Since the exploit would specifically occur using a local account on the Domain Controller, it stands to reason that detecting a modified user object, modified by a local system account, would be evidence of the exploit. The split removes the '$', creating a new field, deriving the local_system name via the original user field [ie. user='NameOfDC$' would become local_system='NameofDC']")` | search host=local_system `comment("A search to only find instances of these events when the host (DC) is the same as the extracted local_system account name performing the action")` | table _time EventCode dest host ComputerName src_user Account_Name local_system user Security_ID member_id src_nt_domain dest_nt_domain |
You can also modify this search to only look at your Active Directory DCs. If you have common naming schemas, you can use that as well. Please see the report linked to get more info about the CVE itself.

REST API: Table all Splunk User Email Addresses
The following simple Splunk query will put all Splunk User accounts with an email address into a panel for copy and paste purposes (such as copying all email addresses to send in an email). I’ve added a semi colon delimiter in order to literally be copy and paste into an application such as Microsoft Outlook. […]
Bucket Status Dashboard

Detect Dying Sourcetypes
This alert is used for looking at a prior dataset of indexes and sourcetypes reporting over time, and then involves pairing to a closer, temporal dataset. Appending the results allows you to view sourcetypes that have stopped reporting, but existed in the prior period.

Triggered Alert Analytics
Primary Dashboards Contains alert analytics for both triggered alerts and saved searches. Please replace $name$ with the saved search naming convention you utilize (ie. 0001 – AlertName). You will need an outputlookup to generate the bottom two tables; it will be based on the query that generates the second table in the dashboard.

Groundspeed Violation/Improbable Access
Oftentimes we are required to determine impossible or improbably access events. Typically, this is a relatively simple thing to do in a modern SIEM, however Splunk, without ESS, does not have a “great” way to handle this type of temporal correlation aside from appends or joins back to the original data. I constructed the following […]
