I get the impression that they did connect with yolo root access. >Although the ACIS application required access to only three databases within the Equifax environment to perform its business function, the ACIS application was not segmented off from other, unrelated databases. As a result, the attackers used the application credentials to gain access to 48 unrelated databases outside of the ACIS environment.
