VB 远线程注入技术 屏蔽 Ctrl+Alt+Del

在NT平台下，用户登陆是使用Winlogon和GINA——Graphical Identification and Authentication，意思是图形化的身份认证。Winlogon是Windows系统的一部分，它专门提供交互式登陆支持，而GINA则是Winlogon用来实现认证的一个DLL——这个DLL就是msgina.dll。WlxInitialize、WlxActivateUserShell便是其中输出，当然不知这两个，还有别的。前者进行自身的初始化，后者激活用户的外壳程序。Windows就是用这个DLL来实现用户名+口令的身份认证的，但是开发人员可以用自己的GINA代替msgina.dll。例如，实现智能卡、视网膜扫描仪、DNA检查等等认证机制来代替输入用户名+口令形式的身份检查。 下面的表格中列出了与GINA有关的全部函数。其中有一个是WlxLoggedOnSAS，当按下Ctrl+Alt+Del 键时，Winlogon便调用这个函数。

（表一）GINA 函数一览表 函数描述
WlxActivateUserShell激活用户外壳程序
WlxDisplayLockedNotice允许GINA DLL 显示锁定信息
WlxDisplaySASNotice当没有用户登陆时，Winlogon调用此函数
WlxDisplayStatusMessageWinlogon 用一个状态信息调用此函数进行显示
WlxGetConsoleSwitchCredentialsWinlogon调用此函数读取当前登陆用户的信任信息，并透明地将它们传到目标会话
WlxGetStatusMessageWinlogon 调用此函数获取当前状态信息
WlxInitialize针对指定的窗口位置进行GINA DLL初始化
WlxIsLockOk验证工作站正常锁定
WlxIslogoffOk验证注销正常
WlxLoggedOnSAS用户已登陆并且工作站没有被加锁，如果此时接收到SAS事件，则Winlogon 调用此函数
WlxLoggedOutSAS没有用户登陆，如果此时收到SAS事件，则Winlogon 调用此函数
WlxLogoff请求注销操作时通知GINA DLL
WlxNegotiate表示当前的Winlogon版本是否能使用GINA DLL
WlxNetworkProviderLoad在加载网络服务提供程序收集了身份和认证信息后，Winlogon 调用此函数
WlxRemoveStatusMessageWinlogon 调用此函数告诉GINA DLL 停止显示状态信息
WlxScreensaverNotify允许GINA与屏幕保护操作交互
WlxShutdown在关闭之前Winlogon 调用此函数，允许GINA实现任何关闭任务，例如从读卡器中退出智能卡
WlxStartApplication当系统需要在用户的上下文中启动应用程序时调用此函数
WlxWkstaLockedSAS当工作站被锁定，如果接收到一个SAS，则Winlogon 调用此函数


在默认情况下，GINA显示登陆对话框，用户输入用户名及口令。所以要想屏蔽掉Ctrl+Alt+Del，则可以写一个新的MyGina.dll，其中提供接口调用msgina.dll的函数WlxLoggedOnSAS，从而实现Ctrl+Alt+Del屏蔽。或者编写一个键盘驱动程序来实现。
　　NT系统允许使用我们自己的 GINA，因此，我们只要写一个这样的DLL，当然其它无关的函数我们可以转调用原GINA库中的函数，只处理WlxLoggedOnSAS这个函数。在此函数中可以结合原子操作，有条件的屏蔽Ctrl+Alt+Del，即如果某个（当然是你规定的）原子存在，你就返回 WLX_SAS_ACTION_NONE,　将将屏幕切换到应用程序桌面,从而好像屏蔽掉CTRL+ALT+DEL ，因此屏幕会闪一下，呵呵。具体的实现就我就不列出来了，毕竟不是本文的主要目的，而且网上大把参考代码的。如何安装这个DLL，也请自个到网上找，蛮多的。
三、不完美解决方案的另类实现
　　这个方法是我根据上面的原理再改进的，解决它的安装不方便的地方。不过也引出很多弊端。具体实现就是使用进程内存读写函数，以及虚拟内存管理函数，动态修改WinLogon进程中GIAN的函数。如果打开WinLogon进程在下面有讨论，至于如何定位函数及如何读写内存，自个去找资料吧。
四、完美的解决方案
　　本来用键盘驱动程序能完美解决的，可未免也杀鸡用牛刀，场面搞大了点。其实当你登录后，Winlogon创建一个新的桌面并调用Explorer。，而Winlogon则在另一个名为Winlogon的桌面中，也就是说，NT至少有一个桌面，就是你登录前看到的那个，（题外话：所以写个虚拟桌面工具，就难不倒你啦）。而Ctrl+Alt+Del对系统而言，也不过就是个热键罢了，只是它被定位到Winlogon桌面中去了，同样，它也必然有一个窗口负责处理这个热键消息的，因此，解决方案就出来，如果我们可找到这个窗口并子类化它，呵呵，不就...。（使用我提供的ShellCode代码，在我的电脑上有枚举出Winlogon桌面的四个窗口，其中有一个名为SAS window的窗口，其它是什么IME啦，等等，猜都能猜出啦，SAS windows应该就是啦）。因为我们要子类化WinLogon桌面中的窗口，别无选择的我们应该使用远程线程了，本文使用的是将所有代码注入到WinLogon进程中去，而不是远程挂接DLL的方式，这样在你开发程序过程中，无需任何第三方文件了。（这应该是你乐意的）
　　用文字描述，还真会难倒我，我们程序员用代码交流就是最好的语言，我起初的开发语言使用的是Win32ASM，之后有改写成VB版的，下面就列出VB版的代码，毕竟高级语言的代码能被大众所阅读。

?? | ================================ |
?? | |
?? | Usage: |
?? | Call LockKeyboard(T | F ) |
?? | 返回: True 成功;False 失败 |
?? | |
?? | Call GetKeyboardState |
?? | 返回: True 已锁定 |
?? | |
?? | |
?? | 实现原理： |
?? | 锁定 Ctrl+Alt+Del 使用远程线程、代码注入及子类化技术 |
?? | 其它键盘消息使用普通钩子技术 |
?? | |
?? | 本模块向 VB 程序员展示远程线程、代码注入等似乎被列入 |
?? | 只有Delphi、VC程序员才可能使用的技术，同时目前诸多木马 |
?? | 也同样大量使用这些技术。注入的方式比 Dll 钩入更加隐蔽。 |
?? | 注入后无进程、无文件。 |
