A ransomware group named World Leaks has posted files linked to India’s Kudankulam Nuclear Power Plant on the dark web, according to reports from multiple outlets including Al Jazeera and Reuters. The leaked documents include blueprints of parts of its facilities and supplier details, though their authenticity remains unverified.

The Kudankulam Nuclear Power Plant, located in the southern Indian state of Tamil Nadu, is India’s largest nuclear power plant and a key component of Prime Minister Narendra Modi's plans to expand atomic energy capacity. The ransomware group labeled the information as coming from Reliance Group, one of the plant’s contractors.

Reliance Group confirmed a partial data breach on a server hosted by third-party Indian data center service provider Yotta and informed the government about the incident. However, they did not disclose what specific data had been breached. Nearly 19,000 files totaling 14.3 gigabytes have been online since June 11, according to independent cybersecurity researcher Rakesh Krishnan.

The Nuclear Power Corporation of India later stated that the breach did not reveal any sensitive information related to nuclear security. However, Nickolas Roth, a senior director at the Nuclear Threat Initiative, told Reuters that the data breach could pose a serious risk to the safety of the plant.
