Ransomware attack disrupts Nevada state government services
After discovering a cyber-attack on 24 August 2025, the Nevada state government temporarily closed its offices and suspended some websites and telephone 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. The attack was traced to a state employee installing a system administration tool containing malware, and the state spent $1.5 million on its response without paying a ransom.
