These searches look for activity consistent with attackers attempting to disable different security mechanisms.
Endpoint data that records process activity from your hosts, and logs with both the process name and command line from your endpoints. Use this data to populate the Processes node of the Endpoint data model in the Common Information Model (CIM). For information on installing and using the CIM, see the Common Information Model documentation.
How to use Splunk software for this use case
To deploy this use case, make sure that you have the Splunk ES Content Updates installed on your Splunk Enterprise Security deployment. This extensive content library empowers you to deploy out-of-the-box security detections and analytic stories to enhance your investigations and improve your security posture. If you do not have Splunk Enterprise Security, these detections will still give you an idea of what you can accomplish with SPL in the Splunk platform or with the free app, Splunk Security Essentials.
Some of the detections that can help you with this use case include:
- Attempt to add certificate to untrusted store
- Attempt to stop security service
- Processes launching netsh
- Sc exe manipulating Windows services
- Suspicious reg exe process
- Unload Sysmon filter driver
- Windows common abused CMD shell risk behavior
