The IT person at a water utility, unhappy about not receiving a pay raise, reprogrammed the SCADA system to shut off the high-lift pumps and prevent alarms from notifying operators of a pump failure. He also blocked others from accessing the SCADA system. As a wildfire broke out near the city, this cyberattack threatened to disrupt the water supply. New countermeasures should have included access controls and monitoring to prevent unauthorized changes to the SCADA system, as well as backup systems and emergency procedures to maintain operations during an attack or failure.
