The Royal Borough of Kensington and Chelsea confirmed hackers copied historical data during a cyber attack discovered Monday morning. The council quickly shut down systems after detecting unusual activity, emphasizing that while data was copied, it wasn't stolen and remains accessible to them. The breach also affected Westminster City Council and Hammersmith and Fulham Council through shared IT arrangements. Police are investigating with no arrests made yet. RBKC is checking whether personal or financial details were compromised, warning residents to stay vigilant against suspicious communications. Council services continue running despite some disruptions to phone lines and online systems. **Source:** [BBC](https://www.bbc.com/news/articles/crmd74j4ezpo)
