The City of Oakland initially informed residents of the ransomware attack on Feb. 10, nine days after the attack began. Several non-emergency systems were impacted afterwards including city phone systems, wireless internet at libraries, and the parking citation center. Most of these systems were back up by Feb. 28.
Cybersecurity analyst and security researcher Dominic Alvieri tells KRON4 he saw the post from PLAY threat group. He says employee IDs, passports and other documents were shared in the leak.
