Hackers Target Britain’s Water Suppliers
Britain’s drinking water providers have faced five cyberattacks since January 2024, according to data obtained by Recorded Future News. While none of these incidents compromised the safety of the water supply, they underline growing risks to national infrastructure.
The reports, submitted to the Drinking Water Inspectorate (DWI) and disclosed under freedom of information laws, indicate a record number of cyber incidents in any two-year period. British intelligence has repeatedly warned that malicious cyber groups are targeting essential networks across the country.
Details of the Reported Incidents
- Five cybersecurity attacks occurred between January 2024 and October 2025.
- The attacks affected the organizations managing water services, not the water supply itself.
- DWI received a total of 15 reports from suppliers during this period.
- Five reports related specifically to cyber incidents involving “out-of-NIS-scope systems.”
- The remaining reports involved other operational issues unrelated to cybersecurity.
“The incidents highlight an increasing threat posed by malicious cyber actors to the country’s critical infrastructure.”
The DWI clarified that these submissions fall under the Network and Information Systems (NIS) Regulations, which form part of the broader framework for protecting Britain’s drinking water systems from technological risks.
Growing Concern Over Critical Infrastructure
Although water safety was not compromised, experts emphasize that these cyberattacks represent a warning sign for operators of critical public utilities. The trend suggests escalating attempts to test or penetrate the digital systems that support vital services.
