Bristol Airport was faced with a blackout of flight information screens for two days over the weekend due to a ransomware attack. The attack affected several computers over the network, including its in-house display screens that provided information about flight arrival and departures. The airport staff had to rely on whiteboards to announce check-in, arrival and departure details. The ransomware was not paid in this case and the airport staff took down their systems while they serviced affected computers.
