AI Summary

A coordinated cyberattack struck more than 30 Minnesota community water systems over July 26‑27, according to Minnesota IT Services. The attack targeted the same operational‑technology weakness that links many small utilities, marking the first distributed campaign against dozens of such facilities. While the utilities reported that drinking water remained safe and disruptions were limited, security researchers view the incident as part of a broader, months‑long campaign aimed at U.S. water infrastructure amid heightened tensions with Iran. The event is described by Nozomi Networks’ field CISO Markus Mueller as a first‑of‑its‑kind distributed attack aimed at disruption rather than financial gain.
