Overview
- This week a technical investigation led by Gamers Nexus with Level1Techs and independent researchers published packet captures and firmware analysis that they say show certain LG TVs use Automatic Content Recognition to sample audio and video across inputs.
- The testers reported the TVs scan local Wi‑Fi to identify secondary devices such as phones and watches and that those device fingerprints can be paired with ACR data to build detailed household profiles.
- Investigators say some sets recorded voice data beyond wake‑word windows, produced readable transcripts, and could store recordings offline for later upload when the TV regained internet access.
- Researchers reported security flaws, including alleged critical remote‑code‑execution vulnerabilities, to LG and are withholding full technical details while LG issues patches and responds to the disclosure.
- LG has denied that TVs record ambient conversations outside user‑activated voice features and said ACR is opt‑in, and outlets and guides advise users to disable ACR and hands‑free voice, isolate TVs on guest networks, install firmware updates, or disconnect smart functions.
