A coordinated cyberattack targeted operational technology at more than 30 Minnesota community water systems on July 26 and 27, triggering a statewide cybersecurity response. Braham's water plant went offline and the city asked residents to minimize water use. Plymouth reported cellular communications problems at two water towers and several wastewater lift stations but kept operating manually. South St. Paul and Maple Plain also had automated controls affected, with Maple Plain declaring a local state of emergency. Minnesota IT Services said on July 28 it was not aware of any active requests for residents to change drinking-water use, and officials have not publicly identified the attacker, access method, or exploited vulnerability. MNIT is coordinating with CISA, the EPA and the FBI. Security firm Tenable says the timing and pattern are consistent with the Iran-linked CyberAv3ngers threat ecosystem, though the incident has not been officially attributed.
