The San Francisco Municipal Railway (MUNI) has fallen victim to a ransomware attack. The entire ticketing system was taken offline on Friday evening, and stayed down all day Saturday, with the message: "You Hacked, ALL Data Encrypted. Contact For Key(
cryptom27@yandex.com)ID:681” appearing on MUNI agents’ computer screens.
With no way to collect fares over the weekend, ticket staff was sent home and the turnstiles were opened. Signs were taped to ticket machines all day Saturday indicating the rides would be free.
