原标题:Reading a process memory

我正在尝试使用ReadProcessMemory() API函数读取控制台程序的进程内存。

www.un.org/Depts/DGACM/index_spanish.htm 增订法典:

    HWND hWnd = FindWindow(NULL, "Read Memory Window");
    DWORD ProcessId;
    ProcessId = GetProcessId(hWnd);
    GetWindowThreadProcessId(hWnd, &ProcessId);
    HANDLE hProcess = OpenProcess(PROCESS_VM_READ,FALSE, ProcessId);

    SIZE_T NumberOfBytesRead;
    CHAR Buffer[128] = {0};
    dwAddr = 0x0012FD6C; //address of array to get
    BOOL sucess = ReadProcessMemory(hProcess, &dwAddr, &Buffer, 128, &NumberOfBytesRead);

在运行该程序并读取数组的程序时,我会得到空值和垃圾值。

最佳回答

您正在使用固定地址,这通常是一个非常糟糕的想法,尤其是现在Windows Vista和Windows 7使用ASLR,即使是基于固定地址的模块也是不安全的(即使没有ASLR,也是不安全的,因为图像可以由于各种原因而被重新分配)。

此外,那个地址看起来非常可疑,你是怎么得出那个地址的?而且,它是否被正确地调整为虚拟地址,而不是相对地址?

最后但最重要的是,您不应该像您所做的那样传递地址和缓冲区,应该这样传递:

BOOL sucess = ReadProcessMem或者y(hProcess, (LPVOID)dwAddr, &Buffer[0], 128, &NumberOfBytesRead);

或者

BOOL sucess = ReadProcessMem或者y(hProcess, (LPVOID)dwAddr, Buffer, 128, &NumberOfBytesRead);
