微软AD如何定位域控

在搭建完域之后，先把域控启动后再启动客户机的机器的时候抓了⼀下包
在3-6条
1.client请求DNS服务器的ldap.tcp.dc._msdcs.loca.test.com的SRV记录
2.DNS服务器返回SRV⾥记录的服务、端⼝、 A记录。（192.168.1.200：389）
3.client拿到SRV⾥的值以后发送解析A记录的请求
4.DNS服务器返回了解析的域名+IP地址

做红队你需要学习“如何挖掘战壕”（三）
0x00 前言
在前两篇的文章中，我们先是分析了红队基础设施架构，并指出构成的3大元素：ip和域名、C2工具、
前置器，然后我们在第二篇文章中针对ip和域名的选择做了分享。这是第三篇，我们将是分析C2工具，
这儿的C2工具主要使用的是CobaltStrike。CobaltStrike功能强大，此处仅分析和我们红队基础设施相关
的部分。
0x01 Payload加载流程
为什么红队基础设施要讲Payload加载呢？因为这涉及到Payload分段加载和放置位置的问题。如果
Payload使用分段加载一定要注意远程下载Payload的时候。Payload不一定是放置在TeamServer服务

Web 服务器安全
PHP 其实不过是 Web 服务器的一个模块功能，所以首先要保证 Web 服务器的安全。当然
Web 服务器要安全又必须是先保证系统安全，这样就扯远了， 无穷无尽。PHP 可以和各种
Web 服务器结合，这里也只讨论 Apache。非常建议以 chroot 方式安装启动 Apache，这样即
使 Apache 和 PHP 及其脚本出现漏洞，受影响的也只有这个禁锢的系统，不会危害实际系

说明
log4j2 与 log4j 属于不同项目，且二者的配置方式也存在差异， log4j 是通过
log4j.properties 来进行配置的，而 log4j2 是通过 xml 文件来进行配置的。
环境搭建
pom.xml
测试代码
在众多测试代码当中大家都是利用 Logger.error() 来触发漏洞但，根据 log4j2 的默认漏洞级别
trace<debug<info<warn<error<fatal ， error 和 fatal 两个级别的日志会打印到控制台，同
时也会触发漏洞，当然还可以通过配置文件获取动态级别两个方式调整。

用Golang编写 dll劫持的一些坑 (3)
源于知识星球的一个想法，利用一些已知的dll劫持的程序作为"模板",自动生成白加黑的程序。
我想用Golang编写劫持的dll，这样也方便可以做成在线平台。
我们的目标不是让它弹一个信息框，而是让它执行shellcode，并且使用一些hook技术保证白程序只加
载一个dll的同时不和后续的代码冲突 这需要我们编写一个通用的dll白加黑的劫持模板，当然dll加载模
式不同劫持的方式也不同。
我找到是vscode它的更新程序，也有它官方的签名
被劫持的dll在 inno_updater.exe 的导入表中，这种劫持可以叫它 pre-load ，我只用实现它的5个函数
就可以了。

TOC
概述
作者根据EQGRP公开资料进行研究分析，研究相关工具的开发实现和攻击防御思路。
因为木有找到NOPEN这个C2的Windows下的Beacon程序，所以找了一些资料，发现就是FB可
以进行Windows下的C2操作，虽然是个python程序，但是也好过于无。
所以决定查看当前的研究成果，整理一个环境，看看能不能与NOPEN进行联动？
FuzzBunch的中文翻译就是模糊测试工具集，用来对目标系统进行渗透。
基本信息
本次分析的代码，来自shadowbroker的爆料，经过网络接力，我们这里使用三好学生修改
