Security News > 2021 > May > City of Tulsa's online services disrupted in ransomware incident
The City of Tulsa, Oklahoma, has suffered a ransomware attack that forced the City to shut down its systems to prevent the further spread of the malware.
Tulsa is the second-largest city in Oklahoma, with a population of approximately 400,000 people.
Over the weekend, threat actors deployed a ransomware attack on the City of Tulsa's network that led to the City shutting down all of its systems and disrupting online services.
The shutdown of City systems is preventing residents from accessing online bill payment systems, utility billing, and services through email.
Websites for the City of Tulsa, the Tulsa City Council, Tulsa Police, and the Tulsa 311 websites are also down for maintenance.
"The City of Tulsa is experiencing technical difficulties on many outward facing programs that help serve the citizens of Tulsa due to a ransomware attack. No customer information has been comprised, but residents will not be able to access City websites and there will be delays in network services," says a post to the Tulsa Police Department's Facebook page.
