PEB、TEB详解
PEB
PEB中文名为进程环境块，里面存储了像映像加载程序、堆管理器以及其他windows组件需要从用户
模式访问的信息。在介绍PEB之前我们先来看一下进程内部的结构，以此来更好的了解PEB。
每个windows进程都可以用一种执行体进程(EPROCESS)进程来表示。EPROCESS及其大部分相关数据
结构都位于系统地址空间中。唯一的例外就是PEB，它位于用户地址空间中。对于每个执行了的
windows程序的进程，windows子系统进程(Csrss)维护了名为CSR_PROCESS的平行结构，另外
windows子系统(win32k.sys)的内核模式部分还为每个进程维护了名为W32PROCESS的数据结... | pdf |

我的CS笔记之- In-memory Evasion 4-5
0x00 前言
In-memory Evasion 4-5其中包含了威胁模拟的介绍，大致意思就是通过修改c2profile模仿真实APT的样
本会产生的特征行为等，也不是百分百模拟，就是模拟了一下yara规则中的静态特征，感兴趣的小伙伴
自行学习，我就不做笔记了。除了威胁模拟，视频中还介绍了cs3.11引入 的一些内存对抗新功能主要是
Module Stomping和cleanup这2个功能。这里不由感叹一句，自从CS被卖了以后的，更换了老大以
后，更新越来越不行了，还开始搞java代码混淆，class完整性校验。多把精力花在怎么进化CS上吧，
