A initial systems audit was conducted on all systems from HMI through to control electronics to establish system baseline status for each telemetry control system.
Water Control system was performing poorly and database errors were suspected. System patches were not current and virus software version was out of date. The system crashed while checking performance issues. The Blaster virus was then discovered.


Impact was minimal due to the time of the failure.
