Foster City Hit by Ransomware Attack, Disrupting Public Services Foster City, California, has suspended most public services following a ransomware attack detected on its networks early Thursday morning. The city confirmed the breach in a news release, stating that non-emergency operations were temporarily paused while an investigation assesses the full scope of the incident. Emergency services, including 911 and police dispatch, remain operational and unaffected. However, the city acknowledged that public information may have been accessed during the breach. Limited details are currently available, but officials are working to declare a state of emergency to facilitate external support in restoring systems. City Manager Stefan Chatwin emphasized that public safety remains the top priority, with city employees and cybersecurity experts actively working to secure systems and prevent further disruptions. The incident highlights the growing threat of ransomware targeting municipal infrastructure, with recovery efforts ongoing.

Suisun City Declares State of Emergency Following Cyberattack on Critical Services On August 4, 2025, Suisun City, located in Solano County, California, suffered a cyberattack that disrupted key municipal operations, including public safety systems. The incident began at approximately 5:45 a.m. when "malicious software" infiltrated the city’s IT infrastructure, prompting an immediate shutdown of its entire network to preserve evidence for a federal investigation. The attack impacted critical services such as 911 routing, police and fire dispatch, and city records management. While emergency call handling was rerouted to Solano County’s dispatch center, some software-dependent functions became temporarily unavailable. City officials confirmed there was no direct threat to public safety, though residents may experience delays in non-emergency services like bill payments and permit processing. Suisun City declared a state of emergency on August 5, enabling faster access to emergency resources and potential cost recovery. The city is collaborating with the FBI, the Department of Homeland Security, and the California Office of Emergency Services to investigate the breach and restore systems. No timeline has been provided for full recovery. The attack follows a recent trend of cyber incidents targeting local governments in the region. Earlier in 2025, Foster City and Pittsburg faced similar disruptions, with Foster City declaring a state of emergency after a March ransomware attack and Pittsburg losing nearly $1 million in a February phishing scam. Cybersecurity experts note that municipalities are frequent targets due to perceived vulnerabilities, often with ransom demands as the primary motive.
