无论我在哪里查看通过CreateRemoteThread进行注入(inject)的方法都是相同的,但是获取进程ID的方法并不相同。我的函数将返回正确的进程ID,对此我不感兴趣,因此我将作废该部分除外,仅包括实际注入(inject)。

我只是在学习DLL注入(inject),并尝试在notepad.exe上。如果注入(inject)有效,则记事本的标题将从“无标题-记事本”更改为“已挂钩”。

#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可以使用他人的注入(inject)器,但我不明白为什么...
实际上,它与注入(inject)器位于同一目录中。

最佳答案

我发现了问题...我感到很愚蠢。
任何有类似问题的人:使用绝对路径,而不要使用相对路径。

我变了

#define DLL_NAME "injectme.dll"


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