Hayward says several of its computer systems are down after a ransomware attack.
Investigators on Monday were assessing the damage from Sunday’s attack. It’s a precautionary step officials hope will prevent any more damage.
“I’m not going to get into details of systems that are affected,” city spokesperson Chuck Finnie said. “We are in an early phase mode of our IT department.”
Investigators don’t believe any personal information was compromised, according to Finnie.
The city is not disclosing how much the hackers are demanding.
Meanwhile, officials were looking into backup systems.
“There are mechanisms and systems through which systems are backed up, systems are maintained in clouds, but I can’t get into the details of our specific situation here,” Finnie said.
Although the city’s website remains down, Hayward’s 911, emergency dispatching, police, firefighter and emergency-medical services are still working.
Until the website is back online, the public can conduct business with the city by telephone, mail or in person.
City offices are open 8 a.m. to 5 p.m. Monday through Friday. The main Hayward City Hall phone number is 510-583-4000.
The Hayward Public Library’s hours are Monday-Wednesday 10 a.m. to 7 p.m., Thursday 11 a.m. to 6 p.m., and Friday and Saturday 10 a.m. to 5 p.m. Access to computers for public use will be unavailable until further notice.
