A newly created forum account is claiming to possess approximately 40 GB of compressed data allegedly stolen from National Grid, the multinational energy infrastructure company that operates electricity and gas networks across the United Kingdom and parts of the United States.
The listing, posted on August 14, alleges that the archive contains source code, DevOps assets, cloud infrastructure configurations, and internal project documentation. At the time of publication, National Grid had not issued any public statement regarding the claim.
Claimed contents focus on development infrastructure
According to the forum post, the alleged archive includes source code alongside DevOps scripts used for CI/CD pipelines, Docker, and Terraform deployments.
The threat actor also claims the data contains ETL pipelines, SQL assets, Snowflake-related components, automated test files, cloud infrastructure configurations, and internal project documentation. The compressed archive is advertised as a .tar file with a reported size of 40 GB.
No evidence was provided indicating how the data was allegedly obtained, when the purported compromise occurred, or whether the material represents current production systems.
Low-confidence claim
The listing was posted by a newly registered forum account with no established history, making independent verification particularly important. Aside from the description of the alleged contents, the post provides little technical detail or supporting evidence regarding the authenticity of the claimed dataset.
If genuine, exposure of source code, infrastructure-as-code templates, CI/CD scripts, and cloud configuration files could present operational and security risks by revealing deployment workflows, infrastructure architecture, or other sensitive internal information.
BreachNews has not independently verified the authenticity of the alleged data or confirmed that National Grid experienced a security incident.
National Grid had not issued any public statement at time of publication.
