自动化生成器
前面核心的内容跑通了，后面自动化生成就是理所当然的，这方面没什么困难的，就是注意一下加一些
对抗的东西，比如生成的源码里面的字符串全部加密，用于加解密shellcode的key全部随机化生成。将
源码一起打包，并告诉编译方式，这样即使生成的dll被杀了也没关系，自己改改又可以继续了。
一些核心功能：
收集一些白加黑文件，制作成模板
解析白文件pe，将shellcode写入证书目录
根据模板来生成劫持dll
自动调用go命令进行编译
自动打包成zip
里面最麻烦的就是自动编译，因为服务器是linux，而要生成windows的程序，并且在go里面使用了
cgo，不可避免的，要使用交叉编译器了。

众测困住你的那些问题
jkgh006 | 众测资深玩家，多家众测平台TOP白帽
前 言
安全趋势的发展，现在已经变成三大阵容，一个是代表过去的传统漏洞平台，第二个是以乙方为
首的众测平台，以及以甲方主导的SRC平台 ， 传统的漏洞平台慢慢的淡出视野，现在最火的莫过于
SRC和众测，所有的类型终将归为一种方法，所以对于其中众测也是有一套方法论，怎么分析，怎
么去绕，怎么去获取证据，等等都是有章可循，我们重点关注众测困住你的那些问题。

在域内，有很多种⼿法可以获取域控权限，包括不限于利⽤溢出类的漏洞如ms17-010、抓取域管密码，当然也有

没有发过⽂章，主管都准备踢我出球了，所以特地⽔⼀篇⽂章。
找了找星球还没有k8s之类的⽂章，于是⽔⽂章思想更重。
之前从来没怎么接触过k8s，但是随着云原⽣以及微服务架构的兴起，云原⽣必定是攻防重点，很多⾯试

ASP.NET下的内存⻢(⼀)：filter内存⻢
前⾔
过程
总结
@yzddmr6
asp.net下的内存⻢研究⽂章⽐较少，⽬前提到过的包括虚拟路径内存⻢以及HttpListener内存⻢。周末
研究了⼀下其他类型的内存⻢，发现.net可以利⽤的地⽅要多得多。所以准备写个系列⽂章，讲⼀讲
asp.net下的内存⻢。
⽂章仅作研究性质，不保证任何实战效果，请勿⽤于⾮法⽤途。
java下有filter，servlet等拦截器，asp.net mvc也有同样类似的机制。
在rider中新建⼀个asp.net web项⽬，默认就会起⼀个asp.net mvc的项⽬。
