[C# DLL] aHook, use ASM through EndScene hook

[-Ryuk-]

Which issues? I am having exactly zero problems at the moment

The fact that we have to start WoW as admin.

The fact that we have to start WoW as admin.

AFAIK, You only need to start YOUR program as admin?
Turn off UAC (or w/e) and you'll be fine.
I might be wrong, apologizes if so.

No, WoW need to be started as admin too as WoW will call some function which require high privilege.

Hello,


Here is a little dll based on BlackMagic for hooking the EndScene using static address.

It allow to run asm code through the EndScene, have fun with it.

I'll post the source once the last "problem" is fixed, under Win 7 / Vista WoW need to be run as admin, i assume cause of some win API used, i need to do something for grant WoW privilege.

Of course it's easier using injected dll with MS Detours, but anyway i'll post it i'm sure it can be usefull for someone.

Here is sample code to use Lua_DoString :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using aHook;

namespace TestaHook
{
    class Program
    {
        static void Main(string[] args)
        {

            Hook EndScene = new Hook(aProcess.GetProcessIdByName("Wow"));

            UInt32 pDevicePtr = EndScene.BlackMagic.ReadUInt(0x00C76668);
            pDevicePtr = EndScene.BlackMagic.ReadUInt(pDevicePtr + 0x397C);

            UInt32 EndSceneAddr = EndScene.BlackMagic.ReadUInt(pDevicePtr);
            EndSceneAddr = EndScene.BlackMagic.ReadUInt(EndSceneAddr + 0xA8);

            Console.WriteLine(EndScene.Hook_Install(EndSceneAddr).ToString());


                // Command to send using LUA
                String Command = "print(\"EndScene hooked!\");";

                // Allocate memory for command
                uint DoString_space = EndScene.BlackMagic.AllocateMemory(Encoding.UTF8.GetBytes(Command).Length + 1);

                // Write command in the allocated memory
                EndScene.BlackMagic.WriteBytes(DoString_space, Encoding.UTF8.GetBytes(Command));

                // Write the asm stuff for Lua_DoString
                EndScene.Hook_AsmAddLine("mov eax, " + DoString_space);
                EndScene.Hook_AsmAddLine("push 0");
                EndScene.Hook_AsmAddLine("push eax");
                EndScene.Hook_AsmAddLine("push eax");
                EndScene.Hook_AsmAddLine("mov eax, 0x007F1F40"); // Lua_DoString
                EndScene.Hook_AsmAddLine("call eax");
                EndScene.Hook_AsmAddLine("add esp, 0xC");
                EndScene.Hook_AsmAddLine("retn");

                // Inject the shit
                EndScene.Hook_AsmInject();

                // Free memory allocated for command
                EndScene.BlackMagic.FreeMemory(DoString_space);

                // Uninstall the hook
                EndScene.Hook_Remove();

            Console.ReadLine();

        }
    }
}

Could i ask for repost of the dll ?

[rhilor]

please repost the dll, thanks.

Though I doubt aHook still works, here you go.

Yeah, it still works

I am using black rain and I would like to use ahook. This is the line I am having problems with.

Hook EndScene = new Hook(aProcess.GetProcessIdByName("Wow"));

I would like to use something like,

Hook EndScene = new Hook(aProcess.Memory);

or 

Hook EndScene = new Hook(aProcess.Memory.pid);

Any ideas? Thanks for the help.

Random error, could not edit post. Should be,

ObjectManager.Memory

[Danne206]

int PID = aProcess.GetProcessIdByName("Wow"));

Hook EndScene = new Hook(PID);

?

[DarkLinux]

So how does it know what wow I am using? If I am running 4 I will have 4 pids. I have already selected the pid and I use ObjectManager.Memory to call on it. So how would I use ObjectManager.Memory to create a new hook? Thanks!

It doesn't. That's your job.

[DarkLinux]

I have that part working thanks! "READ" My question is, I have the pid in ObjectManager.Memory how can I use that to create a hook. ObjectManager.Memory is from BlackRain.

Make ObjectManager.Memory a wrapper for aHook's memory functions. If you can't figure that out you should go hit the books instead of asking to be spoonfed ridiculously simple code.

Edit:
This is assuming you're using the BlackRain source in your project rather than the compiled DLL.

No one really should have answered my question. It was a really stupid question. +Rep to all for putting up with my stupidity. Thanks! :stick:
