This rule identifies Windows Server devices, specifically potential Domain Controllers, that are flagged as vulnerable to CVE-2026-27912 (ResetNightmare) and CVE-2026-25177 (KerberLoss). It checks for the absence of the March/April 2026 cumulative updates that address critical Kerberos Change Password and Service Principal Name (SPN) logic flaws.
Added credential from country X and Signed-In from country Y in a pecific time window:
This query tries to find all applications that credentials were added to them from country X while the application's identity Signed-In from country Y in a specific time window.

This query was originally published in the threat analytics report, Solorigate supply chain attack. Please note that these attacks are currently known as the Nobelium campaign.
Microsoft detects the 2020 SolarWinds supply chain attack implant and its other components as part of a campaign by the Nobelium activity group. Nobelium is the threat actor behind the attack against SolarWinds, which was previously referred to as Solorigate.
Nobelium silently added malicious code to legitimate software updates for Orion, which is IT monitoring software provided by SolarWinds. In this way, malicious dynamic link libraries (DLLs) were distributed to SolarWinds customers.
The following query retrieves an inventory of SolarWinds Orion software use in your organization, organized by product name and ordered by how many devices the software is installed on.
More Nobelium-related queries can be found listed under the See also section of this document.

Detects various Windows Update errors, including failures to connect to the update service, installation failures, uninstallation failures, revert failures, and commit failures. Monitoring these events is crucial to ensure that critical security updates are being successfully applied to systems. Persistent errors could indicate issues with network connectivity, compromised update services, or attempts to prevent system patching, which could leave systems vulnerable to known exploits.
