The Cape May Water and Sewer Department and the Woodbine Water Department were both affected by the incidents, officials said Thursday. Hackers gained access to monitoring systems but did not breach computers that control water operations. NBC News has reported that Iran is believed to be behind attacks affecting utilities in seven states, including New Jersey. The proposal comes as federal officials continue to warn that water systems, power providers and other utilities remain attractive targets for foreign adversaries seeking to disrupt critical infrastructure.
