用Visual studio2012在Windows8上开发内核中隐藏进程

最后更新于:2022-04-01 10:27:57

在Windows NT中,80386保护模式的“保护”比Windows 95中更坚固,这个“镀金的笼子”更加结实,更加难以打破。在Windows 95中,至少应用程序I/O操作是不受限制的,而在Windows NT中,我们的应用程序连这点权限都被剥夺了。在NT中几乎不太可能进入真正的ring0层。  在Windows NT中,存在三种Device Driver:   1.“Virtual device Driver” (VDD)。通过VDD,16位应用程序,如DOS 和Win16应用程序可以访问特定的I/O端口(注意,不是直接访问,而是要通过VDD来实现访问)。   2.“GDI Driver”,提供显示和打印所需的GDI函数。   3.“Kernel Mode Driver”,实现对特定硬件的操作,比如说CreateFile, CloseHandle (对于文件对象而言), ReadFile, WriteFile, DeviceIoControl 等操作。“Kernel Mode Driver”还是Windows NT中唯一可以对硬件中断和DMA进行操作的Driver。SCSI 小端口驱动和 网卡NDIS 驱动都是Kernel Mode Driver的一种特殊形式。 Visual studio2012与Windows8带来格外不同的新体验 1.启动Vs2012 ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-04-01_56fdf15192479.png) 2.看见满目的驱动开发模板 ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-04-01_56fdf151a72a9.png) 3.选择一个驱动模式,有内核模式与用户模式两种的驱动 ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-04-01_56fdf151e0f15.png)   4.创建一个驱动程序,KMDF DriverMVP ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-04-01_56fdf152053f8.png)   5.我们选择的是内核模式的驱动程序,下面是创建成功后的界面,分别是驱动程序本身,与驱动安装包 ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-04-01_56fdf15221ca7.png) 6.按下F5,选择驱动编译,   ![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-04-01_56fdf15236a2b.png) 插入下列代码实现内核隐藏进程 头文件 ~~~ #ifndef DBGHELP_H #define DBGHELP_H 1 #include <ntifs.h> /************************************************************************/ /* 重量级结构的申明 */ /************************************************************************/ typedef struct _HANDLE_TABLE { ULONG Flags;
