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.
Since when HCI is backdoor ? Someone doesn’t understand how bluetooth works. HCI allows for vendor extensions by design. https://www.bluetooth.com/wp-content/uploads/Files/Specification/HTML/Core-54/out/en/host-controller-interface/host-controller-interface-functional-specification.html
That is a big one. IoT lives off ESP32.
Yeah. We found the thing we were pretty sure was there!
Though, if it’s really just local debug commands, then the usual “malice vs stupidity” debate is still up for grabs.
And then there is trump, the illegitimate president, Russian stooge, trying to repeal the CHIPS act.
Here is hoping this will at least make it easier to take back control of tuya devices
Well, at least nobody uses that tech. /s
