因为公司经常会有批量⾃动化测试的需求，所以之前⽤Python写了⼀套类似于群控的⼿机
调度系统。
⾸先想到的第⼀个问题是如何使⽤ADB控制⼿机；
⼀开始我写了⼀个 pyadbhelper 公共类，内容是使⽤ os.system 来调⽤ adb ，并且使
⽤ -s 参数来选择操作的设备。
但实际上这个⽅案很不稳定，因为 adb 的代码⾥既包含 server 端⼜包含 client 端，有时候
莫名其妙的就会把 server 端重启了(不同的环境有很多原因)。 因为是多线程操作，所以⼀
旦重启那么其他线程有可能正在进⾏ push pull 等操作就直接被中断导致任务失败。
换⼀种思路，就是⽤ python 实现⼀个 cl... | pdf |

针对域证书服务的攻击（2）- ESC2
0x00 前言
在ESC1的分析中我们遇到了一个问题，就是Certify这个工具带了2个DLL，很不方便，刚好今天看
twitter看到这么一个项目，https://github.com/CCob/dnMerge，使用NuGet搜dnMerge加入到项目
中，再release生成，就能编译成一个EXE了，很是简单。需要注意的就是只有release生成可以用，
debug是不能用的。
第二件事是一个题外话，我由于本地网络问题，我环境域控修改了IP，导致域中机器Ping域控域名的时
候返回127.0.0.1。这是我没有按照正规流程修改域控IP，细节看https://www.huaweicloud.... | pdf |

我的CS笔记之- In-memory Evasion 3
0x00 前言
前2部分，讲了侦测手法、CS payload的加载细节，这一部分主要讲怎么逃逸了，主要是使用CS自身的
C2profile来改变payload的加载行为。目前看来这些对抗手段已经是标配了，攻防对抗是一个水涨船高
的过程，标配都没搞好，天天去搞更强的对抗，就有点浮夸，我们一步一步来。

在In-memory Evasion 3中逃逸主要还是围绕着In-memory Evasion 1中的3个部分展开：
