'pthread_jit_write_protect_np' is unavailable: not available on iOS

void Test<T>()

你好，我这边遇到一个问题，使用void Test()方法时，如果T是结构体，正常运行，如果T是类（Class）,则会直接崩溃，有什么好的解决方案么？测试代码如下工程

MonoHook makes Unity2021.3.6 crash

Upgraded my project from Unity2019 to 2021.3.6 recently, and MonoHook started making Unity crash when it calls the Monohook funcs(start unity; press Play Button in editor; modified script). It's not 100% crash, but once my computer randomly met this crash, i can repeat the crash by pressing Play Button until i removed the "new MethodHook()" invoking functions. And this type of crash can be repeated on other computers.
自从最近升级到2021.3.6后，开始遇到MonoHook的crash问题。只要是调用到了绑定hook的代码，无论是在启动unity、点击编辑器的play，修改了script，都会随机的遇到unity native crash。已经定位确实是monohook的绑定代码造成的（只要不调用，就必然不会crash）。在好几台电脑上都可以重现。保持projectSetting里ReloadDomon默认开启的状态下，通过点击play可以比较快速的，重现率高的，重现这个问题。
麻烦调查一下，否则就不能再用MonoHook了:(

crash info:
Obtained 2 stack frames
RtlLookupFunctionEntry returned NULL function. Aborting stack walk.

test env: scripting backend: mono. ApiCompatibilityLevel: .both .net framework or .net standard

would you please have a look at this issue? thanks a lot!
