All incidents

Between July 26 and 27, a coordinated cyberattack disrupted water and wastewater operations across more than 30 Minnesota communities, according to Tenable's summary. Some automated controls were affected and Maple Plain declared a local state of emergency. In Plymouth, only equipment connected over cellular links was hit and manual operation kept water flowing. Separately, cyber activity caused a pressure drop at the Clayton County Water Authority in Georgia, prompting a boil-water advisory for 300,000 customers, with service restored within hours. A federal investigation is pending and attribution is not confirmed, although the timing matches the Iran-linked controller activity in CISA's advisory. SecurityWeek reports that the FBI and EPA later said water systems in at least seven states were targeted.
