Overview
- Malicious software began affecting Suisun City’s computer systems at about 5:45 a.m. Friday, prompting officials to shut down the entire network and activate the Emergency Operations Center.
- City dispatchers are routing 911 calls through the Solano County dispatch center and police and fire crews are continuing in-person responses, with officials saying there is no imminent public threat.
- The Suisun City Council unanimously declared a state of emergency Saturday to speed access to outside support and to recover costs tied to the cybersecurity incident.
- Federal and state partners including the FBI, Department of Homeland Security and California Office of Emergency Services are involved in containment and forensics, but investigators have not yet determined how the malware entered systems or who is responsible.
- Many online city services and internal operations remain offline, a situation that could prolong paperwork delays and raise municipal costs as cities increasingly face costly cyberattacks on critical public-safety and records systems.
