Question

无论我在哪里看到通过CreateRemoteThread注入的方法都是一样的，但抓取进程ID的方法不是......我的函数将返回正确的进程ID，我对此没有任何帮助，所以我将该部分取消，仅包括实际注射。

我只是学习DLL注入而且我正在尝试使用notepad.exe。如果注射工作，记事本的标题将从“无标题 - 记事本”变为“挂钩”。

#define DLL_NAME "injectme.dll"

.....

BOOL InjectRemoteThread(DWORD ProcessID)
{
    HANDLE RemoteProc;
    char buf[50]        =   {0};
    LPVOID MemAlloc;
    LPVOID LoadLibAddress;

    // Process ID does show correctly!
    WCHAR id[100];
    StringCbPrintf(id, 100, L"%d", ProcessID); // id contains the process ID... is confirmed in comparing ID shown in tasklist and the messagebox.
    MessageBox(NULL, id, L"Process ID", MB_ICONINFORMATION);
    // Process ID does show correctly!

    if ( !ProcessID )
    {
        MessageBox(NULL, (LPCWSTR)GetLastError(), L"An error occured", NULL);
        return 0;
    }
    RemoteProc          =   OpenProcess(PROCESS_VM_OPERATION | PROCESS_VM_WRITE | PROCESS_CREATE_THREAD | PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, ProcessID);
    if ( !RemoteProc )
    {
        MessageBox(NULL, (LPCWSTR)GetLastError(), L"An error occured", NULL);
        return 0;
    }
    LoadLibAddress      =   (LPVOID)GetProcAddress(GetModuleHandleA("kernel32.dll"), "LoadLibraryA");
    MemAlloc            =   (LPVOID)VirtualAllocEx(RemoteProc, NULL, strlen(DLL_NAME)+1, MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE);
    WriteProcessMemory(RemoteProc, (LPVOID)MemAlloc, DLL_NAME, strlen(DLL_NAME)+1, NULL);
    CreateRemoteThread(RemoteProc, NULL, NULL, (LPTHREAD_START_ROUTINE)LoadLibAddress, (LPVOID)MemAlloc, NULL, NULL);

    CloseHandle(RemoteProc);
    VirtualFreeEx(RemoteProc, (LPVOID)MemAlloc, 0, MEM_RELEASE | MEM_DECOMMIT);
    return 1;
}

DLL使用另一个人的注射器，但我不明白为什么...... 它确实与注射器位于同一目录中。

我发现了问题......我觉得很蠢。任何有类似问题的人：使用绝对路径而不是相对路径。

我改变了

#define DLL_NAME "injectme.dll"

要

#define DLL_NAME "C:\\Users\\Raikazu\\Documents\\Visual Studio 2012\\Projects\\Hooking\\Release\\injectme.dll"
