四、进程线程

4.1.WRK

1.Project-->New Project-->选择wrk目录-->ok

2.Add and Remove Project Files--->选中四个文件-->Add Tree

3.搜索

4.2.KPCR

kpcr:cpu核控制块,cpu一个核一个kpcr结构

fs=0x30 在内核中的时候,指向的是kpcr结构

fs=0x3b 在应用层的时候,指向的是当前线程的TEB

4.3.函数类型

Windows是微内核,分内核结构和执行体结构

  • 内核结构:只在内核中使用(KPROCESS属于内核结构)

  • 执行体结构:专门用于和R3打交道 (EPROCESS属于执行体)

函数类型

  • Ex:执行体函数,进程、线程、链表、对象属性、赋值、取值、加锁相关

  • Ke:内核函数,大部分是导出

  • Ki:微内核函数,不导出,内部自己使用。进程、线程、cpu、调度相关

  • Ps:执行体函数,进程、线程相关

  • Mm:内存相关函数,一般导出

  • Mi:内存相关函数,Mm函数底层就是调用Mi,不导出

  • Io:文件、设备相关,导出

  • CC:文件缓存

  • Rtl:导出函数,一般是运行库,字符串操作等

  • Zw:SSDT,但是Zw不需要修改线程的先前模式

  • Nt:Zw函数会调用到Nt,本身Zw函数不实现功能

  • CM:注册表

  • hal:硬件函数

  • Ob:对象管理器,句柄,创建内核对象,查询内核对象等

  • Pnp:电源管理

  • Psp:执行体函数,进程、线程。Ps函数实现复杂功能的时候,都是调用Psp
