Goal
Detect references to NTDS.dit file in command line
Strategy
All data in Active Directory is stored within the file ntds.dit. Typically located on the domain controller, there are a variety of methods available for a threat actor to extract this file, with the most common being utilization of the ntdsutil command or extracting it from a shadow copy or backup of the domain controller. This detection looks to identify when process arguments are referencing the ntds.dit file, as it could be evidence of a threat actor attempting to exfiltrate the file.
Triage and response
- Identify what is being executed and if it is actually accessing the ntds.dit file.
- If it’s not authorized, isolate the host from the network.
- Follow your organization’s internal processes for investigating and remediating compromised systems.
Requires Agent version 7.50.0 or greater.
This rule is a part of the beta for detections on Windows! If you would like to try the new Windows agent, create a support ticket and indicate that you wish to join the Cloud Security Management - Windows beta.
