title: 蚁剑改造计划之支持内存马
author: yzddmr6
blog: yzddmr6.tk
前言
最近因为各种事情太忙了，博客也很久没有更新了。今天暂且先水一篇。
前几天发了一版新的蚁剑JSP一句话的payload，这篇文章记录一下更新的细节。
1. 兼容高版本JDK
这个没啥好说的，就是base64解码的问题。在jdk9开始移除了sun.misc这个包，导致原有的
sun.misc.BASE64Decoder 没法继续使用，取而代之的是 java.util.Base64 这个类。
解决办法就是两个都试一下，看哪个能解码成功，核心代码如下
2. 兼容Tomcat内存马
这个问题可以掰扯一下。很多文章都提到了冰蝎或者蚁剑... | pdf |

反序列化脏数据
Java反序列化数据绕WAF之加⼤量脏数据
https://mp.weixin.qq.com/s/wvKfe4xxNXWEgtQE4PdTaQ
其实就是再最外层封装⼀层，只要该类有对象属性，⼀般来说在反序列化的时候都会试着调⽤该属性的
readObject去还原他。所以我们要找的class，第⼀需要实现java.io.Serializable接⼝，第⼆可以存储任
意对象。这么看来集合类型就⾮常符合我们的需求。

Beacon、Payload、Shellcode我傻傻分不清

有一段时间我发现好多安全从业者，也包括我，分不清楚C2工具中的一些名词，包括：Beacon、
Payload、Shellcode、Loader、Stager、Stagerless等。没办法都是舶来品，洋大人的文章中有时候也
是乱用的，更不要说国内的相关文章，导致大家对以上词汇的理解出现了分歧。然后就出现了相互交流
的时候鸡同鸭讲的情况，以下是我对这些词汇的理解，有分歧欢迎讨论。

Linux下echo计算哈希的坑
因为遇到好⼏次了，每次都忘记，搞得要怀疑⼈⽣⼏分钟，故简单记录下避免下次⼜⼊坑。
linux下常⽤的计算的哈希命令:
md5sum
sha256sum
但是这两个命令读取的是参数指定的⽂件名，或者是标准的输⼊。
那么如果我们想加密单个字符串的时候，⼀般会这样利⽤管道符来使⽤:
1. echo '123' |md5sum
2. echo '123'|sha256sum
得到的是:
123 -> md5 -> ba1f2511fc30423bdbb183fe33f3dd0f

Bypass AMSI的前世今生(3) - 脚本混淆和一行命令关闭AMSI
0x00 前言
本文的主要讲解[BA2-3]，也就是脚本混淆和一行命令关闭AMSI的原理，而不是具体的脚本混淆方法。
混淆方法其实就是对脚本语法的理解，然后加入各种额外字符或换一种表示方法。混淆姿势细致繁复，
并且在网上已有比较全面的脑图和总结文章，在此就没必要重复了，相关推荐资料会在文末贴出。本文
主要分为以下几个部分：
为什么脚本混淆能够过AMSI
一行命令关闭AMSI原理
[BA2]和[BA3]配合达到关闭AMSI的作用
学习建议，工具和相关资料推荐

0x01 前言
这种反制也只能钓 "涉世未深" 的攻击方，和一些脚本小子，算是蚁剑插件编写不规范造成的RCE
0x02 DHTMLX
在 \source\app.entry.js : 行28-57 可以看得见蚁剑在新版加载器中设置了替换函数，将对应的特殊
字符替换成实体编码！
它调用了dhtmlx框架，所以只要是UI渲染的页面都可能存在 XSS->RCE
我把目标盯向了其他插件
0x03 AS_Plug-in
从自带的插件实例的代码开始看: phpinfo
在 行14-22 当中，渲染UI框架的时候，调用了 unxss 可以知道这个地方不存在XSS漏洞
