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:

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。

    //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。

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

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
