AD FS Remote Auth Sync Connection

Identifies suspicious AD FS authentication by correlating Security events from "AD FS Auditing" with Windows Filtering Platform (WFP) events for incoming port 80 traffic. This may indicate a threat actor abusing AD FS replication services to obtain configuration settings and sensitive information such as AD FS certificates. Enable AD FS auditing on the AD FS server before using this query. References: https://learn.microsoft.

SSH - Potential Brute Force

Identifies an IP address that had 15 failed attempts to sign in via SSH in a 4 hour block during a 24 hour time period. Please note that entity mapping for arrays is not supported, so when there is a single value in an array, we will pull that value from the array as a single string to populate the entity to support entity mapping features within Sentinel. Additionally, if the array is multivalued, we will input a string to indicate this with a unique hash so that matching will not occur.

Failed logon attempts in authpriv

Identifies failed logon attempts from unknown users in Syslog authpriv logs. The unknown user means the account that tried to log in isn't provisioned on the machine. A few hits could indicate someone attempting to access a machine they aren't authorized to access. If there are many of hits, especially from outside your network, it could indicate a brute force attack. Default threshold for logon attempts is 15.

Subscription moved to another tenant

This detection uses AzureActivity logs (Security category) to identify when a subscription is moved to another tenant. A threat actor may move a subscription into their own tenant to circumvent local resource deployment and logging policies. Once moved, threat actors may deploy resources and perform malicious activities such as crypto mining. This is a technique known as "subscription hijacking".

Pathlock TDnR - User-Role Assignment Changes

Description

Detects changes to user-to-role assignments in SAP (SU01 roles tab), forwarded by Pathlock Threat Detection and Response. Unauthorized role assignments are the primary mechanism for granting and revoking SAP access, and unexpected changes may indicate privilege escalation, account backdooring, or unauthorized access provisioning.
