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.
So explained to me, a tech illiterate in comparison, this is China bad scaremongering?
‘Backdoor’ sounds malicious with intent.
The article is a security company trying to hype their company with a theoretical attack that currently has no hypothetical way to be abused
The article has an update now fixing the wording to “hidden feature” but, spoilers, every BT device has vendor specific commands.
The documentation of the part just wasn’t complete and this companies “fuzzing” tool found some vendor commands that weren’t in the data sheet
The China part just came from OP
thank you
