Malware Turns Off Traffic Lights in Liechtenstein
On Saturday morning, February 3, 2024, there was a total failure of the traffic lights in the Gnalp-Steg tunnel in Liechtenstein. According to initial assessments by the manufacturer, the failure was caused by malware. How this got onto the traffic lights' server is currently the subject of investigations.
"Traffic control was carried out manually on Saturdays and Sundays by employees of the Office for Civil Engineering and Geoinformation. This meant that traffic could be managed without problems at the weekend. On Monday, February 5, 2024, a construction site traffic light was set up to temporarily regulate traffic in the tunnel. During this phase, short waiting times are to be expected in some cases. The responsible authority and the manufacturer of the traffic lights are working on restarting the traffic lights. The restart should take place before the weekend.}
