  "account": "Supermarkets across Europe have recently fallen victim to a suspected cyber-attack targeting their refrigeration and freezer systems, sparking concerns about the security of internet-connected devices. Smart appliances encompass a wide range of household items, such as fridges, heating systems, and washing machines. While these connected devices are easier to control remotely, any device that goes online could potentially be exploited by malicious actors. Despite this, big brands typically invest significant resources into securing their technology. However, this doesn't guarantee that devices are entirely immune to exploitation. In 2015, researchers exposed a vulnerability in a Samsung smart fridge that could enable them to intercept internet traffic. However, no evidence suggests that domestic appliances are specifically targeted in the recent supermarket cyber-attacks.\n\nCiaran Martin, the former chief executive of the UK's National Cyber Security Centre (NCSC), emphasizes the need for manufacturers to prioritize the security of connected devices from the outset. He urges consumers to keep their devices updated and enable multi-factor authentication wherever possible. Since April 2024, UK law has mandated that manufacturers of certain smart consumer devices meet minimum cyber security standards, including requirements around passwords and software updates. The NCSC is collaborating with international partners and industry to investigate the supermarket incidents, though they are unaware of any impact on the UK.\n\nResearchers from UK Cyber Defence have identified over 800 refrigeration and building-control interfaces associated with British retailers that can be accessed over the public internet. While this does not necessarily indicate that these systems can be hacked, it could leave them vulnerable to attacks exploiting weak passwords or software flaws. The UK government has engaged in discussions with major food retailers to enhance cyber resilience following earlier attacks on supermarkets. Helen Dickinson, chief executive of the British Retail Consortium, acknowledges cyber incidents as a significant concern for retailers, who are working alongside the NCSC to share intelligence and bolster their defenses.\n\nTom Hegel, a researcher at cyber-security firm SentinelOne, stresses the importance of retailers clarifying responsibility for the security of connected equipment. He argues that the question retailers must answer is who owns the security of the technology, not just who is responsible for repairing it. Internet connectivity can enhance the convenience of everyday technology, but security must keep pace. Once an attacker gains control over these systems, legitimate functions like defrosting can be misused to cause disruption, potentially destroying physical stock. Outside of the home, connected technology manages industrial machinery and vehicles, as well as remote monitoring in industrial settings. Cyber security expert Ken Munro points to a 2015 demonstration where researchers remotely hacked a Jeep through its internet-connected entertainment system, leading to improvements in vehicle security. He believes that while UK utilities generally secure their connections, standards may vary internationally. His primary concern lies with smaller, less-funded utility companies that may still rely on outdated, vulnerable equipment. Without adequate protections, any internet-connected factory or equipment, ranging from car manufacturers to electricity or transport infrastructure, could face similar risks. Olivier Daloy, a cybersecurity expert at Zscaler, agrees, emphasizing the potential vulnerabilities of any internet-connected system.",
