Ring3下Dll注入方法整理汇总

Ring3下Dll注⼊⽅法整理汇总
1.dll劫持，粗略整理了下，可以劫持的dll有(持续更新)：
lpk.dll、usp10.dll、msimg32.dll、midimap.dll、ksuser.dll、comres.dll、ddraw.dll
以lpk为例，在win7下由于lpk被加⼊KnownDLLs且该注册表值不可修改，使得lpk强制从系统⽬录加载，
不过可以将lpk.dll加⼊ExcludeFromKnownDlls来解决，具体可以创建⼀个lpk.reg⽂件：
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager]
"ExcludeFromKnownDlls"=hex(7):6c,00,70,00,6b,00,2e,00,64,00,6c,00,6c,00,00,00,\
00,00
成功导⼊后需要重新启动电脑才能⽣效。

另外win7下的lpk在编写⽅⾯需要注意：
WIN7有的程序调⽤LPK.DLL的LpkInitialize输出函数在LPK的初始化前⾯.
要在LpkInitialize这个函数中加⼊⼀些处理,并且这部分代码不能加密.
因此为了兼容各个系统，可以在DllMain和LpkInitialize⾥均做判断，如果没有初始化就进⾏初始化。

下⾯贴出完整代码：// lpk.cpp : Defines the entry point for the DLL application.

2.通过CreateRemoteThread创建远程线程。

XP以下使⽤代码：
BOOL WINAPI RemoteLoadLibrary(LPCTSTR pszDllName, DWORD dwProcessId)
{
// 打开⽬标进程
HANDLE hProcess = ::OpenProcess(
PROCESS_VM_WRITE|PROCESS_CREATE_THREAD|PROCESS_VM_OPERATION, FALSE, dwProcessId);
if(hProcess == NULL)
return FALSE;
// 在⽬标进程申请空间，存放字符串pszDllName，作为远程线程的参数
int cbSize = (::lstrlen(pszDllName) + 1);
LPVOID lpRemoteDllName = ::VirtualAllocEx(hProcess, NULL, cbSize, MEM_COMMIT, PAGE_READWRITE);
::WriteProcessMemory(hProcess, lpRemoteDllName, pszDllName, cbSize, NULL);
// 取得LoadLibraryA函数的地址，我们将以它作为远程线程函数启动
HMODULE hModule=::GetModuleHandle (_T("kernel32.dll"));
LPTHREAD_START_ROUTINE pfnStartRoutine =
(LPTHREAD_START_ROUTINE)::GetProcAddress(hModule, "LoadLibraryA");
// 启动远程线程
HANDLE hRemoteThread = ::CreateRemoteThread(hProcess, NULL, 0, pfnStartRoutine, lpRemoteDllName, 0, NULL);
if(hRemoteThread == NULL)
{
::CloseHandle(hProcess);
return FALSE;
}
::CloseHandle(hRemoteThread);
::CloseHandle(hProcess);
return TRUE;
}
我参考上⾯资料和代码，稍作整理使之编译通过并能使⽤，⽬标进程打开时最好使⽤PROCESS_ALL_ACCESS权限。

vista的较为简单些，只要修改⼀个内存⾥的数值，这⾥不再实现。

typedef struct _CLIENT_ID {

ret = ZwAllocateVirtualMemory(hProcess,

if (ret >= 0x80000000)
{

goto myCreateRemoteThreadRet;

}
TRACE("OK myCreateRemoteThread:ZwAllocateVirtualMemory 2 0x%08x\n",Stack);

