> In one train set, researchers discovered a device signed as a “UDP<->CAN converter”, presumably enabling remote communication with the train. Removing it did not make anything stop working. Analysis showed that the on-board computer was sending lock status information to this device, and that the device itself was connected to a GSM modem.

Takže prakticky backdoor. Jde přes CAN bus ovládat brzdy? To bych pak viděl na obecné ohrožení.
