NPCIL: Kudankulam Leak Confined to Non-Nuclear Systems
The Nuclear Power Corporation of India Limited (NPCIL) has confirmed that a recent data breach involving the Kudankulam Nuclear Power Project (KKNPP) poses no threat to nuclear safety.
A ransomware group leaked 14.3 GB of data stolen from a third-party server belonging to Reliance Infrastructure, the contractor for under-construction Units 3 and 4.
NPCIL clarified that the compromised files are strictly limited to the Balance of Plant (BoP) common service facilities, such as ventilation and cooling layouts.
These components are conventional and identical to standard industrial or thermal power plants. Because the critical nuclear reactor systems—supplied by Russia's Rosatom—are kept on completely isolated networks, the core infrastructure remains entirely unaffected. While cybersecurity experts warn that the exposed blueprints could reveal supply chain logistics, India’s CERT-In is actively investigating to ensure the plant's operational integrity is maintained.
