The Record reports that Cleveland shut down its city hall on Monday in response to a cyberattack.
In a statement to Recorded Future News, a city spokesperson would not say what systems were shut down due to the incident but confirmed that police, fire and emergency medical services are still functioning, as is the 911 dispatch center. Systems controlling the local ports and public utilities are also not affected.
“While City systems remain offline, all daytime 311 calls will be handled by after-hours operators,” the spokesperson explained. “All internal systems and software platforms will be shut down until further notice.”
Cleveland has yet to disclose whether the attack on the city was a ransomware attack or some other kind of attack. No ransomware group has claimed responsibility for the attack, but even if it is a ransomware attack, the attackers would not necessarily announce that so soon if they are trying to get their target to negotiate with them.
