Tarlogic Security has detected a backdoor in the ESP32, a microcontroller that enables WiFi and Bluetooth connection and is present in millions of mass-market IoT devices. Exploitation of this backdoor would allow hostile actors to conduct impersonation attacks and permanently infect sensitive devices such as mobile phones, computers, smart locks or medical equipment by bypassing code audit controls.
Update: The ESP32 "backdoor" that wasn't.
While technically true, that’s not what I meant. For example, Tesla Model 3 has AMD Ryzen chip. It is a full fledged computer CPU. Although my Toyota surely has a computer onboard, it’s nowhere close to this level of tech in the Tesla. EVs from China are at the same or higher level tech-wise compared to Teslas.