if (ret >= 0x80000000)
{
//失败

goto myCreateRemoteThreadRet;
//end
}
/* Update the Stack Limit keeping in mind the Guard Page */
InitialTeb.StackLimit = (PVOID)((ULONG_PTR)InitialTeb.StackLimit - 0x1000);
//2、准备CONTEXT
// CONTEXT context = {CONTEXT_FULL};
ret = ZwGetContextThread(GetCurrentThread(),&context);
if (ret >= 0x80000000)
{
//失败
TRACE("Error IN myCreateRemoteThread ZwGetContextThread!\n");
goto myCreateRemoteThreadRet;
//end
}
context.Esp = (DWORD)InitialTeb.StackBase;
context.Eip = (DWORD)pBaseThreadThunk; //这⾥填写需要加载的地址，不过需要⾃⼰终结⾃⼰
context.Ebx = (DWORD)lpParameter;
//other init
//must
context.Eax = (DWORD)lpStartAddress;
context.Ecx = (DWORD)GetProcAddress(GetModuleHandle("ntdll.dll"),"RtlExitUserThread");//0x778B0859;/*win7*///0x77AEEC01;/*vista*/ //ntdll.RtlExitUserThread context.Edx = 0x00000000; //nouse
ret = ZwCreateThread(&hThread, THREAD_ALL_ACCESS, 0, hProcess, &cid, &context, &InitialTeb, TRUE);
if (ret >= 0x80000000)
{
//失败
TRACE("Error %d\n",GetLastError());
goto myCreateRemoteThreadRet;
}
if(lpThreadId)
{
*lpThreadId = (DWORD)cid.UniqueThread;
}
if (!(dwCreationFlags & CREATE_SUSPENDED))
{
ZwResumeThread(hThread, NULL);
}
myCreateRemoteThreadRet:
return hThread;
}
最后通⽤的使⽤⽅法是：
// 启动远程线程
HANDLE hRemoteThread = NULL;
OSVERSIONINFO svex = {sizeof(OSVERSIONINFO)};
GetVersionEx(&svex);
if( svex.dwMajorVersion<=5 ){
hRemoteThread = ::CreateRemoteThread(hProcess, NULL, 0, pfnStartRoutine, lpRemoteDllName, 0, NULL);
}else{
hRemoteThread = myCreateRemoteThread(hProcess, NULL, 0, pfnStartRoutine, lpRemoteDllName, 0, NULL);
}
3.通过SetWindowsHookEx安装钩⼦，如WH_CALLWNDPROC，WH_KEYBOARD，WH_MOUSE，WH_GETMESSAGE钩⼦可以实现全局注⼊。

SetWindowsHookEx(WH_MOUSE,(HOOKPROC)MouseProc,AfxGetInstanceHandle(),dwThreadId);
4.AppInit_DLLs⽅式：
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_DLLs注⼊到所有加载了user32.dll的进程。

win7下会被映射到：HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows，
并且需要设置LoadAppInit_DLLs为1时AppInit_DLLs才会被启⽤，默认为0。

例如在xp下创建⼀个.reg⽂件：
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows]
"AppInit_DLLs"="c:\\message.dll"
⼿动导⼊后是可以加载指定dll的，但是在win7下⾯就不⾏，通过该.reg⽂件操作的注册表⼦键路径并没有被重定向到
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows，
但是通过写代码的⽅式是成功的：
void LoadLibByAppInit_DLLs(LPCTSTR pszDllName,BOOL bInstall)
{
HKEY hKey = NULL;
DWORD dwRet = 0;
//win7下会被映射到：HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows
if ( RegCreateKeyEx(HKEY_LOCAL_MACHINE, _T("SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Windows"), 0, 0, 0, KEY_ALL_ACCESS, 0, &hKey, 0)!=ERROR_SUCCESS ){ return;
}
dwRet = RegSetValueEx(hKey,_T("LoadAppInit_DLLs"),0,REG_DWORD,(const BYTE *)&bInstall,sizeof(bInstall));
if ( bInstall ){
dwRet = RegSetValueEx(hKey,_T("AppInit_Dlls"),0,REG_SZ,(const BYTE *)pszDllName,lstrlen(pszDllName));
}else{
dwRet = RegSetValueEx(hKey,_T("AppInit_DLLs"),NULL,REG_SZ,NULL,0);
}
RegCloseKey(hKey);
}
在win7下还有⼀个值RequireSignedAppInit_DLLs，如果为1表⽰则只加载有签名的dll，默认为0表⽰不对dll进⾏验证。

5.ShellExecuteHooks⽅式：
local_machine\software\microsoft\windows\currentversion\Explorer\ShellExecuteHooks注⼊到explorer.exe进程。

9.输⼊表⽅式注⼊，原理就是为⽬标pe⽂件增加⼀个导⼊函数，这个导⼊的函数是在要注⼊的dll中。

这样当⽬标PE⽂件被加载时会由系统来完成它的导⼊库的装载⼯作，这样你的DLL就能被加载进去了。

可以使⽤类似DIYTools的PE⼯具来完成，代码我就不写了。

10.CreateProcess以挂起的⽅式创建⽬标进程，修改⼊⼝代码加载指定dll，恢复⼊⼝代码唤醒进程。

11.使⽤微软提供的detours库函数DetourCreateProcessWithDll创建进程并为进程加载指定dll，这个⽅法原理上就是上⾯的CreateProcess⽅法，只不过更简单更稳定了，拿来主义嘛。

12.通过DXG⽅式注⼊使⽤DirectX的进程，暂⽆资料。

13.RegisterUserApiHook。
