Londoners told to be vigilant with messages after cyber

A London council has urged thousands of residents to be “extra vigilant” when receiving calls, emails or text messages after confirming that data had been taken in a cyber-attack.

The Royal Borough of Kensington and Chelsea (RBKC), which has 147,500 residents, said some data had been copied from its systems in an attack this week. The council said it believed the theft related to “historical data” but it was checking whether it contained any personal or financial details of residents, customers or service users.
