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。

参考:http://support.microsoft.com/?scid=kb%3Ben-us%3B164501&x=4&y=12

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;
}

这段代码在vista,win7下不能成功,需要改进,参考:http://bbs.pediy.com/showthread.php?t=101469&highlight=Vista+Win7+CreateRemoteThread

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。

//0、分配非OS的加载函数
StackReserve = 0x1000;
ret = ZwAllocateVirtualMemory(hProcess,
/*&stack.ExpandableStackBottom*/(PVOID*)&pBaseThreadThunk,
0,
&StackReserve,
MEM_COMMIT,
PAGE_EXECUTE_READWRITE);
if (ret >= 0x80000000)
{
//失败

goto myCreateRemoteThreadRet;
//end
}
ret = ZwWriteVirtualMemory(hProcess,

}

//1、准备堆栈

ret = ZwAllocateVirtualMemory(hProcess,
/*&stack.ExpandableStackBottom*/(PVOID*)&Stack,

}

InitialTeb.AllocatedStackBase = (PVOID)Stack;
InitialTeb.StackBase = (PVOID)(Stack + StackReserve);

/* Update the Stack Position */
Stack += StackReserve - StackCommit;

Stack -= 0x1000;

/* Allocate memory for the stack */
ret = ZwAllocateVirtualMemory(hProcess,
(PVOID*)&Stack,
0,
&StackCommit,
MEM_COMMIT,
PAGE_READWRITE);
if (ret >= 0x80000000)
{
//失败

goto myCreateRemoteThreadRet;
//end
}
TRACE("OK myCreateRemoteThread:ZwAllocateVirtualMemory 2 0x%08x\n",Stack);
InitialTeb.StackLimit = (PVOID)Stack;


StackReserve = 0x1000;
ret = ZwProtectVirtualMemory(hProcess, (PVOID*)&Stack, &StackReserve, PAGE_READWRITE | PAGE_GUARD, &x);
if (ret >= 0x80000000)
{

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;
//end
}
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。

参见:http://msdn.microsoft.com/en-us/library/dd744762(v=vs.85).aspx

 

5.ShellExecuteHooks方式:

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


6.输入法注入:http://code.google.com/p/windows-config/wiki/Win32IME


7.lsp,SPI过滤注入网络进程:http://www.vckbase.com/document/viewdoc/?id=643

 http://www.vckbase.com/document/viewdoc/?id=808

 

8.BHO。

 

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
