A cyber attack disrupted ticket sales for Estonia’s passenger train operator, Elron, on 20 September 2023, ERR reports. Ticket sales were disrupted at POS terminals, on trains, and online. Passengers could pay for tickets by cash on the train, however. The disruption was due to repeated DDoS attacks by supporters of Russia against the provider of Elron’s ticketing system, Ridango. The company managed to restore the system on 21 September 2023.
