S-Mimikatz源码调试
前期准备
mimikatz源码：地址
调试环境： vs2019
几点设置：
1. 因为官方项目没有debug方案，所以需要手动添加debug配置
2. 项目属性配置
程序入口
调试以 privilege::debug 为例。打开调试-> mimikatz 调试属性->配置属性->调试->命令参数
wmain()是 mimikatz`的入口函数。
命令分发
从上面的循环中获取到请求参数之后就进入到命令分发的 mimikatz_dispatchCommand() 函数。

0x01 前言
内存逃逸的第二部分主要是作者讲诉CS的Payload的一个完整执行流程，这个对理解CS植入体非常重
要，对后面做免杀、规避都起到很大作用。第一部分讲侦测手法、第二部分讲自身运行流程，真的是知
己知彼。这一部分作者先讲诉了Stager是什么？然后讲述一个分段加载Payload的完整执行流程，接着
就是不分段加载，最后作者讲了进程注入相关技术在CS中的应用。

关于分不分阶段，使用过CS的小伙伴应该都很清楚了，但是里面的具体细节，相信很多小伙伴也是一知

一次诡异的弱口令

项目开始没多久，一起的小姐妹说存在弱口令admin/admin，让我试试。然而在我尝试登录的时候，返
回消息为“密码错误，失败次数为1”。这没法登录，密码不对阿，还有账号锁定机制。
继续测试，发现登录页面验证码在使用后未作失效处理，正常操作，爆破一下。
burp的结果显示四五个账号存在弱口令，手动验证下，只有两个账号使用密码正常登录了，其他账号都
返回密码错误的消息。
弱口令登录不能复现，非常诡异，讲给客户估计会被客户加开发一起喷死，于是我就请教了一下我大

ASP/ASPX下的流量混淆
前言
今天谈一谈ASP/ASPX下的流量混淆姿势。
以执行 Response.Write("yzddmr6") 为例。
不带eval的普通编码方式
Unicode(asp/aspx)
利用iis解析unicode的特性，我们可以像sql的bypass一样来用unicode编码绕过。
mr6=Response.Write("yzddmr6")
蚁剑中aspx类型shell默认有unicode编码器，但是asp中没有，可以自己手动添加一份。
大小写(asp)
asp对于大小写不敏感，所以可以对payload中的字符进行大小写变换。
mr6=REsponSe.WriTe("yzddmr6")
要注意的是asp... | pdf |
CS的shellcode功能分析和代码重写实战

随着圈⼦⾥的新⼈越来越多，我准备从这⼀篇开始慢慢写⼀些与基础知识相关的⽂章，⽅便
⼀些对⼆进制安全知识了解不多的同学参考。虽然讲的还是基础知识，但是我也尽量写的实
⽤和有趣⼀点，防⽌与⽹上的⽂章出现同质化问题。
这篇要讲的问题是由上⼀篇⽂章 滥⽤具备RWX-S权限且有签名的dll进⾏⽆感知的shellcode
注⼊引出的，有同学问我为什么接收 metepreter 第⼆阶段的恶意代码需要那样写，本篇⽂
章就回答这个问题。
另外⾮常欢迎各位同学在圈⼦⾥提问，能为基础知识板块的编写提供更多素材

前言
很久很久以前freebuf发过一篇通过shiro反序列化拿下php网站的文章后，我大
受震撼，震撼到今天。
我今天花了一下午摸鱼做这个实验。实验非常简单，也就是我们如何让php网站
收到shiro探测的请求后让工具或脚本认为这是一个有shiro框架的网站？如何收
到密钥爆破检测请求的时候，通过请求的字段值来与后端密钥做匹配,更加逼真的
还原密钥爆破的场景，从而让脚本小子继续误入歧途？

⽬前的攻防场景，攻击成本的节约、周期短，成果要求⾼成了普遍要⾯对的问题，所以
对于基础设施的建设越来越重视，⼀键⾃动化的部署CS、Frp gen等⼯具的开发，节省了以
前略⻓的搭建配置时间，变相增加攻击有效时间；优化的Profile，⽐如修改⼀些默认标记
位、流量伪装、关闭stager等，成熟的OPSEC，⽐如杀软度测试、攻击⼿法检测测试、上传
⽂件清除流程等，减少了免杀难度系数，增加溯源难度的同时，也减少团队协作中执⾏了⼀
