  "account": "A cyberattack targeting connected refrigeration systems in French supermarkets affected temperatures and led to food losses and fires. A separate cyber incident at TFG London disrupted IT systems and online services. These incidents highlight the importance of securing software that controls real-world operations. Developers and security engineers must consider the physical consequences of security failures. Operational technology, such as refrigeration controllers, industrial automation systems and building management systems, has different availability and safety requirements compared to typical web applications. Connectivity expands the attack surface, as every unnecessary connection creates potential exposure. A compromised controller may change operating parameters based on permissions and safeguards. A multi-layered security approach is necessary, including asset inventory, network segmentation, strong access control, monitoring, and safe recovery plans. Security testing for operational systems must account for physical consequences. The separate retail incident demonstrates the importance of availability and business continuity in cybersecurity. Developers in Nigeria should focus on understanding secure software practices, authentication, networking, secure configuration, monitoring, and incident response to build resilient systems.",
  "summary": "Most cybersecurity headlines involve compromised accounts, stolen credentials, ransomware or leaked databases. But what happens when an attacker gains control of a system responsible for keeping food cold? On October 12, 2026, a cyberattack targeting connected refrigeration systems affected hundreds of French supermarket locations. Some cold-storage temperatures reportedly reached 50°C, with food…",
