Description

On Monday the Cleveland Municipal Court announced via its Facebook page that it was closing due to a cybersecurity incident and that all internal systems and software platforms would be shut down until further notice. The same statement was reposted on Tuesday and Wednesday, marking the third consecutive day the court remained closed. The court said it had not yet confirmed the nature or scope of the incident. As a precautionary measure, the affected systems were taken offline while the court focused on securing and restoring services safely.

The closure disrupted the court’s normal operations, preventing public access to its services and leaving internal staff unable to use the shut down systems. Similar disruptions have been reported elsewhere, with municipal offices in Maryland’s Anne Arundel County shuttered on Monday after a cyberattack over the weekend and still taking precautionary measures after reopening on Tuesday. On January 11 the Qilin ransomware group claimed responsibility for an attack on the Connecticut city of West Haven that forced its IT systems to be shut down. In July of the previous year the city of Columbus, Ohio suffered a ransomware attack that exposed the personal information of more than 500,000 current and former residents.

The court’s response has consisted of keeping the affected systems offline, issuing daily updates via Facebook, and stating that it is working to secure and restore services safely. No further technical details have been provided by the court, and a spokesperson did not respond to requests for comment. The statement indicates that the systems will remain offline until the court gains a better understanding of the situation.
