Columbus, Ohio confirmed that a ransomware attack in July 2024 compromised the personal data of 500,000 people. The attack, attributed to the foreign ransomware group Rhysida, resulted in 6.5 terabytes of stolen data and evidence being posted on the dark web. The incident reflects the growing vulnerability of local governments to cyber threats. Ohio officials have since offered financial and technical support, but experts note municipalities still trail the private sector in cybersecurity preparedness and response.
