# Delete or rename shell history

### Event Information

#### Meaning

* The Delete or rename shell history event in a Kubernetes cluster refers to an action where a user or process attempts to delete or rename the shell history file.
* This event can indicate potential attempts to cover up unauthorized activities or hide sensitive information by removing or modifying the shell history.
* To investigate this event, you can use the `kubectl exec` command to access the container where the event occurred and check for any suspicious activities or modifications to the shell history file. For example: `kubectl exec -it <pod-name> -- /bin/bash`.

#### Remediation

To remediate the event "Delete or rename shell history using python Kubernetes API", you can follow these steps:

1. Identify the affected Pod:
   * Use the `kubectl get pods` command to list all the Pods in the cluster.
   * Look for the Pod that triggered the event based on the Pod name or other relevant information.

2. Investigate the Container :
   * Access the container to review recent activities:
     ```
     kubectl exec -it <pod-name> -n <namespace> -- /bin/bash
     ```
   * Check the shell history file (\~/.bash\_history or equivalent) for any suspicious entries:
     ```
     cat ~/.bash_history
     ```
   * Look for any attempts to delete or rename the history file:
     ```
     ls -la ~/
     ```
   * Look at the container logs for any indication of commands executed around the time of the event:
     ```
     kubectl logs <pod-name> -n <namespace>
     ```

3. Update Security Policies :
   * Consider limiting shell access to containers by setting appropriate security contexts and using container security best practices.

4. Remove or Rename the History File (if necessary):
   * If you need to remove or rename the history file as part of your cleanup, do so carefully:
     ```
     kubectl exec <pod-name> -n <namespace> -- rm ~/.bash_history
     ```
     or
     ```
     kubectl exec <pod-name> -n <namespace> -- mv ~/.bash_history ~/.bash_history_old
     ```

Note: Make sure you have the necessary permissions to execute these commands on the cluster.
