Three London councils - Kensington and Chelsea, Westminster, and Hammersmith and Fulham - were struck by a cyber attack Monday that potentially compromised residents' personal data. The councils share IT systems, allowing attackers to move between networks quickly.

Officials immediately contacted the Information Commissioner's Office and brought in the National Cyber Security Centre and specialist experts to contain the breach. Multiple systems remain offline as teams work around the clock to restore services.

Cybersecurity experts warn this shows signs of a "serious intrusion" targeting councils' sensitive data including social care files, housing records, and identity documents. The attack highlights ongoing vulnerabilities in local government systems operating on tight budgets.
