Undocumented Commands Found In Bluetooth Chip Manufactured in China Used By a Billion Devices.

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.
Not the first time a backdoor was found on Chinese made hardware and it won‘t be the last time. Decoupling can‘t happen quickly enough.
Which government's backdoors would you prefer?
"We know you have a choice in oppressive governments, so we appreciate you choosing ours."
None of them, that's why the only things in my house that connect to the internet are my computers, game consoles, and cell phone
I guarantee all off those have components from manufacturers that a government could pressure for a backdoor.
You are correct, and it doesn't change my stance at all. It's still worth it to mitigate risk even if you can't mitigate all risk.
Like, the fact that my 3d printer is already a fire hazard does not justify leaving a bunch of candles unattended
Not sure if joking or naive...
Like I said 6 hours ago, just because I can't mitigate all of the risk doesn't mean that I shouldn't mitigate as much as I reasonably can.
My 3d printer is a fire hazard, but that's no excuse for leaving a bunch of candles unattended.
Ah I missed the other comment, my client still had a cached view apparently. And definitely true regarding mitigation, your phrasing just read funny to me :)
True, but the ESP32 is used by a lot of devices. This backdoor is pretty huge in scope of devices impacted.
It depends on what the method of attack is. I'm not seeing anything saying that it would be possible to exploit wirelessly, so this could easily be mostly a non-issue.
I mean, most users here are browsing using a device with an AMD or Intel CPU, both with known backdoors. Not the first time a backdoor was found on American made hardware and it won't be the last.
