After discovering a cyberattack on August 24, 2025, the Nevada state government temporarily closed its offices and suspended some websites and phone services. Emergency services remained in operation, and although the state initially said there was no evidence of a personal data breach, it later confirmed a ransomware attack and the theft of state data.
