分享Win10 1903过TP的双机调试问题

栏目：Linux/apache问题时间：2019-11-23 16:35

差不多我用到的大部分代码都是从上面cv（Ctrl+c---->Ctrl+v）下来的

1、首先解决The context is partially valid. Only x86 user-mode context is available.

具体方式是hookKdpTrap

2、防止安全组件加载失败

SharedUserData->KdDebuggerEnabled = FALSE; //防止安全组件加载失败，SharedUserData这个是一个导出的全局变量直接写就行

3、XP会清零KdDebuggerEnabled

这里本来是打算做一个定时器，但是还是会导致TesNginx.Sycccccccccccccc出现蓝屏，所以只有手动的去修改

4、断链隐藏 kdcom，防止kdcom内存被清空导致和windbg通讯不了

5、XP会检测KdEnteredDebugger，如果是1就直接蓝屏

处理方式是让他去找其他位置(PUCHAR)KdEnteredDebugger + 0x30; //据暗中观察，+0x30 的位置恒为0

做完这些之后基本上就能够下断点了，但是其实还是有问题（由于hook了系统函数有一定的几率会触发109错误->PathGuard，一开始我也分不清楚，后来慢慢的也了解了）

之后放上一张过了图片

最后把代码也带上吧，.asm文件很简单简单的inlinhook就行了

#include <Ntifs.h>
#include <ntimage.h>
extern void debg();
//关闭写保护
KIRQL WPOFFx64(){
 KIRQL irql = KeRaiseIrqlToDpcLevel();
 UINT64 cr0 = __readcr0();
 cr0 &= 0xfffffffffffeffff;
 __writecr0(cr0);
 _disable();
 return irql;
}
//开启写保护
void WPONx64(KIRQL irql){
 UINT64 cr0 = __readcr0();
 cr0 |= 0x10000;
 _enable();
 __writecr0(cr0);
 KeLowerIrql(irql);
}
