  "account": "Britain’s National Cyber Security Centre (NCSC) head Richard Horne has issued a stark warning to businesses, urging them to urgently bolster their cyber defenses following a series of hacking incidents that targeted supermarkets across Europe. Horne highlighted that outdated technology and artificial intelligence (AI) are giving hostile states and criminals new avenues to identify and exploit weaknesses within organizations' systems. The NCSC chief executive, attached to the cyber intelligence agency GCHQ, emphasized that the issue is not that AI has invented new attack methods, but that long-tolerated vulnerabilities are now being discovered and exploited on an unprecedented scale.\n\nOn Monday, a wave of cyberattacks struck supermarket freezers across Europe, raising temperatures to as high as 50°C and prompting stores to discard significant quantities of spoiled food. Horne criticized decades of underinvestment in \"operational technology\" - systems that govern critical infrastructure such as electricity networks, water supplies, and refrigeration units, which have left Britain with a multitude of vulnerabilities. Speaking to the BBC ahead of a keynote address, Horne stressed that technology underpins all aspects of modern society, yet its reliance often comes with substantial vulnerabilities due to insufficient investment.\n\nMany organizations have extended equipment past its intended lifespan, failing to upgrade systems or isolate them from the internet adequately. Horne pointed out that they have not kept these systems updated or kept them in secure, disconnected compartments, leaving numerous vulnerabilities exposed. AI \"in the hands of our adversaries\" can effectively exploit these weaknesses. European supermarkets in Belgium, Luxembourg, Sweden, Ireland, the Netherlands, Estonia, and Finland were affected by Monday's cyberattacks, which followed similar incidents targeting supermarkets and food suppliers in France in early October. Horne could not definitively attribute the attacks to Russia or Iran but noted that the motive remains unclear, suggesting they might be from state actors or criminal organizations.\n\nHorne called for companies to prioritize technology renewal and advised individuals to keep devices updated, enable automatic updates, maintain offline backups, and use passkeys when possible. While the NCSC provides warnings and intervenes when possible, the ultimate responsibility for safeguarding systems lies with individual organizations. \"We work 24-7. We alert people. We intervene where we can. But at the end of the day, it's your business. It's your life. You need to make the choice and choose wisely,\" Horne stated.",
