wow32注入64位进程

转载地址：http://www.cnblogs.com/lanrenxinxin/p/4821152.html

在之前写注入都是32位exe文件注入32位dll到32位exe文件中，或者都是64位。但是之前看到关于32位进程注入64位进程的方法，将学习笔记记录下来。

之前的文章：注入小结

我们需要借助GitHub上的开源库rewolf-wow64ext 这个库的目的就是让运行在Wow64环境中的x86应用程序可以直接调用x64下ntdll.dll中的Native API。通过这个开源项目我们大致可以知道：

    ①在x64下的进程，不管是32位或者是64位，实际上都映射了两个地址空间，一个是32位，一个是64位。相当于一个进程的两种工作模式，而且这两种工作模式是可以进行切换的;

    ②Wow64进程中的r12寄存器指向64位的TEB结构(TEB64);

    ③每个32位进程都会加重ntdll32.dll和ntdll.dll模块。其中ntdll.dll是64位模块，我们可以将进程的32位模式改为64位模式，然后再去操作64位进程。

新增：

原因：

32位进程难以注入DLL进64位进程是由于两个进程内LoadLibrary的地址不同，32位进程无法知道64位进程的LoadLibrary函数地址。使用wow64ext这个库在Wow64环境下可以让32位进程获取到64位的ntdll.dll的导出函数（得到的地址与64进程的地址是一样的）。

具体的操作：

    ① 进程的32位模式改成64位模式

#define X64_Start() X64_Start_with_CS(0x33)#define X64_End() X64_End_with_CS(0x23)

 在wow64ext中对x64 api进程调用时，使用X64_Start_with_CS(0x33)设置进程的'运行模式"为64位。

#define EMIT(a) __asm __emit (a)#define X64_Start_with_CS(_cs) \    { \    EMIT(0x6A) EMIT(_cs)                         /*  push   _cs             */ \    EMIT(0xE8) EMIT(0) EMIT(0) EMIT(0) EMIT(0)   /*  call   $+5             */ \    EMIT(0x83) EMIT(4) EMIT(0x24) EMIT(5)        /*  add    dword [esp], 5  */ \    EMIT(0xCB)                                   /*  retf                   */ \    }#define X64_End_with_CS(_cs) \    { \    EMIT(0xE8) EMIT(0) EMIT(0) EMIT(0) EMIT(0)                                 /*  call   $+5                   */ \    EMIT(0xC7) EMIT(0x44) EMIT(0x24) EMIT(4) EMIT(_cs) EMIT(0) EMIT(0) EMIT(0) /*  mov    dword [rsp + 4], _cs  */ \    EMIT(0x83) EMIT(4) EMIT(0x24) EMIT(0xD)                                    /*  add    dword [rsp], 0xD      */ \    EMIT(0xCB)                                                                 /*  retf                         */ \    }

可以看到主要是借助retf将CS寄存器的值设置为0x33。这里提一下题外话，可以百度一下ret，iret和retf三者之间的区别。

②获得目标函数所在模块(ntdll.dll)在x64模式下的加载基地址：

#define X64_Push(r) EMIT(0x48 | ((r) >> 3)) EMIT(0x50 | ((r) & 7))DWORD64 getTEB64(){    reg64 reg;    reg.v = 0;       X64_Start();    // R12 register should always contain pointer to TEB64 in WoW64 processes    X64_Push(_R12);    // below pop will pop QWORD from stack, as we're in x64 mode now    __asm pop reg.dw[0]    X64_End();    return reg.v;}

关于TEB的获得是通过r12-->TEB64--->PEB--->LDR匹配到ntdll.dll来找到ntdll.dll的加载基地址。

③解析PE结构找到目标函数在"x64模式"下的真实地址(GetProcAddr())。

④通过函数地址调用"x64模式"下的目标函数。这里要注意x64函数调用约定的改变，前4个参数通过rcx,rdx,r8,r9来传递，之后通过堆栈传递。X64Call()已经封装好了。

接下来我们可以开始实际的工作了。

NTSTATUSNTAPIRtlCreateUserThread(    _In_ HANDLE processHandle,    _In_ SECURITY_DESCRIPTOR* securityDescriptor,    _In_ BOOLEAN createSuspended,    _In_ ULONG stackZeroBits,    _Inout_opt_ size_t* stackReserved,    _Inout_opt_ size_t* stackCommit,    _In_ const void* startAddress,    _In_ void* startParameter,    _Inout_ HANDLE* threadHandle,    _Inout_opt_ CLIENT_ID* clientID    );

NTSTATUSNTAPILdrLoadDll(    _In_opt_ PWSTR SearchPath,    _In_opt_ PULONG LoadFlags,    _In_ PUNICODE_STRING Name,    _Out_opt_ PVOID *BaseAddress    );

VOIDNTAPIRtlExitUserThread(    _In_ NTSTATUS Status    );

不同于之前利用CreateRemoteThread()来创建线程。因为CreateRemoteThread()是由Kernel32.dll导出的，wow64ext这个库只针对ntdll.dll(同理LoadLibrary也不能调用)。所以采用ntdll中未文档化的RtlCreateUserThread()来创建远程线程，LdrLoadDll()加载dll，在远程线程中调用RtlExitUserThread()终止远程线程。

关于Windows x64的学习，《Windows Internals》（中文译版《深入解析Windows操作系统》，潘老师译的）不错。顺便吐槽下学校把那么多的好书都放在阅览室，只能看，不能借，好多全新的书上都是灰！

32位注入32位 64位注入64位进程代码如下：

HANDLE hProcess = OpenProcess(PROCESS_CREATE_THREAD | PROCESS_QUERY_INFORMATION | PROCESS_VM_OPERATION | PROCESS_VM_WRITE | PROCESS_VM_READ, FALSE, nPID);if (hProcess != NULL){HANDLE hThread;WCHAR   szLibPath[_MAX_PATH] = {0};WCHAR   szReadLibPath[_MAX_PATH] = {0};void*  pLibRemote = 0;DWORD  hLibModule = 0;HMODULE hKernel32 = ::GetModuleHandle(L"Kernel32");if (!::GetSystemDirectory(szLibPath, _MAX_PATH))return FALSE;wcscat(szLibPath, L"\\test.dll");pLibRemote = ::VirtualAllocEx(hProcess, NULL, sizeof(szLibPath), MEM_COMMIT, PAGE_READWRITE);if (pLibRemote == NULL)return FALSE;::WriteProcessMemory(hProcess, pLibRemote, (void*)szLibPath, wcslen(szLibPath)*sizeof(WCHAR), NULL);//::ReadProcessMemory(hProcess, pLibRemote, (void*)szReadLibPath, wcslen(szLibPath)*sizeof(WCHAR), NULL);LPTHREAD_START_ROUTINE LoadLibAddr = (LPTHREAD_START_ROUTINE)GetProcAddress(hKernel32, "LoadLibraryW");hThread = ::CreateRemoteThread(hProcess, NULL, 0,LoadLibAddr,pLibRemote, 0, NULL);if (hThread != NULL){::WaitForSingleObject(hThread, INFINITE);::GetExitCodeThread(hThread, &hLibModule);::CloseHandle(hThread);}}
