Smart TVs are no longer just devices for watching movies and shows. They are internet-connected computers with microphones, apps, advertising systems and access to your home network. That also means they can become a security risk when privacy settings or software protections are not strong enough.
A new investigation has raised concerns about LG TV security flaws, including network discovery, tracking and vulnerabilities that could potentially expose sensitive information. The investigation was carried out by Gamers Nexus with Level1Techs and independent security researchers.
The findings suggest that some LG TV models can identify devices connected to the same network. These may include phones, computers, printers, switches and smart-home devices. The TVs were also reported to collect information about nearby Wi-Fi networks, signal details and device identifiers.
Could an LG TV Listen Even When It Looks Off?
One of the most concerning findings involved the TV’s microphone. Researchers demonstrated that a compromised television could capture audio even when the TV appeared to be switched off.
They also showed a test in which audio was stored while the TV was disconnected from the internet and later retrieved after the connection was restored.
This does not mean every LG TV is secretly recording its owners. However, it shows why internet-connected televisions should be treated like computers rather than simple entertainment devices.
The investigation also reported remote-code-execution vulnerabilities to LG. Full technical details have not been released because the responsible disclosure process is still underway.
How Serious Are These Smart TV Risks?
The biggest concern is not only what information the television collects. A compromised TV could potentially become an entry point into the wider home or office network.
| Smart TV Feature | Possible Concern |
|---|---|
| Microphone | Audio privacy risks |
| Network discovery | Reveals other connected devices |
| ACR tracking | Can identify viewing habits |
| Advertising IDs | May support user profiling |
| Internet connection | Creates another attack surface |
| Software vulnerabilities | Could allow unauthorized access |
Automated Content Recognition, or ACR, is another important privacy issue. It can analyze what appears on or is heard through a TV and create digital fingerprints. These fingerprints may help identify programs, advertisements and viewing patterns.
When combined with network information and advertising data, this could create a detailed picture of a household’s technology and entertainment habits.
How to Protect Your LG Smart TV
There is no need to panic, but a few simple steps can reduce the risk.
First, install firmware updates as soon as they become available. Security updates can fix vulnerabilities that attackers may try to exploit.
Next, check your TV’s privacy settings. Depending on the model, look under areas such as Privacy & Terms or User Agreements. Consider disabling features you do not need, including ACR, personalized advertising, viewing-data collection and voice recognition.
It is also better not to accept every agreement automatically. Read the available consent options and turn off optional data-sharing features whenever possible.
For extra protection, connect your smart TV and other IoT devices to a separate guest or IoT network. This can limit what a compromised TV can access on your main network.
Finally, review your router settings. Disable UPnP if you do not genuinely need it and never expose TV services directly to the internet.
The Bigger Lesson for Smart TV Owners
The latest investigation is a reminder that smart TVs deserve the same security attention as phones, laptops and other connected devices. LG TV security flaws may be the immediate concern, but the wider issue affects the entire smart TV industry.
Keeping software updated, limiting data collection and separating smart devices from your main network can go a long way toward protecting your privacy without giving up the convenience of a smart TV.
