## Background
* [Internet Information Services(IIS)](https://zhuanlan.zhihu.com/p/145430397)
    > IIS是縮寫，全稱Internet Information Services ( IIS,互聯網信息服務 ),是由微軟公司提供的基於運行Microsoft Windows的互聯網基本服務。
    >
    > IIS是指World Wide Web server服務，IIS是一種Web（網頁）服務組件，專業的說，IIS可以賦予一部主機電腦一組以上的IP地址，而且還可以有一個以上的域名作為Web網站。做過服務器配置的都應該知道IIS。制作好了網站怎麽才能讓別人瀏覽，就是通過網站服務器來實現的。IIS只是網站服務器的一種而已。
    > ### 簡單來說：
    >
    >Internet Information Service（IIS）是windows開設web網頁服務的組件，用來搭載網站運行程序的平台的。還能提供FTP，SMTP等服務。
    >
    ><font color="ff0000">在UNIX或Linux平台上，Apache就是網站服務器。
    >
    >而對於Windows NT/2000來說，IIS就是標準的網站服務器。</font>
    >
    >IIS是一種服務，是Windows 2000 Server系列的一個組件。不同於一般的應用程序，它就像驅動程序一樣是操作系統的一部分，具有在系統啟動時被同時啟動的服務功能。
    如果想知道如何在win10啟用IIS或是建置網站server，可以看這個影片[^IIS-on-windows]
* 一般權限(就像前面的lab那樣)
    * 取得網域使用者資訊
    * Scan Port
    * Check Group Policy Object
* 高權限好處
    * Dump Password or Hash
    * Turn off Defender
    * Check the other users' info
* 本地特出使用者
    * ==NT Authority\System==(本地端真正的最高權限使用者)
    * NT Authority\Network Service
    * NT Authority\Local Service
    * NT Authority\IUSR
* 提權方法
    * 利用弱點(通常是直接用Windows CVE直接打看看)，可參考[^win-exp-suggest-fei]
    * Hijack Token
    * Guess Password
        就像前面環境觀察中提到的一樣，可以從`Active Directory Users and Computers`的description中看看有沒有密碼的提示，或是查看`$ net user`變更密碼的時間是哪時候，然後考慮爆破
        * Local Admin比Domain Admin好拿
        * 通常是固定密碼
            * 所有主機都相同
            * 可能很多人知道
            * 弱密碼
            * 系統初始化包
        * Solution: 可以參考[本機系統管理員密碼解決方案(LAPS)](https://learn.microsoft.com/zh-tw/windows-server/identity/laps/laps-overview)
    * 管理服務
    * 錯誤配置

$ systeminfo.exe > systeminfo.txt # 這條指令是windows內建的指令，所以一定要在cmd中操作
$ python wes.py systeminfo.txt
