Royal Borough of Kensington & Chelsea (RBKC)

Royal Borough of Kensington & Chelsea (RBKC)

The Royal Borough of Kensington & Chelsea (RBKC) faced a coordinated cyberattack alongside multiple London boroughs, causing severe disruptions to critical public services. Key systems, including phone lines, were compromised, forcing the activation of emergency response plans and direct intervention from the National Cyber Security Centre (NCSC). The attack strained resident communications, particularly for vulnerable service users, and required external incident-response specialists to assess damage, recover systems, and safeguard sensitive data. The Information Commissioner’s Office (ICO) was notified due to potential data breach risks. The incident exposed systemic vulnerabilities in shared-service models, where interconnected legacy infrastructure across boroughs allowed the attack to escalate rapidly. With over 2,400 suspected breaches recorded across 27 councils in 2024, the attack underscores the growing threat of AI-driven, industrial-scale cybercrime targeting underfunded local authorities. Recovery efforts highlighted the urgent need for modernized digital resilience, as outdated 2000s-era technology stacks proved incapable of mitigating cascading failures. The disruption threatened core municipal operations, eroding public trust and operational continuity.
