Coordinated cyberattack disrupts U.S. water systems across several states

Hackers coordinated an attack on water facilities in multiple states, forcing boil-water notices and switching to manual operation as systems go offline. No drinking-water contamination has been reported, but the incident is being treated as one of the most serious cyberattacks on U.S. water infrastructure in years. Minnesota first flagged attacks on about 30 systems, with Wisconsin and others reporting related incidents; federal agencies (CISA, FBI, EPA) are scrambling to secure vulnerable PLCs and facilities. Attribution remains uncertain, though Iran is among suspected actors. Experts warn the water sector’s cybersecurity remains underfunded and under-defended against such intrusions.
