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.

    Thanks for the link, this article is more clear compared to the posted above.

    I’m more interested to the scope of the exploit whether it could touch the flash of the controller or not as you can also do OTA update through the BLE component.
