近期多地公安、国安部门发布安全提示,指出手机蓝牙长期开启存在安全风险,可能被不法分子利用技术漏洞窃取个人信息或实施窃密行为。
近期,多地公安、国安部门发布安全提示,手机蓝牙长期保持开启状态暗藏风险。听听公安部门怎么说。
国安部门提示,不法分子可能利用蓝牙技术漏洞,非法窃取个人信息,甚至实施窃密行为,既威胁公民个人隐私,也会对国家秘密安全构成风险。不法分子会在公共场所假借会议信号广播、协议认证、免费Wi-Fi等名义,诱导群众连接陌生设备。一旦建立连接,就可能出现通话被远程窃听、设备定位遭获取、各类个人敏感信息被盗取等安全隐患。
揭秘蓝牙窃密手段
静默配对或钓鱼窃取
不法分子究竟是如何借助蓝牙,把手机变成监听工具窃取手机数据的?来听听网络安全专家的解读。
中国计算机学会计算机安全专委会委员 王媛媛:如果你的手机或者是耳机存在蓝牙漏洞,这个时候,攻击者在几秒钟之内,就可以完成静默配对,不需要你点击任何的同意按钮,它就可以实现自动配对。这时,可以激活你手机或耳机上的麦克风监听你的对话,这是一个比较典型的攻击手段。
另外专家表示,手机蓝牙开启后会持续向外广播信号,不法分子可以凭借该信号,判断目标是否出现在附近,以此实现行踪轨迹追踪。
中国计算机学会计算机安全专委会委员 王媛媛:第三类属于钓鱼窃取。在公共场所时,有可能会收到一些特殊的蓝牙配对请求,一旦点击了同意配对,可能对方马上就会给你发过来一些文件,比如照片,比如一些可能绑了木马的文件,如果你打开了,手机可能已经被植入了木马,那么你手机里浏览器保存的账号密码以及你手机里的一些重要个人信息文件有可能就被窃取走了。
防范蓝牙隐患
及时更新系统 勿随意配对
专家表示,抵御蓝牙攻击有两个简单可行的办法,一是保持手机系统为最新版本,二是公共场所切勿随意和陌生设备配对。如果不慎在公共场所接收了陌生人的蓝牙传输文件,务必使用安全软件开展病毒查杀。

Lenovo launched the Yoga Tab Gen 2 and Yoga Tab Plus Gen 2 tablets at 2026 IFA, promising to provide 7 years of system and security updates, tying Samsung. On the other hand, Apple’s upcoming iPadOS 27 will raise the hardware threshold and eliminate many old iPad models.
The Scientific Intelligent Material Creation Center of the University of Science and Technology of China has launched the "Lingjing Creation" scientific research intelligent platform, which relies on robots and artificial intelligence to realize automated experiments and promotes the evolution of material science research toward platform-based and open sharing. It has served many units around the world.

China is building a digital ID card management system for new energy vehicle power batteries, which connects 96 items of full life cycle information through 24-bit coding. This system covers production, operation and maintenance, recycling and other aspects, and will face the challenges of standard convergence and mutual recognition with the EU Battery Passport.
The "National Anti-Fraud AI" APP independently developed by the Criminal Investigation Bureau of the Ministry of Public Security under the guidance of the Shanghai Public Security Bureau has been launched. It integrates large language, multi-modal model and agent technology to provide three major functions: AI intelligent question and answer, anti-fraud information and anti-fraud dictionary. It can be downloaded and used in the mobile application market, WeChat and Alipay mini-programs, aiming to improve the informatization and intelligence level of preventing telecom network fraud.

A study by Florida International University in the United States found that commercially available smart watches have a typical error of 15% to 25% in estimating exercise calorie consumption. The higher the body fat rate, the more inaccurate the measurement. Researchers caution that it should only be used as a trend reference.
Reporters investigated and found a large number of unlabeled AI-generated videos pretending to be traffic police, monks and other professionals to promote products. The China Academy of Information and Communications Technology’s assessment showed that the probability of AI-generated videos is as high as 96%. The Beijing Internet Court pointed out that such cases have increased year by year, and the reduced cost of AI fraud has caused the problem to spread to traditional industries. Experts recommend using “eyes, ears, and hands” to identify AI videos to prevent being deceived.
