Everyday IoT gadgets face growing cyber-security threats as hackers exploit connectivity

Recent incidents show that the expanding internet connectivity of appliances, from refrigeration systems in French supermarkets to household smart devices, creates fresh entry points for cyber-criminals. Hackers can infiltrate devices linked to cloud services or home networks, allowing them to harvest data, disrupt operations, or commandeer hardware, such as altering thermostat settings or disabling cameras. Demonstrations have proved a Samsung smart refrigerator could be compromised, and routers account for the bulk of attacks on connected gear.

Although researchers have remotely taken control of vehicles, critical utilities like power and water grids retain multiple security layers, making them harder targets. Security specialists recommend users replace default credentials, enable two-factor authentication, apply updates promptly, and limit the number of internet-connected devices. Keeping devices on a local network and retiring unsupported products further reduces risk.
