Hackers are attacking Britain’s drinking water suppliers

Hackers have launched five cyberattacks against Britain’s drinking water suppliers since the beginning of last year, according to reports filed with the drinking water watchdog and partially disclosed to Recorded Future News under freedom of information laws.

None of the attacks impacted the safe supply of drinking water itself, but instead affected the organizations behind those supplies. The incidents, a record number in any two-year period, highlight what British intelligence warns is an increasing threat posed by malicious cyber actors to the country’s critical infrastructure.

The data shared by the Drinking Water Inspectorate (DWI) showed the watchdog received 15 reports from suppliers between January 1, 2024, and October 20, 2025.
