Algonac water plant cellular modem cyberattack
Public report preview
Algonac officials said the city water filtration plant experienced a cyberattack targeting cellular modems used to communicate with remote PLCs, but the incident was contained without significant operational impacts. The timing, device class and UIS SCADA remediation closely match the late-July 2026 water-utility campaign, though no public authority has named Algonac as a confirmed campaign victim.
