Windows10 x64 获取PEB表，并获取ntdll基址

本文主要是介绍Windows10 x64 获取PEB表，并获取ntdll基址，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

1.Windows通过TEB封装信息,TEB中包含PEB表,如图:

(站在看雪大佬巨人的肩膀上才能看得更远)

具体过程是从teb->peb->ldr->InInitializationOrderModuleList->dll模块基址,经过一系列的结构体偏移得到模块初始化装载顺序.

2.dt _TEB 可以看到PEB表偏移

可以从FullDllName特征遍历所有模块基址.

6.因此代码如下

.CODE

asm1 PROC
        ;mov rax,60h       ;TEB
		mov rax, gs:[60h]  ;PEB
		mov rax, [rax+18h] ;LDR
        mov rax, [rax+30h] ;InInitializationOrderModuleList or ntdll.dll
        ;mov rax,[rax]      ;_LDR_MODULE.InLoadOrderModuleList].Blink kernelbase.dll
        ;mov rax,[rax]      ;_LDR_MODULE.InLoadOrderModuleList].Blink kernel32.dll
        ;mov rax,[rax]
        ;mov rax,[rax]
        mov rax,[rax+10h]  ;DllBase
		RET
asm1 ENDP
 
END

所以加载的模块经过遍历链表就可以找到相应dll的基址.

7.实现如下
