The Royal Borough of Kensington and Chelsea confirmed that historical resident, customer, and service-user data was copied and taken away after a cyber-attack, creating a risk that sensitive records could reach the public domain. The disclosure matters because the council is still checking whether the exposed material includes personal or financial details and has warned about follow-on social engineering attempts. The event also points to broader operational stress, with services still being restored and some functions remaining disrupted.
