American Water , the largest water utility in the U.S., disclosed that it had been hit by a cyberattack.
Hacks targeting U.S. water infrastructure, in particular, have been increasing, with some of the attacks linked to geopolitical rivals of the U.S., including Iran, Russia and China.
"All drinking water and wastewater systems are at risk — large and small, urban and rural," an EPA spokesman recently told CNBC.
American Water provides drinking water and wastewater services to more than 14 million people with regulated operations in 14 states and on 18 military installations.
It said turning off customer systems was intended to protect data, though it added that it is too soon to know whether any customer information is at risk.
