Uncovering Privacy Issues in LG Smart TVs
An investigation has revealed that LG smart televisions scan local networks to identify nearby devices and record audio through their microphones even when the screen is turned off—all without user permission. These collected data are then sent to LG's advertising division. Independent security experts conducted tests primarily on LG OLED models, including the G5, confirming these privacy breaches. LG TVs employ Automated Content Recognition (ACR) technology to track what users watch. Due to these concerns, specialists advise disconnecting LG smart TVs from the Internet to mitigate risks.
The research found that LG smart TVs actively scan local networks to detect nearby phones and other devices without notifying users. Tests demonstrated that these TVs can capture audio through their microphones while the screen is off, then upload the recordings once the device reconnects to the Internet. A recent 135-minute video by Gamers Nexus further validates the ongoing network scanning and audio recording activities. This extensive testing involved collaboration with Level1Techs and independent cybersecurity researchers.
Details of Data Collection and Its Implications
Network packet captures using Wireshark exposed that LG smart TVs continuously probe local networks for devices unrelated to the TV itself. The information gathered includes:
- Internal IP addresses
- Names and signal strengths of nearby Wi-Fi networks
- Location-related data
This information is transmitted to LG Ad Solutions, the company's targeted advertising branch. LG has reportedly sold around 216 million smart TVs globally. In the United States alone, LG's advertising division reportedly has access to 363 million secondary addressable devices.
LG TVs use ACR technology that generates digital fingerprints of audio and video content to monitor viewing habits. Even in standby mode with the screen off, these TVs can record clear audio through the microphone. If disconnected from Ethernet, voice inputs are stored locally and uploaded once the network connection is restored. Experts recommend disconnecting LG smart TVs from the Internet and opting for external streaming devices instead. LG has not yet issued a statement regarding these findings.
Separately, recent investigations have highlighted privacy concerns involving Meta smart glasses users and workers in Kenya tasked with labeling AI training data. These individuals reportedly encountered sensitive material, including videos featuring nudity and financial information. Such incidents emphasize the critical importance of data privacy in today's tech environment.
This situation raises significant concerns about personal data privacy and consumer protection in the era of smart gadgets. The findings underscore the need for strict oversight of technologies that handle personal information and emphasize the importance of informed usage of connected devices. Consumers should be aware of potential privacy risks and take proactive steps to safeguard their information.
