The Minnesota Municipal Water Systems Cyberattack

First aired Latest aired

Gone quiet since

Where it stands

More than 30 Minnesota community water systems have been affected, and the FBI found altered controller project files; reports say the wider U.S. campaign has spread to at least 12 states. Some Minnesota communities switched to manual operations or conservation measures, but the reports do not establish that affected systems have been restored or that the investigation into responsibility and impacts is complete.
