C++ 读取进程内存多级指针（DLL注入）

我已成功地将.dll注入.exe，需要通过多级指针访问值

这是一个获得正确值的工作示例：

#include <Windows.h>
#include <iostream>
#include <vector>
#include <TlHelp32.h>
#include <tchar.h>
using namespace std;

DWORD dwGetModuleBaseAddress(TCHAR *lpszModuleName, DWORD pID)
{
    DWORD dwBaseAddress = 0;
    HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, pID);
    MODULEENTRY32 moduleEntry32 = { 0 };
    moduleEntry32.dwSize = sizeof(MODULEENTRY32);
    if (Module32First(hSnapshot, &moduleEntry32))
    {
        do {
            if (_tcscmp(moduleEntry32.szModule, lpszModuleName) == 0)
            {
                dwBaseAddress = (DWORD)moduleEntry32.modBaseAddr;
                break;
            }
        } while (Module32Next(hSnapshot, &moduleEntry32));
    }
    CloseHandle(hSnapshot);
    return dwBaseAddress;
}

int main()
{
    DWORD pID;
    DWORD off1, off2, off3, off4, off5;
    DWORD baseAddress;
    DWORD xAddress;
    int newX;
    int currentX;
    char moduleName[] = "TibiaInjected2.exe";
    HWND hGameWindow;
    HANDLE pHandle;

    // Getting handles
    hGameWindow = FindWindowA(NULL, "Tibia - 127.0.0.1:7171");
    GetWindowThreadProcessId(hGameWindow, &pID);
    pHandle = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pID);

    // Getting base address
    DWORD clientBase = dwGetModuleBaseAddress(_T(moduleName), pID);

    ReadProcessMemory(pHandle, (LPCVOID)(clientBase + 0x0031D0CC), &baseAddress, sizeof(baseAddress), NULL);
    cout << "Base address: " << hex << baseAddress << endl;

    ReadProcessMemory(pHandle, (LPCVOID)(baseAddress + 0x4), &off1, sizeof(off1), NULL);
    cout << "Offset 1: " << hex << off1 << endl;

    ReadProcessMemory(pHandle, (LPCVOID)(off1 + 0x4), &off2, sizeof(off2), NULL);
    cout << "Offset 2: " << hex << off2 << endl;

    ReadProcessMemory(pHandle, (LPCVOID)(off2 + 0xA0), &off3, sizeof(off3), NULL);
    cout << "Offset 3: " << hex << off3 << endl;

    ReadProcessMemory(pHandle, (LPCVOID)(off3 + 0x100), &off4, sizeof(off4), NULL);
    cout << "Offset 4: " << hex << off4 << endl;

    ReadProcessMemory(pHandle, (LPCVOID)(off4 + 0x14), &off5, sizeof(off5), NULL);
    cout << "Offset 5: " << hex << off5 << endl;

    cin.get();
}

我通过以下操作直接从静态地址访问值：

int* exampleValue = *(int*)0x12345678;

但是，我们不知道如何对指针和偏移量执行相同的操作。

是的，您可以使用GetModuleHandleNULL；获取main.exe模块的句柄或用与DLL名称匹配的字符串替换NULL

您可以使用此函数循环偏移、取消引用和添加每个级别的偏移：

uintpttr_t FindDMAAddyuintptr_t ptr，标准：：矢量偏移 { uintpttr_t addr=ptr； 对于无符号整数i=0；i int*ammo=int**uintpttr\u t**uintpttr\u t*dynamicPtrBaseAddr+0x374+0x14；

---

但这比它的价值更让人困惑和恼火。

这对我有用，可以像另一个答案一样循环：

DWORD base = *(DWORD*)(clientBase + 0x0031D0CC);
DWORD offsets[] = { 0x4, 0x4, 0xA0, 0x100, 0x14 };

DWORD off1 = *(DWORD*)(base + offsets[0]);
DWORD off2 = *(DWORD*)(off1 + offsets[1]);
DWORD off3 = *(DWORD*)(off2 + offsets[2]);
DWORD off4 = *(DWORD*)(off3 + offsets[3]);
DWORD off5 = *(DWORD*)(off4 + offsets[4]);
cout << "Value: " << off5 << endl;

---

这对我不起作用，但我找到了答案。无论如何，谢谢。@snzm在我的代码dynamicPtrBaseAddr中是指向对象的指针，而不是对象的地址。在代码中，您可以：*DWORD*clientBase+0x0031D0CC，它首先反引用指针。如果在我的代码中使用对象的地址代替dynamicPtrBaseAddr，它将无法工作，因为它不是正确的参数。如果改用指针clientBase+0x0031D0CC，它应该可以正常工作。这就是你有问题的原因吗？让我知道，这样我可以更新我的答案，使之更好。最好使用uintptr\t或类似工具，这样就不必更新x64的代码，只需更改构建即可

DWORD base = *(DWORD*)(clientBase + 0x0031D0CC);
DWORD offsets[] = { 0x4, 0x4, 0xA0, 0x100, 0x14 };

DWORD off1 = *(DWORD*)(base + offsets[0]);
DWORD off2 = *(DWORD*)(off1 + offsets[1]);
DWORD off3 = *(DWORD*)(off2 + offsets[2]);
DWORD off4 = *(DWORD*)(off3 + offsets[3]);
DWORD off5 = *(DWORD*)(off4 + offsets[4]);
cout << "Value: " << off5 << endl;
