Security News > 2023 > February > City of Oakland systems offline after ransomware attack
The City of Oakland was hit by a ransomware attack on Wednesday night that forced it to take all systems offline until the network is secured and affected services are brought back online.
The attack has not affected core services, with the City saying that 911 dispatch and fire and emergency resources are all working as expected.
The City's Information Technology Department is coordinating with law enforcement to investigate the attack and working on securing and restoring impacted services.
The ransomware group behind the attacks is currently unknown, and the City is yet to share any details regarding ransom demands or data theft from compromised systems.
As Emsisoft shared in January, ransomware attacks have impacted more than 200 hundred larger organizations in the U.S. public sector in 2022 across government, educational, and healthcare verticals.
Microsoft also revealed in January that it's tracking over 100 ransomware gangs that have deployed more than 50 unique ransomware families until the end of last year.
