"Authorities in Denmark are urgently studying how to close an apparent security loophole in hundreds of Chinese-made electric buses that enables them to be remotely deactivated. The investigation comes after transport authorities in Norway, where the Yutong buses are also in service, found that the Chinese supplier had remote access for software updates and diagnostics to the vehicles' control systems which could be exploited to affect buses while in transit."
"Amid concerns over potential security risks, the Norwegian public transport authority Ruter decided to test two electric buses in an isolated environment. Bernt Reitan Jenssen, Ruter's chief executive, said: The testing revealed risks that we are now taking measures against. National and local authorities have been informed and must assist with additional measures at a national level. Their investigations found that remote deactivation could be prevented by removing the buses' sim cards, but they have not done this because it would also disconnect the bus from other systems."

Movia operates 469 Chinese electric buses and plans stricter security requirements for future procurements. Officials warned that internet-connected subsystems increase vulnerability.
