实战攻防演习之
蓝队视角下的防御体系构建

前 言
网络实战攻防演习，是新形势下关键信息系统网络
安全保护工作的重要组成部分。演习通常是以实际运
行的信息系统为保护目标，通过有监督的攻防对抗，
最大限度地模拟真实的网络攻击，以此来检验信息系

2016年以来，在国家监管机构的有力推动下，网
络实战攻防演习日益得到重视，演习范围越来越广，
演习周期越来越长，演习规模越来越大。国家有关部
门组织的全国性网络实战攻防演习从2016年仅有几家
参演单位，到2019年已扩展到上百家参演单位；同时

做红队你需要学习“如何挖掘战壕”（一）
0x00 前言
看到红队和战壕，相信做红队或者蓝军的同学应该知道我想聊什么了？今天和大家聊一聊红队的基础设
施。
19年的时候为了准备一个PPT，系统的梳理了下红队的基础设施，现在写出来算是抄冷饭了，希望对大
家依旧有用。我曾经大言不惭的说过一句话“在红队行动中，完善的基础设施是成功的一半”。虽有夸
张，却无不当。在这儿做个形象的比喻，搭建基础设施，类似于打仗前挖的战壕。战壕不仅是个人掩
体，还是部队作战、输送和补给的场地。战壕置于战争的作用，就是基础设施置于红队行动的作用。对
军事有兴趣的同学可以百度“如何挖掘战壕”。回归正题，所谓的红队的基础设施具体的是什么？下文中

Go默认编译会自带一堆信息，通过这些信息基本可以还原Go的源码架构，

文章末尾提供了一款工具，可以一键消除Go二进制中的这些敏感信息。

今年职业上有了一点小变动，从一个攻击者变成了一个防御者。于是想把作为攻击者的一些想法写下来
和大家交流。
某大型攻防演练暂告段落，攻击者们在弹冠相庆之后纷纷借着五一休假了。攻击方投入越来越大，攻击
模式的体系化、流程化；攻击工具工程化、实战化，以肉眼可见的速度发展着。作为一个曾经的攻击
者，内心是非常激动的。虽然已是局外人，但每每听到攻击方的故事，还是会热血沸腾。
我眼中的红队
曾经和朋友聊什么是红队？怎么做一只符合国情的红队？也阅读过很多国外红队报告，一度被各种高超
的红队技巧迷花了眼。都说红队是在模仿APT攻击，但在前公司有幸参加“金链熊”分析后。我意识到红队
如果是以模仿APT的路子走是不对的。红队... | pdf |
Java安全之反序列化回显研究
0x00 前言
续上文反序列化回显与内存马，继续来看看反序列化回显的方式。上篇文中其实是利用中间件中存储的
Request 和 Response 对象来进行回显。但并不止这么一种方式。
0x01 回显方式
1. 中间件回显
2. defineClass
3. Linux描述符回显
4. RMI绑定实例
5. URLClassLoader抛出异常
6. 写文件css、js
7. dnslog
defineClass异常回显

针对域证书服务的攻击（4）- ESC4
0x00 前言
ESC4叫做“Vulnerable Certificate Template Access Control”，其实是弱ACL的证书模板会导致域提权。
写完ESC1-ESC3，ESC4由于白皮书没有比较详细的过程，并且我本地域环境出了点问题，就搁置到现
在。但是国庆的时候，看见国外的研究员发布了一篇关于ESC4的文章：https://github.com/daem0nc0
re/Abusing_Weak_ACL_on_Certificate_Templates，减少了我很多工作量。我们知道每个模板都有自己

攻击内⽹的另类⽅式——host碰撞实践指南
清⽔川崎@滴滴SSTG
0x00.前⾔
在当前的攻防实战当中，想要突破⽬标边界进入内⽹的⽅式无非有以下⼏种⽅式：
1.RCE/RCI(远程代码执⾏/远程命令注入)
2.VPN弱⼝令
3.SSRF漏洞
4.SQLI
5.⽂件上传
6.物理攻击/社⼯钓⻥
但是有⼀种依靠⻓期信息收集才能提升攻击成功率的⽅式往往被忽略，那就是host
碰撞。
0x01.本质
host碰撞这种攻击⽅式本质上是nginx配置不当容易产⽣的安全问题。 nginx⼀般⽤
于做外⽹代理，配置也比较⽅便，但是配置不当的时候会产⽣⼀些安全问题。其中
