According to the BBC, a recent cyber-attack on refrigeration systems in supermarket chains across several European countries has sounded an alarm regarding the security of Internet of Things (IoT) devices. Experts warn that while internet connectivity facilitates remote management, it can also open doors for cyber attackers. Ciaran Martin, former chief executive of the UK's National Cyber Security Centre (NCSC), emphasized that manufacturers must implement stricter security standards for their products. In the UK, research by UK Cyber Defence indicates that over 800 refrigeration and building-control interfaces are accessible via the public internet, potentially exposing them to attacks. Security experts warn that these vulnerabilities are not limited to fridges and could extend to cars, power plants, and water networks, which could suffer irreparable damage if security protocols are not followed.
