LAS VEGAS — A new program is seeking to assist water providers around the country as multiple states grapple with possible Iran-linked cyber intrusions against water infrastructure. The Water Watch Center provides direct cyber mitigation support to utilities serving fewer than 10,000 people, which represents most of the nation’s community water systems. More than 30 community water systems in Minnesota were targeted late last month, according to state officials. An initial group of five cybersecurity firms will help deliver services to water utilities as part of the initiative. Some U.S. officials believe Iran may be responsible, though there has been no definitive public confirmation.
