## Cognito
For more information, access:
{% content-ref url="../aws-services/aws-cognito-enum/" %}
[aws-cognito-enum](../aws-services/aws-cognito-enum/)
{% endcontent-ref %}
### User persistence
Cognito is a service that allows to give roles to unauthenticated and authenticated users and to control a directory of users. Several different configurations can be altered to maintain some persistence, like:
* **Adding a User Pool** controlled by the user to an Identity Pool
* Give an **IAM role to an unauthenticated Identity Pool and allow Basic auth flow**
* Or to an **authenticated Identity Pool** if the attacker can login
* Or **improve the permissions** of the given roles
* **Create, verify & privesc** via attributes controlled users or new users in a **User Pool**
* **Allowing external Identity Providers** to login in a User Pool or in an Identity Pool
Check how to do these actions in
{% content-ref url="../aws-privilege-escalation/aws-cognito-privesc.md" %}
[aws-cognito-privesc.md](../aws-privilege-escalation/aws-cognito-privesc.md)
{% endcontent-ref %}
### `cognito-idp:SetRiskConfiguration`
An attacker with this privilege could modify the risk configuration to be able to login as a Cognito user **without having alarms being triggered**. [**Check out the cli**](https://docs.aws.amazon.com/cli/latest/reference/cognito-idp/set-risk-configuration.html) to check all the options:
{% code overflow="wrap" %}
```bash
aws cognito-idp set-risk-configuration --user-pool-id <pool-id> --compromised-credentials-risk-configuration EventFilter=SIGN_UP,Actions={EventAction=NO_ACTION}
```
{% endcode %}
