安全研究人员发现LG智能电视存在严重隐私问题，即使在屏幕关闭或离线状态下仍在持续记录用户数据26。根据调查，这些电视会扫描本地网络设备、捕获麦克风音频并识别用户正在观看的内容26。LG全球销售的约2.16亿台智能电视受到影响2。研究人员发现，即使断开以太网连接，电视仍会在本地保存语音输入，一旦恢复网络连接就将文件上传2。
收集到的数据被输送至LG广告部门，该部门声称在美国可追踪3.63亿台联网设备2。调查由Gamers Nexus、Level1Techs和独立安全研究人员合作进行，测试对象为零售版LG OLED电视6。研究人员还在webOS中发现了远程代码执行漏洞，目前正在进行负责任的披露流程2。安全专家建议用户立即断开LG电视的网络连接3。
Security researchers have uncovered serious privacy and security vulnerabilities in LG smart televisions, revealing that the devices continue collecting and transmitting sensitive user information even when disconnected from the internet or in standby mode.26 The investigation, conducted by YouTube channels Gamers Nexus and Level1Techs alongside independent security researchers, discovered that LG's approximately 216 million smart TVs globally engage in extensive data harvesting.2
The findings detail how LG televisions scan local Wi-Fi networks to identify nearby devices, record audio through their microphones, and use audio and video sampling to identify content users are watching.26 Notably, even after being disconnected from ethernet, the TVs continue capturing voice input locally and upload these files once network connectivity is restored.2 The collected data—including information about local network devices, neighboring Wi-Fi network names and signal strength, and location data—is sent to LG's advertising division, which claims the ability to track 363 million connected devices in the United States alone.2
Researchers also identified a remote code execution vulnerability in the webOS platform that could allow unauthorized access to the televisions.2 The discovery prompted security experts to recommend that users immediately disconnect their LG TVs from the internet.3 A two-hour video investigation by Gamers Nexus detailed allegations that the televisions can function as eavesdropping devices through their advertising features.5 The investigations noted that Serge Matta, LG's advertising sales division president, was barred by the SEC from operating a company for ten years due to fraud-related charges.5
