Azure Resource Group Admin Privilege Granting

Triggers

• Assignment of a highly permissive role to an entity at a Resource Group level.

Possible Root Causes

• Unauthorized Privilege Escalation: An attacker is modifying permissions to gain additional or persistent access to the environment.
• Administrative Change: An administrator has been granted a highly permissive role to enable full access to the environment.

Business Impact

• Lateral movement may indicate that an adversary has established a foothold in the environment and is progressing towards their objective, increasing the risk of material impact.

Steps to Verify

• Investigate the Principal: Review the identity that performed the role assignment for other signs of malicious activity.
• Validate Privilege Justification: Assess whether the entity should have the assigned level of privilege based on their normal duties.
• If Malicious Actions or High-Risk Configurations Are Suspected:
  • Revert any unauthorized configuration changes.
  • Disable credentials associated with this alert to prevent further misuse.
  • Conduct a comprehensive investigation to determine the initial compromise and scope of impacted resources.
