Goal

Detect when a user successfully requests to view a CosmoDB access key with the Azure API. An attacker with the appropriate privileges can view an access key and use it to access and manage the CosmoDB database.

Strategy

Monitor Azure CosmoDB logs where @evt.name is "MICROSOFT.DOCUMENTDB/DATABASEACCOUNTS/LISTKEYS/ACTION\" and @evt.outcome is Success.

Triage and response

  1. Verify that the user ({{@usr.name}}) should be viewing the access key for the following CosmoDB database: ({{@resourceId}}).
  2. If the activity is not expected, investigate the activity around the CosmoDB Database ({{@resourceId}}).
