“We would like to clarify that it is more appropriate to refer to the presence of proprietary HCI commands—which allow operations such as reading and modifying memory in the ESP32 controller—as a “hidden feature” rather than a “backdoor.” concludes the report. “The use of these commands could facilitate supply chain attacks, the concealment of backdoors in the chipset, or the execution of more sophisticated attacks. Over the coming weeks, we will publish further technical details on this matter.”
