LG TVs scan local networks; broader spying claims are disputed
Researchers observed tested LG TVs discovering phones and other devices on the same network, a function LG acknowledges, while claims about routine ambient recording remain disputed and must be separated from what an attacker could do after compromising a TV.
The 60-second version
Researchers observed tested LG TVs discovering devices on their local networks; LG acknowledges that function but disputes claims of routine ambient recording.
Key points
- Packet captures and firmware analysis reportedly showed phones, computers, printers, watches and smart-home devices being identified.
- Device discovery can enable casting and smart-home features, but it can also reveal the composition and activity of a household.
- Microphone capture was demonstrated after a TV was compromised, which is a different claim from default product behavior.
- LG says voice and advertising features require consent and that standby wake-word processing remains local unless activated.
Verdict. The network-discovery finding warrants tighter settings and segmentation, while the broader spying claim remains contested pending reproducible technical disclosure.
A Gamers Nexus investigation conducted with Level1Techs and security researchers says tested LG smart TVs discovered phones, computers, printers, watches and other devices on the same local network. LG confirms that its TVs perform device discovery for connectivity, sharing and smart-home functions, but rejects claims that normal operation amounts to constant ambient recording.
What was observedA television can map its digital neighborhood
Ars Technica reports that packet captures from the investigation showed an LG G5 scanning the LAN and finding unrelated staff phones and smartwatches. Malwarebytes says the tested televisions identified phones, PCs, printers, switches and smart-home hardware, and that the team also observed nearby Wi-Fi names, signal information and device-related identifiers.
| Confirmed by LG | Compatible-device discovery on the same network for connection, content sharing and smart-home features |
|---|---|
| Reported by researchers | Broader device inventory, nearby Wi-Fi and logging observations derived from packet captures and firmware analysis |
| Shown after compromise | Microphone access and offline storage followed by later retrieval, according to the investigation |
Discovery alone does not prove that a TV reads files, messages or microphone data from every device it can see. Common local protocols reveal names and capabilities so devices can cast or connect. Even so, an inventory can expose the composition and activity of a household, especially when combined with viewing and advertising identifiers.
The critical distinctionBuilt-in behavior is not the same as an exploit
The investigators also demonstrated microphone capture on a compromised television, including when the display appeared off, and said audio could be held while the internet was unavailable and retrieved later. Malwarebytes notes that some findings concern intended behavior while others depend on vulnerabilities still under responsible disclosure.
That is a serious attack scenario, but it does not establish that all LG televisions routinely record rooms. It shows why a remote-code-execution flaw would have a large privacy impact on hardware that may contain a microphone and remain powered in standby.
LG's responseThe company confirms discovery and denies ambient recording
LG told Tom's Hardware that voice data is processed only when the remote's voice button is held or after a user enables far-field recognition and the wake word is detected. The company says wake-word checking in standby happens locally, discarded audio is not sent to its servers, and automatic content recognition, voice recognition and interest-based advertising require separate opt-in consent.
What owners can doTreat the television as a networked computer
- Install firmware updates and watch for advisories naming affected models and versions.
- Review automatic content recognition, voice, advertising and device-connectivity settings; decline optional agreements that are not needed.
- Place smart televisions on a guest or isolated network when practical, allowing only the local connections needed for casting.
- Distinguish standby from unplugged power when evaluating privacy behavior.
- Look for reproducible packet captures and completed vulnerability disclosures before treating the broadest claims as settled.
The defensible finding is not that every television is always listening; it is that a smart TV has enough access to deserve computer-grade privacy controls.
The practical conclusion is to reduce unnecessary access now and wait for the disclosure process to resolve the contested details. Network discovery is real and acknowledged; routine ambient surveillance across LG's installed base is not established by the evidence currently public.
