Cyberattacks on U.S. water supply systems that officials believe may be linked to Iran-backed hackers have been reported in at least 12 states, CBS News reported, citing sources familiar with the matter, writes UNN.

These states include Michigan, Minnesota, Georgia, New Jersey, and South Dakota. In Minnesota alone, more than 30 public water systems were affected.
In Georgia, the Clayton County Water Authority, which serves 300,000 customers in the Atlanta area, said that cyber activity last month caused water pressure to drop and forced the agency to issue a boil-water advisory. However, service was restored within several hours.
Some utilities lost critical remote-control capabilities, forcing operators to switch to manual mode. In several cases, hackers gained remote access to pumps, valves, and water pressure.
So far, according to officials, the cyberattacks have not affected drinking water, which remains safe.
