CobaltStrike 插件的编写主要是使用agscript（Aggressor Script），这个CobaltStrike 3.0之后内置的脚
本语言。agscript是基于 Sleep 语言进行二次开发的。Sleep 是一种深受Perl启发的基于Java的脚本语言。
所以在开始编写 CobaltStrike 之前我们必须要了解 Sleep 语言的语法和agscript中内置的各种函数。

@yzddmr6
蚁剑最开始实现java加载shellcode是通过jna的⽅式，这个做法是来源于⼀个apt组织的⽅法
https://norfolkinfosec.com/jeshell-an-oceanlotus-apt32-backdoor/
但是不是很⽅便的⼀点是这个shellcode loader体积⼤于2m，超过了tomcat默认上传最⼤⻓度。所以之
前⼀直的做法都是先把编译好的jar上传到⽬标服务器，然后⽤URLClassLoader去加载⽂件。虽然⼀开

JspWebShell新姿势解读
写在前⾯
刚刚⽆意间发现我yzddmr6发了篇新⽂章，⾥⾯提到了⼀个jspwebshell的新姿势，但是没有
具体分析，那么这⾥我就接着来分析⼀波
⾸先代码长这样
正⽂
如果按照传统Java的javac的⽅式编译这样⼀定是会出错的，这⾥不贴图⾃⼰试试，⽽jsp不同
于普通的java程序，jsp是有⾃⼰的对类编译时的实现机制,其编译类的时候最终是
在 org.apache.jasper.compiler.JDTCompiler#generateClass ⽣成我们的class⽂件
(省略中途的很多步骤直捣黄龙，不然讲着也费劲)
这是调⽤栈，有兴趣可以深⼊分析

检测ldap协议以及获取相关字段的⼀种⽅式
JNDI注⼊常⽤rmi和ldap协议去打，本⽂主要讲述通过go语⾔检测ldap协议以及获取相关字段的⼀种⽅式
通过跟4ra1n师傅的⽂章的学习和与他本⼈的交流，他的检测思路是⽤go语⾔模拟回包，然后分析数据包，获取其中需要的路径字段。因为要确定⽬标是哪个payload⽣效，所以获取ldap/rmi请求的路
径是必要的。
