Smart homes promise unmatched convenience, from voice-controlled lights to app-monitored doorbells. But as more households embrace connected technology, a growing number of cybercriminals are learning how to exploit it. While these devices may seem advanced, many come with weak default settings or outdated firmware that makes them vulnerable. Even more concerning, you may have no idea your privacy has been breached until it’s too late. If you rely on smart devices, it’s time to understand which ones hackers can bypass—and how to protect yourself.
1. Smart Locks With Weak Encryption
Smart locks seem like a high-tech upgrade from traditional keys, but many models have glaring vulnerabilities. Some use outdated encryption methods, which can be cracked with basic hacking tools. Others allow Bluetooth or Wi-Fi access with minimal authentication, meaning nearby hackers can intercept unlock signals. A determined cybercriminal doesn’t need to break a window—just your network. Always choose smart locks with strong encryption, two-factor authentication, and regular firmware updates.
2. Wi-Fi Security Cameras Without Proper Password Protection
Indoor and outdoor smart cameras are designed to boost security, but ironically, they’re often the first devices hackers target. Many people never change the factory-set username or password, making it easy for bad actors to gain access. Once inside, hackers can watch live feeds, track your habits, or even speak through two-way audio features. The worst part? You may never know it’s happening. Always update login credentials and enable encryption for any connected camera.
3. Smart Doorbells That Leak Data
Smart doorbells like Ring or Nest offer convenience and security, but they also gather tons of personal data. Some models transmit unencrypted footage or store video in the cloud without strong safeguards. Hackers can exploit these weaknesses to view your doorstep activity—or worse, access your home network. Data breaches have already exposed users’ login details in the past. To stay safe, enable two-factor authentication and check your device’s privacy settings regularly.
4. Voice Assistants Listening to More Than You Think
Amazon Alexa, Google Assistant, and other voice-activated devices are incredibly useful—but also pose a huge privacy risk. These gadgets constantly listen for a “wake word,” which means they can pick up and store conversations unintentionally. Hackers who gain access to your assistant can listen in or use voice commands to control other devices. Some have even used synthetic voice attacks to bypass basic security. To minimize the risk, disable features you don’t use and review your voice history frequently.
5. Smart Thermostats That Reveal Your Routine
Smart thermostats like Nest and Ecobee can learn your daily patterns to optimize energy use. But what’s convenient for you is also convenient for hackers. If someone breaches your account, they can see when you’re home—or more importantly, when you’re not. This information can be sold or used to plan physical break-ins. Set strong, unique passwords and avoid linking your thermostat to public platforms or unsecured networks.
6. Smart TVs With Weak Network Settings
Smart TVs can stream your favorite shows, but they also come loaded with apps, voice recognition, and internet access—all of which can be entry points for hackers. Many users never configure their network settings properly or skip firmware updates, leaving vulnerabilities exposed. Hackers have been able to access microphones, cameras, and app data through poorly secured TVs. If your TV has features you don’t use, disable them. Keep it updated and be mindful of what it’s connected to.
7. Smart Plugs and Outlets With No Security Layer
Smart plugs are cheap, easy to use, and widely available—but they’re also one of the most overlooked security risks. Some models use unencrypted communication, which hackers can intercept to control appliances or devices connected to them. Once inside your smart outlet, attackers may attempt to gain access to other parts of your network. This is especially concerning if you connect high-powered devices like heaters or ovens. Stick to well-reviewed plugs from reputable brands and look for those with encrypted protocols.
8. Baby Monitors That Can Be Hijacked
Modern baby monitors often come with video feeds, motion alerts, and even temperature sensors—all accessible via smartphone. Unfortunately, many of them are just as easy for hackers to access. Reports have surfaced of strangers speaking through monitors or watching children in real time. In many cases, the breach occurred because of default passwords or outdated software. Always secure your monitor with a strong passphrase and check for firmware updates often.
Your Smart Home Shouldn’t Be Easy to Outsmart
While smart home tech offers impressive convenience, it’s important not to sacrifice security in the name of automation. Every connected device creates a new pathway for hackers to exploit if it’s not properly protected. Fortunately, many of these vulnerabilities can be closed with strong passwords, encryption, and regular updates. Don’t assume your devices are safe just because they’re “smart”—assume nothing, and secure everything.
