At its core, the ESP32 chip is not much more than an integrated circuit, a huge mass of transistors sealed inside an epoxy resin package with some leads. Of course, most of us won’t buy discrete ...

The bluetooth chip is called ESP32 and is manufactured by the China-based company Espressif. According to researchers, the ESP32 is "a microcontroller that enables WiFi and Bluetooth connection." ...

It’s still an ESP32, but one that’s more useful, and it’s worth a closer look because we expect it to figure in quite a few projects. Espressif’s block diagram for the chip. Sadly the data ...

Researchers have found undocumented commands in a popular bluetooth chip which is inside over a billion devices worldwide. The secret commands are in the ESP32 chip, which is made by Espressif.

"Our findings would allow to fully take control over the ESP32 chips and to gain persistence in the chip via commands that allow for RAM and Flash modification." "Also, with persistence in the ...

A hot potato: The ESP32 chip, found in over a billion devices worldwide, contains undocumented vendor-specific commands that could potentially be misused to access device memory and manipulate ...

Turns out that Espressif’s ESP32 chip has been hiding 29 secret commands that nobody was supposed to know about. These aren’t just your garden-variety hidden features either. We’re talking ...

The ESP32 chip allows connectivity through Wifi or Bluetooth and can be found in millions of the Internet of Things (IoT) devices. At RootedCON, a notable Spanish cybersecurity conference in ...
