Hackers have targeted refrigeration systems at many French supermarkets by taking advantage of the increased connectivity of devices that were once mainly mechanical. Many appliances, such as refrigerators, heating systems, and security cameras, can now be monitored and controlled online, making them vulnerable to cyber attacks. If a device is connected to the internet, it can potentially be hacked. For example, researchers showed at a hacking conference in 2015 how a Samsung smart refrigerator could be compromised.
The most commonly targeted devices include internet-connected security cameras, smart locks, thermostats, and various smart appliances. Routers, in particular, are involved in over three-quarters of attacks on connected devices. As more manufacturers add internet connectivity to once-mechanical products, the opportunities for hackers increase.
Once hackers gain access to a device, they can either gather information or take control of it. For example, they could use a hacked camera to view the inside of a home or control a thermostat, affecting heating. A compromised appliance might disrupt temperature settings or lock users out of their accounts. More serious cases allow hackers to access other systems on the same network or steal personal information.
Cybersecurity researchers have shown that connected vehicles also have vulnerabilities. For instance, researchers took control of a moving Jeep through its internet system in 2015. While modern vehicles have safety measures, critical infrastructure like power and water networks is more secure than household devices.
To protect devices, cybersecurity experts suggest changing default passwords, enabling two-factor authentication, and regularly updating software. They recommend removing outdated devices, keeping most on a local network, and limiting internet connections. Fewer connected devices mean fewer entry points for attackers.
