Can hackers get into your fridge? Your smart home may be less safe than you think

Smart home devices are becoming an increasingly targeted landscape for cybercriminals. Internet-connected appliances, once considered purely mechanical, now pose cybersecurity risks beyond traditional systems. Refrigerators, ovens, washing machines, security cameras, and even toothbrushes that connect to the internet can be vulnerable to hacking.

In 2015, researchers showcased how a Samsung smart refrigerator could be infiltrated, highlighting the potential for unauthorized access and control. However, hackers may not always seek to manipulate the device directly; their intentions could range from stealing sensitive information to disrupting services or leveraging the device to breach larger networks.

The majority of cyber attacks on connected devices originate from routers, with other smart home products like security cameras, video doorbells, and thermostats also at risk. Once inside a device, attackers can extract information, manipulate functions, or expose data traveling across the network. A compromised device might alter settings, lock users out, or grant hackers access to other systems on the same network or personal information associated with online accounts.

While critical infrastructure, such as modern vehicles and aircraft, is typically more secure due to extensive safety measures, widespread monitoring, and regulation, household appliances connected to Wi-Fi are often less fortified. To safeguard your devices, experts advise changing default passwords, enabling two-factor authentication, and staying up-to-date with software updates.

Devices that no longer receive security updates should be removed or replaced. Additionally, limiting the number of connected devices and connecting them solely to a local network rather than the wider internet when possible can significantly reduce potential vulnerabilities.
