Data Breach Exposes Sensitive Files from Kudankulam Nuclear Plant In July 2026, the ransomware group World Leaks leaked approximately 19,000 files related to India's Kudankulam Nuclear Power Plant on the dark web. The data, allegedly sourced from Reliance Group, includes blueprints, supplier details, and inspection records. Reliance confirmed a 'partial breach' occurred on a server managed by third-party provider Yotta. The leaked documents date from 2016 to mid-2025 and are part of a larger cache of 858,000 files. While the Nuclear Power Corporation of India (NPCIL) denied any sensitive nuclear data was compromised, experts warn that the exposed information could assist hostile actors in planning cyber or physical attacks. Investigations are ongoing by NPCIL and India's Computer Emergency Response Team (CERT-In). The breach raises significant concerns about cybersecurity in critical infrastructure. 57 sources 68
