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.

This isn't a backdoor. Just a company trying to make a name for themselves by sensationalizing a much smaller discovery.

Fukin dmnit! I just spent the last several months fine tuning a PCB design supporting this platform. I have , what i believe to be my last iteration, being sent to fab now. I have to look i to this. My solution isnt using bluetooth, so i dont know if im vulnerable.

Its not a backdoor, you're most likely fine.

Weird that they removed the reference to ESP32, one of the most common and widely known microcontrollers, from the headline.

This turned racist / xenophobic real quickly.

There have been several other posts about this without mentioning China at all, especially in the post itself.

No where in the article does it say "chinese", literally anywhere.

Check your racism.

Edited to remove where I stated it was manufactured. I did a quick search and found a couple mentions, but did not thoroughly check sourced. Apologies.

No. Fuck the Chinese. All 17billion of them.

I agree we shouldn't be racist against Chinese people, but you're ignorant. From wikipedia: ESP32 is created and developed by Espressif Systems, a Chinese company based in Shanghai, and is manufactured by TSMC using their 40 nm process.It is a successor to the ESP8266 microcontroller.

So it's designed/developed in China and manufactured in Taiwan; not China.

I actually wanted to keep the title short, but I think it would be better to edit the title to avoid any confusion to make it clear that it's manufactured in China, rather than saying it in the current way.

Edit: I edited the title to reflect the details better.
