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.

    Open source stack will not prevent this. It’s not even a backdoor, it’s functionality that these researches think should be hidden from programmers for whatever reason.

    Open source devices would have this functionality readily available for programmers. Look at rtl-sdr, using the words of these researches, it has a “backdoor” where a TV dongle may be used to listen to garage key fobs gasp everyone panic now!
