BAKERSFIELD, Calif. (KGET) — The city of Shafter says it is working with federal law enforcement after its computer system was compromised by a ransomware attack, locking city staff out of the system.

Shafter officials say they don’t believe any personal information has been breached. They say they are working on getting a few services back up and running and working with federal law enforcement to determine the source of the attack.

Residents who need access to the city finance department can get help through the alley window and City Services will be open for manual transactions, the city said.
