sap impossible travel
YARA-L
Identifies two successful logons for the same User ID from two different geographic locations in a timeframe that is physically impossible to travel between, indicating credential sharing or theft.
Identifies when an admission controller is executed in Azure Kubernetes.
A Kubernetes Admission controller intercepts, and possibly modifies, requests to the Kubernetes API server.
The behavior of this admission controller is determined by an admission webhook (MutatingAdmissionWebhook or ValidatingAdmissionWebhook) that the user deploys in the cluster.
An adversary can use such webhooks as the MutatingAdmissionWebhook for obtaining persistence in the cluster.
For example, attackers can intercept and modify the pod creation operations in the cluster and add their malicious container to every created pod.
An adversary can use the webhook ValidatingAdmissionWebhook, which could be used to obtain access credentials.
An adversary could use the webhook to intercept the requests to the API server, record secrets, and other sensitive information.

Detects when an account was created and deleted in a short period of time.
Detects when PIM alerts are set to disabled.
Identifies that users were active from an IP address that has been identified as an anonymous proxy IP address.
Atypical Travel
Sigma
Identifies two sign-ins originating from geographically distant locations, where at least one of the locations may also be atypical for the user, given past behavior.
Impossible Travel
Sigma
Identifies user activities originating from geographically distant locations within a time period shorter than the time it takes to travel from the first location to the second.
New Country
Sigma
Detects sign-ins from new countries. The detection considers past activity locations to determine new and infrequent locations.
Indicates anomalous behavior based on suspicious sign-in activity across multiple tenants from different countries in the same browser
Indicates user activity that is unusual for the user or consistent with known attack patterns.
Identifies when an account hasn't signed in during the past n number of days.
Invalid PIM License
Sigma
Identifies when an organization doesn't have the proper license for PIM and is out of compliance.
Identifies when a privilege role assignment has taken place outside of PIM and may indicate an attack.
Identifies when the same privilege role has multiple activations by the same user.
Identifies when a privilege role can be activated without performing mfa.
Identifies when a user has been assigned a privilege role and are not using that role.
Detects risky authentication from a non AD registered device without MFA being required.
Device code flow is an OAuth 2.0 protocol flow specifically for input constrained devices and is not used in all environments.
If this type of flow is seen in the environment and not being used in an input constrained device scenario, further investigation is warranted.
This can be a misconfigured application or potentially something malicious.

Detects when there is a interruption in the authentication process.
Detects a successful login to the Microsoft Intune Company Portal which could allow bypassing Conditional Access Policies and InTune device trust using a tool like TokenSmith.
Detects when a Microsoft Cloud App Security reported when a user signs into your sanctioned apps from a risky IP address.
