This KQL detection is designed for use in Microsoft Defender for Endpoint Advanced Hunting or Microsoft Sentinel, depending on table availability.
It focuses on identifying two common persistence techniques used by threat actors:
COM hijacking via user-specific registry hives (InprocServer32 and LocalServer32), particularly when leveraged by .NET or PowerShell-based malware; and uncommon registry-based persistence through suspicious keys such as DelegateExecute, TreatAs, and ScriptletURL.
The KQL focusses on user-specific registry hives as they don't require elevated privileges to modify and is why we also ignore "nt authority" activity as this detection is focused on low hanging fruit that would be easily accessible to a threat actor initially for persistence without privilege escalation.

KQL Query from file: Potential MFASweep (tool) activity has been detected.
Detects when a Global Administrator elevates access to all subscriptions and management groups in a tenant. When a Global Administrator elevates access they are assigned the User Access Administrator role at root scope. This Sentinel analytics rule monitors who has elevated access in your tenant so that admins can take appropriate action.
This detection identifies when Microsoft Copilot Studio agents are created in your organization's tenant. This activity is significant as the default behavior in Copilot agent creation is to configure a new service principal with cloud app administrator role.
Copilot agents can be found in the Microsoft Admin Portal https://admin.microsoft.com/Adminportal/Home#/copilot/agents

This KQL detection rule identifies suspicious login attempts in the SigninLogs dataset where a sign-in was blocked because it originated from an IP address flagged for malicious activity.
The rule specifically focuses on cases where valid credentials or token claims were used during the authentication process.
