一，本地内核调试( lkd )：

管理员权限启动windbg，ctrl + k --> Local

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70][]

二，查看进程数据结构

1. 启动计算器

2. !process 0 0 列出系统内的所有进程

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 1][]

3. dt \_EPROCESS 88270030 (查看calc.exe 的EPROCESS结构)

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 2][]

4.!process 88270030 (查看calc.exe 的关键信息)

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 3][]

5. !token b1430a38 (查看calc.exe 的token信息)

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 4][]

6.查看peb （内核模式下，先设置隐式进程）

.process 88270030 （设置calc.exe 为隐式进程）

![2019060419042856.png][]

dt \_PEB 7ffde000 （查看calc.exe peb）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 5][]

7.!handle （查看calce.exe 句柄表 在calce.exe 进程环境）

.![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 6][]

8. !process 4 0 （查看system进程）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 7][]

9. 查看 idle 进程

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 8][]

二 ，双机调试（kd） 环境配置：[https://blog.csdn.net/huanongying131/article/details/90740286][https_blog.csdn.net_huanongying131_article_details_90740286]

1.查看双重错误 任务门（软件调试 p301）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 9][]

2.查看当前任务门(tr)

![20190605112346140.png][]

3.产看中断描述表(idt)

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 10][]

三、UefSndThrd.exe练习（12章）

1.ctrl+e 打开执行文件

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 11][]

2.设置符号路径，源文件路径：

![20190606145250162.png][]

3.下bp断点

![20190606145336482.png][]

4.g 执行

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 12][]

5.继续：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 13][]

6.从中可以看出：

主函数插入了一层异常（\_XcptFilter）

四、dump练习

1.用everyting 搜.dmp 发现一堆 tim的dump OK *选一个来练习一下*

*2.ctrl+d*

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 14][]

3.随便选一个

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 15][]

4. .ecrx （显示异常环境记录，重要的是 该指令还会却换到发生异常的线程环境

比如（~ （线程号）s .process EPROCESS地址） 都是确换环境，有了环境 kn 这些指令才能根据环境获取信息）

![20190606155224614.png][]

5. kv 查看栈回溯

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 16][]

五、蓝屏dump练习

1.本系统C:\\Windows 目录下刚好有个MEMORY.dmp文件 直接用它

2.ctrl + d 打开dmp文件

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 17][]

2. BugCheck 7F （从 debugger.chm（windbg帮助文档）搜索 Bug Check 0x7F）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 18][]

3. \{8, 807ca750, 0, 0\}

第一个参数 8

![20190606163220270.png][]

4. 照着文档的流程 练习一下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 19][]

5.**!analyze**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 20][]

6. kv （上面 可以知道 是哪个驱动导致的（Hooksys.sys） 看一下栈回溯 (分析一下驱动的哪一部分导致的））

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 21][]

7. .tss 0x28 查看任务状态段 （由上图可知是一个 tass gate 中断）

![20190606165916996.png][]

8. kv (上图 可以看出蓝屏是 nt!MiAllocatePoolPages+0x12 看一下哪一部分调到这里的）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 22][]

9. .thread !thread （查看线程信息， 蓝屏环境是 当前线程 当前进程）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 23][]

10. .process !process （查看当前进程）

![20190606171844666.png][]

11. **!analyze -v（一步到位）**（1--8 很繁琐 但刚开始分析 需要 理解原理 分析过程）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 24][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 25][]

FAILURE\_BUCKET\_ID: 0x7f\_8\_Hooksys+1b2f6 BUGCHECK\_STR: 0x7f\_8

UNEXPECTED\_KERNEL\_MODE\_TRAP (7f) Arg1: 00000008, EXCEPTION\_DOUBLE\_FAULT

12. ln ( 查看最后跳转 LAST\_CONTROL\_TRANSFER: from 83cabafe to 83d3247a）

![20190606173808297.png][]

ExpAllocateBigPool ---> MiAllocatePoolPages

六. TEB （24章）

打开计算器calc.exe，windbg F6 -->附加到calc.exe

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2h1YW5vbmd5aW5nMTMx_size_16_color_FFFFFF_t_70 26][]
