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.
Just wait until a jester creates a software that sends an erase flash backdoor command to any BT device it sees.
One of my friends is a type I diabetic. He had some sort of smart thingamajig in his teenage years for measuring blood sugar, so you could monitor it over time or warn your family if you’re in some critical situation.
The jester may mean simply to prank, but they may well have blood on their hands if they fuck up medical devices such as that one.
And runs with an USB cable flashing other peoples ESPs to ruin everyone’s day
