In the digital age, almost everything in your home is connected to the internet. From smart TVs to doorbell cameras, thermostats, light bulbs, speakers, and even stuffed animals. The convenience these devices provide often comes with a silent risk: they have become perfect targets for cybercriminals.

1. Spy Plush Toy

In 2017, a cute teddy bear launched by Fisher-Price became the epicenter of one of the most serious leaks. The toy, which allowed parents and children to send voice messages, stored the recordings on servers without adequate protection. Attackers accessed more than two million private audio recordings and personal data belonging to minors. What seemed like a resource to strengthen family communication turned into a privacy nightmare.

2. “Smart” Thermostat

One of the most unusual attacks also occurred in 2017, when a Las Vegas casino was hacked using a smart thermometer in a fish tank. This device, connected to the Internet to control the temperature, food, and cleanliness of the aquarium, was the gateway to access the establishment's database.

The hackers stole sensitive information, including the names of the casino's high rollers. A simple fish tank was enough to bypass all conventional security measures.

3. Security Cameras

In 2019, Ring cameras, very popular for their integration with smartphones, were the target of massive attacks. Many users used weak or repeated passwords, which allowed attackers to access the accounts and control the cameras.

The most chilling case occurred in Texas, where a woman heard an unknown voice speaking from the camera installed in her daughter's room. The supposed "technical support" demanded 50 Bitcoins and then threatened her, claiming to be near her house. The victim turned off the camera and removed the battery for safety.

4. Home Devices

In 2016, Mirai was discovered, A botnet comprised of more than 600,000 household devices such as routers, cameras, and video recorders. These devices had been infected with malware and used to launch a massive DDoS attack against Dyn, the DNS system provider. The result was that sites like Twitter, Netflix, Spotify, Amazon, and many more were inaccessible for hours. Millions of households unwittingly participated in one of the largest internet attacks in history.

5. Hacked Cars

It's not just household devices that are at risk. In 2015, security experts Charlie Miller and Chris Valasek demonstrated how they could take remote control of a smart car. They managed to turn on the air conditioning, manipulate the radio, and activate the windshield wipers.

Their ethical test was so effective that the automaker had to recall 1.4 million vehicles in the US. Although there was no malicious intent, the case highlighted how vulnerable a connected car can be.

How to protect your smart home?

Although they may sound extreme, these cases are real and increasingly frequent. ESET, a company specializing in cybersecurity, emphasizes that the best defense is prevention. Changing default passwords is key, as well as keeping devices always updated. It is also recommended to disable unnecessary services, properly configure each device, and activate two-step authentication whenever possible.

Today, more than ever, it is important to understand that any device connected to the Internet can become an easy target if we don't take the necessary measures. Technology in the home is here to stay, but it's up to us to properly close the digital doors that we use every day without even noticing.
