写一个注入进程后监视其文件读写操作的代码 用c语言

以下是一个简单的示例代码，它使用Windows API来注入进程并监视其文件读写操作。本示例只监视了一个文件，您可以根据自己的需要进行更改。

#include <windows.h>
#include <stdio.h>

// 监视的文件路径
#define FILE_PATH "C:\\test.txt"

// 定义回调函数
VOID CALLBACK FileIOCompletionRoutine(DWORD dwErrorCode, DWORD dwNumberOfBytesTransfered, LPOVERLAPPED lpOverlapped);

int main()
{
    // 获取要注入的进程句柄
    HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, 1234); // 进程ID为1234

    // 分配内存空间，存放要注入的代码
    LPVOID lpBaseAddress = VirtualAllocEx(hProcess, NULL, sizeof(FileIOCompletionRoutine), MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE);
    if (lpBaseAddress == NULL)
    {
        printf("VirtualAllocEx failed (%d)\n", GetLastError());
        return 1;
    }

    // 将要注入的代码写入分配的内存空间
    if (!WriteProcessMemory(hProcess, lpBaseAddress, &FileIOCompletionRoutine, sizeof(FileIOCompletionRoutine), NULL))
    {
        printf("WriteProcessMemory failed (%d)\n", GetLastError());
        return 1;
    }

    // 获取回调函数的地址
    LPTHREAD_START_ROUTINE lpStartAddress = (LPTHREAD_START_ROUTINE)lpBaseAddress;

    // 注入代码
    HANDLE hThread = CreateRemoteThread(hProcess, NULL, 0, lpStartAddress, NULL, 0, NULL);
    if (hThread == NULL)
    {
        printf("CreateRemoteThread failed (%d)\n", GetLastError());
        return 1;
    }

    // 等待注入的代码执行完毕
    WaitForSingleObject(hThread, INFINITE);

    // 关闭句柄
    CloseHandle(hThread);
    CloseHandle(hProcess);

    return 0;
}

VOID CALLBACK FileIOCompletionRoutine(DWORD dwErrorCode, DWORD dwNumberOfBytesTransfered, LPOVERLAPPED lpOverlapped)
{
    // 判断是否为文件读操作
    if (lpOverlapped->OffsetHigh == 0 && lpOverlapped->Offset == 0)
    {
        printf("File read operation detected\n");
    }

    // 判断是否为文件写操作
    if (lpOverlapped->OffsetHigh == 0 && lpOverlapped->Offset == 1)
    {
        printf("File write operation detected\n");
    }
    
    return;
}
