只有管理员权限才能加载dll提权到system，理论上不应该是user -> system吗？

MySQL高交互反制蜜罐实践
0x00 背景
MySQL客户端任意文件读取“漏洞”由来已久，近年来由于护网的兴起，基于该漏洞的MySQL反制蜜罐
也频繁出现。然而很多商业蜜罐都是基于一些开源的验证性脚本进行开发（见参考链接），以这个完成
度来钓红队简直是在侮辱红队的智商。那么MySQL反制蜜罐从PoC到工程化实践中要解决哪些坑呢？咱
们今天来一一介绍。
0x01 PoC的局限
MySQL读文件漏洞的原理网上有一大把分析文章，这里就不再赘述了。先来简单看一个典型的PoC
的执行流程，如下图。客户端登录后向服务端发送查询请求之后，服务端返回了读文件的响应，客户端
乖乖就范，把文件发给了服务端。此时一般情况下服务端应该返回一... | pdf |

众所周知，Cobalt Strike的一些功能模块都是用spawn的方法实现，其原理就是启动一个进程，然后对该
进程进行功能模块dll反射注入，默认profile下是启动rundll32.exe这个进程，这种行为在数字的核晶模式
下是会被拦截的。前两天刚好在吐司看到一篇文章有讲到，修改Cobalt Strike的源码将spawn的方式修改
为inject的方法是可以bypass数字核晶的，因为将Cobalt Strike内置的功能模块dll注入到当前进程就没有
新启进程的行为。本文结合上述文章并在@wonderkun师傅的帮助下得到了一个更好的修改方案。

⾃动化通⽤DLL劫持
之前写过⼀篇
使⽤⽩加⿊的⽅式⽣成"冲锋⻢"，使⽤到部分 dll 劫持的技术。但是它的场景是劫持后阻断正常⽩⽂件的运⾏，程序的控制权交到“⿊⽂

这篇⽂章是对通⽤ DLL 劫持的研究，期望能制作⼀个通⽤的 DLL，劫持程序原有的 dll 但保留原 dll 的功能，同时执⾏⾃⼰的代码，这个 dll
最好能⾃动⽣成(不要⼿动编译)，主要⽤于维权场景。

这里应该也不用我揭晓答案了，拿去运行一下应该都一目了然了，上面提出的那2个代码均来自 php

判断错误的人想法可能如下：
