A San Francisco Municipal Railroad (MUNI) train passing through the Mission Bay neighborhood. The San Francisco Municipal Transportation Agency was hit with malware that held its computer systems hostage on Friday and caused problems over the weekend as attackers reportedly sought a ransom to release their digital grip on the system. But fare machines inside the stations were lit up with “OUT OF SERVICE” messages over the weekend, according to the San Francisco Examiner, which was among the first outlets to report on the incident. The email described the attack as a “proof of concept” and said SFMTA systems were poorly secured. The FBI advised businesses to regularly back up their data so it can be restored if they’re attacked.
