Ransomware group World Leaks posted ~19,000 files from India's largest nuclear power plant (Kudankulam) including purported blueprints, supplier details and facility records on the dark web in June 2026. Contractor Reliance Group confirmed a partial data breach via third-party data centre Yotta and reported it to the Indian government.

This Wire brief sits within Fusion42's coverage of Cybersecurity.

◆ ◆ The Wire takeaway

If you supply power plant equipment or services to Indian nuclear operators, your customer's security posture just became a liability for you. Expect immediate audit requests and supplier vetting tightening as Reliance and NPCIL harden access controls.
