A serious cybersecurity incident has come to light in India. Ransomware group World Leaks has reportedly published nearly 19,000 files connected to the Kudankulam Nuclear Power Plant (KNPP), India’s largest nuclear facility in Tamil Nadu.
The leaked documents are said to include facility blueprints, supplier details, inspection records, and insurance papers. These files were allegedly stolen from a third-party server linked to Reliance Infrastructure, which is working on support systems for Units 3 and 4 of the plant.
Reliance Group confirmed a partial data breach on a server hosted by Yotta Data Services. The company informed the authorities immediately. India’s Computer Emergency Response Team (CERT-In) is now investigating the matter. The Nuclear Power Corporation of India Limited (NPCIL) is also in contact with Reliance.
While the full authenticity of the leaked files is still being checked, experts are worried. Such information could help hackers or other groups understand the plant’s layout and create security risks.
This is not the first cyber concern for Kudankulam. In 2019, malware was found on an administrative computer at the plant, though the main systems were safe.
The incident highlights the growing need for strong cybersecurity at critical infrastructure like nuclear power plants. Authorities are expected to tighten measures to prevent future breaches.
