EXPLAINED | Kudankulam data breach and the security of India's nuclea…

A data breach at Reliance Infrastructure, contractor for India's Kudankulam Nuclear Power Plant, exposed 14.3 GB of sensitive documents including reactor blueprints, control room layouts, and supplier lists held on commercial cloud servers. The incident reveals critical gaps in supply chain security oversight for nuclear infrastructure, with sophisticated ransomware actors gaining access to sensitive technical and strategic information about a Russia-supplied facility. If you sell cooling systems, ventilation, or power components to Indian nuclear contractors, your supply chain is now a known attack vector—and your customers are rewriting security mandates to match. The gap between the reactor core and the contractor's cloud server is where the next generation of critical infrastructure companies will either become essential or extinct.
