Data Breach at India's Largest Nuclear Power Plant

Ransomware group World Leaks has published 19,000 files from India's largest nuclear plant (Kudankulam), including purported blueprints of ventilation and cooling systems, supplier lists, and floor layouts of control rooms, after contractor Reliance Group suffered a data breach via third-party data centre Yotta. The leaked files could expose the plant's support systems, supply chain vulnerabilities, and security weaknesses to adversaries, though core reactor systems supplied by Russia's Rosatom appear unaffected. If you supply cooling, ventilation, or control systems to nuclear plants anywhere, your customer list and technical specs just became adversary roadmaps—and your next contract will require air-gapped security and supply-chain vetting you may not have built yet. India's nuclear expansion is accelerating (2,000 MW coming by 2027), but every plant now needs vendors who can prove they've survived scrutiny from state actors.
