A DoS attack on an automotive vehicle's CAN network can overload the system, preventing the delivery of CAN messages. In such scenarios, different ECUs respond variably. For instance, in a Ford vehicle, the overload causes the PSCM ECU to shut down, disabling steering assistance. Consequently, the steering wheel becomes rigid, limiting turns to approximately 45%, thereby preventing sharp maneuvers.

Adversaries can exploit a security vulnerability in the Polish train system by sending simple "radio-stop" commands via radio frequency, triggering the trains emergency stop function. The radio system lacks encryption or authentication, allowing anyone with radio equipment to execute the command.
