ESP芯片中的安全漏洞！是什么？如何应对？Security Bug in ESP Chips! What is it? How to Handle it?
➀ 在广泛应用于物联网设备的ESP32微控制器中发现了一个隐藏功能，该功能可能带来设备欺骗、数据窃取和恶意软件安装等潜在安全风险。
➁ 此漏洞源于蓝牙主机控制器接口（HCI）协议中的未记录命令，攻击者可能借此绕过标准的安全检查并危害关键系统。
➂ 为降低风险，建议包括审计固件、禁用未使用的蓝牙服务、确保固件更新的安全性以及实施强身份验证机制。
➀ A hidden feature in ESP32 microcontrollers, widely used in IoT devices, poses potential security risks including device spoofing, data theft, and malware installation.
➁ This vulnerability stems from the undocumented commands in the Bluetooth Host Controller Interface (HCI) protocol, which could allow attackers to bypass standard security checks and compromise critical systems.
➂ Recommendations to mitigate risks include auditing firmware, disabling unused Bluetooth services, ensuring secure firmware updates, and implementing strong authentication mechanisms.
