近日，中国国家安全部发布安全提醒，指出智能手机的“隔空投送”（AirDrop 或类似近场文件传输功能）功能可能暗藏安全风险。该功能虽便于用户在近距离内快速共享照片、文件等数据，但若设置为“所有人可发现”或未加密传输，极易被不法分子利用，用于窃取敏感信息、传播恶意内容，甚至实施网络钓鱼或间谍活动。国安部强调，在公共场所（如地铁、商场、机场等）使用此类功能时，应将设备设为“仅限联系人”或完全关闭接收权限，避免未知设备自动连接。同时，用户应定期检查设备的隐私设置，不随意接受来源不明的文件，并及时更新操作系统以修补安全漏洞。此次提醒旨在提升公众对新型数字安全隐患的认知。随着无线通信技术普及，看似便捷的功能背后可能隐藏着信息泄露风险。国家安全不仅关乎宏观战略，也体现在每个公民的日常用网习惯中。只有增强防范意识，才能筑牢数字时代的安全防线。
Recently, China’s Ministry of State Security issued a security advisory warning that the ‘AirDrop’ feature (or similar near-field file-sharing functions) on smartphones may pose hidden security risks. While this feature allows users to quickly share photos, documents, and other data over short distances, it can be exploited by malicious actors if set to ‘Everyone’ or used without encryption—potentially leading to sensitive data theft, dissemination of harmful content, or even phishing and espionage activities.The Ministry emphasized that when using such features in public places—such as subways, shopping malls, or airports—users should configure their devices to ‘Contacts Only’ or disable receiving altogether to prevent unauthorized connections from unknown devices. Additionally, individuals should regularly review privacy settings, avoid accepting files from unverified sources, and keep their operating systems updated to patch known vulnerabilities.This advisory aims to raise public awareness about emerging digital threats. As wireless communication technologies become increasingly common, seemingly convenient features may carry significant risks of information leakage. National security is not only a matter of strategic importance but also hinges on the daily digital habits of every citizen. Only by strengthening vigilance can we build a robust defense in the digital age.
