On Saturday evening, reports from San Francisco outlined a malware attack causing problems for SFMTA. MUNI riders were given free access after station payment machines and schedule monitors started displaying a “You Hacked” message, warning that all data was encrypted.
Local media and other statements from SFMTA employees say the attack started just prior to the Thanksgiving holiday. CBS 5, a San Francisco affiliate, first broke the news on Saturday, reporting the problems had started a few days earlier.
