Cyberattack on Switzerland's March District disrupts administration and secondary-school teaching

Swiss cybersecurity authorities alerted the March District to an intrusion on December 9, 2023. On December 12, district officials shut down information systems to contain the threat, interrupting telephones, email, internet connectivity and several administrative services. The district's secondary schools lost access to digital classroom infrastructure, forcing approximately 1200 students to continue lessons without normal electronic teaching tools. Scheduled court hearings proceeded, although judicial and other administrative offices experienced communication and technology limitations. District administration systems recovered progressively while the schools remained on restricted digital operations. The original candidate's November 23 date is incorrect; the documented incident occurred in December.
