Largest US Water Utility Suffers Significant Cyberattack, says Operations Not Impacted.
There was a cyberattack Thursday at American Water. The attack involved unauthorized access to American Water's computer networks and systems. American Water responded to the attack by shutting down some of its systems to prevent further risk to its systems. The precise type of attack was not initially disclosed by American Water, though some early speculation claims that it was a ransomware attack. The company took its customer portal called MyWater offline.
“We currently believe that none of the water or wastewater facilities or operations have been negatively impacted by this incident,” the company said.
Impact of the attack: systems shutdown, customer service disruption, billing suspension, potential data breach, reputational damage.
American Water said the investigation is ongoing and will take time to complete.
