By this point, many of us have had the experience of mentioning a product or service out loud during a conversation, only to have an ad for that very thing pop up on a smart device mere moments later. And, although you may have gotten used to the idea of your gadgets keeping tabs on you, you might not realize that your new smart TV’s monitoring capabilities make it extra vulnerable to hackers.

KATV reports that the Portland, Oregon branch of the FBI released guidelines last week as part of its “Tech Tuesday” initiative to warn people about the risk of hackers gaining access to unsecured televisions through the routers. Because smart TVs likely have microphones and even cameras, successful hackers could do anything from petty mischief to serious stalking.

“At the low end of the risk spectrum, they can change channels, play with the volume, and show your kids inappropriate videos,” the FBI says. “In a worst-case scenario, they can turn on your bedroom TV’s camera and microphone and silently cyberstalk you.”

Before you head back to Best Buy, brandishing your receipt and begging for a refund, there are a number of safety precautions you can take to make yourself less of an easy target for cyberattacks.

The first step is knowing exactly what features your TV has, and understanding how to control them—the FBI recommends doing an internet search with the model number and the words microphone, camera, and privacy.

After that, you should delve right into those security settings. Disable the collection of personal information if you can, and learn how to limit microphone and camera access. If you don’t see an option to shut off the camera, black tape over it does the trick.

And, even if it’s not the most riveting reading material, it’s worth perusing the fine print on your device and streaming services to find out what data they collect, where they store it, and how they use it.

Check out all of the tips here, and then see what other everyday objects might be susceptible to hackers.
