TL;DR
In the world of embedded systems and hardware, lessons can be learned from unexpected places. The story of the defunct Estonian scooter company Äike highlights the importance of security in IoT devices and the implications of poor design decisions when manufacturers go out of business. With the app and cloud services for these scooters no longer functioning, a developer took it upon themselves to reverse engineer the scooter's system, leading to a significant discovery that underscores the need for better practices in hardware security.
