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 在广泛使用的ESP32微控制器中发现了一个隐藏功能，攻击者可以利用该功能伪造设备、窃取数据并安装恶意软件，对数百万物联网设备构成威胁。
➁ 此漏洞源于蓝牙主机控制器接口（HCI）中的隐藏命令，这些命令通常用于调试，但可能被恶意利用。
➂ ESP32的制造商乐鑫承认了该问题，但表示这些命令仅用于内部测试。用户被建议进行安全审计并遵循最佳实践以降低风险。
➀ A hidden feature in the widely-used ESP32 microcontroller allows attackers to spoof devices, steal data, and install malware, posing risks to millions of IoT devices.
➁ The vulnerability stems from hidden commands in the Bluetooth Host Controller Interface (HCI), which are typically used for debugging but can be exploited for malicious purposes.
➂ Espressif, the manufacturer of ESP32, acknowledges the issue but claims these commands are for internal testing. Users are advised to conduct security audits and follow best practices to mitigate risks.
