est in the operations of water systems inside the U.S. dates back years. In 2016, the Justice Department charged a group of Iranian hackers in connection with a cyberattack targeting a small dam near New York City. Minnesota IT Services said that as of Thursday, there were no active requests from Minnesota communities for residents to modify usage of their drinking water. The state agency said most of the confirmed attacks involved technology that water systems use to remotely monitor and control equipment. It said that being impacted meant investigators confirmed there was malicious activity involving the system's technology and didn't mean every impacted community had their water service disrupted. For a few hours on Monday, the city of Braham asked residents to minimize water use as they tried to determine why the water plant was offline. The city of about 1,700 people, located about 70 miles (113 kilometers) north of Minneapolis, said in a news release that the water plant outage was due to a cyberattack, but it didn't cause any issue with water quality. The city said the attackers shut down the operating controls that shut down the well and water treatment plant. That left the city for a time only able to provide residents with the water held in the water tower. In Plymouth, a city of about 80,000 located outside of Minneapolis, officials said on social media that their water infrastructure communications had been restored by Tuesday afternoon following a cyberattack. During a Cabinet meeting on Friday at the Camp David presidential retreat in Maryland, President Donald Trump claimed without evidence that recent cyberattacks in Minnesota were the fault of the state, including Democratic Gov. Tim Walz. Waltz responded on social media, saying Trump knows exactly who is responsible for this attack, and knows that other states were hit too.
