Patching Software Underclocks (Cheat Engine, Game Speed Changer, etc)

This is the exact method from RapeGuard.

Code:

---

__forceinline void KillGunz()
{
    _asm
    {
        XOR EAX,EAX
        XOR ECX,ECX
        mov dword ptr ds: [esp+4],0
        mov eax, dword ptr ds: [0x6272B0]
        jmp eax
        SHL ECX,9
        SHR EAX,7
        OR EAX,ECX
        NOT ECX
        AND EAX,1
        DIV EAX
        retn
    }
}


bool IsAddressHooked(unsigned long address)
{
    BYTE* offsetValue = (BYTE*)address;
    return (*offsetValue == 0xE8 || *offsetValue == 0xE9 || *offsetValue == 0x7E || *offsetValue == 0x74 || *offsetValue == 0xFF);
}

void UnderclockThread()
{
    SetThreadPriority(GetCurrentThread(), THREAD_PRIORITY_LOWEST);
    SetThreadPriority(GetCurrentThread(), THREAD_MODE_BACKGROUND_BEGIN);
    DWORD getTickCount = (DWORD)GetProcAddress(GetModuleHandleA("kernel32.dll"), "GetTickCount");
    DWORD queryPerformanceCounter = (DWORD)GetProcAddress(GetModuleHandleA("kernel32.dll"), "QueryPerformanceCounter");

    while(true)
    {
        if (IsAddressHooked(getTickCount) || IsAddressHooked(queryPerformanceCounter) || GetModuleHandleA ("SpeedHack.dll") != NULL || GetModuleHandleA ("MyHookDll.dll") != NULL)
        {
            HackDetected(Underclocking);
            Sleep(5000);
            KillGunz();
        }
        Sleep (5000);
    }
}

Thread Wrapper Class:

Code:

---

#pragma once
#ifndef _THREAD_H_
#define _THREAD_H_

#include <Windows.h>

typedef void ThreadFunction();

class Thread
{
public:
    enum ThreadState
    {
        TS_NONE,
        TS_RUNNING,
        TS_SUSPENDED
    };

public:

    Thread(ThreadFunction _thread)
    {
        threadHandle = CreateThread (NULL, NULL, (LPTHREAD_START_ROUTINE)_thread, NULL, NULL, &threadId);
    }

    DWORD GetThreadId() { return threadId; }
    HANDLE GetHandle() { return threadHandle; }
   
    int GetState()
    {
        DWORD status = 0;
        BOOL exitCode = GetExitCodeThread (threadHandle, &status);

        if (!exitCode)
            return TS_NONE;

        if (status != STILL_ACTIVE)
            return TS_SUSPENDED;

        return TS_RUNNING;
    }
private:
    DWORD threadId;
    HANDLE threadHandle;
};
#endif

---

Usage:

Global Vars:

Code:

---

Thread* underclockThread = NULL;

---

OnAttach / DllMain:

Code:

---

underclockThread = new Thread(UnderclockThread);

Wait, since when was Game Booster a "Underclocking" programm ...?
Its just closing not essential windows services and defrags the memory ó.O

Whoops, I meant Game Speed Changer, lol.

Hmm thank you jacob this is usefull

oh dam, thats good. really usefull, VB right?

Google

wtf...??? what you mean with that im just asking if he made it in VB = Visual Basic, so i know i can compile it in VB, some people use Netbean or something else.,

jj,

Thajj you call your self a developer? even a idiot sees this isn't VB

Thanks for the thread wrapper.

Watch the structure. VB doesn't use brackets.(I'm not sure about this, but according to some scripts I've seen it doesn't use brackets.).

Thanks, but how do I compile it?

Sorry about my "noob" question.
Someone tell me please how to do and how to use it.

and Please don't dispraise me

you need to know with what he created it, so you know yu can compile it with that programm, wtf i was asking i never saied i was sure... and i am into item/map/xml/html/php developing not into asm/vb/c++ and all the others... dam dont get so mad if you dont even know what i do..

relax touch..

Thanks but
I don't know what's he used.

and

I don't have knowledge about C++ ASM or etc. anymore.

So i can't compile it.
